Metabones announced new series of Speed Booster adapters especially designed for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). The redesigned optics provide better sharpness when shooting with low aperture numbers. They come in standard versions – ULTRA 0.71x and XL 0.64x, and for Canon EF mount, Nikon G mount, and ARRI PL Mount. The adapters can only be used with the BMPCC 4K, they cannot be mounted on any other M43 camera. Speed Booster Adapters for BMPCC 4K. Source: Metabones Although there are now many lens adapter manufacturers, when it comes to Speed Boosters – adapters with optical elements – Metabones is still providing unmatched image quality. They offer a wide range of adapters for various lens mount and large number of SLR lenses. One of those adapters are Speed Boosters for micro four thirds cameras. These Speed Boosters can be used with the Blackmagic Pocket Cinema Camera 4K, but the image can sometimes get soft when shooting with low aperture numbers. That’s why Metabones releases new series of Speed Booster adapters especially designed for the BMPCC 4K. Metabones Speed Boosters for BMPCC 4K The new series of Metabones Speed Booster is especially designed for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). The optics were designed by Caldwell Photographic. The adapters come in standard versions – ULTRA 0.71x and XL 0.64x. Both versions are similar to the standard Micro four thirds Speed Booster adapters, but the optics have been re-designed to optimize for the filter stack thickness of the Blackmagic cameras, which is substantially thinner than that of standard M43 cameras.

If you want to know more about it, there is a useful article on Lens Rentals blog about it. The thickness of the camera’s filter stack is an important component of the overall optical design, and the re-designed optics ensure that the new Speed Boosters can achieve the same high performance with the BMPCC 4K as the Speed Booster versions for standard M43 do with other M43 cameras. As I mentioned, this is especially critical at wide apertures (fully open). Speed Booster Nikon G Adapter for BMPCC 4K. Source: Metabones In addition to the new optical designs, the new series of Speed Boosters also features a longer tripod mount to match the height of the BMPCC4K camera body. This way the camera and the Speed Booster can be mounted firmly on the same quick release plate. Speed Booster ARRI PL Adapter for BMPCC 4K. Source: Metabones Both versions – the Speed Booster ULTRA 0.71x and XL 0.64x – are available with Nikon G lens mount, with Canon EF lens mount and with Canon EF CINE lens mount. The ARRI PL lens mount is available in ULTRA 0.71x version only. The Canon EF CINE lens mount creates a positive lock for a secure electronic connection, and together with the matching length of new the tripod mount, allows for a rock-solid mechanical setup, which is important when using follow focus attachments.

According to Metabones, optical performance of the new Speed Boosters will even improve MTF of any lens attached to it. Here are the MTF charts with commentary taken directly from Metabones website. MTF Charts for the Spped Booster ULTRA. Source: Metabones All of the charts show the optical performance of the Speed Booster ULTRA 0.71x when mounted behind an ideal “perfect” lens. Figures 1 through 3 show MTF at 10, 20, and 40 lp/mm as a function of image height for output apertures of f/0.9, f/1.0, and f/2.0, respectively.  At the maximum aperture of f/0.90 (i.e., with an f/1.2 master lens) the sharpness and contrast are extraordinary across the entire image circle. At just one-third stop down to f/1.0 the performance is equal to or better than the best photographic lenses used at their optimum apertures. An additional stop down to f/2.0 yields performance that is rarely encountered in photographic optics. In practice, what all of this means is that the new Speed Boosters will always enhance and never degrade the performance of the attached master lens. Figure 4 shows that there is less than 1 stop of corner illumination falloff even wide-open at f/0.9. There is no vignetting at all after the output aperture reaches f/2.82. Figure 5 shows that rectilinear distortion added by the Speed Booster ULTRA is negligible at less than 0.7%.   The new Speed Booster XL 0.64x for BMPCC 4K uses 7-element optical design to achieve high optical performance at apertures up to f/0.80 (with a full-frame f/1.2 lens). Here are again the MTF charts with commentary taken directly from Metabones website. MTF Charts for the Spped Booster XL. Source: Metabones Figures 1 through 3 below show MTF at 10, 20, and 40 lp/mm as a function of image height for output apertures of f/0.8, f/1.1, and f/1.81. At f/0.80 (i.e., with an f/1.2 master lens) the sharpness and contrast are extraordinary out to an image height of 5.1 mm, which is the limiting image height of the BMPCC4K camera’s FHD video mode.  Beyond 5.1 mm the performance drops gracefully, but remains very good even in the extreme corner of the full Blackmagic sensor. Note that as the master lens aperture is reduced to f/1.8 and then f/2.8 (corresponding to output apertures of f/1.1 and f/1.8, respectively) the performance improves everywhere, especially in the extreme corners. Figure 4 shows that there is only about 1 stop of corner illumination falloff even at f/0.8. There is no vignetting at all after the output aperture reaches f/3.42. Figure 5 shows that rectilinear distortion added by the Speed Booster XL 0.64x is negligible at less than 0.8%. (MTF data is a full diffraction-based calculation that assumes the Speed Booster is attached to a perfect master lens having an exit pupil distance of 100mm.  Note that the MTF calculations do not take into account sensor-induced apodization effects, sometimes called “pixel vignetting” or “pixel shading”, so actual results at large apertures are likely to be better than the calculations indicate.) (Illumination data assumes a perfect master lens with an exit pupil distance of 100mm and zero vignetting.  The slight falloff shown at f/2.8 is due to cos4 effects alone, as the mechanical vignetting is zero.  Actual results will depend on the exit pupil distance and vignetting characteristics of the master lens used.) An important note – this new series of Metabones Speed Booster adapters is designed exclusively for the BMPCC 4K. They cannot be attached to any other M43 cameras such as JVC, Olympus or Panasonic. The BMPCC 4K Speed Booster adapters are now available for pre-order and the prices are between US $490 and $720 depending on the version. They should ship in mid August. Do you use some kind of lens adapter with the BMPCC 4K? How are you satisfied with the optical quality? Let us know in the comments underneath the article.

Metabones, a company that is known for making premium, innovative lens adapters, has just released their new Metabones EF to EOS M Speed Booster ULTRA 0.71x. This adapter allows you to mount full-frame Canon EF lenses on Canon EOS M cameras, while “increasing” the native aperture of the lens by one stop and reducing the crop factor by 0.71x. Let’s take a look at it!  Canon EOS M Cameras Initially launched in 2012, the Canon EOS M line of cameras never really drew too much attention. Many EOS M cameras were launched, like the EOS M/M2/M3, the M10 that we reviewed, and the latest EOS M50, which is currently the top-of-the-line camera of this ecosystem. The EOS M50 is a pretty decent camera, it features a 24.1MP CMOS APS-C sensor, and can record in 4K UHD at up to 25 frames per second, and in 1080P at up to 60 frames per second. It’s not the most excellent camera of all time, but if you are looking for something compact and intuitive, it can get the job done. Image credit: Tinh Khuong The real problem with EOS M cameras is the lack of quality native lenses. There are only four zoom and three prime lenses available in EF-M mount. Also, with the launch of the new line of EOS R mount cameras, I doubt Canon will continue to develop any new glass for the EOS M line. So – here comes Metabones with their new Canon EF to EOS M Speed Booster ULTRA 0.71x. Metabones EF to EOS M Speed Booster ULTRA Metabones is famous for making quality lens adapters. Back in 2013, they were the first to introduce an EF to E-mount “Speed Booster” adapter with a lens inside to reduce the crop factor of the camera and even more, increase the aperture of the lens by one stop. This new Metabones EF to EOS M Speed Booster ULTRA 0.71x is no different. It will reduce the 1.5x crop factor of EOS cameras down to 1.07x and make your lens one-stop faster. For example: it “converts” a Canon 24-70mm f/2.8 into the field-of-view of a 17-50mm f/2.0 on an APS-C sensor and a Canon 50mm f/1.2 to a whopping 35.5mm f/0.9 field-of-view. It is compatible with all full-frame Canon EF lenses. Also, it is compatible with EF-S lenses, but you’ll need to modify your glass, which may result in vignetting. When using the adapter, most of the features of the camera and lens are natively supported, like image stabilization and autofocus, except lens aberration correction. The EXIF metadata is changed to reflect the faster aperture and shorter focal length. Image credit: Metabones The Speed Booster ULTRA uses an advanced 5-element/4-group optical design by Caldwell Photographic Inc. that, according to Metabones, helps to “achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting.” Pricing and Availability A few adapters are already available if you want to mount EF glass on an EOS M camera, from companies like Canon, Commlite, Fotga and so on. But none of these adapters can do what the Metabones Speed Booster does. Only Viltrox has a Speed Booster for EOS M, but we don’t know about its quality as we haven’t touched it yet. The Metabones EF to EOS M Speed Booster ULTRA 0.71x is available right now for $479. What do you think of this new Metabones Speed Booster adapter? Do you use Canon EOS M cameras? Do you already own some Metabones lens adapters? Don’t hesitate to let us know in the comments!

In order to really transform your Sony FS7 / FS7 II into a real ENG camera, you have to employ some kind of  2/3″ zoom lens which is a versatile tool to use if you happen to shoot fast-paced reality shows or news programs. The new Sony LA-EB1 B4 mount lens adapter is exactly that. When combined with the CBK-FS7BK Build-up Kit you’re up to the task. But the resulting ENG-style FS7 won’t come cheap! A Sony FS7 II paired with a Fujinon ENG zoom lens. The vital link? A brand-new Sony B4 mount. Sony LA-EB1 B4 lens mount If you want to go on the ENG journey, you might want to take closer look at the new LA-EB1 B4 mount adapter Sony has announced, alongside the CBK-FS7BK build-up kit. With it, you can use regular B4 2/3″ ENG lenses with your FS7 / FS7 II and the nice thing is that this adapter only costs you 0.6 stops of light. What is the gain, you ask? Deploy any standard 2/3″ ENG style lens to the FS7 / FS7 II and your good to go. These lenses are not exactly cheap but compared to cine zooms with equivalent zoom ranges they come as a present. Sony LA-EB1 B4 mount adapter. While a B4 adapter for this camera is not a new thing, the LA-EB1 B4 adapter stands out here because it’s able not only to communicate with the lens attached and power it directly, but it also sends lens data straight to the viewfinder of the camera hosting it. So again, think ENG here: all the mission-critical information is right in front of you – without extra cable clutter and accessories. Fs7 II with CBK-FS7BK build-up kit and LA-EB1 E/B4 mount adapter (and a 2/3″ ENG zoom lens).  Pricing and Availability The LA-EB1 B4 mount adapter will cost you US$5.600 (5.000€). That’s a pretty penny, when the FS7 II already costs around US$9.000 (8.100€). Just as with the The CBK-FS7BK called build-up kit, the new B4 mount adapter won’t be available until December 2019. Plus, and that might be vital, the according Sony CBK-FS7BK build-up kit (V-mount / audio extension, shoulder pad/plate and dedicated EVF) already costs around US$7.300 (6.500€). So the grand total is about $ 21.900 (19.521 €), which is not cheap at all. A proper XDCam will cost you about the same but without an EVF and without the battery plate..

SLR Magic have developed the Anamorphot 1.33x -65 to include focusing gears, further expanding the follow focus functionality for anamorphic filming. For a few years now, SLR Magic has been a great choice for filmmakers aiming to achieve the look and feel of anamorphic, without spending lots and lots of money on high end lenses. However, due to the design of the adapter, it wasn’t possible to focus simultaneously with the lens itself or use follow focus units with it. (In his Anamorphot 1.33x -65 review, Johnnie explains the issue in details). Understanding the needs of the camera operator and focus puller, SLR Magic have updated the adapter with focusing gears, which has also lead to the possibility of using synchronized follow focus systems for both the taking lens and the anamorphot adapter. Mind you that this solution is not absolute in terms of focusing accuracy but as Andrew from SLR Magic explains in the above video, it is good enough especially considering the price of Synchronized Follow Focus Control unit and the lens being a T2.9 one. Synchronize Follow Focus Control With PDMovie A popular setup combination has been the FUJINON MK lenses and SLR Magic Anamorphot 1.33x 65, in which both the lens and adapter now have geared focus rings, but at different diameters. This poses difficulties when trying to achieve synchronous focusing of both units, this is where PDMovie comes in. The PDMovie Live 3 is a wireless follow focus system, that can synchronize both the Anamorphot adapter and FUJINON MK lens focus barrel rotation, even though both units have different angle of rotation and barrel size. It is possible to map the end points with the PDMovie Live 3 device, so both the lens and adapter stay synchronized when focusing remotely. Although there are quite a few synchronized follow focus systems available out there (from Chrosziel and Teradek for example), these are rather expensive. The PDMovie system is considerably lower cost. It would be great to see SLR Magic integrating the focusing gears into all of their Anamorphot adapters, which would take away the complications of attachable focus gear rings or manual focusing, especially as the lenses are being used on a range of productions up to high end. Would the updated SLR Magic Anamorphot 1.33x 65 adapter with lens gears solve your follow focusing problems? Does the PDMovie remote follow focus solution appeal to your needs? Let us know in the comments.

Last month we reported about the new Anamorphot 65, an anamorphic lens adapter by SLR Magic that can mount to lenses with 82mm front thread like SLR Magic’s own micro cinema primes and FUJINON’s MK family of lenses. There is also a chance that by the time you read this review, this promising adapter will be available for preorder.  SLR Magic Anamorphot 65 anamorphic adapter on a Sony a7 III camera Nino, my colleague, caught up with Andrew from SLR Magic during this year’s CineGear to discuss the new product, yet it was time to actually test it and put it through its paces. The Anamorphic Lens Routine First thing first: Why should one actually consider “shooting anamorphic”?, well, the answer is clear. If you are looking to mimic the true aesthetic of cinematic looks, then shooting with an anamorphic lens is the way to go. As this is a product review I will not go deep into the subject anamorphic filming, but please consider heading to our cinema5D essentials episode where Li-Lian and I were aiming to explain what anamorphic filming is all about…. Ok, so if shooting with anamorphic lenses has the benefit of producing a unique look, why is it not too widely spread? In short: budget and training. TRUE high quality anamorphic lenses simply coast A LOT, far beyond the budget of most independent filmmakers. There are, of course, ways to track and purchase vintage anamorphic lenses, but this is not too easy. Speaking of anamorphic – I urge you to visit our friend and content contributor, Tito Fernandez’ YouTube channel, where he demonstrates a great deal of knowledge and shares valuable tips for anamorphic lens and adapter lovers. The question remains: If true anamorphic lenses are expensive, what is the next best option? The answer is, “adapters”. The idea of putting an anamorphic lens adapter in front of spherical lenses is nothing new and can actually make a lot of sense, as most of us already own many of those wide spread zooms or primes, so why not make use of those and attach an adapter to them? (I’ll leave this question open, hoping to hear answers from you guys in the comment section below). In the past, I’ve already tested SLR Magic’s entry level anamorphic adapter, the Anamorphot 40 compact adapter, but besides the fun I had exploring shooting in anamorphic, this specific adapter left me feeling that probably, there are no shortcuts when attempting to create a high quality device. SLR Magic Anamorphot 65  The SLR magic Anamorphot 65 The new Anamorphot 65 is a completely different story. First the specs: 1.33x adapter to be used with modern cameras having a 16×9 sensor image size Rear Mounting Thread 82mm, perfect to be attached to SLR Magic Micro Primes, some SIGMA lenses, and the FUJINON MK 18-55mm and 50-135mm Outer 112mm diameter thread for optional filters Outer 114mm diameter barrel for attaching a matte-box Weight: 1.7 lb / 0.78 kg SLR Magic Anamorphot 65 112mm filter thread The FUJINON MK 18-55mm and MK 50-135mm  The above two FUJINON MK lenses were introduced about 2 years ago and since then, managed to capture the heart of many filmmakers. The quality for their price is great and their size and weight is perfect for many shooting occasions. I’ve tested the adapter on the E-mount version of the lenses, but this is the place to remind everyone that FUJINON will soon start shipping their own X-mount version of the lenses, bearing some extra benefits for users, as the lens will be able to communicate with most FUJIFILM camera bodies. Speaking of which, there are modified FUJINON MK lenses to M4/3 mount, so practically speaking, those lenses will fit on Olympus or Panasonic cameras too. The SLR magic Anamorphot 65 was built with both mentioned lenses in mind and I have to admit that mechanically speaking, the fit is perfect. Set your full frame camera to APS-C/Super 35mm option Attaching the Anamorphic Adapter to the FUJINON MK Lens For best optical performance, please perform a lens back focus check prior to attaching the lens adapter to the FUJINON lens itself. Right after, the  procedure of putting the adapter on the lens is fairly easy, although, for whatever reason, it was a bit easier for me to attach the adapter to the FUJINON MK 50-135 than to the MK 18-55. After the attachment, make sure to place your camera and lens/adapter on a flat surface to ensure correct aligning of the adapter and lens. On the camera front – if working with a full frame camera like the Sony a7XX – don’t forget to change to APS-C/Super 35mm in the menu settings. As a side note, it is unfortunate that there is no “de-squeeze” function in those Sony a7XX cameras, as what you see in the LCD/VF is NOT what you get! On the positive side, since the adapter is lightweight, it is possible to work handheld and even without lens support, although if you do have the opportunity to add support, please do so. Photo exported from the timeline. Quality of the adapter glass “off-center” is good too! The SLR magic Anamorphot 65  – Lens Adapter Performance For the last few days I was running around equipped with the Sony a7 III, two FUJINON MK lenses and the adapter. I can report that I liked what I saw, but with some reservations. In terms of which lens to use, the FUJINON MK 50-135 looks to be the obvious choice, as its complete focal length can be used when the adapter is attached to it. The thing is that the starting point of 50mm is too narrow for my taste and in addition, sharp focusing was extremely challenging for me and as a result, much of the footage I took when using this lens, seemed to be a bit off. Now, switching to the FUJINON 18-55mm, it was as if the adapter just got a new life. Although focusing was not always easy, (more about that in a second), the images I was able to capture were simply wonderful. I really like the fact that the adapter is able to keep sharpness almost from edge to edge. So where’s the catch? As predicted, you can not use the complete offered lens focal length but rather a part of it, starting at 30mm – which is almost perfect for anamorphic work. On the narrow side, 55mm is a bit to short, but for planned projects, where you have the possibility to be closer to your subject of interest, it will certainly do. Dual focus necessity. Lens and Adapter. Distance markers are matching The SLR magic Anamorphot 65 – Main Concern So far so good, but as with many other products, there is this little (big) thing that makes the overall user experience, when using the lens adapter, far from being perfect. It’s the double focus procedure necessity, meaning, focusing must be preformed on both, the lens and the adapter itself. The good news are that the marking on both is very similar and as the anamorphic adapter was made with the FUJINON MK lenses in mind, the alignment is perfect, so if your focus mark on the lens is 10ft. just turn the adapter focus ring to the same number value in order to achieve perfect focusing. It’s not that we haven’t seen it before, but in this case it is simply a pity, as it does take time to focus both. Moreover, there is absolutely room for mistakes. I really wonder if it is possible to build a “custom handle” that can be attached to the lens focus ring on one side and the adapter focus ring on the other, in order to simplify the process of focusing. (Sorry, I can’t think of a solution to make the life of focus pullers any easier)… SLR Magic Anamorphot 65 on a FUJINON lens. My favourite is the MK 18-55mm Conclusion This time I’ll base my conclusion on three points: Price, usability and optical performance. Price is a subjective thing. I do think that for what you can get when working with this anamorphic lens adapter, the price is manageable. Usability is were this attachment scores the least. It is the double focus procedure that will slow you down when working and on top, might cause some hesitations when focusing during filming (and lets face it, as the resolution goes up, the days of soft images are numbered)… When it comes to optical performance, I really like what I saw (I especially salute SLR Magic for staying in-line with the FUJINON’s MK lenses’ performance and not choosing to go the “crazy flares” path). The combination of SLR Magic’s Anamorphot 65 together with the FUJINON MK 18-55mm is perfect to use when budget is a concern yet an anamorphic look is desired. Now I just need to invent something to focus both at the same time…. The above video was edited on Adobe Premiere CC latest edition.

The popular FUJINON MK lenses can now be adapted to Micro Four-Thirds and FZ mount thanks to Duclos Lenses and MTF Services. Since their release earlier in the year, the FUJINON MK 18-55mm T2.9 and 50-135mm T2.9 have been a very popular choice for E-mount camera users on the FS5 and FS7. Their versatility in focal length and aperture makes them ideal for anything from independent filmmaking to documentary-style shooting. This versatility is now coming to Micro Four-Thirds, Sony FZ mount and FUJINON X-mount cameras, opening up a new range of possibilities for owners of the Panasonic GH5 up to high-end production cameras like the Sony F5/F55/F65. In the UK, MTF Services can adapt both FUJINON MK lenses to Micro Four-Thirds and FZ mount systems. There is no pricing currently listed, and you would need to ship your lenses to MTF Serives. For more information visit the MTF Services website here. Duclos Lenses are also offering the conversion service from E-mount to Sony FZ mount in the form of a DIY kit, which can be purchased for $500.00 through their web store here. Both FUJINON and Duclos Lenses have stated that this is a like-for-like mount replacement with the same screw configuration. FUJINON will also be supporting the X mount for cameras like the X-T2 in the future, increasing the compatibility of the lenses with its own brand cameras. Unfortunately there is no possibility for these lenses to be adapted to EF mount, as FUJINON has stated this is physically impossible. Are you a Micro Four-Thirds or FZ-mount camera user interested in using the FUJINON MK lenses for your filming? Let us know in the comments.

The Fotodiox DLX Stretch lens adapter adds ND filters, macro magnification and aperture control for manual lenses. Fotodiox has been a popular choice for lens adapters, offering various options that aren’t as costly as those from Metabones. The newest addition to their line-up, the DLX Stretch series, is much more than just a bare-bones lens adapter. In addition to adapting your lens for use on a different camera body, it also introduces three extra features: a lens barrel extender to achieve macro magnification, manual aperture control for Nikon lenses and most interestingly, drop-in magnetic ND filters. The macro magnification feature works by turning a dial on the lens barrel, causing it to extend. This pushes the lens away from the sensor, creating a macro effect with any lens. This is similar to how extension tubes work, but in this case it all happens internally in the adapter itself. In the Nikon version of the lens adapter, a built-in aperture control has been added for Nikon lenses that have no manual control. If you are using Canon lens, It’s important to note here that Fotodiox recommends only using manual Canon EOS lenses, as there is no electronic control from the adapter to change aperture in camera. Lastly and probably the adapter’s most intuitive feature, is the drop in magnetic ND filters. These are placed in the rear mount of the lens to stop down the exposure, ideal for achieving shallow depth of field in bright situations, or for Sony mirrorless camera users shooting in an S-Log profile which requires a higher ISO. The DLX Series includes ND4/8/16 in the package, but more ND filter stops will be coming soon. The filters sit snugly in the rear mount of the lens and need a nudge or shake to remove them. The Fotodiox DLX Series adapters are available for a number of lens mounts and body mounts, which include: Body mounts: Sony E Mount, Micro Four-Thirds, Fuji X Mount. Lens mounts: Canon EF, Canon FD, Contax/Yashica, Leica R, Minolta MD, Nikon, Olympus Zuiko (OM) and Pentax K. Price wise, at $129.95 the Fotodiox DLX Series adapters are certainly affordable in comparison to products from other manufacturers. However, due to the lack of electronic control, features such as autofocus or image stabilisation will be unavailable to you and you are mostly going to be limited to using manual lenses. You can see the Fotodiox DLX Stretch in action in the video below. For the full range of adapters, check out the Fotodiox website. Does the Fotodiox DLX Series adapters give you the extra features you need for shooting with a mirrorless camera?

Chinese manufacturer Venus Optics has just released a new lens adapter called the Laowa Magic Format Converter. With it you can use your existing full-frame Canon or Nikon glass on the mighty sensor of the medium format Fujifilm GFX 50S camera. Let’s have a look! The Laowa Magic Format Converter The Medium Format Fujifilm GFX 50S Camera is Finally Here and Shoots Video. That was the headline of our first article about this stunning medium-format beast from Fujifilm (check out the article here). Unfortunately, that superior sensor has a major downside built right in: it’s sheer size renders your existing full frame glass useless since the smaller image circle would produce massive vignetting. The solution? Well, meet the Laowa Magic Format Converter by Venus Optics. You might think of calling it a Speed Booster, but that is not quite the case here since it’s actually more of a Speed Shrinker. A Speed Booster will shrink the image circle produced by a full-frame lens in order to fit, say, a Super 35mm sensor, acting as a magnifiyng glass which is why the image becomes brighter. As a a result, you gain an extra stop of light hitting the sensor. Conversely, the Magic Format Converter is designed to increase the size of the image circle a full-frame lens is capable of rendering, allowing it to cover the huge medium-format sensor of the Fujifilm GFX 50S camera. The downside is a decrease in incoming light because the same amount of light needs to be spread out over a larger sensor area. As a result, you’ll lose one stop of light. Image Quality Although the Magic Format Converter isn’t quite ready for shipping, the results already look very promising! There’s no visible vignetting and the overall sharpness seems to be very decent. Oftentimes, the peripheral image sharpness gets pretty degraded when using low quality adapters. No vignetting! Read all about this new Magic Format Converter over at venuslens.net. You can find lots of comparison shots there and you can even download the RAW files for further inspection. Pricing and Availability Pricing hasn’t been set yet but the Magic Format Converter should be ready soon, and is expected to start shipping in July 2017. The Adapter will be available in two versions: Canon EF to Fujifilm G and Nikon AI to Fujifilm G. Several Laowa lenses on the Fujifilm GFX 50S using the Magic Format Converter. Also, the engineers over at Venus Optics seem to be eager to improve the adapter even more. Therefore, they are seeking Fujifilm GFX 50S owners in order to gather feedback: We are currently inviting volunteers who owns a Fujifilm GFX 50S to test and jointly make this adapter a better one. If you are interested, please send us more information about yourself via email. [email protected] What do you think? Is it time to jump on the medium format train?
