Zacuto Gratical firmware 3.3 update adds new settings to display features. The Zacuto Gratical is a go to EVF for video monitoring, with OLED displays that aid in focusing and composition. These latest updates fix a couple of bug bears. The updated features include – Battery meter can be turned off when flashing red. Pixel to pixel indicator information are will turn red when it’s active. Peaking no longer activated when monitoring with the colour bars or Macbeth chart. Joystick control will flip when the ‘image flip’ is activated. Follow this link to download the new firmware upgrade, or for more information on the update, check out the Zacuto support page. Please be aware that this firmware is not compatible with the Gratical Eye, only the HD and X models.Read more
Zacuto just released their lightweight (i.e. smaller) version of their Gratical viewfinder – the Gratical Eye. I was able to take close look at it before its release. Ever since cameras started coming in weird forms and shapes, including the dawn of the era of shooting with DSLRs, there has been a need to make them work like proper video cameras. In this respect, one enormous downfall of many cameras has been the inferior digital viewfinders featured – or the complete lack of one! There have been various manufacturers seeking to make camera-agnostic viewfinders that can be used on any camera, regardless of the manufacturer – Alphatron, Cineroid, LCDVF and SmallHD to name a few. Not many have managed to build them small enough (using OLED technology that is required for a small build) to qualify as a proper viewfinder, rather than a loupe attached to a small monitor. When Zacuto released their Gratical HD (and later the Gratical X) viewfinders, it was clear that here was a manufacturer that finally tried to address most if not all concerns of users with viewfinders. Sharpness which allows for proper judging of focus, built-in preview LUTs for all types of popular cameras, proper waveforms, histograms, peaking, zebra and even SDI and HDMI in and outputs. The Zacuto Gratical HD has been my viewfinder of choice for most of my productions since it was released, and it hasn’t let me down yet (read my full review of the Gratical HD by clicking here). What set the Gratical HD and X apart from the other camera-agnostic viewfinders on the market was its cigarette-box shape and relatively slim body compared to the others – meaning you can also move it closer to the camera which is always a plus. Yet if you had to name a downside to it, it would have to be its size and hardware features which actually require it to be a bit larger. The SDI and HDMI loop-through take up a lot of space up top. Built for who? The challenge with building accessories is always to please everyone – it’s impossible. Many people have different requirements, and the Gratical HD and X were definitely built with people that use them on smaller cameras in mind – especially those that might not even have multiple SDI or HDMI outputs, which is why the Gratical multiplies them, at the cost of size. To use it on those cameras (which often have weak batteries) it also makes sense to self-power the device using industry-standard Canon LP-E6 batteries. But what about the people using larger cameras to already have enough connectors plus the ability to power external devices? I’m sure that was the reasoning that the Zacuto people had in mind when they came up with the Gratical Eye. A Gratical family This newly-announced addition to the Gratical family looks very different from the HD and X; it’s much smaller and shaped like a ball. It feels extremely well-made in your hand, and the first impression I got was one that is usually something that I only get when looking at an Apple product – perfect design for what it is, well crafted with meticulous attention to detail. It just feels great – and you will have to hold it in your hands yourself to fully understand what I mean. Size comparison: Gratical Eye vs. Gratical HD Gratical Eye hardware features Its minimalistic approach means it has fewer hardware features than its larger siblings. No battery, only one SDI-in and no HDMI. Clearly targeted at higher end shoulder cameras like the Sony FS7, F5/55, Canon C300 Mark II, Panasonic Varicam 35 and LT, Red Dragon/Weapon, Alexa Mini and so on. Where you put the wires on external devices is always a big issue and I’m happy to say that Zacuto managed to find the least cumbersome place at the bottom backside of the Gratical Eye. A Lemo power connector with a D-Tap on the other side, paired with an SDI cable in a flexible unified cable works a treat and leaves your camera free from cable mess. Other hardware features include a USB port for firmware and feature updates (and Zacuto has been patiently adding features to their Gratical viewfinders consistently since they were first released), and a tally light that gives a clear red indication when the camera is recording. It has Arri rosettes on either side, ideal to be attached to a camera with Zacuto’s Axis Mini mount which has enough flexibility to put it very quickly in the right position depending on your setup. Zacuto removed the 3/8 inch thread at the bottom as seen on the Gratical HD and X, probably due to space issues on the smaller device. Gratical eye looking through / software features Let’s put it this way – if you know the Gratical HD and X, you will know the Gratical Eye. I made a few comparisons between the two, and the image looks identical in most cases. I couldn’t spot a difference, at times the Gratical Eye only seemed a little brighter, but this might have been my imagination. It has the same edge-the-edge sharpness with very little distortion on the edges. The image is the same square image at 1280 pixels wide, with additional image information like waveforms using up the area below the actual camera image. Like I said in the original Gratical review, 1280 pixels is a resolution high enough to critically focus 4K footage as long as you use the included peaking functionality to your advantage. For a run-down of all software features, please refer to my original Gratical HD review. Everything except for the loop-through functionality is identical. The final version of the Gratical Eye will have a proximity sensor, which switches off the display whenever you are not looking through the viewfinder. This functionality was not finished in the prototype version that I tested. Powering the Gratical Eye As mentioned above, the Gratical Eye is powered through a 2-pin Lemo to D-Tap cable (I’m sure they will offer other connectors too). It’s a convenient and smart solution to use external power, one thing less to worry about. When testing, I left the unit plugged into a D-Tap port on an FS7 overnight after I powered the camera off. When I came back to the camera about 20 hours later, the battery was completely drained. I reached out to Zacuto to share my findings. Here is their response: We will have a sleep mode that activates after an hour of no use. Sleep mode will still drain power but at about half the rate. Right now it drains a 100W/hr battery in about 20 hours. In sleep mode, that would take closer to 50 hours. Or 60% of a 100W/hr battery in 12 hours, compared to sleep mode draining closer to 25% of the battery in the same amount of time. So this is something that needs to be considered – I would just detach the power connection when I am done with my shoot or on longer breaks. Conclusion The Zacuto Gratical Eye is a very high-end digital viewfinder with most of the bells and whistles of its larger sibling, the Gratical HD while being smaller and lighter, at a price between the Gratical X and Gratical HD models. It’s not a cheap device, but I wouldn’t say it’s expensive either. If you compare to Sony’s F55 viewfinder, which only works with that camera – or even the Blackmagic URSA viewfinder – it’s still a great deal because of all its built-in features plus the fact that it simply works well with every SDI camera as opposed to the other models. Its size and shape will make it blend in seamlessly with both smaller and larger camera packages.Read more
Zacuto released its highly anticipated Gratical HD EVF this year (check out our extensive Review), a professional OLED viewfiner with lots of advanced features. As a budget friendly alternative Zacuto just announced the new Gratical X viewfinder, a version of their OLED EVF starting at $1650. Zacuto’s first OLED EVF, the Gratical HD is now getting company with the new Gratical X. Both units have the same hardware specs (full micro-OLED display with built in diopter). The models differ only in software. The Gratical HD EVF comes with all the professional features like Vectorscope, Waveform (3D), Histogram, LUT import et cetera. The Gratical X Micro OLED EVF on the other hand comes only with a basic feature set (HDMI and SDI inputs, display adjustments, color bars, blue gun) and you can purchase additional features individually. These features will need to be purchased at the Zacuto website (coming soon). The Gratical X OLED EVF can be pre-ordered and will cost $1650. Shipping is scheduled for the end of July 2015 in limited quantities.Read more
Zacuto has added compatibility for the Canon C100 Mark II to its next generation Recoil rig. The Zacuto C100 Mark II Recoil utilizes the existing VCT baseplate, Grip Relocator, Axis Mini, Gratical HD and finally a new C100 Mark II Helmet. Many will be well acquainted with the existing Zacuto Recoil components. The Universal VCT Baseplate offering a wide level of adjustment, Axis Mini arm that holds tension yet still offering adjustment, Canon Grip Relocator that re-assigns the Canon side handle to position of your choice. However, I want to talk about the new addition; the Canon C100 Mark II Helmet. This builds on the C300/C500 Helmet Zacuto designed a couple of years ago, mounting to the existing hot shoe mount of the camera and grabbing additional stability from the thread of the film plane screw (whilst offering another thread port for the film plane screw thus preserving its function). Mounted to that is a rail with 15mm rod mount on the end for attaching adjacent accessories (perfect for EVFs) and on top a double dovetail join that connects the Canon handle whilst offering plenty of fore and aft movement to refine balance of your handle and rig. Canon C100 users will all tell you, the connection between the handle and camera body is pretty poor. Even at maximum tension there is a large amount of play in the joint. Zacuto solve this issue by reversing the mate. The ratchet lever compresses into the cold shoe of the handle (rather than the pin screwing down) which full firms it all up. With full adjustment of both the handle location and the camera on the VCT Baseplate you are able to achieve perfect over the shoulder balance with most lens configurations (large lens setups may require rear counter balance). As a C100 user myself, I like the look of this. The Helmet as a stand-alone product is great for mounting EVF or recorders like a Ninja Blade to the side of the camera. I have a similar solution from Wooden Camera that also works great. However it does not solve the frustrating loose handle to camera body issue. Additionally you can purchase a Mount Bracket for the C100 Mark II that acts as a spine to the existing handle, offering 1/4″ and 3/8″ threads plus another 15mm connector. The Zacuto C100 Mark II Recoil comes in few configurations, you can buy all parts separately, or as the EVF Recoil (Baseplate, Grip and Helmet) or Gratical HD Recoil (same but with Gratical HD and Axis Mini). Speaking of the Gratical, the HD EVF has just received a firmware update. Here’s what you can find in firmware 2.0: New peaking feature has been added to the menu overlays->focus assist->reg peaking Activating red line peaking will no longer make the image lose sharpness Image flip will now stay active after a power cycle Fixed a bug where the image would appear to jump or change positions Fixed a bug where the image’s contrast or brightness appeared to change Changed the FS7 Slog3 to Rec709 preset LUT Added compatibility for Nikon D800/D810 cameras Added compatibility for Wooden Camera C-Box Converter Fixed a bug that would not allow a user to create a custom DSLR scaling Decreased the audio meter latency The Gratical HD really is a fantastic bit of kit; if you get a chance at any up coming shows it’s really worth checking out to see for yourself. Further more was Zacutos announcement earlier in the month at Cinegear to offer a “Gratical-X” package, this is basically a selectable package with a price based purely one the features you want it to include. The results mean you can the introductory price of the Gractical HD drops dramatically from $3100 to around $1600. Software packages ranging from $300 to $700 then spec up your EVF according to your required features. via/ Zacuto & NewsShooterRead more
If you have been in the business for a while as a cameraman already, you might remember a time when there were cameras that you could just pick up for the first time “out of the box” or from the TV station that hired you and you were able to use it “as is”. Amount of different cameras Nowadays, the amount of different camera brands and models that we are using as professionals on a daily basis is constantly increasing. The average professional has a number of different cameras he’s working with, or hires them on occasion. There isn’t “one camera for the right job”, there’s loads of different ones for loads of different purposes. For example, I still use my Canon C300 for many broadcast jobs as it’s an extremely popular camera with a beautiful image. Since it was released, I have also become a big fan of the Sony A7s, an amazingly small full frame camera with the most insane low light capability you have ever seen. I also ordered the Sony FS7, which will be my first permanent foray into 4K filmmaking, and I frequently hire an F55 or Red Epic or Dragon for higher end jobs. And sometimes (rarely though) I am even forced to work with traditional shoulder-mount broadcast cameras like the Sony PXW-800. As you can see, that’s a huge range of cameras. The problem with that is that they come with viewfinders that differ hugely in quality and size. Also, they take some getting used to until you really confidently are able to focus with them. Oddly, in recent years, smaller cameras like the A7s seem to have better viewfinders than more “professional” cameras like the C300, for example. Sony has been pushing their OLED technology even into smaller and cheaper products like the A7 line and others, and they are superior to LED because of their reproduction of blacks, resolution and coming in at a small size. Quality and compatibility of EVFs When I tested the FS7 on my recent shoot on Vienna’s St. Stephens Cathedral (click here if you missed it), I was in a big hurry and couldn’t find a quick way to use preview LUTs on the supplied viewfinder, so I had to shoot looking at SLog 3 … and if you ever did that, you know that it’s extremely hard to judge focus (or color, for that matter) if you look at an Slog or C-Log image, while it gives you most latitude for post production. So I ended up with some images that are out of focus simply also because I didn’t know the viewfinder well … and this is something that can easily happen to you if you hire cameras with a supplied viewfinder, especially if they are not very good … When DSLRs first came out, we had the problem that the built-in viewfinder couldn’t be used for video, so we had to add loupes like Zacuto’s popular Z-Finder to magnify the image displayed on the back screen. This helped tremendously but on cameras like the Canon 5D Mark II, judging focus was still very hard because of the low resolution of the screen – at least the camera’s soft video images weren’t as susceptible to focusing errors as more modern cameras. Also, it was often hard to judge the displayed image in its entirety due to the magnification of many of the added loupes – the Z-Finder was no exception. With sharper HD and now even 4K cameras the resolution problem became more prevalent. There are terrible EVFs or viewfinders on some very popular cameras, namely the C100 (Mark I, the Mark II has a better one, as does the C300), Sony F3, FS100, FS700 and many others. The FS100 and FS700 use a low quality screen with a lousy and long detachable loupe, impossible to judge focus on an HD image properly. It becomes of course much worse if you record 4K with the FS700 … an absolute nightmare and simply a gamble to get things in focus. In general, if you ever had the chance to look at shallow depth of field 4K footage on a 4K screen, you have certainly realized that focusing is incredibly hard to get right – not just in that resolution, but it’s especially hard the higher the recorded resolution, obviously. Nevertheless we mostly judge focus using low resolution viewfinders …. One viewfinder for all cameras? And this is exactly where the Zacuto Gratical comes in as an extremely interesting proposition … with the promise to work on almost every camera. When Zacuto announced the development of their high-resolution viewfinder a few years ago, many realized that it was time for such a product, but we had for a long time for the final product to arrive. And oddly enough, there aren’t many products on the market that can even be compared to the Gratical. There are the Alphatron and Cineroid viewfinders, which are much cheaper, but made predominantly for DSLR shooters in need of an external viewfinder. The problem with both of them is their sheer size – both use relatively big LCD screens combined with a loupe, and the resolution isn’t that great either (rumor has it that they use the retina screens used also in iPhones). Zacuto also made their original Z-Finder EVF, which combined a small, lower resolution screen with the Z-Finder loupe. While all of these viewfinders weren’t bad, they weren’t great – so why didn’t anyone come out with a smaller high resolution viewfinder compatible with all kinds of cameras before? The answer is simple: availability of the screens just wasn’t there. There are only few companies in the world which produce high quality screens in really small sizes and in quantities, and the comparably small niché of camera accessories simply wasn’t among their priorities. Plus the Alphatron and Cineroid viewifinders also were too big for my taste (among many other issues I had with them), especially when used with a small camera. The shape of the Gratical makes much more sense when put next to any camera – a longer, slimmer design that can move very close to the camera allows for much more flexibility. Sony came out with a really good OLED viewfinder for their F5 and F55 and I quite enjoy working with it whenever I use any of those cameras. However, there’s a big downside – it uses a proprietary connector and isn’t compatible with other cameras at all – not even the new FS7! Incredible for a $5,000 device, which makes the Zacuto Gratical look cheap in comparison. Gratical build quality To be able to use one really good viewfinder with all kinds of cameras means that there is no need to to readjust yourself to the “look” of different monitors and viewfinders constantly, and that’s a huge plus in this age of constantly changing cameras. Before I talk about the individual features of the Gratical viewfinder, I want to mention its build quality, because that’s what I had most problems especially with on the Alphatron viewfinder in the past. I was always worried that the thing would break apart at some point. Not so much with the Gratical. It seems to be build like tank out of very sturdy material, and Zacuto backed that up recently with running it over with a car in a very American fashion :-) It really feels like something that can take a beating, and when I am spending that much money on something, I usually also want to make sure that I can hire it out to other filmmakers – and the Gratical really feels as sturdy as a rental item has to be. It’s built out of Aluminum Alloy, just like an Alexa EVF, which also makes it super lightweight. Other Zacuto electronics like the original Zacuto EVF were build quite well too, but you can tell that a lot more money went into making the Gratical when you hold it in your hands. It feels like something really valuable and I can’t see any piece break off easily … Aluminum feels like the way to go for things like that! It also has rubber over all its sensitive parts, namely the glass and the connectors. While I have to admit it looks a bit funny when cables are connected to it (with all the rubber protectors sticking away from it), those rubber protectors really do a good job when a connector is not in use. Plus you can’t lose them because they are attached to the Gratical. Gratical form factor and rigging The Gratical is an OLED viewfinder, which means it doesn’t have a larger LCD that can be used as a screen like on the Alphatron, Cineroid or the FS7 viewfinder. However, that doesn’t really matter to me at all – as mentioned before, I prefer a smaller unit over a wide unit with an LCD screen, especially on smaller cameras. Zacuto have a lot of experience with building rigs, obviously, and because of the Gratical’s narrow shape, it can be put up quite closely to the side of a camera, which is perfect when you build up a rig. Try that with an Alphatron, good luck! Same problem with the FS7’s supplied viewfinder – the mounting solution that Sony added for the supplied viewfinder is atrocious … and it’s very hard to get in the right position. The Gratical on the other hand comes with an industry standard Arri Rosette on the side, which works great with the Axis EVF mount that makes it very adjustable to any position. You can also use a standard 1/4 inch screw at the bottom alternatively. There are also 4 assignable (or re-assignable) buttons on the side of the unit as well as a joystick with another 4 assignable positions (until you push the joystick – then the four directions on it serve as the menu navigation). The cool thing is, all of these buttons can store really ANYTHING the Gratical can do. You can even program a LUT onto one of the buttons and switch between LUT and LOG image by the press of one button. Extremely neat and VERY useful! Powering It’s nice to see that the Gratical works with standard Canon LP-E6 batteries, which everybody already has. They seem to last for a many hours … how many exactly, I don’t know, but one LP-E6 battery got me through a full afternoon when I tested it, easily 4 hours, and it wasn’t fully drained when I stopped working with it. I didn’t use any of the jacks and no loop through, but according to Zacuto you get 3 hours constant run time if you do use all the features and ports at the same time. That’s pretty good for these small batteries – the OLED technology seems to require considerably less energy than LCDs. The battery mount is very well designed and deeply integrated into the Gratical, which is great – there is no chance of accidentally knocking off the battery like on some other viewfinders, especially the early models from Cineroid. Zacuto also has a LP-E6 to D-Tap cable that can directly go into any battery with a D-Tap port, for example the Anton Bauer batteries. Considering these big brick batteries are standard on larger camera rigs like the F5/F55 and all sorts of traditional broadcast cameras, you never need to worry about powering the Gratical again. Ports The Gratical HD has two HD-SDI ports (in and out) and two HDMI ports (in and out). It allows you to loop through an image to an additional device. For example, you can attach a wireless HDMI transmitter to the Gratical (which gets its video feed from the camera, of course). You could send the video signal to video village like I frequently do using something like the Radian MC transmitter (read my review here). If you attach a recorder at the end of this chain, just be careful to disable overlays which would otherwise end up being burnt into your image. Screen and resolution The first thing you notice when you look through the Gratical HD is that the screen is almost square instead of 16 x 9. It’s 1280 by 1024 resolution, and it is devided into two sections. There’s the image area covering 1280 by 720 pixels used for the image, and a technical area that is used for vectorscopes and other additional image level information by factory default. However this section is completely user-definable as well – it can be displayed either on top or at the bottom of the image area, and it can also display information like audio meters, battery level and any other feature the Gratical has – so it’s fully customizable. Apart from the great customization, I think that’s a really smart idea to separate the technical information from the image – there is hardly anything more annoying than a preview screen cluttered with overlays, making it impossible to judge the image. 720p resolution might not sound like a lot, but in fact it’s more than what most viewfinders offer – in fact I wasn’t able to make out individual pixels at all. Quite the contrary, I am usually a guy who loves to use red peaking to be able to judge focus better – not with the Gratical though (although of course the feature is there). It’s simply not necessary. If the diopter is adjusted correctly (double check when you use it!), it’s super easy to judge focus purely by looking at the image. I really never had this kind of experience before using a viewfinder – the one that came close was the proprietary Sony OLED viewfinder for the F55, however I found that viewfinder to have shutter issues (apart from the fact that it only works with the F5 & F55 cameras like mentioned before). Color reproduction & LUT / Picture Profile When I attached the C300 for my test of the Gratical HD, I realized that the color reproduction was very accurate – accurate to reality, not necessarily to the camera (which is a good thing for a viewfinder!). The Gratical has extensive controls for color balancing, so I am sure it can fit every need – nice are also the color presets which can safe adjustments for different cameras. The LUTs feature wasn’t working on my review loaner when I had it, but Zacuto explained to me how it will be working (with the firmware update to be released very soon): – import – can import lut from Resolve as .look as well as many other LUT files and save to one of 16 presets in the Gratical – create – can create a lut internally and save to one of 16 presets in the Gratical – EVF Internal LUT – either select a preset lut for your camera (created by Zacuto), B&W, or any of your 16 presets saved in the Gratical – SDI out LUT – Exactly the same as the EVF LUT except can be a totally different LUT going to the video village then viewed in the Gratical. Preset, B&W or any one of your 16 presets saved in the Gratical Now this feature is pretty amazing – you can continue to record Log on the camera, as you display a LUT on the Gratical and just in order to be able to judge the image and exposure. Plus you can have a separate LUT output via the HDMI or HD-SDI out to an additional client monitor – without confusing them with the ungraded Log image. This feature can’t be underestimated. I find it’s easy to be “unexcited” about images shot in SLog2 or SLog 3 when shooting in the camera, simply because images don’t “pop” as much as they should if you compare them with their real-life counterpart. Selectable LUTs are also key … you can adjust the preview image to your needs. Some cameras have LUTs built in – however, on the C300 there is the built-in “View Assist” function which simply makes your preview image way more contrasty, but really, really ugly (and you can’t change that LUT) – plus you cannot even trust the waveforms and histogram for exposure anymore, because suddenly it only refers to the displayed image, not the C-Log image that is being recorded … Not on the Gratical though, the waveforms and histograms always refer to the recorded image, not the displayed image. This might sound minor, but it is actually quite key because you might end up exposing the image incorrectly if you trust the numbers there. Conclusion The Zacuto Gratical HD is an incredible viewfinder, certainly on par with the highest quality ones I have ever used – the problem with the other high end ones (Arri, Red, Sony …) is that they don’t work with all cameras. I plan to purchase the Gratical, which will live with the cameras I am using – now that I will be switching between FS7, C300, C100, A7s and Red Epic even more regularly on my shoots. Obviously it also makes sense if you have less cameras or just one, because the Gratical strikes me as a very future proof device. I can’t see many features missing from it at all and therefore I think it’s something that’s here to stay.Read more
