Sony has announced two new lenses for their full-frame E-mount cameras: a premium “bokehlicious” 100mm f/2.8 G Master lens, and a compact 85mm f/1.8. Both Sony FE Prime lenses are available for pre-order and will ship in March. Sony 100mm f/2.8 STF G Master lens – made for “bokeh lovers” The first of the new Sony optics is the 100mm f/2.8 STF G Master OSS lens. The name of this mid-telephoto prime lens already proclaims it belongs to Sony’s premium G Master line, but what’s special about this glass is the apodization element marketed as “STF – smooth transition focus”. It is basically a circular gradient ND filter which helps create exceptionally smooth bokeh but does not affect the subject in sharp focus, creating a much smoother transition between areas in and out of focus. This filter element, however, reduces the amount of light coming in through the lens, and results in a T-stop of T5.6 when wide open at f/2.8. Sony claims that despite having this filter inside the lens, vignetting is kept to a complete minimum. Apodization element inside of Sony FE 100mm lens.

There is also a macro ring switch for changing focusing distance, allowing up to 0,25x close-up shooting. Other features of the Sony 100mm f/2.8 GM lens include: ED and aspherical elements to reduce aberrations Nano AR Coating to limit flare and ghosting Fast and silent focusing through an SSM motor Optical StadyShot image stabilization Dust and moisture resistance Programmable focus-hold button Physical aperture ring for manual control Sony FE 85mm f/1.8 lens Sony’s second announcement is a cheaper full-frame E-mount lens. It is the Sony FE 85mm f/1.8 lens, a much more compact product than the GM 100mm lens (700 grams vs 371 grams). This piece of glass sports a 9-blade circular aperture, as well as an ED element to minimize aberrations. It features a programmable focus-hold button too, but has no stabilization. It extends Sony’s affordable full-frame primes line along with the existing FE 28mm f/2 and FE 50mm f/1.8. Bokeh comparison 100mm (left) and 85mm (right).

The lenses you choose to shoot with are just as important as the camera, as they help build the composition and look of your shots. But what lenses should you choose? Today we look at some great zoom glass for filming on a budget. Note: The lenses I mention are ones that I would recommend from experience, as well as what we’ve reported on here at cinema5D. There will never be a right or wrong choice of what kit you use! Shooting Micro Four Thirds and APS-C Focal lengths of lenses on MFT or APS-C cameras get a bit confusing sometimes. A 17-50mm isn’t actually a 17-50mm. The focal lengths are multiplied by the camera manufacturers ‘crop factor’, which on Canon APS-C cameras is 1.6x and on MFT sensors like on the GH4 is 2x. That wide angle you were looking for with the 17-50mm zoom? Nope. It’s actually around 27-80mm. While in the topic of wide angles, capturing such perspectives is often difficult without compromising distortion, a slower aperture or price, but still top of the list is the Tokina 11-16mm f/2.8. It has noticeable barrel distortion at the wide end, but after zooming in slightly, this is somewhat reduced. The wide aperture of f/2.8 is ideal for low light situations, but does get soft towards the edges of the image. The equivalent focal lengths are around 17-25mm (APS-C) and 22-38mm (MFT). One of the first lenses I used with a Canon 60D quite a few years ago was the Tamron 17-50mm f/2.8. It has a fixed aperture of f/2.8 and better optical quality than the Canon 18-55mm f/3.5 – 5.6 kit lens you get in the box. It also has ‘Vibration Control’ (VC), Tamron-talk for image stabilization, critical for steady pictures for video. Equivalent focal lengths are 27-80mm (APS-C) and 34-100mm (MFT). For shallow depth of field, both the Sigma 18-35mm f/1.8 and Sigma 50-100mm f/1.8 hit top marks. Being a fast zoom lens, the wider aperture gives using a smaller sensor camera much more flexibility with light. These lenses are pricier, but you pay for the Art quality of the Sigma lenses and that wider aperture which isn’t seen in any other zoom lenses. A combo of these two is a great kit with equivalent focal lengths of 28-56mm (APS-C) and 36-70mm (MFT) for the 18-35mm, and 80-160mm (APS-C), 100-200mm (MFT) for the 50-100mm. Another option if you don’t use lens adapters and shoot on an A7S II or E-mount camera is the Sony 16-50mm f/3.5-5.6 , great for gimbal work with its optical stabilization and wide angle. I’ve used it a couple of times on the a7S for this specific application because it is light and has auto focus functionality when it’s directly mounted to the camera. If you’re a GH4 user, there are many great lenses from Panasonic available that keep the camera and lens combo compact. Two I can highly recommend is the Panasonic Lumix 12-35mm f/2.8 and Panasonic Lumix 35-100mm f/2.8 (the 24-70mm and 70-200mm full frame focal length equivalent). Both have O.I.S built into the lens to keep images steady, and the constant wide aperture is needed for those shallow depth of field shots on this small sensor. Of course, it’s still possible to use some of these lenses on larger sensor (S35 and full frame) cameras that have a sensor crop feature, like the A7S II, FS5 and LS300, so their uses aren’t limited if you step up to a different camera. Shooting Super 35 and Full Frame Here’s where there is a step up in pricing, but also in optical quality. In some cases, if you’re looking at buying your first camera that is APS-C or S35, getting a full frame zoom lens will give you better quality images than the APS-C equivalent, but it will cost you more. At the wide angle end, prices vary for lenses depending on their aperture. For example the Canon EF 16-35mm f/4L comes in at $999.00 compared to $1499.00 for the non-IS 16-35 f/2.8L II model. The latest version of that lens will set you back well over $2000. For a wide angle lens under $1000, the Tokina 16-28mm f/2.8 is the next best thing but lacks image stabilization. I haven’t personally used this lens, but at $689 it’s half the price of its competitors. If image stabilization is key for you (for Steadicam and gimbal work for example), the Tamron 15-30mm f/2.8 lens coming in at just about $1000. Full frame means brighter images with a shallower depth of field. Saying that, having the widest aperture possible is not always the best option in terms of sharpness. The Canon 24-105mm f/4L is still a very popular lens for filming, with many people I know using it on both DSLR, mirrorless and video cameras like the C1 Mark II, C300 Mark II and FS5. For $100.00 less, an alternative is the Sigma 24-105mm f/4 Art lens. I haven’t tried this out but if the build and quality of the Art range is to go by, its worth a try. If your disposition is a wider aperture over focal length, the 24-70mm f/2.8 is your go-to choice. Don’t feel like you need to buy into the Canon ‘red ring’ club either, as there are many other lenses from Sigma and Tamron that are considerably cheaper than the Canon version. I personally use the Tamron 24-70mm f/2.8 and I love it. It’s my go-to standard lens and is on the camera all the time. It stands up to the Canon in terms of optical quality and value for money, but I have had some compatibility issues using this lens with an EF – E mount Metabones adapter. Your choice of lenses has a great deal to do with what kind of things you’ll be filming. For shooting events, wildlife or sports (particularly outdoors), the mid range telephoto Canon EF 70-300mm f/4.5-5.6 is a good choice. It does have a variable aperture (meaning as you zoom in, the aperture will stop down), but it is sharp at f/5.6. The extra focal length taking it up to 300mm is ideal if you like to steer clear from your subjects. It also features 2 mode image stabilization, which is definitely needed at the telephoto end. Again, if you need the option of a wider fixed-aperture telephoto, there are models out there from Canon, Sigma, Tamron and Sony with varying features and pricing. For telephoto lenses, optical stabilization is a must unless you have the option of in-body image stabilization, or IBIS, or you risk shaky shots on the long end. The Tamron and Sigma models are both less expensive than the Canon and Sony counterparts, and like the 24-70mm lens options, the optical quality is very good. On the longer end with a fixed aperture I recommend the Sigma 70-200mm f/2.8. If you’re shooting with a Sony E-mount camera like an A7S, the Sony FE PZ 28-135mm f/4 G OSS lens is a great choice and has come down in price significantly. Understandably, it’s more than double the price of the other lenses mentioned in this post, but it’s a very good all-round ENG-style lens. It features a manual and servo zoom (although this is somewhat slow to respond), manual and auto focusing, and is native E-mount so there is no need for an adapter. If you’re not interested in buying, what are your rental options? Being flexible is part of being a filmmaker, as you never know what the next shoot will demand of you. If you’re in this boat, renting rather than purchasing lenses is an economical choice, and many of the above ‘photo’ lenses are widely available from rental houses across the world. You can rent the Canon 24-105mm f/4 IS II from lensrentals.com for $41 for 4 days, for example. Depending on the production budget, you could of course stretch all the way up to an Angenieux. But on the theme of budget lenses, you’re more likely to have the option of the new Zeiss Lightweight Zoom 21-100mm T2.9 – 3.9, which can be hired for $332.00 for 4 days. The superior optics of this lens surpasses that of photo lenses, and you can check out our hands on with it at IBC 2016 here, and Nino Leitner’s documentary film and blog post about using the lens here. Of course, this is a PL and E-mount lens, but what are your options if you’re a Canon shooter? A good budget-oriented option for renting higher-end EF lenses is the Canon CN-E Compact-Servo 18-80mm T4.4 L IS EF, which has cinema grade optics, for $168.00 for 4 days. But as I mentioned above, there are a vast range of L series lenses, including the 70-200mm f/2.8L IS II, that can be rented for a mere $63.00 for 4 days. Final Thoughts Hopefully you’ve found this post informative and helps narrow down your choice of zoom lenses for filming. There are so many to choose from out there, that ultimately your budget and what you shoot will determine the best decision. I’d urge anyone looking at purchasing a lens to check it out in person first; whether that is visiting your local camera store or renting one for a few days to see how it feels. A lens can look fantastic on paper, but feel completely different when you shoot with it. At the end of the day, it’s a personal choice, so never let anyone put you down for choosing the lens you want!Read more
