I’ve had the Sony A7s for a few weeks now, and all I can say is that it’s a wonderful camera for shooting video (and a great one for stills). I have used lots of lenses on it, but there was one I really wanted to try. The Nikon 135mm f/2 DC, which is one of my favourite lenses and when the adapter for the a7s came, I went out for a short trip to shoot some video with it.
The whole video was shot with the 135mm. A few observations:
– This is a great lens for specials shots. At f/2, the depth of field is very narrow even at a longer distance, and of course the bokeh is spectacular. You can also create a more dreamy look by using the Defocus Control ring on the lens.
– You absolutely need a tripod, or at least a monopod. There is no image stabilisation on this old lens, and handheld shooting is not going to produce a good video.
– Using crop mode, you have a 200mm fast lens, which can be very useful when you need more reach.
– I have a chinese Commlite adapter for this lens.It seems well made and it works fine, but the tripod mount gets unscrewed all the time, so I have to be careful. The 135mm is a pretty heavy lens, so I am using an adapter with a tripod mount. Although the a7s has a strong metal mount, I don’t like testing its limits with heavy DSLR lenses. I am planning to get the Novoflex adapter with their collar ring at the future, but they are really expensive, so it will have to wait a while.
– Weather was terrible, rainy and misty, and I had to look after my equipment or shoot scenes quickly, so I didn’t have the time to use ND filters to keep a proper shutter speed. This lens takes 72mm filters, so normally I use my 77mm ones with a step ring.
Overall, I was very satisfied from this lens on the a7s. I know it’s a specialty lens, difficult to operate when wide open, but it has a very unique look which can produce stunning results.
