The Samyang 135mm f/2 is a great lens on any of the sony A7 series cameras when photographing things that are static, but i wanted to try and use the lens for fast moving subjects. So, without auto focus, I had to use zone focusing, but on the A7ll or the A7Rl, its not as hard as one would think.
I set the focus peaking level to high and the colour to yellow and by turning the zoom ring I could see a yellow band on the ground, so when a horse entered that area, all I had to do was trigger the shutter. Well it does take a little practice, but it can work very well and this method can create some great images at f/2.
Anyway, here are some samples of images that I did get right at Osberton Horse Trials. The panned shot is not razor sharp, but its passable.
So, if you are looking for a fast lens with nice reach at a very reasonable price, the Samyang 135mm f/2 is certainly worth a look and if you shoot Sony, the focus peaking and magnify really help.
