VIDEO: I used the Sony 85mm F1.8 lens on a A7 Sony camera to take portraits of numerous pets during a dog show in Paducah, Kentucky. In short, I was quite happy with the results.
The organizers didn’t allow photographers to use any flash or lighting equipment since it could scared the dogs and that was perfectly understandable. It turned out that Paducah’s convention center had really nice overhead lighting, so everything worked out great.
I kept the aperture settings wide open at 1.8 since I really wanted to see how it would perform with the natural overhead lighting.
Please bare in mind that neither my old A7 Sony full-frame or the 85mm lens had any kind of built in image stabilization. However, since the 1.8 lens is fast, hand held shots came out okay.
I tried to keep the shutter speed at around 1/ 170 to prevent camera shake. The formal calculation for the correct shutter speed is focal length 85mm x 2 = 170. The calculation worked out well but 1/500 shutter speed was even better.
I kept my ISO on Auto most of the time since I just wanted to talk with people and have some fun.
In conclusion, the Sony 85mm F1.8 performed beyond my expectations.
