I had 24 hours to play with the Sony 100-400mm f/4.5-5.6 OSS GM. The main reason I rented it was an ISS pass in front of the moon. With my camera’s 11 fps burst rate, I managed to get 7 shots. Here’s one of them:
It would have been a waste to shoot just an ISS passing, so I got up the next morning and went to one of Bucharest’s parks. Unfortunately, the city is very foggy these days. Luckily the sun came through that morning.
As for the lens itself, it’s safe to say it looks a bit ridiculous on my a6300. Image quality is great, autofocus is snappy and the range is great for bird photography, especially on an APS-C camera. As an owner of a camera without IBIS, OSS has proven to be fantastic.
Despite all the positives, size and weight remain an issue. A better fit would be the 70-350mm f/4.5-6.3 G OSS. I hope to test it soon.
