When we were shown the Sony 600mm f4 G Master OSS, I was sort of shocked to see and hear that it was coming. My first thought would have been another zoom lens for sports photographers, but it would be unlike Sony to really just announce a zoom lens.
Instead, the Sony 600mm f4 G Master OSS is an option for photographers that pulls out all the stops. You're still going to need a monopod or tripod to shoot with it for long periods of time, but I'm going to admit that it isn't imperative. The lens works in combination with Sony's IBIS system to give the photographer a whole lot of image stabilization when photographing sports and birds alike. Then consider the weather sealing inside and the fact that this is the largest lens for a mirrorless camera system that we've seen thus far. And despite this, we completely see the value in it. . thephoblographer.com
