Quote:Most AF lenses focus wide open - so I was referring to Rover's "If only it hadn't been MF..."And 400mm f4/ 500mm f4/5.6, 600mm f4/5.6 lenses and so on... The AF can cope with thin DOF. For MF, you need a god focussing screen.
​Chances are very high that it would miss focus a lot of times, even if it's only a small movement of the photographer or the model or both. On the other side, there are 200/2 lenses which are similar in that aspect and - to make things worse - heavier at the same time.
