Canon 70-200 or 100-400
Feb 11, 2014


I'm considering both of these lenses.

I've read that the 100-400mm is slow to focus and the autofocus stops working at f/8 or lower - is that correct??

I'll be using them for general purpose events, concert photography - indoor and outdoors and some sports events - again indoors and outdoors.   My concern is the 100-400 won't be able to capture as quick due to it being f/4.5 - f/5.6 but it does give me the reach of mid-telephoto.

The 70-200mm shouldn't have a light issue being f/2.8 but I'm concerned about the reach.

Ideas / anybody?
