Hello everyone. Would appreciate some thoughts and advice on this. I have been using my 70-200f4 non IS for my telephoto and for some macro with tubes. I recently acquired a 100-400 and also a 100 macro. The 70-200 has been a great lens for me but I don't see me getting much use out of it with the new acquisitions.
I feel my lineup is covered pretty well on the wide end and the long end with the 100-400 in good light. I haven't used the 100 macro (which is f2.8 also) indoors a whole lot but looks to be ok if you don't need fast focus. The 17-55 works pretty well indoors for me as I don't need to stop action that much. The low light shots I take are more stationary. For more length in low light, I was thinking of trading the 70-200f4 for the 200 F2.8 prime.
So, I guess my question is two pronged.
A. Does anyone else use the 70-200f4 with other lenses like this in the mix? What for?
B. How big an advantage will the extra stop [from f4 to f 2.8] give me at the 200mm focal length? I haven't shot a lot of low light stuff at this focal length so advice here is really needed. I am thinking of shots like in a school gym at concerts or graduations. Possible wildlife at dusk/dawn when the 100-400 would struggle. Of course there is no IS on this lens so that doesn't help. Would it be hard to handhold? The 70-200 f2.8IS would be ideal but that is too cost prohibitive for me right now.
Thanks in advance for any input.
