Gear choice : Canon EF 200mm f/2.0 L IS vs Canon EF 300mm f/2.8 L IS II

[HDNitehawk]

In Bryan's review of the 200mm it compared favorably to the old version of the 300mm. How the 200mm compares with the new 300mm II is a little tougher to figure out since the 300mm is so new. There might be slight improvement with the new 300mm.

Your question though was there a huge difference in IQ. The answer is going to be no. All three lenses hold the top three or four spots in IQ. Any difference is going to be minor not huge.

I would think the 300mm would be a little long for the type of work you are talking about. You have first hand experience and know if it is right or not. IMO just pick the lens that is the best focal length, any other issue doesn't matter with these lenses.
