Hello all,
Which lens would give me better image quality?
1. Canon 70-200mm mkII f/2.8L IS
2. Canon 100-400mm mkII f/4.5-5.6L
Thank you,
SNIP outdoor swim meet.>SNIP> I mostly shoot 70-200 at f2.8 and really love the sharpness of the main object as a swimmer and background blur but I can not get good background blur from 100-400mm due to aperture. Please advise.
I have all three lenses... 70-200 f/2.8 II, 100-400 f/4.5-5.6 II, and the 300 f/2.8 I.
Of these, the 300 f/2.8 definitely wins in the background blur contest. If that's what you're after and you've established that a 300mm focal length would be about right for your full-frame camera, then this is probably the lens for you.
I don't have any swimming shots, but here's a sample from the 300mm lens at f/2.8
You can find a larger version here:
This is the original version I of the lens... it's now on a version II (considerably more expensive) and I see Canon Rumors says Canon recently filed some patents on new big white lenses and there is another new design on a 300mm f/2.8 among them (so possibly there will be a version III on the way.)
I do love the 70-200 and the 100-400... and I use my 70-200 most of the time. But if you're at a swim meet and the 200mm end of the zoom range isn't enough... and the 100-400 is enough, but you're not getting the blur, then you've got to consider if the 300mm focal length solves the problem. As long as 300mm is a good focal length, then the optical quality and blur quality wont be a problem.
