I think I'm in trouble with my new 70-200 2.8 IS. After seeing such great images from others with this lens I'm very disappointed
On my 20D It seems to be relatively crisp out to about 15 or 20 feet and then the IQ becomes very poor. Images just seem to be OOF. Is this symptomatic of a particular problem anyone is familiar with?
I was hoping that it was user error, but I've shot over 100 images, (all in RAW format) just trying to get something I consider sharp, or comparable to other images I've seen from this lens, and I can't get there. Could it somehow be related to the body?
I'm a designer with competent post skills so that is not the problem.
I have not read of even one person on this forum having a problem with this lens. I feel bad about asking for an exchange on this lens and I have to do it today or send it to Canon to look at.
The following is a sample image.
Any help or suggestions would be greatly appreciated. Thanks.
Mike
