[QUOTE="Bulldog, post: 33418, member: 7891"] Not to rain on anybody's parade, but I've had a Nikon 70 - 200mm f/2.8 VR lens for several years now and I am not too happy with it right now. This is my main high school and college football games lens and lately I've noticed that when used wide open (necessary for night games) my shots are not as sharp as they should be. I've tried fine tuning the autofocus on my D300, but that didn't make much difference. Just this morning I decided to do a lens sharpness test comparing this lens to my two other long lenses. A manual focus Nikon 300mm f/4.5 EDIF lens and a manual focus Tamron 400mm f/4 LDIF lens. The 300mm has a reputation for being a very sharp lens as well. Much to my surprise, the Tamron lens turned out to be the sharpest of the three. The 300mm came in second leaving the 70 - 200mm in last place. I am attaching a photo showing the results here. While I did enlarge the first two images so that they would be the same size as the third one in this photo (for easier comparison), that is not why the first two are not as sharp as the third one. I enlarged the third image 2x as well just to see what it would look like and it was still the sharpest of the three by far. Any comments?[ATTACH]5529._xfImport[/ATTACH] [/QUOTE]
