how does the sharpness compare to the 100-400L? anyone that has both of these lenses, could ya chime in!
TIA
Both the 17-40 and 100-400 are sharp lenses no matter what body they are connected to. That other thread you are reading is someone who is allegedly having some sort of problem. Who knows what.
I have both lenses and, as you can see, three different bodies I can attach them to. They perform the same no matter what body I use. I have also have a Drebel for a short time and a D60 and again, it made no difference what body I used, these lenses operated exactly the same.
Just because you read one or two complaints on a forum does not mean there is a problem. People operate their cameras in so many different ways that you cannot judge the sky is falling because of that.
Get the lens. You will not be unhappy.
