Title: Simply the best in this focal length range
Review: I bought this lens to replace the Ef-s 17-85mm on my 20D. That lens is nice especially with the IS, but too darn slow. The 24-70 is an L series lens, which according to Canon means "Luxury". If being sharp, contrasty and fast means "luxury" then by all means this is just that. I have taken about 400 pics since buying this lens and am just amazed with it. It is heavy, bulky and expensive, but if you want or need the best, this is it.
Is the review positive or negative?
