Input:
I have been using this lens for about 2 years with a 5d Mark ll. It is part of a collection of 6 high end lenses. I wanted to leave a message to anyone considering this lens. Buy it.  If you only have one good lens, this should be it. If you have some of the others like I do,  you will undoubtedly find this your most popular.  It seems to capture all types of photography well. If you are shooting streets and buildings,  the lens seems to wrap around the subject giving you a nice full frame. Portraits, general people shots, sports or landscapes, this lens can do all of this very well and is  deadly weapon for taking amazing shots.
Another reason I felt compelled to write this, I left this lens with my girlfriend for her to use with her 5D Mark ll, and I have been without it for a few months.  It's almost to the point where I don't even bother taking pictures. It is hard to go without, now I know how much I really love this lens.
