My 5DII will be on its way in about two months (been saving up for a long time!) and I've been itching to add a few short telephoto primes to my list.
How much different is 85mm from 100mm, versus 135mm from 100mm, in terms of FOV and DOF on a full frame camera? I don't see "too" much of a difference with my 70-200 on my 40D, but I can't judge prime lenses with the zoom.
I've always wanted to buy the Sigma 85mm and the Canon 135L, but lately I've been playing with my friend's 100L macro and I've been really impressed with its sharpness.
It would be ideal if I would get an 85mm and a 135L, but now since I'm liking the 100L also, I don't want them to really overlap each other. I'll be using the 100L for macro stuff also, but not that much.
