Problem is that you are lumping all Canon L lenses into a certain class. Like everything, some are better than others. Some non-L's are better than older L's, etc. The comparison you showed does not suprise me with the 35L. The 35L I think is one of Canon's "weaker" L primes, whereas the 24L, 85L, 135L, and 200L are very strong. (35L and 50L I don't particularly care for). To answer your question regarding the 85L vs. 85 f/1.8 at let's say, f/2: Yes, I think the 85L II does look better overall. With the 50L and 50 f/1.4, I could never tell the difference in anything between these two lenses at f/2.
Thanks, your post really helped solidify what I should be thinking in terms of this order we're going to place.
I think the 85L is a must, the Sigma 35 is a no brainer (at least until reviews of Canon's replacement for the 35L), and the 50mm length can be covered by the 1.4 for awhile.
Would you guys suggest anything else to think about adding to the bill? I know there is an army of people supporting the 70-200 mkII, but I already love the look and personality of primes, and I just don't think I'd get as much enjoyment out of a zoom lens.
I think where you get an army of people supporting one of the 70-200L f/2.8 IS v2 is that it's quite sharp, fast, great IS, and very versatile and covers a fantastic short to mid telephoto for wedding/event type photography. Sure, you can have an 85mm, 100mm, 135mm, 200mm prime lenses, but when there is something happening right now, right this second, being able to go from 200mm down to 70mm quickly to get in on the action can literally let you get a shot you wouldn't otherwise.
That said, primes are awesome, and I'm going to (eventually) be getting some more of them. The one I'm lusting over is the 200L f/2, but that'll happen when I win the lotto. But if your style is completely primes, and you have a 2nd body so you can have a wider lens on one, and a longer lens on the other, with today's high megapixel cameras you can generally crop a decent amount and still get a fabulous print if you need to.
