it's logical companion - for a two lens street kit - is the old, non-L, 85mm f/1.8. small, compact, affordable, fast, sharp, sharp, sharp & a very fine portrait lens. what's not to love.
The 35 & 85 does sound like a really good pair, I'm kinda intrigued actually. If the 24-70 wasn't prime-like optics @ 24/2.8, and damn near prime-like everywhere else, I'd sell it off and could be really happy with 35 & 85 I think!
I really want the 35 for night/street/travel. So it's definitely at the top of my lens wish list. Between the 85/1.8 and 100 f/2, I'd have to think about.
I think now I really need to just set the zoom to 35, walk around, and see how I feel about it before I do anything that's going to upset the boss!
