I arranged a temporary trade this evening. I lent my EF 35mm F/2 (my favorite lens, I shoot with it extensively) to a friend of mine, and he in turn let be borrow his EF 85mm F/1.8 portrait lens. This is a very mutually beneficial swap. If he is sufficiently pleased the 35mm F/2, he'll buy it instead of it's F/1.4L cousin (which is about $1000 more expensive.) Other than EF 70-200 F/4L IS, the 85/1.8 is the lens I am most likely to buy next. It takes me a while to "get" a lens. Much more time than 5-10 minutes in a shop, or even an afternoon's rental (not that there is a lens rental place around here.) I'm looking forward to spending the next couple weeks working with the 85mm.
This is why I love the 35mm F/2:
I have shot with the 85/1.8 before, but none of the results are remarkable enough to post here. Hopefully there will be some soon.
