I like the things this focal length allows on a full frame camera when used for street photography, but would like something a bit more portable than my 24-70L. Not that there's anything wrong with it, but sometimes I'm just going for a walk and I don't want to bring the red with me. So while the 24-70 will remain my workhorse when I'm serious - such as when I'm on some kind of trip in a faraway exotic land - I'm looking for something of a backup lens for everyday purposes. This means compact, sub-$500, and solid AF.
Just to be clear: I know the 35L is seven flavours of awesome, but it's way more than I'm willing to spend.
I've been looking at the Canon 35 f/2 but it seems it has basically the same AF as the 50 1.8, which I have found to be really lacking. The Sigma 35 1.4 is crop sensor only, so what are my other options and which would you recommend given my mission statement above?
