I'm torn about upgrading my 50mm f/1.8 to the Sigma 50, or getting the Canon 85mm 1.8. The 50 1.8 is sharp, light, and cheap, but the bokeh on this thing is just hideous sometimes - see above. Maybe I'm just being picky, but I find it distracting. On the other hand, the 85mm 1.8 has way better bokeh, but the field of view of a 135mm lens on my 7D - way too long for street. I have the Sigma 30mm 1.4 which is my most-used street lens, but I'd like to have something on hand that gives a little more subject separation. Eh...
