Hey Unix. I don't want to change gears on this thread but can you summarize your opinion of that 85mm f/1.8? I just read about a dozen reviews and every single one of them praises that lens and it is always being referred to as an excellent, or near-perfect portrait lens. Do you agree with all that?
I want one

it's a little too long for my preference. on a 1.6x crop, you'll be standing a good distance away. if you want the 'headshot' it's not so bad, but if you want waist up, 3/4 or full body shot, the 50mm focal range is the easier way to go. unless you have lots of room and dont mind stepping back a few extra steps.
however, it came in pretty handy when shooting performances or random shots of people out at the mall or even sports like basketball/volleyball.
as for performance, the build is solid and the USM is amazing! after you have a taste of the AF/USM, you'll know why people say the 50/1.8 is noisy and that it hunts a bit. my 85/1.8 has never hunted except when trynig to focus on things too close or when focusing into a dark background in low light. it's a world of difference IMO. if you feel the 70 is not long enough for you for portraits, the 85/1.8 will likely give you what you want. (give or take a couple steps)
