Originally posted by ChooseAName I have a Pentax M 85/2 and it is my favorite lens. They are very rare though and run about $300 these days, I think. I second/third/fourth the suggestions for the Samyang/Rokinon/Bower 85/1.4. It is manual focus and it is huge but then again it's 85 mm and it's fast. It's pretty much exactly what you're looking for....great portrait focal length and affordable.
I do think 85/1.4 would be the best fit for what I'm looking for. Does the Samyang (et al.) 85/1.4 come up for sale used often? It's a great price point even brand new, but I'd be tempted to save that $$ and put it toward a used AF lens if I couldn't get a good deal on it.
The 70 or 77 would probably also work well, but if anyone has used the 70 and a 50 in particular - do you find them too similar?
I have that whole "I CAN spend X, but I was thinking maybe I'd spend more like Y, but well then my tax return is about to come and who needs a new deck anyway?" thing going on, lol. :P
