I have supplemented a 50 4.1 manual focus with a like new 50mm 1.8 auto focus for $50 today. Now I`m in the market for a 85 prime. In keeping with low cost, I seem to have found a 1.8 with perfect glass and mechanics, but cosmetically one of the worst lenses I have ever seen for $150. It looks like it did world war 11 three times. Auto focus 85 2.0, a 1/3 stop slower, lenses go for $250. I read a online report the 2.0 does not make anywhere as nice an image as the 1.8. Reviewer claims to have looked at 3 samples to draw this conclusion. 85 1.8 in reasonable condition seem to be double the money as the 2.0. Is it the 1/3 stop or is the 2.0 infact NOT such a hot lens. Anyone here have an opinion?
