Hello, I figured this belonged here. I started forging into doing portraits alongside doing real estate stuff. I just bought the EF-S 10-18 for real estate work and now need something for portraits. I've been shooting crop (550D) alongside film. I've been shooting EOS digital and nikon film but now would like a lens that will cover both as I have EOS film cameras. I've been using a 135mm for 35mm film and a 50 on a crop for digital. The two options I am looking at are a 85 1.8 and a 100 f/2. The 85 would give me about 135 on crop but give me 85 on film. I already have that covered just about with the 50 on digital. The other option is the 100, that would give me 100 on film but about 160 on digital. Is this too long? Should I stick with the 85 or go with the 100? I've outgrown the 50 as of now, I do like the 135 but it's not compatible with my digital. Thanks.
