What's your opinion on the big 1.4/1.2 prime lenses, are they worth it? I've been photographing for a few years now, and have a nifty fifty and a 135/4 vintage (full frame). Although i'm happy with the results, i'm curious if i'm missing something and just don't know it. I'm doing portraits and landscape, and i try to stay away from "bokegraphy", so i stop down a bit. If i'd buy one, it would be a 50mm, maybe Milvus, or the Canon 1.2. I'd love to hear any recommendations, what to look for, what to stay away from...
