Hi folks. I own 3 Canon lenses, and mainly use the 24-70 f2.8 L USM along with the 70-200 f2.8 L USM. I also have a 10-22 E-FS but don't use that as much. I've been reading how many people on this forum say that primes are better and sharper for various reasons. I've been thinking for a while now about getting a Canon 50mm f1.8 II USM or maybe even the 85mm version. The question is....If I'm already using "L" series glass for most of my photography will i gain much in getting the prime lens? I know I'll gain a stop thamnks to the aperture, but is the quality in the prime noticeably better than an "L" series zoom??
