I currently have an EF-S 18-55, EF 28-135, EF 24-105 f4L IS and 70-200 f4L (non-IS).
I'm debating what my next lens will be. I've heard people the me to get a prime lens, by why? One I've been looking at reviews on is the Canon 100mm f2.8L IS Macro. What makes a prime a better choice than, say, a 24-105 "L" zoom that would be capable of the same FL? Is there really that much IQ difference?
I would say get a 1.8 or faster in a focal length you use most often; in a macro if that is important.
