Survey: What Focal Length Do You Use Most Often?

Or look at it this way:
You could replace a zoom with two primes and not miss a shot. In fact you'd have a faster lens at both ends AND probably get better optics. The Panasonic 14mm 2.5 is $214. The Olympus 45mm f/1.8 is $400. The Panasonic 14-50mm 2.8-3.5 is $821 - it's slower, more money, less macro.

What this tells me is the someone needs to put out a 200mm autofocus prime.
