So what is the alternative? Well, you could do what most of today's pros and some ambitious amateur photographers do and buy a "professional" 28-70mm zoom lens with a fixed f/2.8 aperture. These lenses are reasonably fast, quite sharp and well made. But they are heavy, bulky and very very expensive. For most people I believe there is a better alternative: the classic 50mm "normal" lens.

A great piece by the photographer Gary Voth on the wonders of shooting with a 50mm f/1.8 or f/2 – I only just started shooting with a prime about six months ago (there was one with my Olympus E-P1 that my Dad gave/loaned to me) and the difference is remarkable. 50mms are the epitome of "keep it simple". If you haven't got one, get one, and your photography will improve almost overnight.
