From Lenses: Primes or zooms: - Zooms are flexible: one lens covers many situations, and you don't miss shots changing lenses. - Primes (fixed focal length) are smaller, sharper for the money, and much faster. A 50mm f/1.8 gathers far more light than any kit zoom, at a low price. Most people end up with one or two zooms and one or two primes.
