zooms are a good way to back up prime lenses too. When I go on a trip I usually take 3 identical bodies, and normally shoot with either 2 or 3 according to circumstances. Each body has the same film stock in - I never mix films - but of course a different lens, and as far as possible I don't change lenses while I'm shooting. Normally I like to shoot with primes for various reasons, but on a trip I always take a wide zoom and a long zoom - 28-80 and 80-200 - so everything is covered. If a body fails I have 2 more I can use; if a lens fails I have the focal length covered with another one. -- Cheers, Bob
