[QUOTE] How many lenses do people buy? - and how much do they spend on them?[/QUOTE] About 4-5 prime lenses for each system, and you don't want to know, even at used prices. [QUOTE] Katie has a city & guilds in photography, yet I can still count the total number of lenses we own, spread over 3 different brands, on the fingers of one hand.[/QUOTE] And your point is? [QUOTE] For 99% of use you need a short zoom and a long zoom. Whatever we buy will just need a single additional lens.[/QUOTE] Depends what you want from the camera, isn't it? The only camera I don't have a prime lens for is the digital compact, mainly because fitting one would be a tad difficult. For all the others, I have no zooms simply because you either can't get any for the system or because it would be a waste of a good camera - at the end of the day I bought my old Contax bodies so I could stick Zeiss primes on them.
