Buying a DSLR system
Giles makes a reasonable point, but I'd like to put in my perspective. I have been a Pentax user for years and had a range of lenses from 28mm to 600mm. I was always put off going digital because of the idea of scrapping those lenses and buying into a whole new system.
I eventually bought a Pentax DSLR and found that I could use all of my old lenses - albeit they're manual focus.
Many digital lenses these days are built specifically to suit sensor sizes which are not as big as a full 35mm film frame (full size sensors are currently restricted to pro cameras). One of these days I imagine most DSLRs will have full frame sensors, which will entail buying new lenses for people who have built up a kit of the current digital lenses.
Funnily enough, if that happens, my old lenses will still be usable.
You can get plenty of full frame compatible digital lenses, but they do cost more - they might just be a better investment in the long run.
