Just further to my last post, since I was a bit rushed...
My current cameras (beyond the Olympus C5050-Z) are:
Canon 50D (actually my dad's but I use it a fair bit as well) with a number of lenses, including a Canon 70-200 2.8 L, a Tokina 11-16 2.8 (I think it was), and a few others.
Minolta SRT-101 (yep, film...) with a number of lenses including a 50mm (f2.8), 58mm (f2.8), 24mm (f2.8), a 200mm (f4 for this one I think), a 400mm (F4 I think), and another two lenses that I can't remember. Also got a converter ring to allow all of our Minolta lenses to be used on the Canon 50D (and soon the 7D), including a focus confirm system.
Currently used for B&W photography.
Minolta XD-7 (yep, another film camera), with the same as above (not really used, to be used for yet more B&W photography).
Plus a few other old cameras scattered around the house that get the odd use
So yeah, bit of a collection, but great fun, especially the film.
