At the moment I'm using a Fuji S5500 P&S, and having discovered that photography is mighty fun, I wanted to upgrade to a DSLR. The two ones I'm looking at are the Canon 400d (Rebel XTi) and the Nikon D70s, as their both in my price range of £500 thereabouts. I'm going into town tomorrow to try them out and see how they feel, but I want to know whats the difference between the two. I shoot mostly action photos (BMX, mountain bike, skateboard etc) and night time photos, because I love the way you can manipulate light. This is what I sorta understand/think at the moment Canon Better high ISO performance Cheaper lenses/more options for extra lenses More megapixels Dust removal system Nikon Better build quality (metal over plastic?) Better kit lens Larger in size Faster start up time I'm probably wrong with a few of those, and I'm sure that theres a million more points. Anyone want to offer any advice? Preferably with reasons, not just "Get Canon cos Nikon are shit" or "Get Nikon cos Canon users are fags" etc.
