Hi all. I take a few hundreds pictures a month by just taking dogs pictures using my canon P&S (SD1000) but now I want a SLR. I want to know what you think should be the minimum requirement in the # of frame per second (FPS) for the SLR body to be able to capture, so I could comfortably keep shooting the photos of randomly & rapidly moving dogs at the field, then throw away bad frames. I've been doing it with my Canon P&S SD1000 and it doesn't work well at all. My SD1000 is impotent, and it sucks. More specifically I'm considering a Nikon D90 (4.5 FPS) or a D300 (6.5FPS). Does D90 shoot fast enough for my particular requirement? Thank you in advance for your opinions.
