I am definately new to the camera hobby. I breed and raise tropical/salt fish for the trade and as a hobby. I am looking to get an DSLR camera to capture some nice shots of my fish and their unique coloration. Im sure it may seem easy to you that have been in the hobby but for me its a chore to get a few nice shots. My question is which of the DSLRs would be good for close range, motion(the fish are never still) shots to bring out the vibrant colors? I have talked to numerous people and most have suggested the Nikon D40 but I have read quite a few great reviews about the Canon DLSRs. The only other pictures that would be shot with the camera would be family and the occasional vacation. I will say I do enjoy learning new things and the photography hobby is definately new to me and from the looks of the posts through out the forum definately very vast. Thank you in advance for any knowledge you could pass my way.
