i get this question sometimes too. 🙂 the easy answer is: ALL OF THEM!
well… sort of. there are lots of folks out there that want to step-up their photography skills and feel as though the logical step is to purchase a digital SLR camera. while this is logical, the problem that most run into is that they feel that their photography will jump leaps and bounds once this happens. people get too caught up in the camera body and forget that the point is in the USE of it.
people at weddings ask me all the time “hey! what camera do you use? how many megapixels is that thing??”. the short answer is, IT DOESN’T MATTER! 🙂
