Coolpix S630 is a digital SLR camera?
I need a digital SLR camera for a photography class I'm going to take the next Autumn and I have a Coolpix S630 and was wondering if that would work. THANKS GUYS!
No. As a general rule, if you can not change lenses, there is a reflex digital. Need full manual controls. Would not there, too. A quick reading of the Wikipedia article will explain better than me. http://en.wikipedia.org/wiki/Digital_single-lens_reflex_camera Only the first bit, to the Table of Contents
