Let me (as if you have any choice) restate what in now a truism: THE CAMERA DOESN'T MATTER!
Five factors contribute to photography. In declining order of importance, they are:
#1- the PHOTOGRAPHER (ya gotta know what you're doing)
#2- LIGHT (if it's bad, everything else becomes more difficult)
#3- the SUBJECT (if ya got nothing good to shoot, quit now)
#4- the LENS (it's gotta be just good enough to do the job)
#5- the CAMERA (it's just a box upon which to hang a lens)
Photographers with vision and skill can and do take memorable shots with gear that's utter crap. This takes experience. (Good judgment comes from experience. Experience comes from making bad judgments. Ay yi yi.) Sometimes the correct light isn't there, so you do what you can. Read how
Harry Benson shot famous photos in low-to-terrible light. Sometimes the lens is all wrong; well, the best lens is the one you're using. And remember Sturgeon's Law: 95% of everything is crap (including photos from the best photographers).
