This is a question men't for the more serious on here. My friend and I were talking about possible upgrades, and while we both love our Nikon's we have noticed that almost every photographer we follow and love shoots Canon. I haven't noticed a huge difference in image quality between Nikon and Canon photo's, I'm just really curious as to why the prevalence of Canon amongst professionals? I'm a long ways off from any upgrade, but my friend is looking to go to full frame in the next few months and we are really torn on sticking with Nikon or switching to find out what we are possibly missing out on? I don't want this to be a Ford v. Chevy conversation, just looking for the reasons people have already gone one way or another.
Thanks for any input!
