I don't even care to count the times I've heard it anymore:
"You've got to have a big, professional looking camera in order to be taken seriously as a pro".
One guy even went as far as to state that a big camera, preferably one with a grip attached, no matter if you need it or not, serves to "transfix" (sic!) the subject. Which, I guess, has no option left but to obey to the photographer's demands. Oh well...
It's certain I'll return to this matter in future blog installments; for now, let me just state my opinion that the current fascination with "full frame" cameras (as they are erroneously and quite arrogantly known) is just a current fad and marketing plot.
For starters, here are a few great articles from a very talented photographer, which also happens to be a woman.
The first one discusses the "Big Camera" syndrome itself.
Then, there is a couple of articles comparing full frame cameras with the popular micro four thirds system, from the standpoint of a working pro photographer. You can find the first part here, and the sequel here.
Enjoy and stay tuned for more on this (and many other matters) on the blog!
