Can you tell me what these guys are using for their photo assignments? I know Rockwell takes out his best gear for photo assignments and never his ever all time favorite Nikon D40. Btw, he called this camera one of Nikon's crappiest read here -->
Nikon 50mm f/1.4 AF-S A guy who is in love with Nikon, but eventually buys Canon and then later on claims that all digital cameras are crap compared to film.
Anyway to the topic.
For me. The indian and the pana, both matters. Although I'd put more weight on the indian, but better equipment is always welcome. Check out the PROs when they do paid assignments. Do you see them use point and shoot cameras? (ok naa gyud mo comment ani, yes naa sad pro mo gamit ug point and shoot, but majority, nope) I say this, because I'm a digital point and shoot user. And its very limiting and frustrating to use a slow camera with very inferior lens and a crappy flash. I get good photos alright, but not without going through a lot (carrying a tripod with you all the time to avoid camera shake in situations where a dslr can easily be handheld). And there are times when you just can't get what you want because your camera limits you. (example. you can't bounce your flash up the ceiling with your point and shoot camera, so I go slow synch flash with camera on a tripod and pleading to all my subjects to please stay still). Then there's good bokehlicious... no way your point and shoot bokeh can compete with a SLR bokeh. (yes yes.. there are times... like 1 in every x something) and finally, speed. Yes, there are really good photos that can only be done with a fast camera --> body and lens. Sports photography example.
If you shoot for yourself, then by all means, use any camera you like. It's your art, your style and nobody's gonna sue you if you fail. There are hobby photogs that even use iphone as their main camera and still make really good photos and even do macro photography with a simple DIY macro lens using a cd players lens.
But when it comes to shooting for a client, you better be sure to give what the client expects and not get limited by your "pana". Or you are one dead indian.
That's where the better PANA comes in. PRO photographers want to factor out the hardware limitation and the possibility that their equipment can't catch up to what they want or worst, fail on them. With the hardware limitation out of the way, photographers can then focus on the task in hand and that is being a photographer.
