I'm helping out an organization that does head shots and team shots for local kids sports teams. I want desperately to be comfortable using their gear. Problem is, they use Nikon
. I used to have the exact same set-up as they did before switching back to Canon. They have the D80, the 18-135 kit lens, and the SB800 with the Polaris light meter. My husband currently is out of work and we're going to be hurting pretty soon if he doesn't find something. I am currently accepting small amounts of money under the table assisting their photographers. I know it will become the dry season very soon as schools are going to be out. Ok, here's the long-winded question... do I sell off all my gear (I'd get at least $3,000 for it all) and purchase, dare I say it, what they have? It would cost me about $1,500 for the D80, 18-135, sb800 and meter. I could put the extra dough toward bills and get good at re-learning for future shoots.
Of course, they could switch all their gear tomorrow... so, is this a bad idea? I know no one here would advise selling Canon for Nikon. And if it were any other day, I wouldn't even consider going back. But perhaps it's worth it since we're broke and it could help a little with my new job?
The subjects you will be shooting don't care what camera you will be using so why should they.
