Hey guys, I have a question for everyone. I have a canon 40D and I've been kicking around an upgrade. I have a full replacement plan from bestbuy, so I could probably take it in and get a brand new 50D at no cost. So my question is, should I just turn around and sell it and get a 5dmk2 or a 7D? Reason why Im asking is I might have a pretty good freelance gig with a car mag and Im not sure my 40D will cut it... So whats everyones opinions? Also do you guys have any lens and lighting recommendations? Right now I'm working with a 480ex and renting lights from time to time and I'm looking to buy something like maybe a 50ex2 and a wireless transmitter or something. As far as lenses go I only have the 28-135 it came with and a 17-40L. So if anyone could offer some friendly advise and tips that would be great! Thanks!
