Hi guys, Currently I have a 40D, I want to shoot video (got contact to shoot a music video recently ). I'm undecided between a 7d and the 5d. The reason is cost vs. quality. If I go for FF, I'll only be able to use a 100mm macro, 70-200mm f4L, 50mm 1.8. If I stick with a crop sensor I'll be able to use the tamron 17-50mm and 10-22mm with the others. So basically, I'll have no short focal lengths for the 5D, which makes me think I'll need something to cover the tamron's range (17-50mm). I was looking at the 17-40mm f4L to replace it. This all adds up to a huge price increase (which means I'm gonna be poor for the forseeable future). Here's some of my pros and cons for a 5D purchase: 5D pros: Better image quality Better vid quality (but I'm not 100% sure, heard about firmware upgrades to fix some of the 5D issues, advice on this?) No need to upgrade for years to come The video project would/should pay for the camera + lens It's a fucking 5D!! 5D cons: Price Need to buy EF lenses I've been stuck in a rut lately and I'd be pissed if I dropped a lot of cash on something that I won't appreciate/use enough. I'm still very much an amateur photographer. The big thing for me is that if I get the 7D, it's price will drop, resale value will go down and I'll end up spending more in the long run. I don't want to sell the 40D. What would you do if you were in my position?
