I am looking to pick up a used 5D classic to try full frame against my 40D. With the 5D3 being released, I know the used market (eBay) prices for the 5D classic and 5D2 are likely to drop as people upgrade.
I'm guessing this hasn't happened yet. I know some people are probably selling their old kit in order to pre-order the new stuff. But I'm guessing most people are waiting for the 5D3 to arrive and test it before selling their old gear.
So, how many months are people figuring before the prices drop and it's "safe" to pick up a 5D without it depreciating rapidly in price?
