July will be a very fun month for me with switching from Nikon to Canon (for reasons I've explained on here before so don't ask! ) and upgrading to a 5D. It's supposed to be a lot of camera so I'm sure there will be a learning curve, but I can't wait. Anyway, lens question. As I'm pretty much selling my soul for the 5D, I don't have money for an expensive lens immediately. Eventually I'd like to get the 24-70 L but for now I need something less than 400. I'm thinking about a tamron but it just seems stupid to put a tamron on a 5D. Does anyone know how that would perform? I could get another 50mm but I'm beginning to resent how much my current 50mm struggles to lock focus. Anyway, suggestions would be great! Thanks so much. Ps. In case anyone suggests it, I've considered getting a 30D and getting an L series, but I know I'd want to upgrade within a year and am just gonna go straight for the 5D and pray they don't announce it's successor this fall.
