I am thinking of upgrading to a Canon 7D. Part of the reason is for the much better focusing system for action shots of wildlife.
I am also wondering if there will be any significant improvement in ISO performance from the 50D, or would a better option would be to invest in glass.
Thank you for any advice.
Ah yes. I consider the 50D to 7D one of those tough decisions. Yes, the 7D overall probably is better, but the 50D is already so good it will be very hard to justify the upgrade. No signficant improvement in ISO I'd say, just look at Bryan Carnathan's website. If you're 50D is not that old, I personally wouldn't make the move. The only improvement I'd make from 50D would be to either FF or a newer APS-C camera that has not come out yet. That's just what I would do. Get some good glass.
