If Canon release a 5D 3, 35L II and a 24-70 II then I'm going to be seriously broke!
Do you really need to buy all of he new things that come out?
I convince myself that I need the things I want. It's a personal failing but one that I enjoy from time to time.
Exactly. Nobody ever says I'm happy with what I've got and I don't want any more.
It's the reason we all are where we are now, because of our drive to do better (even if that means buying better things)
