That's for sure .. I definity didn't regret choosing the 7D over the 50D, even though the difference in price was really pushing the budget.
It's always cheaper to buy the one you want the first time, cos you will always wind up doing it eventually.
Cut out the in-between expenses, and it saves money.
I'm with the people who listed the Nikon 70-200mm f/2.8 VR II.
I'd really like to go to Leica - the cameras are bad enough, but the lenses are unbelievably expensive - it's so far out of reach I don't even dare lust for it
