The weight of the one makes it a nice travel body like Anthony says. So to lean a little off topic of cameras to gear in general. It's funny that amateurs can't deduct the price and don't make money with the gear but they can buy what they'd like. Professionals gear up for jobs and don't always have what they'd prefer for vacations. Take me. I have the 70-200- f2.8. Fine for work. Do I want to take it to Europe nope. But it's hard to find something decent that's a step down in various qualities and to justify it's price for two weeks a year. You don't want to shoot with a junky lens but the size of things can be an issue. Have fun all Steve
