We have recently upgraded our camera back, and have a Canon 50D for sale. It is about 2 years old, and is a really solid, semi pro stills camera. It will come back only with the grip, second battery, charger, box, and cables. There are few light scratches on the top LCD, but other than that, it's in great shape. Specs are 15 megapixel, 6.3fps and a 9 point autofocus. It has more settings and flexibility than most folks would ever need.
They are still about £550 new, and the grip plus extra battery is £200 worth, so make us an offer!
