Had been contemplating getting a Canon 7D when I saw a Yashica 635 Twin Lens Reflex camera on eBay. It is a double format camera that takes 120mm as well as 35mm film. It has a Yashikor 80mm f/3.5 lens with speeds 1-1/500. Comes with the original leather case too. Ordered it last night and expect to have it in hand in three days!
