Canham wood field cameras are made black walnut and T-6 aircraft black anodized aluminum. Elegantly handcrafted, easy to use and very versatile. All specs are the same for both the 4x5 and the 5x7. The 4x5/5x7 field camera has a modular design. A 5x7 or a 4x5 back, or the entire rear standard bellows back assembly can be removed and replaced with a 4x10 rear standard bellows back assembly and used with the camera.
