Fuji GX680
Fuji's GX680 is one of the only SLR cameras that captures negatives larger than 6x7cm. By pairing these large 6x8 negatives with impressive electronics with a range of movements more like a large format camera, the GX680 is an incredibly capable medium format camera. That is, if you can carry it.
The GX680 is most at home on a tripod in a studio. While you can handhold it, you'll more than likely end up with serious neckpain! Regardless of your application, the GX680 cameras offer top-of-the-line Fuji lens technology, metering capabilities, and automation that isn't found in most 120 cameras.
