Here's a Horseman 980, if you want some idea of what one looks like (lousy pic, I know). It's not lightweight (2.5kg as shown), so I tend to use my Speed Graphics more. But it does have a good range of movements, interchangeable lenses with their own cams, and a Graflok back so you can use a wide selection of backs in addition to 2x3 sheet film.
Nice to know that the Mamiya backs fit a Graflok, BTW, just wish I had known $99 earlier.
Tim,
Most, if not all that I've bought on ebay through the years need refoaming, I have sources for backs cheaply, less than $10 usually. If I'm going to refoam a back anyway, why spend the extra $$$? (I have a half dozen or so waiting for me to get to, probably once it starts getting dark earlier)
As to the front standard, it could probably just squeeze onto a 4x4 lensboard, with a little creativity.
Of course. I have a body for a rb67, it doesn't fire. I have both a Speed and a B&J 5x7 camera. The thought of a 90 or 65 with that quality piece of glass, built in shutter, with the coverage for 4x5.... nice.
