I'm considering buying reasonably inexpensive Russian-made tilt and shift adapters that allow for Kiev/Pentacon Medium Format lenses to be used on Nikon/Canon 35mm and digital bodies. The tilt and shift adapters each cost around $80-100, and Pentacon and Kiev lenses in the 45mm to 80mm range can all be gotten for prices under $100. So this seems like a pretty inexpensive means of getting tilt and shift capability for my Nikons. And the lenses can probably be sold for similar prices as they can be bought for, being older, mechanically simple medium format items. Has anyone used any of these Russian tilt/shift adapters? I've heard that the Kiev and Pentacon lenses are pretty decent for the price. Any feedback or experiences doing this would be appreciated.
