Kipon Baveyes Ultra 0.7x Mamiya 645 to E-Mount Pro Lock

Description DescriptionFootage The Kipon Bavayes 0.7X medium format focal reducer with Pro Lock for cameras with an e-mount, let you use Mamiya 645 medium format lenses and let you see the full angle of view as if you shoot on a Medium Format camera. The Kipon focal reducers reduces the Image circle of a medium format lens by 0.7X so it fits a large format sensor (36X24), but you can use this focal reducer also on cameras with a smaller sensor, and it will still reduce the crop by an amount of 0.7X. Due to the Pro lock, which is basically a PL mount (positive lock), you asure an extreme sturdy connection with your camera, so no more lens wiggle, especially with focus motors, and mounting a lens is a breeze, because you dont need to twist the lens, just the lock on the adapter! The focal reducer can also be called a ‘speedbooster’  since it adds one stop of light to the transmission of your lens. The focal reducer was designed together with the German Optics research institution IB/E. We have written a lengthy article about the use of Medium format lenses in conjunction with this focal reducer, so if you want to go in depth read our article here.
