Mamiya Auto Bellows NC401 For Mamiya 645AF Series & Phase One Description


This high-precision macro accessory enables continuous adjustment of magnification ratio for precision manual focusing. A data cable transmits diaphragm information to the lens mount, permitting the use of aperture priority AE mode or exposure confirmation in manual mode. The AF 80mm lens reverse ring enables reproduction at magnifications greater than 1:1 with very little aberration over a range of 0.75 to 2.20 times with the AF 80mm f/2.8 lens. The camera mount can be rotated 90 degrees (for simple selection of vertical/horizontal composition.) The upper and lower rails are used in combination at a right angle, thus enabling the auto bellows to shift horizontally and enable reproduction of vertical images at the same magnification ratio.
