The Mamiya Auto Bellows (NC401) is a precise macro accessory enabling continuous adjustment of the magnification ratio for extreme manual focus close-up photography.
Note: The Program and Shutter Priority modes are not available when using the Auto Bellows
A data cable transmits diaphragm information to the lens mount, enabling use of aperture priority AE mode or exposure confirmation in manual mode
The AF 80mm lens reverse ring allows reproduction at magnification greater than 1:1
The camera mount can be rotated 90° for simple selection of vertical/horizontal composition
The upper and lower rails separate and can be used in combination at a right angle, enabling the auto bellows to shift horizontally and enable reproduction of vertical images at the same magnification ratio
