Special Features
The Mamiya M 140mm f/4.5 M/L-A is a Gauss-type lens that incorporates a floating-lens system.
The floating system moves elements within the lens back and forth to adjust the appropriate focusing
distance.
In close-up photography, the system ensures high resolution, not only in the central area of the frame,
but also at the periphery.
Exacting detail, not only at infinity, but also during life-size photography, is ensured when using the
Mamiya Auto Extension Tubes.
