Leica Macro Adaptor M for 90mm F4 Macro lens

Macro Adaptor M for 90mm F4 Macro lens 
Product Description:
The Leica Macro-Adapter M is specifically designed for and attaches quickly and easily to the
Leica Macro-Elmar M 90 mm f/4 lens so it can be used for close-up photography.

Key Features:
It acts as an extension tube, permitting shots at distances from 0.77 to 0.5 meters.
This distance range yields magnifications from 1:6.7 to 1:3, meaning that objects ranging in
size from 161x241 mm down to 72x108 mm can fill the entire 24x36 mm format.
The two elements comprising the Leica Macro-Adapter M ensure automatic parallax compensation
for the Leica M's viewfinder, and provide an integrated mechanism the transmits the distance
setting, ensuring correct positioning of the viewfinder frame.
