Reverse mount adapters for enlarging lenses

For macro photography

Quality enlarger lenses are one of the best options for macro and micro photography. Enlarging lenses are designed for high resolution and for flat-field focus, and this is a major advantage on using it for macro and micro photography. For higher magnification ratios and greater image quality, reverse mounted enlarging lenses on a bellows is the most usefull combination.
With the M39 Leica mount adapters, many enlarging lenses will have the same M39 Leica mount on both ends, making easier the use of the enlarging lenses on any direction. You can use it on a Nikon/Canon/other to M39 Leica mount adapter, as the one fitted on the bellows on the pictures above.
Adapters are now also available with M42 mount, T2 mount, Copal 0 front mount and Copal 1 front mount.
Schneider lenses were made with a few different barrels, so you should always check your lens front thread.

EL-Nikkor and EL-Nikkor N lenses – Since 1979, the “N” was added to the end of the lens name on catalogues and lens cases to denote the new type of lenses. The “N” (new) lenses are easy to identify by the new exterior design.
Rodenstock lenses with iluminated aperture display – For the lenses with this feature there is the need to block, with little pieces of black opaque masking tape, a small hole on the rear of the lens body. Otherwise light will pass through the aperture display into the lens barrel and into the camera.
