           Regretfully Retina House ceased business and is no longer
connected to this circuit - so those
           adaptors are true collectors' items.

           According to Ryochi - he had a certified machining company for
Olympus - make those adaptors.

           The Kern themselves are also collectors' stuff - ALPA went out of
business in the mid 80s.

The lens is a Kern Macro Switar 50/1.9 from my Alpa SLR.  I got an Alpa-LTM
adapter from Retina House in Tokyo.  Add one LTM-M adapter the lens goes
onto any M camera.

This lens has amazing resolving power, but the contrast is low due to the
single coating.
