Deckel to "Pentax Screw Mount" Adapter

use your Kodak Retina IIIS, Retina Reflex, or Voigtlander Bessamatic / Ultramatic on many other SLR bodies

What's a Deckel? Deckel is the manufacturer of Compur shutters, and apparently the inventor of the very similar  Retina IIIS/ Retina Reflex / Voigtlander Bessamatic / Ultramatic mounts.  These mounts are often referred to as "Deckel" mounts in Japan.   The Deckel adapter can mount all 3 mounts on the so called "Pentax screw mount" cameras, which really first appeared on the East German Zeiss Contax SLRs.   The adapter links to the lenses to provide manual aperture control, as well as linking to the movable depth of field scales.  You will have stop down TTL metering, and whatever other extras that particular body will allow with stop down metering.  Shown is the Voigtlander 50/2 Septon lens with two adapters, and the excellent but little heralded Chinon CE-3.

The adapter will work fine on most 42mm screw mount bodies.  However some bodies such as the Fujica 801 and 901  have metering lugs which prevent the adapter from seating completely.

Have you ever wished for TTL flash, spot TTL flash, motor drive up to 5 fps, your choice of average, centerweighted, or spot metering, up to 9 multi spot meter readings, waist level finders, action finders, or 250 film backs for your Kodak Retina IIIS, Retina Reflex, Voigtlander Bessamatic, or Voigtlander Ultramatic?  NO PROBLEM!  Just use the Deckel adapter plus a Pentax Screw to Canon FD adapter, to mount those lenses on the Canon T90 or Canon F1.  All of the above functions are at stopped down aperture: there is no linkage between the adapter and the camera.

That's right folks, you can add a Pentax screw mount adapter to the Deckel adapter, and mount your lenses on a wide variety other SLRs, including Canon FD, Canon EOS, Konica Autoreflex, Miranda, Alpa, Mamiya XTL, Olympus Pen F/FT, Rolleiflex 35 SLRs, Zeiss Ikon Icarex, Pentax K, Fujica X bayonet, and Contax/Yashica SLRs.  My oh My, think of the possibilities.
