Japanese camera maker Cosina announced a few Voigtländer-branded adapters that link certain lenses with the new genre of Micro Four Thirds camera bodies. The lens adapters are built specifically for Voigtländer and Carl Zeiss lenses that have Nikon F and Pentax K mounts on them.
Cosina’s new lens adapters offer only a mechanical connection with the camera body, so any type of camera function that requires an electrical interface with the lens – auto focus, face detection, etc. – won’t work with the adapter. Only lenses with a manual aperture ring are compatible with the adapter. A full list can be viewed on Cosina’s web site.
There are several Four Thirds system DSLRs, but the newer Micro Four Thirds standard is still an emerging niche with only two models to its collection so far. Panasonic announced the Lumix DMC-G1 in late 2008 and Olympus introduced the PEN E-P1 just weeks ago. The new Micro Four Thirds standard eliminates the mirror and pentaprism, making it possible for smaller camera bodies.
