<p>The only thing that one needs to be careful about regarding the DKL mount adapter is that, there is a version of the DKL mount used by Voigtlander Vitessa T and Braun Colorette, which is for rangefinder cameras only and is best identified from the lenses -- like usual rangefinder lenses, they have the aperture rings on the lenses rather than on the camera bodies. I see them being sold on eBay as well. They are described as DKL mount adapters, for use with Voigtlander Vitessa T lenses, so it is not difficult to tell them apart from the adapters for Retina and Bessamatic lenses.</p>
<p>I have a page with photos of many DKL mount bodies and lenses, including both versions:</p>
