Voigtländer had two prototype Leica M-mount lenses on display at Photokina:
- Voigtländer Ultron 35mm f/2 Aspherical VM lens: minimum focusing distance is 0.58m, filter size is 39mm, 10 diaphragm blades
- Voigtländer Color-Skopar 21mm f/3.5 Aspherical VM lens: (ultra compact classic design): minimum focusing distance is 0.50m, filter size is 39mm, 10 diaphragm blades
There is no additional information on those lenses (via Dpreview).
Update – here are some details (thanks Licheus):
Voigtländer ULTRON Vintage Line 35mm f/2 Aspherical VM
- Unlike the 35/1.7, top priority is being compact while retaining high optical quality.
- 8 Elements in unknown groups with aspherical element.
- 0.58m close focus, coupled to 0.7m.
- 10 aperture blades.
- Lens barrel length is 28mm.
- The new OLLUX/ LH-2 style hood is optional, but the 35/2.5’s LH-4N hood is also compatible. Which indicates the filter size being 39mm.
Voigtländer COLOR-SKOPAR Vintage Line 21mm f/3.5 Aspherical VM:
- M mount version of the recent E-mount lens.
- Digital optimized – color shift improved over the 21/4 for better performance on the M.
