Version 1 of the SL II 40/2 AIS lenses with rubberized focusing barrels. Version II with all metal focusing barrels are $489. These are new versions of the previous limited edition Cosina made Topcor 58/1.4 of a few years ago (produced in chrome for Nikon AIS or Pentax M42 mount). The superbly performing Cosina made Topcor 58/1.4 is popular and very sought after in Japan. Unfortunately it sold out too quickly for most other markets to be very aware of the lens. and See previous versions here http://www.cameraquest.com/Voigt SL.htm
Although the new SLII lenses have the same glass as the previous versions, there are very important differences:
1) both are chipped for full metering capacity with digital SLR lenses. This is a first for Voigtlander Nikon mount lenses. While covering the full frame 35mm format, they are also ideal fast lenses for Nikon digital SLRs. With Nikon discontinuing most of their manual focus single focal length lenses, Mr. K once again offers lenses not available elsewhere.
2) Both new lenses are available in black only. The new version 40 now includes the interesting dome lens hood (previously sold separately) and a close up lens. the 58's lens hood is sold separately (previously included)
3) $449 for 58/1.4 in Nikon mount. $59 more for the 58 lens hood.
