Rollei HFT Sonnar 150mm F4 lens for use with 6000 series. Nice Telelens.

There is an unbelievably long list of lenses that were manufactured for the medium format SLR cameras. As the camera bodies were improved and made more flexible, lens technology kept up the required updates. Whereas Carl Zeiss manufactured all lenses for the SL66, three manufacturers were involved in the manufacture of SLX and 6000-series lenses. The manufacturers were Carl Zeiss,
Schneider, Rollei in Germany and Rollei in Singapore. Lenses are stamped with maker’s name and country of manufacture. Carl Zeiss and Rollei lenses have the HFT coating.

The 6000 series lenses have a linear motor for diaphragm steering and a linear motor for shutter operations. This is been driven by the camera electronics. In this period a very advanced system.
