I have simply cut and pasted this leader to a thread from the Leica Customer Forum. (I hope this does not offend anyone's sense of protocol). Sounds interesting, especially since Rollei/Carl Zeiss are saying that more than the 40, 50 and 80 will follow (see later on the thread). They are to be available from Jan 03. It will be interesting to see the quality and any responses from Leica. < "Hello everyone, I just received confirmation via e-mail from Rollei USA about the three new lenses for the new Rollei 35 RF camera: Sonnar 40mm f/2.8, Planar 50mm f/1.8 and Planar 80mm f/2.8. They confirm that these (Leica M mount) lenses were designed by Carl Zeiss and will be made in Germany by Rollei of Braunschweig. E-mail from Rollei USA: Here are the answers to your questions: Specifically: 1) Will the three lenses announced for the Rollei 35 RF be made in Germany as is mentioned ("Rollei Germany") on the front of the lens ? YES 2) Who was responsible for the design of these lenses ? Rollei of Germany, Zeiss or Cosina of Japan ? The lenses are designed in Germany by Carl Zeiss. The 40mm is based on the lens design of the Rollei 35 - a world-class lens. The 80mm is based on the design of the 2.8GX/FX TLR lens - again, an amazingly sharp, high performance lens. The 50mm f1.8 is based on an equally impressive formula used on earlier Rollei SLR lenses. 3) Who will manufacture these lenses ? Again, Rollei of Germany, Zeiss or Cosina of Japan ? Rollei fototechnic in Braunsweig, Germany will be the manufacturer of the three lenses. We hope the above information will be helpful.

According to the Rollei Photographic Products catalog (1977), this lens was made of 7 elements in 6 groups. Again, according to this same catalog, the Rollei HFT Sonnar 40mm f/2.8 was made of 5 elements (click on http://www.rollei.tv/35/35_s.htm). As for the Planar 80mm f/2.8, its lens design is traditionally given as 5 elements in 4 groups. For more info, click on http://www.foto.no/rolleiflex/ and The optics. The first lenses are due for Jan 2003, and prices should be very competitive (half that of Leica). Think about it, a Zeiss lens on your Leica M ...
