I do not know all that much about optics - so this may be a nonsense
suggestion - but if the bodie can not extent focus further in order to
achieve focus gloser than 2,6 M - with out expensive changes would it not be
possible to make that change in the lens instead - like the colabsable leica
lenses from the screw mount leicas - to a lot lower developement cost ?? -
lens pulled out would be 1 M to 3 M and pressed in 3 M to infinity ??

Tele-Rolleiflex?
Yes Peter, that's evident and I agree with you, however I'd add the new tooling costs as decisive to suspend the project, the FX and FW also have a limited market today but Rollei is manufacturing them yet, they did not doubt to launch the FW on 2002 because they could use for it almost the same tooling used to manufacture the FX. BTW, I think Rollei already has the prototype for the new Tele, I remember both FW and Tele were introduced in Japan around 2000 or 2001, however the protoypes are hand made and the investment for new tooling dedicated to specific models is very high, a failure for this investment always was one of the main preoccupations for the old F&H; in fact F&H had almost ready for production a new Tele prototype around 1965 with a long focusing travel based on the Rolleicord focusing mechanism and a 145mm lens allowing the shortest focusing distance at 1m without supplementary lenses, but Rollei decided to invest for tooling to manufacture the SL 66 and the Rollei 35. BTW there are several collectors and photographers with money waiting for the new Tele, this is the reason Rollei explain why they suspended the new Tele production, but their number is not sufficient to risk an investment for new tooling.-
All the best Carlos

Carlos, I think the last paragraph says it all. Limited market. Hence the real reason for the cancellation. Rollei needs to make money to survive, so putting R&D into a product with limited appeal is not wise in this day and age. Peter K
