[Leica] 75 'cron now 105 F1.4

[dorysrus at mindspring.com (Don Dory)]

Seth,
The 105 F1.4 was assuming use of the 75 Summilux on an APS C digital
camera.  Fifty percent crop factor would give you something in the
neighborhood of 105-110 effective focal length.

I wonder if anyone has mounted a 75 Summilux on the RD-1?  Howard, Dr.
Yao, Frank, anyone have both the RD-1 and the 75 Summilux?  Want to
chase attractive faces to see how this combination works?

Don, I'm forwarding your post to Stefan Daniel at Solms; it seems to me
that 
input like yours should be invaluable to the planners at Leica. Only one

disagreement with you: I do not believe that a 105/F1,4 is possible for
two 
reasons, one because I think that even if it is technologically
achievable 
it would be ferociously expensive and monstrously heavy and bulky and
two, 
perhaps more important, I do not think it would work on an M-camera, the

bulk of such a lens would block the viewfinder.
