Change the F stop ring, and the lens compensates for the focus shift by adjusting the length of the focus tube. ( Note: No cam changes, that would be really pretty wild and complex). Certainly do-able, certainly complex. That means the Nocti would not need a optical redesign. OTOH, according to urban legend, the Nocti glass elements are no longer available/legal/something that will cause a complete optical redesign. If that is true, then the fix is not as 1 sided as noted. They could do a redesign that would take care of most of the shift in the optical components. This seems more likely. So maybe Dr Yao's 50 F 0.9 lens is a reality in the near future, and especially for the M8/M9/M10. Frank Filippone red735i@earthlink.net
