[Leica] Metering on Canon DSLR with Leica R Lens

[joseph at yao.com (Joseph Yao)]

Hi Lee,

In addition, with a non-Canon EF lens mounted, there is no lens as far as
the camera is concerned and the only metering mode available is
centre-weighted.  I do not think you can access matrix or spot or partial
modes.

What research did you do on this?

Bests,

Joseph
