Can you tell me how these lenses will work on a Canon mount. Do you adjust the aperature on the lens and then the shutter speed will be set auto or will the Leica lense only work by setting both manual?
Same as all non-EF lenses on an EF body ... they work in Av mode or M. In AV mode set the aperture to maximum, focus, reset the aperture to what you need and shoot. The body will set the shutter speed to what it thinks is appropriate.
Sounds more difficult than it is.
