[Leica] The SL

[Frank Filippone]

One word answer..... No.

The easy part is the auto aperture.... which is a simple linear actuator
requirement.  The hard part will be the transfer of set aperture to the
body.
I have forgotten ( if I even ever knew)  how the Leicaflex transferred
Aperture information to the body, but I do not think it was electrical... I
think it was a mechanical linkage....
That could be done with a pretty simple resistive element.....   If this
were implemented, it would mean Aperture Priority only.....  ( metering
system adjusts shutter speed to get proper exposures)

Again, my Analog Circuit Design background allows me to think of this... it
does not mean Leica agrees.....

Is there any technical reason why this is difficult (Auto Exposure feature
for R lenses)? Nikon DSLR AF lenses work fine on the Nikon 1 mirrorless
systems, with both AF and AE (most features) enabled via an adapter.
