Sigma is part of the L-Mount alliance along with Panasonic and Leica. The three have agreed to make cameras and lenses that conform to that standard.

I am guessing that besides the advantage of the alliance, Sigma moved away from the SA Mount because of the flange distance. The SA mount has a DSLR style flange distance and the whole industry is moving to mirrorless.

There is already an adapter for SA Mount lenses to L-Mount bodies. I plan to get one when the time comes so I can continue to use my SA lenses.

I've heard mention of the flange distance change.  I assume it refers to the distance from the mount plane to the sensor plane.  What changes with mirrorless and what is driving it?
