An "A12 Camera Mount G" would be a boon for the Contax G system owners, but, my gosh , that's a problematic development project for a very small marketplace. Not only is that mount somewhat difficult with its focusing drive from the body only, but it has a shorter register than M-bayonet and several of the lenses have significant back-projection into the film chamber (Hologon 16 T*, Biogon 21 T*, and Biogon 28 T* all have deep back projections and protective rear element guards).... more mount modules, maybe an AF Contax G mount module.
I tried the G2 body, the 16, 28, 45 and 90 mm lenses back in the day. A departure from Leica, looking to see whether auto focus would prove an advantage. All the lenses were absolutely stunning performers, but I absolutely hated the way the autofocus had to be catered to in order to get the results I wanted. I sold off the entire kit pretty quickly and returned to Leica M bodies and lenses.
