The developer of the M-mount to E-mount autofocus adapter contacted me yesterday to share some more info:
Just to let you know that we will be officially distributing the coming new Techart Leica M -> Sony E autofocus adapter globally. We are now in the stage of pilot run for a small batch and it should be ready by mid/end Jan if everything goes smooth.
If SAR readers have any question please comment this post and I am sure the developer will answer you!
