Voigtlander 40/1.2 M vs FE

[squirrel$$$bandit]

I've been contemplating a Sony A7-series camera as a digital companion to my M4, and was ogling the images from the 40/1.2. I wonder if there's any advantage at all to getting the native FE version instead of the M? Obviously, if I go with the M version, I could adapt it onto the Sony. Is the adapted M version the same size as the FE? Is there any difference in the glass, etc.?

Thanks
John

A great explanation here on the head bartender's other website:

Ah, thanks. But surely image stabilization is also available for adapted lenses on all cameras that have it? And manual focus assist can be manually activated regardless, right?

With the Zeiss Loxia series of lenses for the FE mount, there was a change in lens formulation (compared to the ZM mount) to work better with the A7 series thick cover glass. I haven't seen if there is a difference with the Voigtlanders. I'd advise looking for lens tests on the web that are aware of the problems of some lenses with the A7 sensors, or going to a dealer and trying both FE and M mount lenses on an A7 while looking closely at corner performance. Good review of an FE mount 40/1.2 here:

A couple of difference between the two lens the Sony FE version is larger and when you turn the focus ring the camera automatically zooms in to help you focus 1:10-1:15 seconds attached videohttps://www.youtube.com/watch?v=KC8lHcnVBmg&t=80s
