I bought it to use on the TECHART LM-EA7. I was prepared that processing might be necessary as it would affect reviews and blogs, but I was able to use it without processing.

It works great and allows you to auto focus with the old wonderful Zuiko on the Sony A7 III!

bought a K&F PK, OM, MD, FD, Nikon, M42, L/R mount adapter for the TECHART LM-EA7 and tried to install it. Unfortunately it was not possible to connect only K&F MD and Flod to the LM-EA7. When I googled LM-EA7 FD LM-EA7 MD I found a mount adapter that was tested for installation.

use a combination of M42 lens, main adapter and VM adapter VM-E Close Focus Adapte α7. There is no practical problem, although there is a slight overflow, the tightening and loosening is smooth, and there seems to be no problem with the working accuracy. If you notice, it's still attached to all M42 lenses. Speaking of greed, I wouldn't say the color is a bit dull.

Perfect mechanics. Tightness at infinity must be checked optically by optics.

By converting the M42 mount to a Leica M mount and using Techart's AF adapter, you can shoot autofocus with the Sony α7III. I can cover up the fact that it became difficult to concentrate because of Toshi. So I bought the M42 lens again because I left it on with the intention of remodeling it straight away. If you remove it, you won't understand.

To mount a Voighlander Leica M lens on a Fuji X E3, very good manual coupling card but a bit thick but that was on the announcement and it could be the optical pressure. So very satisfied.

The processing accuracy is high enough to enjoy various M42 mounts, so you can enjoy it with peace of mind. Old lenses contain a lot of dust, so the fan must be cleaned before mounting.
