Unfortunately I haven't tried it yet. I was unconvinced with most M lenses under 50 mm with the A7 when I had it (smeary corners). I was using a Novoflex adapter, which may not have been perfect. I'm still expecting to use the A7ii mainly with native lenses and R lenses (but I'll be trying M lenses with the VME
Thanks Jono. I understand and recognize your also previously stated points of view. The reason I ask is that I have a Canadian adapter that starts to vignette a bit a 90 mm and severely for 135 mm focal length for FF sensor. For 75, 50 mm and below it is fine.
Quoting from
Hawk's Factory Leica M L M to Sony E Mount Macro Tube Helicoid V3 for 135 FF | eBay
"There are several parts of this improved version,
1, Stroke remains to 5mm,
2,
RF lens can be up to 135 mm focal length,
3, Infinity can be adjusted according to the lens,
4, you can lock it at infinity,
5, no longer see oil inside of the hole,
6, the contacts completely out of the way,
7, the lens release button narrow than V2.5,
complementary
V1 ~
version 2.5 can be used to the 75 mm focal length lens
The following is a test version 2.5 on A7r
75 no vignetting (leica 75/1.4)
90 vignetting will occur (leica 90/2 AA)
35 no vignetting, no red edge (LEICA 35/1.4 ASPH 11663)
So, I am looking forward to your experience with the VME adapter.
Thanks again.

The product is very nicely made.However, the Close Focusing mechanism intrudes such that it is less than a full frame opening. 50mm and shorter is okay. But my F4 135 Elmar and my F2 90mm Summicron have a small but hard vignette in the corners. I also have the Novoflex adapter. It does not have this problem.While the Close Focusing feature is very handy for my 28mm and 35mm lenses, I wouldn't have spent this much money if I'd know that it doesn't fully work with the longer lenses."
