Does anybody know an Leica M to E mount adapter that activates magnifying on sony A7II?

I wish my VL and Leica Lenses would behave like on my Leica M240 where focussing activates the magnifying.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I use the Novoflex on my A7III and have button C4 (the 'delete' one) set to activate magnification.  Works OK for me!

M-lenses have a mechanical contact to M-bodies, via the rangefinder. Sony´s don't. There must be a switch in the M240, an interesting feature.

I have the same workflow with A7II and C2. I have to click twice, for magnifying, you too on the A7 III?

On my Sony A6500 I have a magnifying option of 2 steps. One/two clicks.

on the A7II it is always 2 clicks, first click for moving the focus field, second click for magnifiying 5,9x , third click for magnifying 11,7x

I've heard the auto-focus M to E adapter that works really well.  No sweat to use peaking...

No, just a single push.

Thats good to know, but I really prefer manual focus on Leica M and other analog lenses.

Cool, because next year I will upgrade to A7III

Would you mind to elaborate? I must click twice on my A7s1 with whatever adapter.

I use a Metabones adapter on my R2 and it works just fine.  I will probably upgrade to an R3.  Glad to see that this feature will work well on the R3.

Do you mean that your A7r2 doesn't need a double click to trigger focus magnification?

auto-translatied Post from a german forum where I opened the same thread (https://www.dslr-forum.de/showthread.php?t=1994614&page=2) :

 

I use a 90mm Macro glass from the 70s (Elicar 90 / 2.5 macro medical v-hq). 
Flanged by a simple 10-euro adapter on a 7iii.

If I turn a little (more than "timidly") on the focus ring, the focus magnifier activates immediately in the smallest magnification (you can adjust the zoom level).
The same thing happens with a Sigma ART 35mm, which is mounted by means of MC-11 adapter.
Or the Sony FE 28 / 2.0.

The MF-support detects, if one manually "turns the wheel" ... ... and then activates the magnifying glass accordingly 
(usually coupled to the AF point.) Or I have it configured then - you know in advance, on what you want to focus).

 

With my A7II  it does not work, he uses an A7III and auto magnifying works when he focus manually: 

Can anybody else confirm this with an A7III.

M to E adapters i've used were all inactive in that they have no electrical nor optical contact with the body so i wonder by what means turning the focus ring of manual lenses could trigger focus magnification automatically but i may be wrong.

I guess it is no rocket science for a modern cam chip to recognize manual focus and then to trigger focus magnification automatically 🙂

Do you know one example?

I did read your post above but those are not M lenses are they. I have never heard of a non-Leica adapter allowing to trigger focus magnification with M (or R) lenses so far but again i may be wrong.

Hallo,

Look here: Leica M

You are right! but if this works with an analog manual lens from the 70s without AF electric, I guess it should work with an M lens, too.

The reason why it works must be the chip, not the adapter, I guess

There was an adapter (from Canada if memory serves) that actually had a mechanical sensor to detect movement of the focus cam and make the Sony body aware of it through the electrical contacts.  It might have also tried to read the 6-bit code.  That was several years ago and I don’t think it ever really got out of the prototype stage...
