Focus peaking problems

[Franky]

Hello,

I bought a Novoflex adapter (Nikon lenses on Leica m) for my m10.
So far everything is fine, but the focus peaking and the enlargement in the live view probably do not work. Bug or feature?

best regards

Such adapted lenses do not move the focus cam in the body, so it has no way of knowing your are focusing. A button press can still activate the enlarged view.

Thank You, which button?

Yes, as Tom said, front button "focus" press as usual,

then rear wheel to change magnification ratio.

To be clear focus peaking has nothing to do with the focus cam, it works via LV or Visoflex based on edge contrast. It does definitely work with a manual focus Nikon lens on an adapter and you would need to use LV/Visoflex to focus this combination anyway. I can't say why your focus peaking isn't working, perhaps not the right combination of buttons? I suppose you could try making the peaking effect stronger in the menu, and of course focus wide open for critical focus and then stop the lens down to the shooting aperture.

A Leica M lens switches on the focus assist (i.e. focus peaking and magnification of the LV image) of the M (Typ 240) when you turn the focus ring. The camera body detects the motion of the cam. Uncoupled lenses obviously don't do that, so you have to turn on the focus assists manually by using the button in front of the camera, as has been said (and as explained in the manual). Presumably, it's the same with the M10.

Focuspeaking can also be bad or even not possible on low resolution lenses that are rangefinder coupled and used wide open.

Yes, the focus button was the solution.

Focus peaking and the enlargement in the live view work fine.

I didn't know the use of this button

Thank You

Just a service information:

The front button of the M10 has 3 different functions:

        1.  Manually switch On/Off the focus enlargement when using LV or EVF

        2.  Setting the exposure compensation while simultaneously turning the back wheel

             (alternative of using the menu)

        3.  Setting long exposure times (8 sec … 4 min) not indicated on the shutter dial

             (pressing the front button while in Bulb gives a new set of long exposure times)
