    Hi everyone,

    I have a situation that I would like to resolve but I haven't been able to find the correct setup.

    When I have MF assist enabled, I am shooting in any mode, S-AF, MF, etc, if I pull back the ring of the 12mm to use manual focus, the manual focus assist zoom does not take effect, why?

    How can I make it work in this situation?

    I think the ring pull-back prevents the lens from communicating with the camera.

    That's unlikely since I still can control the aperture.

    Did you ever find the answer? I'm having the same issue.

    The whole point of pulling back the focus ring is to be able to do full manual focus, which means focus assists won't work as you're supposed to be doing it manually, you can still use a function button to bring up peaking and/or magnify though

    Having focus assists doesn't mean you are not doing full manual focus. ???

    That is just the way Olympus designed it. When you engage the clutch any focus peaking or magnification will turn off. You can turn them on via assigning one or both to a button, but it won't automatically bring up either when you turn the focus ring while the clutch is engaged and you are mechanically changing the focus (vs. focus by wire when the clutch is disengaged).

    You're using digital assists, so it's not full manual, is it? That's how i see it anyway, it makes sense to me to have assists disabled when going to full manual focus, you can use MF mode (or AF-s + MF) if you want it to automatically trigger, albeit admittingly without the rather nicely damped and limited focusing ring

    On my 12-40 & e-m10, pulling back and turning the ring will automatically turn on any manual focus aids I have enabled, regardless of mode. What lens & camera is this problem happening on?

    Me, too. With the 12-40 and an E-M1.

    As far as I see it, if you are adjusting the focus and making the judgement if the shot is in focus, the that is fully manual. Having the display magnify or peak only gives you something to help your judgement (just like using the scale on a lens for example), but it is sill all you making the decision and setting the focus.

    It was discussed here some months ago and I don't recall if anyone got around to testing it with the 12-40 (I don't have one). But I did test it on the 17/1.8 and pulling the ring would dump you out of focus assist modes and turning it did not bring them back up. As the 12-40 is a newer model they may have changed the behavior for that lens. Also now that I am thinking about it, I haven't retried it since updating my E-M1 from v3 to v4 firmware.

    Same with my E-PL7 + 12-40. I have peaking turned on (and magnify turned off), and it works as advertised.

    With the E-M1 w/firmware 4.01 and the 12mm w/firmware 1.1
    Camera in A, S, M or P mode – the focus clutch when engaged to manually focus does not automatically pull up the focus assist magnify and peaking that I have set.
    When I press the button that I have focus assist set for, only peaking comes up when focusing. If I put the camera in Manual Focusing then the 12mm brings up the magnify and peaking anytime I try to focus, no matter where the focus clutch is set.

    The 12-40mm does automatically being up both magnify and peaking focus assist when the manual focus is engaged from the clutch.

    Although this thread has been going for a few years the information is still relevant with current firmware and cameras ... I have an EM1 and am used to both peaking and magnification in any mode, love it: I recently bought the 12mm 2.0 and it sometimes works in both peaking and mag. I would expect consistency thats all. If I snap it to MF it shows peaking and mag for one adjustment then it turns that function off ( its like oh crap I shouldn't have given you that, back to standard) if I snap the ring back out and in again, I have it for one more adjustment. On my 12-40 pro, 40-150pro, 7-14 pro the full functionality works. I just bought a second body, an EM5ii and can only assign one of the two to one button so chose magnification.
