Focus peaking not working on my M240

I was using my M240 today to check if the RF focusing on my new 21/2.8 ZM Zeiss Biogon was coincident with focus peaking. Focus peaking was not working. I then unpacked my M10-R from the depths of my car, full to the brim coming back from France yesterday and the ZM 21 was shown to be very high contrast. Peaking was extremely bright on it and RF focus spot on with peaking and scale. I then put the APO 35 onto my M240, which I know to be an extremely high contrast lens and no peaking on that either. I checked that focus peaking was on in the menu and even tried changing the colour from red to blue but no luck. Auto zoom is working as expected but no peaking. 

Any thoughts folks? All other things seem to be working as expected.

Did you try it without auto zoom? Resetting that to manual and using the front button might kickstart it maybe? I can’t imagine why it would stop working if it did before…

I rarely use focus peaking on my M240-Ps (as I tend to only use live view via the EVF for framing with wides where I usually want pretty much everything in focus) and when I do I don’t use the zoom feature. 

I think it might have been a tip/remark in one of Jono’s posts that I have always stuck by - using the non-zoomed whole frame and no colour allows you to see the plane of focus as a “shimmer” that moves back and forward as you focus - and allows for off-centre focussing on the 240 which has no option for moving the focus point away from the centre in live view.

I use this very rarely if I know focus/recompose is going to be iffy at max aperture with some lenses for critical focus off-centre (and yes I know I should remember for those lenses whether to lean in a bit or out a bit - but which is which and by how much…?)

Nigel, 

The shimmer is there but no colour. I have not used the M240 for at least 18 months. I was surprised the date did not need resetting. I will try as you suggest turning off the auto zoom. The other thing I might do is leave a battery out for a week or so to force a full reset. I will do a standard factory reset first to see if that boots the peaking into life. The main thing I used peaking for was focusing my Noctilux in low light and checking RF adjustment on lenses.
