Hey all,
If i stack a F to E adapter and then add a megadap E to Z adapter, will I be able to get focus confirmation on my Zf using a Non Ai lens?
I know I can use focus peaking on the ZF but it'd be nice to have the green box.
Would love to know y'alls thoughts.

Not exactly sure about the Megadap but generally works with adapters like that.
But there is a big catch: this works because these adapters will communicate a default focal length to the camera, usually 50mm. This will overwrite any non-cpu lens setting in the camera and if you shoot anything other than 50mm, your IBIS will work incorrectly. Esp with shorter focal lengths the IBIS will actually introduce shake rather than preventing it..

You need an adapter that is programmable for focal length. Not sure if the megadap is, most people I know go F>M then M>Z with a programmable M adapter.

I have the older megadap adapter. I've never tried stacking adapters before so this would a first for me. My dad's friend just shipped me a 55 1.2 Non AI Nikkor lens which he had sitting for a while and then got CLA'd before giving it to me.
I have previously used Sony E mount lenses with no problem on the ZF.

Is this different from a dumb adapter and entering the non-CPU data?
My use-case is adapting an M42 to Z9s. It's only focus-peaking with my current dumb adapter, even with correct focal length / max aperture entered in non-CPU data. Smart adapters are available - wanted to check with you, before buying, that they can produce the green box.

Yes. The non-cpu lens section won’t give you focus confirmation, only functional IBIS for dumb lenses.
You need a programmable adapter to “spoof” the focal length at the lens level for focus confirmation.

Thank you for this. Must have missed it in the Zf adapted manual focus lens thread. How to set with Megadap ETZ21 Pro+:
Enter the camera menu, select ” CUSTOM SETTINGS MENU” – “f Controls” – “f10 Focus Ring Rotation Range” in sequence. By setting the value corresponding to the focal length, the image stabilization performance will be significantly optimized.
