LUMIX GH4 No longer has peaking solely when using Canon EF 24-105mm 1:4.

It's the weirdest thing. I've been using a GH4 for years and adore it. I have a speedbooster for my EF lenses which I use exclusively. I've always used focus peaking. All of sudden this week my camera stopped peaking. It was on the Canon EF 24-105mm 1:4 (a lens I've had for years). I switched lenses and peaking was back. Only stops on this particular lens. Thoughts? Can't find this issue anywhere else online.

You more than likely have a Panasonic camera issue, not a Canon lens issue.

I suggest that you do some basic troubleshooting. Test the lens without the speed booster. Try testing with a different lens with and without the speed booster.

[EDIT] You might try resetting the camera back to factory default settings, too.

I tried factory reset. If it works with other lenses I'm more apt to think it's a lens issue.

If you are convinced that it is a lens issue, then set up a service ticket with Canon. I’m not certain if that older lens is still being serviced.

You have not convinced me yet that it is a lens issue. Double check the AF/MF switch on the lens before you set up a Service Ticket. Good Luck!
