K-3 Mark III: Does Firmware 1.10 affect AF Fine Adjustment?

**c.a.m** · 09-22-2021, 02:44 PM

Hi,

I have not yet updated my K-3 Mark III to Firmware v. 1.10 or 1.20

I believe that certain firmware updates in at least one other camera model required the AF Fine Adjustment settings to be re-calibrated.

Has anyone experienced this issue definitively in the K-3 Mark III after installing FW 1.10 or 1.20? Did you need to set new AFFA values for optimal AF?

Thanks.

- Craig

I think I had to re do several of my lens after the latest update. the first AF fine tune on all lens was June 3rd. July 25th I checked them all again and discovered I needed a minor adjustment on my 55-300 PLM (that may have been from a bad fine tune originally. On August 11th all my lens were checked again and all needed additional adjustments. I'm not sure if those dates correlated with firmware updates or not.

Thanks for your replies.

It will be interesting to hear if any other users had to re-set their AFFA settings.

So far I've had to re-do mine with each update.

Same question for Firmware v. 1.20.

It does for 1.20. I confirmed it my for Pentax lenses. I don't have any third-party lenses to check against so I don't know if it works for those.

Not sure if I was clear with my question.

Did your lenses need new AFFA values?

Not that I've noticed. They all seem to work as expected.
