Re: AF Fine Adjustment on E-M1 Mk II

One of the first tests I did with my new E-M1 mk2 in December was to play with the AF Fine Adjustment.

The bottom line is that with my 40-150mm Pro, changing the adjustment had no effect when using S-AF, however it had the desired effect using C-AF.

From this I concluded that (with M.Zuiko lenses and no adapter) S-AF uses CDAF while C-AF uses PDAF.

I did not repeat the test for my other lenses. I was using the regular sized center focus point. The lens was wide open and at maximum zoom.

BTW, the focus point of my 40-150mm Pro did not need adjustment.
