Pen F autofocus vs. OM-D E-M1 (either version)

I own both of these cameras (E-M1 mark I, Pen F + E-M5 II).

CAF on Pen F is close to useless. Contrast detection in a lower light is the slowest on Pen F but the difference is not huge.

Anyways if you need far superior AF in bad light rather get a Panasonic camera. GX8 AF speed and accuracy is amazing. By the way I'm waiting for GX9. This camera will become my main camera (and yes mainly for its superior AF accuracy compared to Olympus cameras but also for other features like their great implementation of touch AF).

Hello Dunsun,

All of the noise about Panasonic AF seems to be this DFD stuff. Is that in play when an Olympus lens is on, say, a G9?

Hey,

It's not only about DFD. DFD is used mainly for CAF AF. But Panasonic uses superior AF algoritms even for SAF.

Anyway I was owning Olympus 17mm 1.8 and yes this lens does better on a Panasonic body than on any of Olympus camera I have owned (all except E-M1 mark II). Especially at night Panasonic can focus almost in a complete darkness.

Sadly it does not work the other way around. Some Panasonic lenses can strugle on Olympus bodies. First they do produce magenta fringing and flare on Sony sensors, second they can suffer from a AF hunting. Like my Panasonic 15mm 1.7 (amazing lens) on my Olympus cameras. On my previous GX8 it was lightinngly fast and accurate to focus in almost any light conditions not so with my Oly cameras.

Cheers
