645DF Auto Focus Settings

Does anyone recommend proper auto focus settings for the DF? I am new to this system and so far its pretty good but wondering if my settings are right...

What are you using the Camera for primarily?
That would help to tell you the best workflow options. However, the DF really only offers Fast and Accurate as Auto Focus options. Fast is to decrease delay, best used on a Fashion Shoot for example. Accurate will do 2 or 3 checks to ensure proper focus before allowing capture, best for Landscape and Still life.

You'll want to use the "Fast" focus setting then.
I would also recommend that you change the AF button to the back "AEL" button of the DF, and have the shutter button be ONLY for shutter actuation. This gives the camera a bit more stability when hand held as well as reduces any "shutter lag" due to a focus hunt when you're trying to just take the picture.

Frank just keep in mind that focus accuracy in fast mode is not that good.
The manual recommends setting an f-stop of F8.
It's buried in the manual somewhere.

Do not expect to get the best sharpness consistently out of your
camera when set to fast focus.
