GH4 & Stills: Does aspect ratio matter?

[acuriousman]

I've been hearing a lot of conflicting info about this.

Is there one aspect ratio for stills that will garner the best quality/dynamic range over all others? I've been hearing 4:3 is the best aspect ratio for stills because it "uses the entire GH4 sensor".

Is this true or will they all give you the exact same quality?

The native aspect ratio for stills is 4:3, so yes, shooting in that ratio will give you full access to the sensor. Shooting in say, 3:2, will just crop the top/bottom portions of the image, leaving you will less vertical pixels to work with.

The ability to change aspect ratios is really just a convenience and doesn't offer you any IQ benefit over shooting native 4:3 and cropping in post (besides seeing an adjusted ratio in Live View).

Video is a whole other matter all together though.

They will all give you the exact same quality,
and I'd be surprised if anyone had said otherwise!
