Silly answer, I shoot 16:9

I have no idea why my gh3 was set on 3:2 (I normally shoot with the 7-14mm lens); but I was adjusting the settings and noticed that 4:3 files were 16mb and 3:2 were 14mb.

Is there any loss to shooting 4:3 over 3:2; it seems like a no brainer to shoot 4:3 and then crop..but I recall reading that shooting 3:2 actually gives you a "longer" horizontal image vs a 4:3...so you actually do miss some of the subject when shooting in 4:3...true?

[image badly misleading in our context... deleted it]

Check out the pixel dimensions of your results at variously 4:3, 3:2 and 16:9 and see how on some Panasonic cameras the image gets wider as the tops and bottoms get cropped. My LX3 does that and probably your GH3?

Olympus and most other Panasonic just progressively crop the top and bottom to get the different aspect ratios and the width stays the same.

As the image is cropped there is a "loss" of megapixels but if the subject is the same size in the frame then there's no loss of resolution. Same "pixels per duck" so to speak.

In Olympus's case no matter what aspect ratio you shoot (or use 2x digital tele converter) then you always get the full 4:3 image in RAW. I take advantage of that on my E-PL5 by shooting 16:9 to get the biggest possible image on my LCD and then later use the 4:3 RAW to extract whatever I want from the image.
