GH3 Panasonic GH3 Auto Exposure Adjustment

[Jordell Jarnell]

OK, before you hit the send button, two things: 1) yes, there are occasions where I want the camera to be in control of this particular function; 2) I've researched the heck out of this and have pieced together what I believe does the trick. Looking for validation of that piecing together and, of course, any suggestions.

It appears that the way to achieve this is to set the exposure mode to M, set the Flkr Decrease to 1/50 (doing 24p here), set the mode dial to S, and then set ISO to AUTO ISO (and max iso to your preference). This combo seems to get around certain limitations (while imposing its own of course) and seems to work out pretty well to get the camera to change ISO under changing light conditions. (It seems to work by adjusting the aperture though rather than the ISO; this is evidenced visually by watching the aperture bounce all around with these settings.) Thanks!

It's been a long time since my GH3, but later versions function pretty much identically in the basic, limited, clumsy red button controlled non-creative video mode (mode dial not on video cam icon), but rather on stills-oriented shutter priority auto-exposure (mode dial on S).

So Jordell, setting exposure mode to Manual in menu is totally over-ridden by the mode dial in Shutter priority AE, which, as you saw, varies aperture with changing ambient light. Adding Auto-ISO has no effect UNTIL the lighting falls to the point the max. aperture not enough. Then, ISO varies for proper exposure.

Thanks for clarifying things especially how auto iso (or maybe when) works. I know this is a bit weird but it seems to work in some situations. Of course, there are....pitfalls.
