My new Nikon D3200 has the rather annoying feature of automatically adjusting my Exposure Compensation whenever I adjust the Flash Compensation (in Aperture Priority mode).
I use Exposure comp as a way to control shutter speed, and don't expect/want it to change drastically when I bump flash intensity minimally.
It doesn't always change, and usually it moves minimally and I don't notice, but sometimes it jumps ridiculously — like an exposure comp jump from -2.0 (set by me manually) to +5.0 (magically) after I adjust flash comp by only one notch (~0.3).
Feels like a bug to me, but maybe it's a feature and the D3200 is just metering terribly. Since I'm new to DSLRs, I'm not sure if this is a typical camera feature to try to adjust target exposure with different flash settings or something. Is it?
