One other note. I'm not absolutely sure, but I think that ISO, when set to auto, and using Shutter Priority did not bump to 200 when it probably should have.
My settings are:
Shutter Priority / shutter speed set according to lighting.
ISO / Auto
WB / Sunny
I'm sure in MP Business, ISO would regularly bump from 100 to 200 when the 2.8 aperture was not enough in darker lighting. Yesterday, I had a lot of darker lighting and aperture stayed at 2.8 but ISO never bumped off of 100 when the resulting images show that it should have. As mentioned, I know it used to work that way. Maybe something else to check.
