This weekend I ran into a situation in which the K-3 overexposed pictures. I was shooting outdoors under cloudy skies. About 4 pm. The sequence of event was as follows:
Selected aperture priority (A) mode
Pressed the Green Button.
Took a shot to check actual results.
The scene was horribly blown out with a calculated shutter speeds were set from about 1/15 to 1/50. ISO was set at 400, aperture 6.3
I proceeded to go through all settings on the dial. Green mode, program, etc. Green mode came out good as did program (P). When I got to the other options, I always pressed the green button before shooting. I did everything through and including Manual. Results were the same always blown out.
As the green mode worked well, I figured It had to be some combination of settings I had put in and did a "reset". From that point on, the camera behaved as I expected. I recall having made the following settings:
Auto aperture: 100-1000
Dynamic Range settings: Both off
High ISO Noise Reduction: Off
Slow Shutter Speed NR: Off
Program Line: Normal
Exposure Setting: "P"
Auto EV: Off
WB: AWB
Lens: Occurred on two different lenses. Tamron 18-250 and Sigma 150-500.
Has anyone else run into this? Anyone have a hypothesis about what combination caused the problem? As I said, once I did the reset, it is working fine.
Here is an example of what happened on one of my attempts to start out by pressing the green button. (1/160, ISO 400, f6.2, .3 EV)

This is what I eventually settled upon after switching to manual mode. (Picture taken at the same location. 1/400, ISO 125, f6.3, .3 EV)
