I did some quick test photos this morning with a G1 and an SMC Takumar 55mm f/2. I meant to compare sharpness in photos at various aperture settings, but what really stood out was that while all the pictures from f/2 through f/8 had fairly accurate colors, like this: ...the photos at f/11 and f/16 looked like this: When I noticed this, I did the test again, and got the same results. The light didn't change during the test. Anybody have any idea why this is happening? Is it really something created by aperture changes, or could it be some sort of shift in how the auto white balance is treating the scene? Why would that change with aperture? Any thoughts would be appreciated.
