In theory it would make sense to test the K10D with a lens in the 28mm-35mm range then as indeed you did using the 31mm Ltd rather than going to either extreme. I'm thinking FA 35/2 at the widest aperture and then try FA 28/2.8 with maybe a test using 18mm and 135mm to see what difference is apparent.
