That is a possibility, but the difference in reaction speed felt rather huge :-) Moving between shadows and sunlight areas would change ISO between about 100 and 1600 in normal TAV, and only between 100 and 200 in the user mode. Anyway, I am using the direct TAV for now since I know what to expect there, and will experiment furter with the user modes when I have some more time. Actually, I feel TAV mode only became usable with the K5's huge dynamic range. I hardly ever used it on the K10 or K7 due to its limitted usable ISO range ...
