I agree. I don't see the point of Sv at all. I imagine there's a Sensitivity Priority Anti-Discrimination League out there somewhere that lobbied for putting this on the dial. But on a K20D, is there any difference at all between Sv and, say, P mode with the ISO set to a fixed value?
Quote: That's what I'll probably do anyway or try to use the M mode for full control. But the Tv/Av are not as good as the TAv. The problem comes from the camera choosing a shutter speed relative to the focal length, using the old 1/fl rule for hand-held photography. But with SR it's often possible to gain at least 2 stops. Unfortunately the camera doesn't seem smart enough to know that.
Yes, I understand. As I've said here many times, TAv mode is one of the things that I really like about the K10D/K20D. Well, I should add that I liked it more when I was shooting almost exclusively in M; TAv was then a nice switch if I was shooting in variable low light. But for many months now I've been shooting mainly in hyperprogram (P) mode, and moving from P to TAv now requires more of a change in the way I calculate exposures and I find it disconcerting. I just shot my first wedding entirely in P (switching of course to functional Av or Tv by moving one or the other e-dials while the mode dial was on P and adjusting EV as necessary). Results okay, although having to switch ISO manually throughout the afternoon and into the evening was a more of a hassle than I had expected. Perhaps it would have been better to shoot M or TAv after all. Still trying to make up my mind.
One other note. Before I got my K10D a while back and learned about TAv mode, if I was shooting sports or something else in low light, I generally just shot in M, with a fixed ISO. I'd have to watch the meter, of course, but I'm used to that. But I could put the camera on, oh, ISO 800 or 1100 and just deal with the noise later. Another option to consider with your K-m.
