Probably because I'm using too low a shutter speed, have to remember that! But in low light, even with TAv ISO going up to 1600, sometimes it just doesn't work out. Cameras!
At PF, many people recomend Tav (aperture priority) but....Personally, I tend to prefer using Shutter priority (Tv) because I shoot handheld and Tv helps me selecting a shutter spped fast enough.
In fact, to be perfectly honest, I shoot in Hypermode P and I set the wheel to set the shutter speed when I see that it is too slow.
My 5 cents...
