TAv mode — do you use it?

I wouldn't say that TAv is the most useful mode but it certainly does have its uses.

It's a fundamental principle of digital photography that you should always use the lowesr possible ISO to maximise DR and minimise noise.  Whenever possible, therefore, I use an exposure mode that lets me choose ISO.  For example, if I want control of DOF (whether narrow or wide) I use Av and let the camera determine shutter speed.

It's when the light gets too low, or if I need to control both aperture and shutter that I go to TAv.  How often this happens is obviously personal; for me it's under 5% of all the shots I take.
