Originally posted by limbonaut I'm relatively new to Pentax so forgive what might be a newb question; but what do you get from TAv mode that you don't get from simply using the front and rear dials in P mode?
On the K20D, TAv been very important from me shooting U7 & U8 soccer with a 50-300/F4-5.8.
I fix the shutter speed to a value high enough to prevent motion blur: 1/500s-1/1000s.
I also fix the aperture to a value in the f/6.3-f8 range to get enough DOF to get multiple players in focus at high FLs. These very young players bunch up a lot and I like to get clear shots of most of them as their expressions are great.
Using TAv, I can do this and the ISO roams between my set limits of ISO100-ISO1600 depending on the light level.
Anther use of TAv is with adult daytime sport where you want a high shutter speed, a wide aperture (say f/2.8-f/3.4) to isolate the sole subject from the background, and let the ISO roam.
