Tv's a good no-brainer for action shooting, set 1/500 and run with

I've always found that the hard part with shooting sports is
getting the balance between how much light is available and how
much speed you need -- rarely have I come across a situation where
I actually could have set the camera to 1/500 and then let the
aperture fall where it wants without being up in the ugly ISO range.
My suggestion is to figure out what you need, what you can get away
with, and how close you can get to it without going to ISO 1600 --
I figure out a target shutter speed, determine what ISO I can use
with that speed and with my fastest long lens wide open, and then
go from there. If I were running on an automatic mode, it would
likely be AV -- using TV, a drop in light level would mean a drop
in exposure, because the lens would already be wide open or really
close to it. But if you're using AV and getting around 1/500 at
f2.8 and in the slightly dimmer corner of the stadium your shutter
speed drops to 1/400, well, no biggie.
Hmm. My issue is typically the reverse. For the kinds of action/
sports stuff I shoot (mostly motorcycle racing), I use Tv to lock the
exposures down in the 1/125 to 1/250 range because faster than that
there is no sense of motion recorded. Auto ISO works pretty well most
of the time, even with a ceiling limit of ISO 1600. I normally shoot
these kinds of things with a maximum 135-200mm lens.
Different situations, different strategies I suspect. Ball sports
would require longer lenses and higher shutter speeds ... thankfully,
they bore me to tears so I never shoot them. :-)
