Can I override a Canon Rebel XTi's Tv setting's 1/200th sec limit with a flash?

I need 1/500th of a second with a flash for indoor basketball. I know you can do it with a 30D but I'm not sure about a Rebel.

What you need to know is the sync speed... this is the cameras ability to open and close the shutter in perfect timing with the flash. Unfortunately your camera only has a sync speed of 1/200th of a second. However none of this matters anyway as the flash is not powerful enough to reach the distance you will need to be at to illuminate a basketball player, this flash will work up to about 15 feet, you can probably push it up to 30 feet if you up your iso setting to 400 or 800 (don't forget that the higher the iso the more noise you will have, so this means really grainy blow-ups later, your best best bet is to attach a 580EX flash to the flash shoe on top of the camera. When I shoot concert photography I don't use a flash at all and just up the ISO to 1000 or more, but I am not worried about the high grain with concert photography as it looks kind of cool. It helps also if you have a lens that can go down to f 2.8 or lower as this allows you to shoot in less light.

Don't worry about the flash I would do some tests shooting on aperature priority mode at your lowest aperature, (remember zooming in means you lose light so don't zoom in if you don't need to) and set to a livable ISO like 400. So set your camera to f2.8 at 1/500 at iso 400 This should work in stadium lighting. if you are at your lowest aperture the only thing you can do to get more light at this point is keep upping your iso,

Good Luck

I actually called Canon and they told me how to let it go to 1/500th with my flash. It works fairly well in use. Thanks!

Yes, there are ways to cheat the sync speed. Some people can squeeze quite a high shutter speed. Especially out of a Nikon.

Whether or not it's necessary or useful is up to the photographer. Sometimes it's just seeing how far you can push the equipment.

The asker was happy with the answer so I won't elaborate but a good site for camera tricks and tips is http://strobist.com
