I just bought a sunpak 383 and am using it straight on the camera's hot shoe and am loving it. The manual adjustments take very little time to get used to. The swivel head is the best - no need for an omnibounce.

Anyway, I found that shutter speed upwards of 320 is too fast for the flash and half the image is dark, actually completely black. I use both flash and camera in Manual. Is there any way around this?

X-sync speed of the RebelXT is 1/200. The camera's instruction manual explains that you need to use 1/200 or slower. It's a limitation of the camera, not the flash. All cameras with focal plane shutters have a similar limitation.

Thanks!
Yes, I know that XT's max sync speed for flashes in 1/200, I've used the on-camera flash with that frustrating limitation for a long time. I guess I should get a flash with high-sync speed option for higher speeds but for now I guess I'll just stick to 1/320.

Anyway, I was not implying that it is a flash/camera problem, if thats how my post came across, it was unintentional. I was surprised I could actually get to 320 w/o any problems.

To be safe I use 1/125th with external flashes.
