Shutter speed Limits while using internal flash!!! 550d

[Xkey]

Hi

Ive recently bought the canon 550d and was looking into getting a underwater housing. The Sea & Sea RDX550d is looking very appealing.

But after taking several shots and slowly learning the camera ive come across a restriction of the cameras shutter speed while using the internal flash to trigger my Sea&Sea YS110a strobe (Optically). U can only use speeds of 1/200 or slower while the flash is popped up!!!

So..... My question is does anyone know how to get around the fact that i will be using the internal flash to trigger a strobe but may require a faster shutter speed than 1/200 sec

Is there a menu option i haven't come across or possibly a firmware update to get around the limitations.

Any help is much appreciated

Xkey,

You are correct, 1/200th is the limit. There is no way around it. In general, people are fine using 1/200th - if they want to block out more ambient light they simply close down the aperture. In general it will not be a huge deal. The strobe will freeze any moving subject that it lights up.

hope that helps,
Scott

Cheers for the reply Scott

Ive just done a little more research about the limitation and found that that is the highest X-sinc (Full curtain opening) my camera has is 1/200 while using the flash, my issue was will this not cause motion blur if i require a higher shutter speed for the worlds fastest nudi or something
But looks like I'll just have to maybe try panning... lol

The strobe will freeze any moving subject that it lights up.
