Sync Porblem 5D

I have a 5D and Hensel lighting. I see a distinct black edge on the right at 200, it is a little less at 160 and totally gone at 125. What am I doning wrong or is my camera a little out of sync?

I was just checking my sync speed with my new 5D and a monolight.
At 250, the second curtain shadow was coming up from the bottom of the picture. The sync speed for the 5D is, I think, 200 but I still detected a slight shadow at 200. It was completely gone at 160.
You say your shadow was on the right side? Did you shoot vertical on that shot?

If you read the fine print in the 5D manual, you'll see they suggest a slower shutter speed for studio strobes.

Strobes have a longer flash duration at low power so this problem is more prevalent at low strobe power settings.

What method are you using to trigger the lights?

5 D sync speed with studio lights is 1/125 th of a second. Kind of hard to find in the manual, but it's there.
Page 102 under Sync Speed.

I shoot with a 5D and Hensels and have found the same thing. I use 125th as stated above and have no problems.

Thank you all for the feed back. I almost sold my 5D because of this. Now I know it isn't just me i feel a heck of a lot better. This is why I am addicted to this forum. Thanks

..."black edge on the right" Sounds like an old cloth focal plane shutter that moves horizontally, rather than a modern bladed metal focal plane shutter in dSLR!!! Are you describing 'on the right' when the camera is in Portrait position?, then that description makes more sense!

It would be the bottom up because I shoot verticle alot. Here is a example and I have done no editing just converted the raw image.
