50D Dark Shadow bottom of Frame?? When used with Triggers??

[Oxford_Matt]

Hi,

I have just noticed my 50d is showing a dark shadow at the bottom
of frame when used with Flashgun and The Yongnuo radio trigger off camera.

When used on camera same settings there is no dark lower line or shadow?

Could the trigger be intefering with the camera?

See examples below, Strange this is they did not do this before today??

The triggers are causing a slight delay when firing your flash which pushes the flash past your cameras sync speed. Shoot at 1/200th and it'll be gone.

Btw., which triggers exactly?
My Cactus V2s's did this, but my RF-602's work fine at 1/250th.

You are a Legend!!

Dropped the Shutter speed to 1/200 works perfect.

Thank You!!
