brill64 Posted October 28, 2013 Author Share #3 Posted October 28, 2013 It's a flash sync issue due to the focal plane shutter not fully syncing. Although your camera will sync at 180/th the radio trigger won't give you that sync speed. Shoot at a slower shutter speed 125/th should be Ok and you'll find that the band will have disappeared Thanks, Paulmac, you're a star..!! I had a strong feeling it was user error & not the fault of the camera. Cheers..!! Link to post Share on other sites More sharing options...

Downshifting to 1/125 seems to take care of it. Pity they couldn't have put a PC socket on the camera. Link to post Share on other sites More sharing options...

Suppose they want to sell only their flash? Link to post Share on other sites More sharing options...
Luke_Miller Posted November 2, 2013 Share #9 Posted November 2, 2013 Pity they couldn't have put a PC socket on the camera. I agree. My Nikon AS-15 in the flash shoe provides one when I need it. Link to post Share on other sites More sharing options...
