Thanks for all the advice everyone. It turned out that it was a connection issue with the DP-20 and F4. Thanks for the direction @photomemory It's a simple yet annoying fix: push on the back of the DP-20. Anyone know why this connection isn't tight enough? Cheers, Colin

I picked up an F4 a few months ago that was in excellent shape. I wanted to start experimenting with some flash photography, so I bought the SB-24 flash. I've since been unable to get the flash to fire (without film). I know that the flash and camera are syncing to some degree, as the red flash icon is displayed through the viewfinder and the aperture reading on the flash changes as I rotate the aperture ring on the camera. I was considering buying a sync cable to bypass the hotshoe and link the camera and flash using an alternative method. Is this a viable option? If so, what would be the best sync cable? Thanks, everyone. This is my first post! Colin
