I ordered and received a PC cord and tested it with no film in the camera, and it seemed to work fine, but once I got a bracket for it and tried to use it with film in the camera, the flash would intermittently not fire. I've tried lots of different settings on both the camera and the flash and the problem persists. Once I take the film out and test it again, the flash fires every time. Any insight on the cause would be greatly appreciated!

I've just solved my own problem. When using the SB800 Speedlight with the standby mode set to Auto, the flash unit goes into standby after each exposure. When using it with a Nikon DSLR, autofocusing takes the flash out of standby and readies it to fire. This is not the case when using it with a TLR and a simple PC cord. Once I went into the flash settings and turned standby mode off so that the unit was always on, the unit fires every time. The reason why it "seemed" like it was working with no film in the camera was because I was testing it by releasing the camera shutter several times in quick succession, whereas when there was film in the camera I was waiting a few minutes between exposures, allowing the flash to go into standby. It seems like a no brainer, I know, but I guess when you go from a fully automatic DSLR to a totally manual TLR, sometimes simple things can escape you. I'm just really glad I have it working now!
