I have a Nikon SB-28 flash and it works great with my Pentax Program Plus, and gives great results on Auto mode. I just bought an ugly-condition ME Super and it fails to fire the flash. This surprises me. I know my Canon AT-1 also fails to work with this flash, but I expected it to work since my other Pentax did. Is there something different between the two Pentaxen or is the ME Super broken? I already found that the timer doesn't work.
