CP-7m and Chinon S-250 Flash

webkrawler · 12-28-2010, 01:18 PM

Okay, again I apologize for talking about my Chinon..LOL..

I have three CP-7m's and two Chinon S-250 flashes. The flashes turn on
and WILL flash attatched to each camera but ONLY in manual mode. This is
the same for all three cameras and both flashes.

I do have a Chinar-500 flash that works properly on all three camera.

So, I wonder if the S-250 is even fully compatibe with the program/automatic
mode of the CP-7m at all?

Does anyone know?

So if you set the CP-7m in program or in auto mode, the S-250 doesn't fire at all? I'm surprised. The flash should fire regardless of the mode (whether the exposure or the sync speed is correct is a different issue).

With the flash in auto mode, if you set the CP-7m in auto mode or in manual mode with speed higher than 1/125 sec, when the flash is ready, the shutter speed will be set at 1/100; the flash ready LED (red) and the 1/125 LED (green) will light up, and the number "100" appears in the data panel.
