Hi all

I just picked up a Nikon SC-28 cable for my Nikon SB-25 which has TTL mode (I read the wire would be compatible). When I set the flash to TTL mode the camera has a lightning bolt at the 1/50 shutter. The flash makes it's charging noise and everything seems good to go -- until I press the shutter and nothing happens. What's going on here?

Notes:

• When I set the flash to Auto it fires with a big flash
• Flash in TTL mode does not do anything, I set the flash aperture to match my camera
• I tried in low light and also in a dark room, both didn't trigger anything

Thank you

Certain Metz flashes will work in TTL mode with an adapter but I don’t know of any other non-Leica brand flash that does with an M6TTL.

I found the answer, needs to be set to Auto. Hope I didn't mess up any electronics.
