Nikonos magnets? Can you be more specific for me.
Is this something that would apply to my 5000.
The strobes ship with a magnet use to set how the it interfaces with the TTL signals. There are two positions for the magnet plus you can leave it out (total of three settings). Nikonos-style cameras (including housed Nikons) are supposed to get the "N" setting. Since the D100 is a D-TTL device, using the N setting with a TTL bulkhead causes the camera to malfunction (turn off). Removing the magnet fixes this.
Sorry this is off-topic for Canon users. Inon magnet settings could sure use some clarification.
