"SB28 flashing"


Miami, US
          

I have an F100 and an SB28 flash unit. I have noticed that sometimes when I put the flash on the camera and turn them both on, when I depress the shutter to half, focusing, I get a quick burst of flash out of the SB28. Is this some kind of pre-flash or do I have some option turned on that I am not aware of. I like the flash, but it is more complicated than the camera itself. Thanks

Yu may have the flash in automatic balanced fill-flash with TTL multi-sensor. (In the flash there is another icon indicator on, at the side of the one showing TTL). If you want it off, just press the mode selector until it disappears, for standard TTL.

I don't think so. It sounds like the contacts are not properly aligned. My SB-28 did that once and it was due to static electricity. Here is what I learned when I brought it in for service:

1) Make sure your contacts are clean. (Clean it with a pencil eraser.)

2) Make sure both camera and flash are turned off to prevent a short circuit (this can also cause the flash to fire) before mounting.

3) Make sure the flash is seated properly on the camera, and the lock is turned to secure it.

4) Turn on the camera, then the flash.

5) If not using it for an extended period of time, take out the batts, and fire it several times to keep the capacitor memory.

Hope it helps.

You are correct Anthony:
The flash has to be clean and turned on after the camera is turned on.

I have experienced the same problem with an SC-17 thrown into the mix. I never had this happen when the unit was mounted on my N90s or N-80. It happened today consistantly during a shoot causing me to underexpose several shots. Can't remember it happening mounted to the F100, but have used the SC-17 almost exclusively with the F100. I shot a wedding with this rig and it happened only a few times. Today, I was wondering if there might be a short in the cord...

I will try Anthony's suggestion and see if that takes care of the unwanted flashing. Didn't have to worry about which one to turn on first with my old 283 and FE's!
