How to use a Manual flash on Nikon D300

2 years 7 months ago #546127 by iKokomo
I have an older manual flash that connects via the PC Sync port (the trigger voltage is 6v so it is safe) so when I plug it in and take a photo, the flash does not fire. The test button fires the flash so I know the bulb is ok.

I have also tried the pc sync to hot shoe adapter on a couple of Nikon cameras and it still does not work.

Is there a menu setting on the camera that I need to set for manual flash mode? I know there is a setting for manual lenses is it the same for a flash?

Thanks!

I'm assuming the flash is a TTL unit. Well, the camera has iTTL circuitry and is looking for different info than what it is getting from the flash unit. I'd suggest taping over the two pins on the flash foot, leaving the center pin uncovered and the single pin on the other side. You may have to cover that single pin up as well, but I don't believe so. If it still doesn't work then cover the three pins up with scotch tape. That's what I had to do with an older dedicated ring/point light until I switched out the flash module to the standard (single center pin) one.

Out of curiosity, what brand is the flash? My previous reply was using it in the hot shoe but on re-reading your post, you said you were using the PC sync port. I would try another sync port on a unit that sits in the hot shoe. Actually, I would get a newer unit that syncs better with your DSLR. I have a D300 (and a D7100 & D610 as well) and I also have older film era flashes (SB25 & SB28)but use my SB600's instead. I use the other older ones in slave modes...

I agree on getting the newer speedlight that mates to the Nikon camera....

Why so serious?

I believe that there is a manual flash mode setting in the menu of the D300, however that PC port on the camera body should fire a flash ever time the shutter button is pressed. If we assume the pc port is working on the D300, that leaves the cord as suspect. Radio triggers are very inexpensive on ebay and very reliable, you might want to get some anyhow .... as well as a Nikon or comparable flash.

It is what it is.

Since it's safe, have you tried the flash unit in the hot shoe? If that works and you want the flash off camera, trigger it with radio triggers. Still waiting to know the brand of the flash...

I'd pass out in three seconds if I tried, besides the OP may just be shopping a nice, lightly used SB-600....
