Question about Nikon D40 Digital Camera with G-II 18-55mm Lens
I have a Sunpak auto 144 D flash left over from my film days. I've heard that some of the older film flashes will damage the new digital cameras. Any information would be appreciated.
The voltage on the flash hot shoe contacts (center pin and rail connector) can be as high as 140V DC and this voltage is backfed into the camera through its hotshoe connector. There are adapters that can be bought that isolate this voltage that go between the flash and the camera, but different camera makers have different ratings for the flash voltage. My Vivitar 220 has 122 volts across the contacts from 4 AA batteries! Canon recommends nothing over 6v but Fuji says 60v and others dont say anything. SLR's used a mechanical trigger, modern digi cams use an electronic trigger. Also Digcams use electronic metering for exposure so they dont take into consideration the addition of another flash unless they do a preflash, TTL metering and the flash unit is capable of recharging in about 1/10th second. YOu may have to do some post processing or set the camera on manual to adjust the exposure.
