psb Posted October 10, 2009 Share #1 Posted October 10, 2009 Advertisement (gone after registration) Hi, I'm hoping someone can give me the definitive answer re: the use of a Vivitar 283 on an M6 TTL. I've heard so many different answers my head is spinning. Some say that only the 283 produced in China can be used. Others say the 283 is fine. Then again, others say neither the 283 or the 285 can be used. I'd be most appreciative if someone could give me their insight. Many thanks. Link to post Share on other sites More sharing options...

To be 100% sure you can measure it yourself with an inexpensive digital voltmeter. If the voltage is less than about 15 I wouldn't hesitate to stick it on an M6TTL; if it's more than about 40 V I'd use another flash or get a "Safe Sync" or similar.

charlesh Posted October 10, 2009 Share #4 Posted October 10, 2009 I've used the 285HV on a Contax G2 many, many times without a problem. I used the flash just once on my M6TTL, and the results were fine. Link to post Share on other sites More sharing options...
earleygallery Posted October 10, 2009 Share #5 Posted October 10, 2009 I'm no expert on the subject but surely any flash on an M6 will work fine? I think it's only digitals that can suffer? I have used a Metz 45CT1 on a digital - didn't occur to me there may be voltage issues - with no ill effects. Link to post Share on other sites More sharing options...

I have used a Metz 45CT1 on a digital - didn't occur to me there may be voltage issues - with no ill effects. It's not digital cameras but cameras with electronics. There must be some electronics in the flash circuitry of the M6TTL or it couldn't deliver TTL flash control with suitable units, so it's a fair question whether a high-voltage flash unit could be a problem. Also, not all 45CT1 guns have a high trigger voltage. According to the Metz website it's only ones with "a model number that is smaller than 534 000".

Thanks for that, checked mine and its above that number which surprised me as its an old battered one which I bought off another member here a few years ago (I like the fact its old and battered looking, especially the masking tape which holds the battery unit in!). Invaluable flashgun for me anyway! Link to post Share on other sites More sharing options...
tobey bilek Posted October 15, 2009 Share #8 Posted October 15, 2009 Use the Wein Safe Sync. Have the camera and flash turned off when connecting and disconnecting. There will be no problem Link to post Share on other sites More sharing options...
