Standard ISO Hot shoe: PART2
I have a Canon EOS5 camera with the Canon Speedlight 380EX flash unit.
I am advised by my camera shop that the flash is not compatible with my Nikon 5700 and that it could damage the Nikon... Can anyone confirm this? Or is my local camera emporium hoping to entice me into buying another flash unit at a couple of hundred??!!!! Help please...Tnx -- Donald Gray Putting ODCOMBE on the Global Village Map! www.odcombe.demon.co.uk You do not have to email me, but if you wish to...

Go to http://www.adorama.com and search for "safe-sync". You will find four different versions of the Wein Safe-Sync adapters. B&H has them also. http://www.bhphotovideo.com search for "safe-sync". I have a diagram of a DIY unit on my site. http://www.carlmcmillan.com/Optoisolated_Adapter.htm -- CSM1 http://www.carlmcmillan.com -- CSM1 |

Nikon and Canon use completely different signalling contacts - only the main center contact is standard. At best, the Canon 380EX will always fire full-power on your Nikon camera. At worst, you might damage the electronics on either or both the camera and flash. -Dave Dave Herzstein |

Dave, Thanks for confirming what I already suspected. I shall not be using it with the 5700. regards -- Donald Gray Putting ODCOMBE on the Global Village Map! www.odcombe.demon.co.uk You do not have to email me, but if you wish to...

Re: Standard ISO Hot shoe: PART2
The standard hot shoe contacts are:
The center contact is usually the normal full power, no TTL control contact with the metal mount being the ground or common. You may have to experiment with the polarity. If you have the wrong polarity, the strobe will not fire. -- CSM1 http://www.carlmcmillan.com -- "Donald Gray" <> wrote in message news:... > On Mon, 27 Oct 2003 15:21:33 GMT, "CSM1" <> wrote: > > Carl > Your reply is just the job.
