Cobra 700AF flash unit. Safe to use with ........ ??

14 Jul 2013 8:05PM
I have used a Cobra 700AF dedicated flashgun with a Canon EOS5, and also a Canon EOS1nHS. The Cobra model was on the scene before the arrival of the Canon EOS3, and the EOS 30.
Does anyone know if I can safely use the Cobra with the EOS3 and the EOS30 ?
I have already checked/searched EPZ before posting this, and there is only 1 reference to the Cobra 700, where a member asks for advice re using the same Cobra with a Canon digital SLR, so that does not help me.

Just tried to offer some advice but the site deemed it was possibly 'SPAM' (uhh!!!)

Google 'Wein' adaptor - and if in doubt, get one and use it.

John Smith who created and ran the Cobra brand in the 80s / 90s made sure all the flash guns (including the 700AF) where safe for use on cameras with low trigger voltage. So it should be fine

Having found that my 430EX will not work with my newly acquired 5D mk II, I thought of using the older Cobra flash from my EOS film days, and it seemed to work. Obviously there is no control of flash from the Camera, and you have to set it up manually.
Question: is a shutter speed of 1/60 appropriate, or should I be looking for something else?

Hi I'm still using a Cobra 700af dedicated canon with my old canon D350. it works fine on the canon green auto mode and seemed to talk to the camera !!!! if i half press the shutter button the infra-red lights on the Cobra come on, this is the same if I use it on the camera hot shoe or on the Cobra hand grip. when using in P, TV, Av. and M it seems to work more as a fill in flash, very weak! even using a slow shutter speed! shutter speed seemed to affect the ambient light and the F setting affect the flash! have had to use some tape to cover the left hand side contact on the hot shoe to get full power!
