Speedlight 299T for 6D

I was wondering if it is ok to use the Canon 299T on the 6D. I read elsewhere that voltages need to be right to avoid frying the camera innerds. Your thoughts please.

Hi,
According to:

you should be OK.

Canon DSLRs (not G series etc) from the 20D onwards are good to 250V according to Chuck Westfall.

I presume you are aware that all flash automation is off, when not using flash units with the EX designation. The earlier EZ aren't E-TTL compatible, and the T series is even older.

Yes I am that automation is off. Thank you. More of a issue of concern that if I plugged it in by mistake, I wouldn't cook the camera. I know, I know, I should always be aware of what I am plugging into my camera, but there is always the possibility of a brain fart.

I have a 299T and while it has a TTL mode, it also has the earlier "Auto Thyristor" mode and can function very well in Auto mode on your 6D. Just select "F.NO. SET" mode on the flash, and then match the aperture and ISO to your camera settings. (I would use manual mode on the camera)

These old "Canon Dedicated" flashes not only can do Auto, they also will limit the shutter speed to the camera's max sync speed and show a lightning bolt icon in the viewfinder when the flash is ready to fire.

I have this flash. It works pretty well in Auto thyristor mode, and as far as I know, it's the only thyristor flash with full range available f-stops from f2 to f22 for all ISO's it can handle. This is important because you can shoot high ISO's with large apertures like f2 etc. You can also change ISO on it to act as flash exposure compensation.
The cons are: 1. bulky 2. no HV port. 3. recycle time 5 secs for full manual pop with Eneloops (though I made a 9.6V DIY battery pack which reduces recycle time to 3 secs).
As for sync voltage it' like 6V as reported by the botzilla site, and it works fine on my 5D II
