I am now using a Canon Eos T3 with Canon Flash, and ran across my SunPak Auto 622 Pro flash unit in a bag I was originally using for my Pentax PZ-1p film camera. Is there an adapter that would let me join my SunPak Auto 622 Pro to my Canon Eos T3?

I have a T3i, and it doesn't have a PC socket on it either, but I got around it with a Yongnuo RF-603C3 II flash trigger, which does have a PC socket and I plug my old Sunpak 522 into it. Doesn't have TTL, but it works great.
I paid $35 for 2 triggers.

If your flash uses a pc cord but your camera does not, then you can get a hot shoe to pc adapter, such as the Wein hshsb It is a bit pricy, Amazon list it at $50.00.

Older flashes have much higher trigger voltages than strobes made for your Canon. I think the Canon's trigger voltage is only about 5 volts. I have a Sunpak 422 and I think the voltage is 11.85 volts.I also have a Sunpak 383. The trigger voltage is 7.2 volts. The Wein unit reduces the voltage. A Friend of mine uses one one his Nikon D70 with an old Photogenic studio power pack. I would go on Google and see if you could find a site that would have the trigger voltage ratings fo various makes of strobes. You don't want to have a fried camera!.

You have a quality old potato-masher flash.
You need a Sunpak CA-1D module to adapt it for Canon.
It is no longer available from Sunpak.

Here is a working flash with the module you need on eBay for $15.

The flash will safely work with your DSLR, however it will not provide E-TTL.
It only worked in A-TTL mode, and the DSLRS don't work with A-TTL flashes, except in full manual mode.

If you want E-TTL flash, it’s called a new flash.
