Will it fry my camera?

[50mm]

Can someone tell me please, if my older Flash QUANTARY PZ-1 DSZ
is ok to mount on my REBEL T2i camera? Im afraid it might fry my
camera if I do, so if anyone knows please, let me know. Thank you, so much.

When mating a flash to a camera there are two things to be aware of.
1. Trigger voltage - does it exceed what the camera can safely handle?
2. Camera-specific flash dedication - Is the flash designed to mate with the flash contacts for a particular camera brand or model? If it is a "generic" flash that is not dedicated to a particular camera brand, then there is no issue. If the flash is designed to work with (for instance) Nikon's I-TTL system, then the multiple contacts on the bottom of the flash could cause problems with camera's of another brand - even, possibly, to the extent of causing electrical damage.

As far as #1 is concerned, do an Internet search for "strobe trigger voltage" and check out the results. Hopefully you can find both your flash and your camera listed. Note that several sites warn that they are posting information provided by others that has not been verified. However, you can also find links to the procedures to use so that you can measure the trigger voltage of your own flash. (For myself, if I didn't have information from the manufacturer, I would want to do my own testing rather than trust somebody else - but that is just me.)

If you have an issue in category #2, you may be able to use something like the Wein Safe Sync between the flash and the camera. Or you might be able to use the flash with a "dumb" flash cord that connects only the ground and the trigger contact, or some sort of wireless flash trigger.

Good luck,
