the voltage on the flash hot shoe contacts (center pin and rail connector) can be as high as 140V DC and this voltage is backfed into the camera through its hotshoe connector. There are adapters that can be bought that isolate this voltage that go between the flash and the camera, but different camera makers have different ratings for the flash voltage. My Vivitar 220 has 122 volts across the contacts from 4 AA batteries! Canon recommends nothing over 6v but Fuji says 60v and others dont say anything. SLR's used a mechanical trigger, modern digi cams use an electronic trigger. Also Digcams use electronic metering for exposure so they dont take into consideration the addition of another flash unless they do a preflash, TTL metering and the flash unit is capable of recharging in about 1/10th second. YOu may have to do some post processing or set the camera on manual to adjust the exposure.

This is a yes and no answer. I personally would not use his flash on any of my digital cameras due to not knowing the "Trigger Voltage" one shot out of this could fry the flash circuit board of my camera.
The flash will not TTL or i-TTL with the new flash systems nor will it synchronize properly. However yes you can use this flash as a slave (using a electronic photo cell as a trigger) it will fuse a full burst power and you need to adjust it near or away from the subject to adjust the amount of light. It can prove a real pain but it will flash just not from the camera unless you use a special WEIN accessory to restrict the trigger voltage BUT the WEIN is over $100.00 so why not just get a flash that work with the camera. You would need a Canon EX type flash something like the Canon 420 EX II will be fully compatible with the new T2i.

You don't have to worry about a memory effect with lithium-ion batteries.
Before anyone can tell you whether a Sunpak flash would work with a digital camera, you'll have to tell us the model of the flash. You can try checking for yourself at
