does anyone know what flash this is.

a friend at school gave me a flash to see if it works on my camera (rebel xt), it did work in auto mode but i dont know how to work it in manual. ive have no knowledge of flashes this is my 1st one if i can use it on my camera. i noticed that the connection on my camera has like 5 spots on it where it seems something should be connecting to it, on the flash there is only one which matches up with the biggest spot on the camera, im wondering if it is cause nothing is touching the 4 other spots that maybe this flash is not for this camera. can anyone help. also the pic i took in auto mode was real bright how to you control it.

I don't know much about flash as I am just got me one recently, but I think I would be careful just putting any old flash on your camera. Seems I have read you can damage it due to different voltages etc. Someone more experienced can correct me if I am wrong.

It looks like a Sunpak (brand) unit of some sort. Are there any controls on the back? Can you show us a picture of the back of the unit? Is there a model number on it anywhere?

From what I can tell, it's an old-fashioned non-dedicated flash. It will work with your camera if you set your aperture and ISO to match the distance on the chart, and set your shutter speed at 1/200 or slower.

According to the chart on the flash, this unit has a guide number of 64 feet, which is only about a stop better than the built-in flash on your camera.

You might want to measure the trigger voltage. More info on that here.

wow, ok thanks, guess i better find out what flash it is b4 i try and play with it again, cant afford to mess up my camera.

the controls on the back is just a sticker with 0 degres thru to 90 degres, im guessing that you can rotate the flash up to 90 to bouce off the ceiling and 0 would be pointed straight ahead, the pic i posted has everything that has lettering or stickers, just 2 blue circles one on each side where it rotates from 0-90 degres and the stuff on top nothing on the back at all. i can take more pics if it helps, what angle do you want. it takes 2 double A batteries if that helps. do you think this flash will mess up my camera?

From what I can tell, this is a manual flash. You would need to estimate your distance to subject, then select an aperture/ISO combination from the chart. For example, if your subject is 16 feet away, you would use ISO 100 and f/4, or ISO 200 and f/5.6, or ISO 400 and f/8.

But the chart won't be useful if you bounce the flash, so I'm still a little perplexed.

The web page I linked to above has instructions on how to measure the trigger voltage. Since it appears to have no auto mode and is only marginally more powerful than your built-in flash, I don't think this unit would be very useful on your camera.

that sucks thought i had a freebie, thanks for the info.

Flip it over and show us what the other side looks like.
