Sunpak 2000 DZ

There is no video mode on the Xti. The first Canon Digital Rebel to be equipped with video was the T1i, which came out almost 5 years later (2 years ago).

Hi,

Try this:

No. You will need an EX series flash like the 430EX or 580EX. Those designated as EX II will also work.

Regarding using the Sunpak 4000AF flash with my Canon EOS Digital Rebel, I can't get the flash to fire. There seems to be no combinations of settings that works to make the flash work. Could a weak battery in the Canon cause this? Does it require some other wire connector between the flash and the camera?

I know this is old technology now, I have a pocket digital for most of my uses, but I'd like to try bounce flash again on my old Rebel digital, and so I've gotten out my old camera and the flash I had bought for it. I had bought the Sunpak flash years ago and I honestly don't remember if I got it to work back then or not.

Thanks for any advice.

I contacted Canon technical services through email. Then we uninstalled everything and reinstalled an it worked!

The Rebel XTi has a sophisticated communication protocol between the camera and a dedicated flash. Only ETTL-II capable flashes can benefit from all the features the engineers at Canon thougt out. This means that with the otherwise superb Sunpak you won't be able to emit autofocus assist pulses, red-eye reduction pulses, the camera won't increase or reduce the flash intensity for bracketing, zoom lens settings won't be reflecting on the flash illumination angle, and so on. But! Set your Canon to full manual (125th sec), set Sunpak to auto, take one of the working apertures according to your taste (depth of field, etc.) and set the same aperture on the camera, and shoot. You still can use bounce flash. I am not sure about second curtain flash, I suspect it won't be possible. Both tele kit and milky filter in front of the flash head are of great help, you don't need to worry about the differences these make in flash intensity. Always keep in mind that the flash makes good exposure according to the given working aperture and, as long as you set the same aperture on the camera, the subject will be correctly illuminated. (I have a Sunpak 522 and a 455 and employ them this way, with success, on my XSi.) Of course you can set set the flash in full manual (M/PR/MD), using the left side, set knob and calculator dial, and this is the only way if you want to make series of shots, because the flash can only make bursts if the power is reduced to at least 1/16th. Good light, Laszlo

Your battery is low ...shut the camera in off position and replace with fresh battery

if it is an auto focus lens that works on one eos camera, it should work on almost all of them. the only known exception is that some high end extenders will not fit the eos1dmarkII as it protrudes into the opening too far.
but a good rule is that if it fits without any obstruction issues, it should work. try cleaning contacts on the lens and camera body. if that doesn't fix it, talk to Tamron. you can use it manually, but will not be as easy and you would get less predictable results.

my suggestion is to always go with lens from camera maker.

sounds like there is an issue with the tamron lens. not the camera.
good luck

Most DSLR cameras (like your Canon) don't have a live view - in other words, you can't "see" the image before you capture it. You must use the viewfinder.

at a whopping 46.6V.. yes, it would damage it.
