20 Most Recent Sunpak PZ 4000AF for Canon TTL Flash Questions & Answers

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.

The Sunpak PZ 4000 and 5000 were made for film cameras. I have one for my EOS film cameras. It works just fine. I know this series of flashes was not made for the digital cameras. It likely will not harm your camera if the flash is designed for your camera brand. But some functions will not work.
For example, do not use a flash for Minolta on a Nikon.
You risk damaging your cameras electronics or frying the flash.
Get their PZ 20, PZ 30, PZ40 or PZ 42X for your digital camera.

Canon digital uses E-TTL metering for best flash results, the older Sunpak unit isn't compatible with this, so it is not fully compatible. It may work in manual mode - but won't be as good as a more modern compatible digital flash like the Canon or Metz (eg 58AF1 Canon) versions.

The Metz 40AF -4 is similar. You can download the manual from http://www.metz.de/en/photo-electronics/instruction-manuals/mecablitz.html (the manual is for Nikon, but I do not think it matters).

Good luck

The Alpha 100 only supports pre-flash TTL and ADI flash control which are not supported by the Sunpak. The flash should ignite, but automatic controlling of its brightness is not possible.

For more Information about the different Minolta/Sony Flash Metering modes cf. http://www.mhohner.de/sony-minolta/flashcomp_mm.php

probably in MANUAL mode only.... my Nikon and Canon's work with the pz4000 (at a save trip voltage I may add) but in a manual mode as mentioned above.....

Hey there, I had one a couple of months back, but unfortunately I got rid of it since I no longer use it. But, you can certainly buy one online. Check out Amazon or Newegg. Good luck!

When it is not triggering either Tube is dead or Trigger circuit has a problem. You can get junk flash from Ebay.

This should be covered in the manual - it is probably an error message of some description.
