20 Most Recent Sunpak Auto 221d Flash - For Canon Film Cameras Questions & Answers


No. The flash's trigger voltage is much too high. You could use something like this to isolate the units, however you won't get any of the automatic functions.

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.

Have you tried other flashguns ? Does this unit work on test ?

I think you would need to send it for repair but be aware of the cost of repair as apposed to a new unit.

Yes you can. All you need is a small inexpensive slave unit.

I found this for a Sunpak flash which is similar to the G4500dx: Reading from the "auto555/G4500DX" Manual, you need to: 1. Slide the Film Selector to desired ISO - (that is the same as your camera ISO used - so, make sure you turn Off the Auto ISO feature if your camera has one). 2. Slide the Mode Selector to "A" (Auto position). This will be Auto Thyristor mode on the flash. 3. Slide the Auto F/stop Selecct Know to desired lens openning - ( so use your camera in Aperture priority mode, more in Manual to prevent changes in the camera aperture value during shooting) Shoot, and be happy with well exposed pictures by the Auto Thyristor features of the Sunpak 555 flash. The Sunpak 555 works great with Nikon D50, D70 cameras, as you can synchrinize flash practically at all shutter speeds. Excellent for sunny days to get narrow DOF, yet get any ambient light level contribution as desired. For other cameras, make sure (watch out for) that Aperture Priority mode does not use shutter faster than the camera max X-sync speed - so Manual camera mode could be a better choice for a novice photographer. In the manual there is also a list of accessories for various brand cameras, How to use Power Ratio in Manual mode, some advice on using wide lenses, how to care of your 555, and Specification section. Minimal flash duration is 1/450 at full power, so you can safely use Auto Aperture up to 1/500 sec. Flash duration decreases with lower power setting, or lower auto mode need for poser, and the shortest flash duration is 1/17000th sec.

These are not that expensive to buy, the problem is that the parts and service are more than a new one. In any case they use high voltage and you have to use special tools to measure and service the flash circuit. IT might be the flash tube is bad, the trigger circuit is bad, the capacitor is bad etc.

My sunpak digiflash 3000 will not flash at all even when pushing test button. It warms up, ready light comes on but no flash.
