I have a Sunpak auto 622 pro system flash. I put this on the shelf about twenty years ago and it was working perfect. I now want to use it with my Olympus E520. The flash seems to work OK except the auto exposure doesn't operate correctly. All my pictures are way over exposed. My conformation light does not come on. Do you think it needs a good cleaning or what? About what would servicing cost to correct such a problem? Thank you. Respectfully, Richard

SOURCE: I have a sunpak 622

Sunpak does not offer dedicated (TTL) module to any digital cameras. The flash can only be used in auto mode, while the camera is set to full manual. The lens has to be stopped down according the working aperture on the flash, correct exposure will be maintained by the built-in sensor of the flash. Fire the flash using a simple hotshoe-to-PC cube if your camera doesn't sport a PC connector. Trigger voltage of the 622 is safe.

$ 111.00 to look and additional for parts and labor. Expensive.
Probably cheaper to buy one off eBay.

SOURCE: Sunpak 622 Recycle Time w/ Batteries vs AD-26

I had the same problem - 10-11 secs on 240VAC. My solution was to get the Quantum Turbo SC for $450. It yields ~3sec recycle times. This pack for $150 should play nicely as well: http://www.adorama.com/JTMBPN.html?searchinfo=jtl+lancer+battery+pck It was out of stock at the time. The Sunpak TR2000 is $250, but it's Ni-Cd while the others are NiMH. There are other HV packs capable of powering the 622 w/ the fitting cable like Lumedyne IIRC. The AD-26 is still useful for non-action photography. The fastest time I saw posted is 1.5 secs, but it's a DIY job (search 'sunpak 622' on flickr). HTH,

Sunpak TR-Pak II a NiCad flash battery pack with charger and Quantam battery both has cords for 622.
Personally I have taken out wire pair from removable battery pack of 622 and connected to 4 cells of Nicd type D battery pack made at home.(I placed that in my belt bag).

I have read reports of this working. To be safe you can cover everything but the center pin with electrical tape, or you can buy surge protectors for flashes to protect your camera.
