Wein Hot Shoe To Hot Shoe Safe Sync (HSHSB) Question

I am thinking about buying a Wein safe sync and don't know which one to get.

My Rebel XTi has 4 pins and 1 larger button on the hotshoe, my Vivitar 283 Flash has one button in the center.

Which one do I need?

Thanks in advance --

Jim

The extra pins on your XTi are for the Canon ETTL to work. Using a shoe cord and shoe with only a hot and ground will manually fire your flash but you lose ETTL. I just learned about this myself.

Thanks,

My plan was to use the Wein on the hotshoe of my camera, and the flash on top of the Wein.

The guy says the Wein doesn't have any buttons?

I don't know anything about the particular device. Can you post a link to it?

Robert,

I finally had sense enough to do a search on the site, and found out that I don't want to use the Wein adapter, as I would have to use the flash in manual. Thanks for trying to help me --

You can use the 283 in auto; just set the camera to manual or Av, using the aperture the 283's computer dial tells you to use for the approx. distance and ISO in use. And you want just a straight hot shoe Safe Sync. Doesn't need the extra pins, only the main contact.

My Wein SafeSync has a test button and a PC plug. I use it with my Sunpak 555 although I inderstand it might not be necessary with that flash.

Jon,

Where do I find a straight hot shoe safe sync ?

This has all come about over using the Vivitar 283. I tested mine and it puts out 8 volts -- they say the max is 6 volts, and I don't want to ruin my new XTi.

Thanks.

My Sunpak 555 has a sync Voltage of only about 5 Volts, so a "Safe Sync" is not necessary for my particular unit.

There is additional info about other Sunpak 555 units on this site:

But, you should check yours to be sure. All you need is a simple Volt meter and about 1 minute of work.

Enjoy! Lon

Lon,

I checked mine with a voltmeter in the DC position between the center post and grounding strip, it reads 8 volts on my Korea made Vivitar 283. That 8 volt reading has also been verified by the Botzilla website for other Vivitar 283 Korea made units.

No one has assured me that the 8 volts would work OK on my Rebel Xti without hurting my camera. I've read that the voltage shouldn't exceed 6 volts that's why I was looking into the Wein safe sync -- I may not need it if the 2 volt difference was OK.

Thanks,

Jim

Yup, check it to be sure. My 555 was giving me readings in the 7~8 volt range and since it was going on my 300D I opted to go the safe route. Given the number of shots I took before I got the 20D it probably was over kill.
