Wein 990-560 Overview

The Wein Safe-Sync Hot Shoe to Hot Shoe regulates and reduces the flash sync voltage of the flash from up to 400V to less than 6V. This is especially important for current automated SLRs or digital cameras when used with older flashes or lighting systems.

This model mounts directly to a camera's hot shoe and provides a hot shoe on top and a PC female flash connection on the side.  You can have a flash connected to the hot shoe and a flash being triggered by the PC female connection-and unlike so many other offerings of this type, both will fire simultaneously from the same signal. The exception to this rule pertains when using 1 or 2 flashes that are already under 5V sync voltage. In this case, the flash or flashes will not fire.

Poor design choices

By Mark
Rated 2 out of 5
Date: 2025-03-07

This product has three issues. First: the quality control for this product is not good. Purchased one that was flat out broken from the get go. Solder was shorting out components. Returned the product for another unit and this one did work. There were two design issues I would like to highlight. The first is the oversized PC Sync port which they proudly proclaim is oversized for our benefit. The port is so oversized that you must dedicate cables to only be used with this voltage isolator because it bends the PC connector so much that it is loose on any other PC port. The second issue is in my opinion a larger problem and that is that the inside female receiver for the PC cable pin can rotate within the housing which means that with a couple of accidental spins of the cable you can break the solder connection to the PC port and brick the unit. You can get in and re-solder the connection but that is assuming you have the knowledge equipment and patience to do so.

Safety with old flashes

Allows use of old, high voltage, electronic flashes with digital cameras. It is built like a tank and works exactly as advertised. Offers both hotshoe and pc connections. Highly recommended.

question

I have one of these that I used with a Nikon coolpix 8700 and an old Vivitar 283 flash. It worked great. But it won't slide into the hot shoe of my Nikon 7100. Why not? Can I safely use my Vivitar 283 with my 7100 if I can get it into the shoe?
Asked by: Anonymous
The Wein Safe-Sync Hot Shoe to Hot Shoe mounts directly into standard hot shoes such as the one on the Nikon D7100. You will safely be able to use the Vivitar 283 with the D7100 using this device.

question

1/ Is this product's trigger voltage safe for my Pentax K10?2/ Will my Vivitar 273 thrystor be safe to use with the Wein product and my K10, and will the flash synchronize with K10 automatic mode?thanks
Asked by: Anonymous
The Wein Safe Sync Hot Shoe to Hot Shoe will allow you use your older flash on top of your Pentax K10. It will reduce the trigger voltage to a safe voltage to use with the camera. As for the mode that the flash would trigger at, that would be dependent on the exposure mode that is set on the camera.

Will this work with a Vivitar 273 or Olympus T32 and a Olympus OMD EM1 mk2?
Asked by: Keith
This would work with those cameras but not for TTL, you would have to adjust the power manually but it will fire them.

question

Is this product compatible with the Sony A7 mirrorless camera? I'm interested in using it on the A7 for studio photography. Thank you!
Asked by: Anonymous
The Sony Multi-interface shoe is a bit unique compared to other standard ISO shoes used by other brands. This safe sync should fit onto the camera's hot shoe and function, however on occasion there are 3rd party accessories like this which have trouble lining up the center pin for contact to fire. If you purchase this and it does not fit/function well for you, you may return it within 30 days of the original purchase.

question

will this work with a Pixel Straight Sync Cord with 1/4 inch Mono Plug to PC
Asked by: Anonymous
That is a hotshoe adapter and it will work with a male PC sync cord. The other end does not matter.
