Yup ... the Vivitar 283 does draw quite a load and can do damage. However, WEIN makes a unit (their HSHS) that keeps this safe. I believe I got mine at B&H. Sandy F.

Excuse me if I bother you again, however I'd like to share the first photo I took using the "new" flash, it was taken with the 3.5F Planar and the flash attached to the Rollei Pistol Grip, it's the first photograph in the blog: http://www.itarfoto.blogspot.com/ All the best Carlos Hi, Nice shot- I've been using a 283 since they were first introduced more than 20 years ago. I remember waiting for the package to arrive in the mail. I have the wide angle and tele adapters, as well as the off-camera sensor, which are useful for some situations, but not when you have to have a flash ready when you are on the run. The concern I have with mine is that it has a very high terminal voltage and draws a lot of current across the flash contacts. I've used it with several cameras, including a 3.5F and haven't noticed any damage. I believe that later versions included some provision to limit the voltage and/or peak contact current.
