Can Vivitar 285 (non HV) be used with K-5IIs?

I have an old Vivitar 285 (not HV) in very fine condition and would like to use it with my new K-5IIs. I have read many articles which cautions use of the flash with my camera because of "high trigger voltage" and only to use it in an "off-camera" configuration. I need suggestions on what accessories to purchase. Is a flash bracket (probably not the correct terminology) and sync cord all that is needed? Can a hot shoe adapter be purchased so the flash can remain on the camera? Any assistance or suggestions are highly appreciated!

Have you checked the voltage yourself? There are some 285s that are safe, the design seemed to change a lot over the years.

If the voltage is high you can use it with a Wein Safe-Sync on the camera, that will protect the camera from the high voltage. You'd also need this if you wanted to use it with a cable and bracket, since the flash would still be directly connected to the camera.

Another option is radio triggers, I know the Cactus V5 triggers are able to handle up to 300V, so the flash will not hurt them.

Agree, using an adapter or a sync cord will not protect the camera as the voltage just goes through the wires or adapter. Only wireless triggers will protect you or the safe-Sync mentioned above.

The best thing is to check the voltage yourself.

As stated in other posts, measure the voltage on the particular unit. The 285HV is safe, but the 285 may or may not. I had 3 copies of 283, one measured 10.2V and the other two some where around 180V.

IMHO, unless you have a specific reason to use a particular flash, a Wein Safe-Sync in general does not make economic sense. You can get a decent used flash with safe voltage for about the same amount of money for a Safe-Sync.
