I have used my 15 years old VIVITAR285 ZOOM THYRISTOR flash on many SLRs including my CANON EOS Elan 2, it has consistently out-performed my SPEEDLIGHT 420ex in terms of zoom coverage and exposure. I think it to be the best semi-auto 3rd party flash ever made. On some web forums its trigger voltage was described as a big "con" for using it on AF SLRs for it could "fry" the modern SLRs circuits. Well it never happened to me, but some-one advised me "it doesn't mean it (frying) will never happen to you".

Having elaborated that back-ground, i have ordered F-10 after thoughtful comparison with CAnon G5, Nikon 5700, and Olympus c-5060. One big reason for the order is f-10's 3rd party flash acceptence. I haven't received the box yet and i am asking for any experiance/recommendations regarding its use with VIV 285. I read some where that the f-10's hot shoe can safely handeltrigger volts up 24DCV, if that is correct, i think in theory i will be able to mount VIV285 on its (F10)top 'cause i ve been doing this with Elan2frequentlywhich reportedly permits trigger volts of only 6DCV.......

I read people playing with SUNPAK383 on F-10 and i assume the VIV 285 would live the same way.....but no rooms for assumptions with a USD 500 OUT_CLASS DGCAM...

I have the Vivitar 285 HV that I use with my FZ10 and it works great. I think there is a differfence in the volvage between the 285 and the 285 HV. The HV has been out for a number of years so you may want to check it out.

Zaheer, you can measure the trigger voltage yourself, just switch the flash on and wait untill it's ready. Now you can measure the voltage with a digital multimeter on the flash' hot shoe contacts. Middle contact is +. Some older Vivitars have trigger voltages up to 500 volt!

The Sunpak 383 can be safely used with the FZ10, it's trigger voltage has been measured between 3 and 10 volt.

:cool:, getting sunpack 383 then :)
can't wait... :D

This suggests you might have too high a voltage on the 285:

I got a 285 HV for the extra range of the zoom. It is a bit bulky but works fine.
