It's a Vivitar "auto thyristor" 2800 autoflash. It has a bunch of numbers i have no clue about what they mean. No maunals online. I'm amazed that Vivitar even still makes these, sine the one i have i got from some of my mom's old stuff, probably originally purchased pre-'85. Anyways, i've never used an aoutoflash so if anybody could help me i would really appreciate it. I can figure out the F row means stops. Though i don't even know why that would be on an external flash. here's a couple pics

the top line is the ASA speed ... so ISO speed ... the smaller the number the less sensitive the film the more light is needed in low light conidtions

i cant read the rest of the numbers
why dont you google and see if there is a manual
 
When you slide the tab over to what ISO you are going to use, the numbers next to the "F" slide too. What this is, is a rough guide to the effective distance of the flash based on your "F" stop.

So using that as an example, you're showing us that it is set to ISO 50. With that, the effective range at "F" 1.4 would be 40 feet, or 12 meters, following the numbers below the F 1.4.

DIN is just a different unit of ISO measurement.

Be careful with sticking that on a new camera though. The voltages may not match up, you don't want to fry your new baby... now do you? :)

Good point, considering he didn't say what he was going to use it on. If it is used on the original equipment it was purchased with, it should be fine. :eek: HOWEVER :eek: it apparently is a very bad idea to use it on many cameras. It has a max measured rating of 170V for trigger. Kiss any new camera goodbye the first time you use it. :D


Simple to use non-dedicated flashes aren't much to buy new now, so if you're in need of one, check out something along the lines of a new Sunpak 383 for about $70. http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=52799&is=REG

I bought one for my FZ10, along with the Omni-bounce (definitely spreads out the flash quite well) and have never been happier with the camera. It really makes the camera much more useful.
