Hello All,
I picked up the above flash at a Thrift Shop and it appears to be a great flash. Nice rotational features, well built and strong flash. This flash can be fitted to an variety of camera bodies by changing out the shoe module. The previous owner was using this with A Minolta Maxxum 300si film camera employing the Minolta/Sony shoe. My Sony Alpha 350 has the same shoe but this is a digital camera. I shot a few images and get varying exposures with the same setting, same object, same distance, etc.

I cannot find much info on this flash, no manual. I do not know if this flash was originally designed for use on a film camera and not compatible with digital or ????? Yesterday, I read an article that non digital intended flashes do not use the pre-pulse associated with digital cameras and may not properly synch. I have no idea if this is an obstacle.

I would like to use this flash off-camera as a side light for portraiture and trigger it by another flash.

If anyone knows this product, has comments, or manual, help, I would be most appreciative hearing from you. I think this flash is about a 2000 vintage.

Thx,
Larry

Larry, My concern would be the trigger voltage of that flash frying the electronics of a digital camera if that flash was designed for film cameras.

Normally you don’t use an flash from the film area on a digital camera-you will damage the camera. But Sony bought Minolta- who knows what they use from Minolta.......

I use a lot of old flashes and they work well for me however the one you mentioned is one that I can't make it work right. Doesn't harm my camera though it simply doesn't work right.

This flash is from the pre-digital era. Different dedicated modules for Canon A-family, Nikon, Minolta, etc. I have two of them with Canon and Nikon modules.
Trigger voltage is 5 volts or less....safe for digital cameras.

You are correct on the voltage. I have found a bit more information since this post. The voltage is safe. Thank you for your reply.
