[8ball]

Has any one used one of these?

I want an on camera flash but I am having trouble deciding what I want, I dont want to spend $100 I would like to stay in the $ 50 range I found one on google which I posted the name above please lead me in the right direction.
Does the one I posted above talk with the camera or is it completely manual.
Thank you!

The camera you have matters. You can get the old film thyristor auto flashes very cheap and they might work with your camera.

How to use an auto Thyristor flash with my DSLR

Saturday, 22 August 2009 23:08


First, have look on this topic to be sure your flash will be compatible with your DSLR.
You are certainly wondering how and why a 25 years old flash will be simple to use with a new DSLR?
The reason is very simple. These kind of flash also called Auto Thyristor or computer flash were able to perform the metering and then provide the required amout of light to get a good exposition.
The flash has to know the ISO setting of the camera, and the aperture setting. Then, using it's own light sensor, the flash will compute the flash power reduction required and the flash duration.
The only thing you have to manage on the DSLR is the shutter speed. You shall not exeed the maximun sync speed of your DSLR.
For the Sony A700 it is 1/250 without the steady shot enabled and 1/200 with the steady shot enabled.
Check your camera user guide to know the maximum sync speed not to exceed.
if you vastly exceed the maximum sync speed (e.g. 1/2000 for max sync speed of 1/250) the sensor..."
