Sony alpha 350

You may download a copy of the manual from here. It's for the Pentax version of the flash, but I don't see anything in it that's Pentax-specific except for the mention that's it's Pentax-specific.

Unfortunately, the manual for this model is no longer available online (even on the Sigma website). Try searching torrent sites and ebay as a last resort.

this flash is not compatible with the d200. i had one and sent it back to sigma, they upgraded the software in the flash for free. now it works in all modes, it needs to be iTTL to work on the nikon d200 the NAd version is not iTTL.

This Sigma flash is not Ittl compatible. The D300 and D200 Nikon must have Ittl compatible flash to operate in any of the Automatic modes. It is a great flash but will not work on those two cameras.

with the flash on, I would think most pictures would be bright white. Try turning the flash off, use a different setting than P.

Yes, if it has a Minolta/Sony mount. The Sigma EF 500 has been producedin different mount, so that the model can fit different cameras from different producers. A Sigma flash for Sony should have SO-ADI written on it.

A: For Sigma issue:

The Sigma EF-500 flashes have very small chromed contacts for the batteries. Even though they may not look corroded, they may not power up or conduct enough power to fully cycle up. Use a polishing tip in a dremel or an ink eraser tip to clean the internal wire contacts and the flat contacts on the door. I use dielectric grease on a q-tip to apply a coat to all contacts and cleaned battery terminals to minimise future issues.

If it is a dynax compatable lens it should work The really old 75-300 shiny black finish will not work
and can not be rechiped

I had the same thing happen. Sent it into Sigma, they replaced it for 50 bucks.

send it to a sigma agent thay can replace the broken part
