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.

Need manual for sigma ef-500 dg super minolta version


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.

Sigma ef-500 dg st won't work with my d300 or 200 in ttl mode


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.

Flash will not fire. Light indacts if fired, but no flash. Good contact and fresh batteries.


Hi Tam,

Try this:

Flash ready.
Short out center pin to outside contact..this will fire the flash.

Sigma EF-500-DG, does not charge and does not become ready


Hello

Thank you for using FixYa for your problem

Always check the batteries first - make sure they have full charge (in the wrong way can discharge them) but if is it still giving the same fault, your flash is faulty.
It should be taken to an authorized repair centre for a repair estimate. Very few digital cameras have any user-serviceable parts.

Please rate our solutions and if you still have problems please call back for more ideas to help you

Thanks
