Minolta sigma ef-430 st ma flash will not work on cactus v2

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.

If you're worried about the trigger voltage, that's not a problem. However, you may not get all the features you'd get with a more modern Nikon flash.

The trigger voltage of the Sigma EF 430 is safe for use with the Nikon D200.

Do you mean the EF 430? If so, then yes, it is compatible with the D60 and D7000, at least as far as the flash trigger voltage is concerned. You may not get all the capabilities of more recent Nikon flashes, but it will work.

Yes.

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 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.

I have a sigma EF 500 ST flash guns which I bought with nikon F75 some years ago. Would this flash work with canon 500d

Check the trigger voltage first.

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.
