For sale, Sigma EF-500 DG ST SA-STTL flash/speedlight for SIGMA dSLR cameras. This is not the version for Canon or Nikon cameras, TTL will not work and might damage your camera!!! Slight stain/discolouration on the flash and wide angle mask (see photos). Flash powers up and fires in manual mode, I don't have a Sigma camera to test TTL mode, was working last time I had a Sigma SD-14. Comes with box/instructions/stand. Sorry, no returns.
