Received an defective item listed as Excellent
I purchased a Sigma APO DX DG TeleConverter specially for a lens that I have. The TC was shipped quickly and I received it quickly, It was graded as excellent, and sure enough it looked very good visually. However, the electronics are defective and was obviously not tested before the item was listed. So I now have a TC which cannot be used for the purpose I bought it. No AF or AE information available. This is rather annoying, because I paid for expensive shipping overseas.
