Problem with the communications between my camera and lens, Canon eos m, Sigma 28-200mm macro lens and a viltrox EF-EOS M adapter

Recently I bought a Sigma 28-200mm lens for my canon eos m, it looks fine, no scratches wear etc, I then ordered a viltrox EF-EOS M adapter for my lens, I fitted everything together and now it says "Err 01 Communications between the camera and lens is faulty. Clean the lens contacts."

I then wiped down the lens contacts and the same error message keeps coming up, what should I do?

Thanks.IMG_20200703_182652.jpg

Can you return it? Problems with this lens are common from online forums I've seen. Its not worth repairing.

Auction places like ebay have a money back guarantee, or if a credit card was used and you were scammed, you can file a claim.

Try taking the lens to a camera shop and putting it on a Canon DSLR to see if it works there. Its possible that the adapter is bad, so it does not hurt to check.

I'm betting it is the adapter, not the lens. Way back when I had an M and bought a third party adapter for it. About half the time I got error messages trying to use Canon lenses. Upgraded to the Canon adapter and never had a problem since (using many different Canon lenses on the M, then M3 and now M5s).
