I have a question, I have just recently bought a used sigma 18-35mm from a retailer for my canon 80d that stated it was for Nikon however I’ve done my research and know that the lens itself supports canon and certain other cameras with an APS-C sensor, by the retailer stating that the lens is for Nikon does that mean that I would need to buy a canon mount or no because I know it does give the option to choose what mounting you need between the two but I didn’t think in my case that it wouldn’t. Does anyone know the answer to this?
