So I'm a fucking idiot and ordered used Sigma MC-11 converter online for my Sony a7riii camera for EF lenses from my older system, but had no idea it comes in two variations under the same name - for Canon EF and Sigma SA lenses.
Of course I recieved a wrong one - for SA mount lenses, and can't refund it.

I already bought the EF one too, so my question is:

Are there any good and cheap Sigma SA lenses that are worth keeping the converter for them, or I shouldn't bother and just try and resell it?
