There is probably and adapter made because there are adapters for most anything. The question is, why. None of them work very well and that inclides the best of them. Right off, all automatic control is lost. No AE, no AF and they are likely inferior IQ to a modern EF or EF-S lens. Current DSLRs are not usere friendly to manual focus so this will be poor at best.
My advice, don't waste your money or time.
