645 adaptor to K mount.. Question.

I have a 645 to K mount adaptor which I got off eBay. Really cheap one. (under $50). I have used it with my 120mm 645 lens for macro but I am never happy with the quality on digital. Of course the lens is steller when used on 645 film so I am wondering if the adaptor could be at fault. It has no optical elements so I am a bit perplexed.
THanks in advance.
Nick

depends on how far you are stopping the lens down, even my FA*200mm f/4 ED [IF] Macro which is widely regarded as one of the best telephoto macro lenses in history produces abysmal results when it's stopped down to f/32.
