So I bought a SMC Pentax-A 645 Macro 120mm lens without realizing I needed an adapter to attach it to my Pentax DSLR K-70 body. Does anyone have any suggestions as to which adapter I need to buy and if so do you have a lead on a reliable seller?

Thanks

There are lots of cheap adapters out there, such as this one. I'd recommend going for a genuine Pentax one, though. You don't want your lens to wobble or risk falling off the adapter, after all...

This adapter is just a simple tube, so it boils down to the workmanship.
