What does the wooble actually do? Is it just a 'play' issue? Is IQ affected?

I think Sean is overstating the case for adapter wear, no offense to Sean.  Properly designed and plated, Adapters should last a lifetime.  I think the problem that Sean is referring to is there are several cheap knockoffs that don't have the proper tolerances to start with.  The excellent thing about the Sigma MC-11 is its tight tolerances, i've used it a lot since i bought it in 2015 and its still tight.  Too much wobble and the electrical contacts can separate and crash cramera ops.  I had another mfr's adapter that i thought was getting loose.  Evetually found all 3 of the philips head screws were getting loose.  Retightened them and it was tight again.
