HEADS UP.
if your adapter and lens fit too loosely....
I was annoyed that my 50 was loose on the adapter, but there is an easy solution. The bayonet tabs on the adapter have a thin gap in them. Slide a small but strong pocket knife, or something similar, into the gap and rotate slightly. The lower metal is soft enough to flex downward and recreate a very snug fit for your lenses. Do with caution and blow out any possible metal shavings before mounting. Easy Day!
BTW, can't take credit for the solution. LuckyPenguin on another forum is the originator.
