Even if they focus correctly they get around poor design and finish by brute force - meaning that you're putting undue stresses on your expensive lenses each time you put a lens on or take it off.
I bought a Novoflex to hold my precious Zeiss glass to my Nex 7 and it works great. Having bought a cheap Leica adapter and a dozen issues I have just ordered the Novoflex Nex/Lem.
PS - the cheap one wouldn't focus on anything past 20-ft.
I'll be just as hard on the Novoflex if it doesn't come through.
