Metabones adapters are not very good.

Victor,

I have had one bad Novoflex in the past 8 years...the original Leica M to m43 was unable to focus to infinity...they blew it...introduced a new one within a few months that was fine...I still have it.

At this point I have 5 Novoflex adapters including the Nikon G to E...which I used for recent posts on the fun with Sony A7r/A7 thread....Leitax 180, Nikon 105 F 2 DC and Zeiss ZF.2 50 Makro F2 all stunningly sharp....locked on tripod with mirror up but the adapter was fine.

I would suggest you return/complain and get a new sample.

I would use the N before almost any other adapter...except Leica brand...

The issue I had was very unusual in that both of my lenses had an abrupt out of focus area on the left side. I had never seen anything like it. Those same Zeiss lenses performed perfectly on my 800e. My point was/is that regardless of manufacturer nothing should be taken for granted and all of this stuff should be thoroughly tested. That said its good to hear the positive endorsements for Novoflex.

I had the same problem with the Novoflex M-> MFT adapter. It was a rather tight fit and i wasn't able to focus to infinity with the 90mm F2 Summicron. I had no problem with the 50mm F1.4. Given the cost of the Novoflex adapter i was quite deceived (250$).
