You might want to look at something less expensive. The cheap Chinese units found on eBay run at about 1% of the cost of a Novoflex adapter (range of around $ 1 - $2 versus $100 - $200).
What the adapter do is correct the lens to sensor distance between the two systems, so the offset you are seeing is going to occur unless the manufacturer has taken the time to thread the adapter to line up properly. There will be no difference in lens performance.
