In the contrary, you will hardly the notice the infinity focus problem. Many said it's spot on. I used to have a Nikkor 35/1.4 AIS and it did focus a little past infinity, but less so compared to my Zuiko.

Anyway, there is no such adapter available (due to the similar size of both mounts and little differences in registration distances). Usually you can mount the Nikkor directly onto the body. From the consensus, Pre-AI would fit snuggly, some AI and AIS can, some can't. Mount conversion is possible, though not all can be converted (depend on the construction of the rear mount). You might want to post your question over They have tons of DIY conversions and advices.

Good luck
