A little differant twist, but similar. I love shooting a 28/3.5 Canon/Serenar. This lens lives on a Leica IIIG.
I seldom shoot wide open and use the DOF and scale focus to use this tiny rig as a point and shoot.
Adorama has a 28/3.5 Nikkor, but it is missing the infinity lock. They have had it for a while (more than six months). If the infinity lock isn't an issue could be a good opportunity to make an offer.
