I recently got one Nikkor S.C 5cm f1.4 lens. It took me three adapters to make it work on my Sony A7 - the Nikon-Leica thread mount, the LTM to M mount and the Leica M to Sony NEX mount. Not too difficult and lucky that the focus is still correct after the stack of adapters.
I have put other pictures at BigBigLens.com - Nikkor. I only started street photography a few month ago. I need critical comments.
