The classic Nikon Lens on Sony A7 - Nikkor 35mm f/2.5

It is a Nikonos 35mm lens.  And behind this lens it has a very interesting story.  The first generation of Nikonos indeed is not the invention from Nikon.  "Calypso" is the original name of this camera and Nikon took over the producti around 1960.  It was not right to let the Calypso using non-Nikon lens (Calyso uses SOM Berthiot and Angénieux lenses). So Nikon chose the w-nikkor 3.5cm f/2.5 which was used on Nikon SP camera. The latest version of w-nikkor 35mm (3.5cm) f/2.5 has multi-coating.

Using Nikonos 35mm on Sony A7 is simple. However, it is better to remove the front cover glass which causes "haze-like" and yellowish image.

It is a very good lens on Sony A7x camera and  better than the Contax T 38mm.
