| Re: Manual Focus Nikon Glass |
My latest engineering job - converted to Ai and its predecessor. Each of these images was taken with the other lens wide open.
The "S' lens was a four(4)-group, six(6)-element Gaussian type with an additional weak concave element at the front, for a so-called retrofocus type lens of seven(7)-element construction.
The "H" lens This lens went on the market five(5) years after the Nikkor-S, with a new optical configuration - a four(4)-group six(6)-element orthodox Gaussian type.
With advances in optical design technology, a Gaussian type optical system was now capable of providing adequate back focus for the design of a 50mm lens.

Both lenses are great to use with the "H" having the edge over the "S" (in my opinion) but its hard to see.
