    This is another "Rodney Dangerfield I don't get no respect" lens. Everyone talks about the 3.5cm F1.8, wich typically goes in the $1500 range in Leica Mount and ~$1,000 in S-Mount.

    This Leica mount version of the 3.5cm F2.5 ran $300, and the S-Mount version was ~$250.

    These are 6 element in 4 group Planar type lenses, same as the 35mm Summarex. I find the Nikkor optics to be just as sharp as the Leica lens, and the contrast to be higher. The Leica mount lens is tiny, uses 34.5mm thread mount filters. This is a hard size to find; I wrap a layer of nylon tape around the threads of a 34mm filter and use it.

    Wide-Open, the SR-71. Bokeh is not as smooth as the 35/1.7 Ultron- a lens that uses aspherical optics to reduce spherical aberration. The Nikkor 3.5cm F2.5 and 3.5cm F1.8 are over-corrected for spherical aberration- busier out of focus areas when used at the extreme. The F2.5 lens uses a "flowering" aperture similar to the Zeiss Opton 50/1.5 Sonnar and modern Sonnar to reduce focus shift.

    Wide-open

    This image gives the illusion of "3-D", I've taken pictures of this F-86 with a lot of lenses. The Nikkor 3.5cm F2.5 "has something" to it! This is stopped down a little.

    I have the 3.5cm F1.8 in S-Mount, a good user picked up for $400. It has a 1-stop advantage over the F2.5 version. My 35/1.7 Ultron AND the 3.5cm F2.5 cost me less than half the F1.8 Nikkor. i'm happy.

    this is a tremendously underrated lens. its the sharpest smallest $300 lens i ever owned. excellent contrast and color for an old timer. i should never have sold it.
