Jupiter-11 135 mm f/ 4 M39 SLR Lens

The Jupiter-11 135 mm f/ 4 (Russian: "Юпитер") is a medium prime  tele lens with a single-layer coating for film SLR cameras with the m39 screw mount.

The export variant of the lens was named the Jupiter-11,135/4

Real focal length: 133 mm

The lens is a Soviet replica of the German Carl Zeiss Jena Sonnar T 135 mm f/ 4

The version with the changeable Jupiter-11A mount was also produced.

The Jupiter-11,135 mm  f/ 4 is characterized with a very compact size,  with a nice Sonnar blur of confusion zones (mainly due to the 11-blade iris aperture), rather good resolution and contrast.

It was also produced for rangefinder cameras. This variant of the lens  will be discussed in a separate review.

The Jupiter-11 is fit for portrait and fragment photography, for artistic photography of various genres.

It looks very well on mirrorless cameras.
