The letter "A" in the name of the lens means that lens has a removable shank and can be installed to the other camera system (Nikon or Pentax).
This lens is also available in version with achromatic multi-coating - MC Jupiter-37A 135mm f3.5 (since 1980). MC version is much more resistant to the backlight. Contrast decrease and flare are almost unnoticeable.
There is also a version of this lens named "MC Jupiter-37AM 3.5/135". It is an upgraded version of the older lens "MC Jupiter-37A" which was being produced earlier. "MC Jupiter-37AM 3.5/135" differs from older version with higher reliability and lower weight because of it's design improvements.
Jupiter-37 135 / 3.5 lens was recalculated from Carl Zeiss Sonnar 135mm f/3.5 according mostly to the new types of glass used. In this case, the lens reconstruction was successful.
