The test does not fully reveal the properties of the lenses due to technical reasons. The key reason is that the photos taken with these lenses were shot on a cropped MTF camera (crop 2.0).
Therefore, we won't see how much the lenses "smear" at the edges of the frame. However, we will still get some idea.

The photos were taken at 1 meter and infinity, with the aperture fully open, stopped down, and at f8.0.

You can download all these photos along with the RAW files via this link.

Unexpected findings:

  • The Nippon Kogaku Japan Nikkor-H.C, f2.0/50mm lens has a minimum focusing distance of 0.5 meters.
  • The modern Panasonic 1.7/25mm lens has significantly more chromatic aberrations than these manual lenses.
  • The Industar-26M has fewer aberrations than the Jupiter-3 (when fully open).
