Canon EOS 350D with SMC Takumar 2/55mm

Veijo Vilva

(Page under Construction)

  • FOV corresponds to a 88mm lens on a 35mm camera

  • a very sharp lens
  • very good multicoating
  • very high quality, all metal construction (except the rubberized focusing ring)
  • very smooth focusing

  • the lens is mounted with an M42-to-EOS adapter
  • manual focus
  • AV (aperture priority) or M (manual)


  • my test procedure isn't very rigorous
  • bad results may be caused by bad focusing as manual focusing in dim lighting isn't any too easy when the DOF for this level of expected sharpness is just a few millimeters in either direction
  • the backs of the books aren't at exactly the same depth, the maximum difference is about one inch. Only a few books at the center and at the upper right-hand corner have been aligned - roughly.
  • the test only shows that the specific tested lens is at least as good as my results -- even that individual lens might be better, and others of the same make and model may be better or worse
  • anyhow, the equivalent magnification of the 100% crops is just plain sick, i.e. about 48x on a typical 17", 1024x768 CRT. Normally, 8x has been considered a reasonable maximum for critical sharpness from film. At 48x magnification, a 35mm film frame would be about 172cm (68") wide, and even a 1.6x crop factor dSLR frame would be 107cm (42") wide!

Nothing Wrong with the Sharpness (Full-size) (f/5.6, 0.4s, tripod-mounted, remote release)
(Quite good, even compared with the extremely good Carl Zeiss Sonnar 2.8/85 T*)

A crop:

Note the cloth texture of the book in the middle, the width of the back is 20mm

A crop from the upper right corner:

The sharpness seems quite uniform from corner to corner.

Note: All shots hand-held

Against light, not much lens flare (f/8, infinity focus) (Full-size)
(Note: there is a reflecting glass surface on the left, the soft section is a reflection.)

A crop:

A 100% crop
