Period of use: 3 months

  • Low Price: 15 euros
  • All metal
  • 15 diaphragm blades
  • Preset aperture system (I like them a lot)
  • Sharp at f/5.6
  • Nice color rendition
  • Long focusing ring rotation
  • Very easy to disassamble, clean, repair...


  • My copy suffered from stiff focus, solved by cleaning the helicoid and applying new grease
  • Not a fast lens (f/4)
  • Soft at f/4, you have to stop down the lens a bit
  • Long minimum focusing distances (>1.1meters)
  • Heavy and long
  • Difficult to nail focus if used on a DSLR


To be honest my expectations where very low for a 15 euro lens that needed cleaning. After cleaning the helicoid and aplying new grease it is easier to handle but still stiff.

Not a really sharp lens at maximum aperture (f/4), but fine if stopped down one o two steps.

It's 15 aperture blade system help to mantain a round shaped higlights.

Color is ok for such an old lens, a bit less warmer than my Canons and more closer to my Nikons.

As DSLR user I cannot recommend this lens as it is very difficult to nail the focus using the optical viewfinder, a lens with wider aperture (f/2.8 for example) is easier to handle than this f/4.

If you wanted a cheap vintage manual focus lens under 50 euros this is the lens you where looking for, but a 135mm f/2.8 will be more interesting than this f/4. And 135mm f/2.8 are very common.
