Meyer-Optik Gorlitz 1.8/50 Oreston lens review (Meyer-Optik Gorlitz 50mm 1:1.8 Oreston)

Mount – M42

This lens is far beyond my interests, I don’t know anything about it, except that some photographers call it as “bokeh-monster”, so instead of the usual short introduction and a little story about the history of the lens, I’ll just leave a link to the wiki.

The lens for the test was provided by Egor Nikolaev (Егор Николаев) – many thanks and greetings.

Сlose-distance resolution test, minimal distance

Testing methods description

  • Target: 10-15 cm picture, printed on glossy photo paper
  • Distance: 1.7m
  • Camera: Sony A7II (24mpx, full-frame, tripod, remote control). M-mode, ISO fixed, WB fixed, SteadyShot – OFF.
  • The test was repeated for every F-stop on every focus position with manual focus adjustment for each shot. That is to avoid the effect of field curvature.
  • RAW processing: Capture One, default settings. All quality settings – 100%. Crops – 300×200 px

Meyer-Optik Gorlitz 50mm 1:1.8 Oreston – final conclusion

This time the conclusion will be pretty short: this lens has a bad IQ. We can see enough big aberrations, too much softness on apertures up to F4, even geometry is not so good as it can be. Many other cheap fifties from that period of time are able to provide much better performance. On the other hand, it is possible that if a photographer needs some kind of special bokeh, which tends to be “swirly” or “bubbles”, then it should be considered as an option, but the price in term of sharpness looks too high. Anyway, no recommendations – too many competitors with definitely better results in IQ and probably in bokeh.
