Tested lenses reviews:



Long distance – sharpness:

Test description: Camera Sony A7II (24mpx, full frame) was fixed on the tripod and managed remotely with computer display as a viewfinder. Targets (buildings) were fixed by gravity power on the distances in more than 200 meters. All shots were made with apertures from fully opened and up to F16. ISO-100. Shutter Speed – depends on light (camera A-mode). SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift.

Finally, pictures were converted from ARW-files in Capture One with default settings (some single files have a slight light correction, for better visual convenience in comparison), then cut into 300×200 px elements (100% crops), combined into diagrams and exported into JPEG-files.

  • Sunlight has been changed during the session.

‘What does it mean?’ – my conclusion:

I love such battles – where every of fighters don’t give up. Here you can see enough unusual case:

  • Center – both are similar
  • Middle – Rokkor 21mm is better
  • Corner – New-MD 20mm is better

(I judge in average over the entire range of diaphragms, from F2.8 to F11)

It seems to me that both lenses are winners. But I realize that fans of Rokkors will find advantages of MCII 21/2.8 and fans of New-MD will find advantages of 20/2.8. To avoid subjectivity I recommend both lenses. Enjoy!
