LensWars: Minolta MC Rokkor PF 100mm f/2.5 vs. MC Rokkor QE 100mm f/3.5 vs MD 100mm f/2.5

Comparison of lenses Minolta MC Rokkor PF 100mm 1:2.5 vs Minolta MC Rokkor QE 100mm 1:3.5 vs Minolta MD 100mm 1:2.5

100mm is very popular portraiture focal distance for today, demanded by photographers. Instead of 135mm the number of available 100mm lenses are times less, and prices can’t be called as small. Each of these three tested lenses has a different feature that makes every lens strong. Therefore, the final choice is likely to be based not on the sharpness but on personal preferably of photographer. Anyway, let’s select a champion in resolution.

This comparison is correct only for conditions and equipment used for tests. Test results can be differ if any element is changed.

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.

Note:
  • I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.

  • Middle: MD 100/2.5 has a micro-nano-pico advantage
  • Corner: win-win. Or even a little-nano advantage of MC 100/3.5 if to take a look with a microscope. Sounds impossible, but it’s true

Results:

  • 1st place: Minolta MD 100mm 1:2.5 of course. It’s for ages younger than Rokkor 100/2.5 and one stop faster than Rokkor 100/3.5
