Comparison of lenses Chiyoko Super Rokkor 8.5cm 1:2.8 LTM (LSM), Minolta MD 85mm 1:2.0
The one of the first versus one of the best. Not a battle actually, better to call it friendly match.
This comparison is correct only for conditions and equipment used for tests. Test results can be differ if any element is changed.
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.
- I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.
‘What does it mean?’ – my conclusion:
This comparison is only for demonstration of Chiyoko performance near the well known Minolta MD 85/2. The idea isn’t to say that Super Rokkor is bad – of course MD has won in all aspects, the idea is to show for what photographer should be ready if going to make a few masterpieces with old style lens.
