Tested lenses reviews:
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, then cut into 300×200 px elements (100% crops), combined into diagrams and exported into JPEG-files.
- Sunlight has been changed during the session.
- I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.
- Both are great even if wide opened. Even from the modern point of view.
- Super Rokkor 50mm F2.0 becomes acceptable at F4 and totally sharp at F8
- Super Rokkor 50mm F2.8 is acceptable from F5.6, and only at F11 it can provide maximum resolution. Unfortunately, this maximum level is a little bit less than what was shown by Super Rokkor 50mm F2.0 and never will be equal, even at F16.
- Super Rokkor 50mm F2.0 becomes acceptable from F2.8, it’s not a mistake, all tests demonstrate better resolution in corners than in middle on infinity. Very good sharpness is on F5.6, and F8 is ideal for landscapes.
- Super Rokkor 50mm F2.8 becomes acceptable at F11, and never becomes totally sharp.
That’s not a surprise that Super Rokkor 50mm F2.0 is a winner in terms of sharpness, so it’s better for landscapes, but it’s impossible to say what lens is better for other photo-styles, because bigger aberrations can provide more artistic possibilities,.. or can’t – depends on taste of photographer.
