Comparison of two different copies of Minolta MD 28mm 1:2.0. (New-MD, NMD, MDIII)
‘LensRomantic’ tests description is here. Tests of this type are mostly for collectors or tech-enthusiasts, for photographers I recommend to go directly to the lens review.
Minolta New-MD 28mm F2.0 is the best in 28mm manual lenses line. I have a dream to compare it with modern lenses by Leica or Sony or something like that but for today can offer a just one another LensRomantic photo session.
|Copy #1||Copy #2|
|Optical Condition:||Near Mint||Excellent|
|Mechanical Condition:||Very Good||Near Mint|
|Cosmetic Condition:||Very Good||Near Mint|
This comparison is correct only for conditions and equipment used for tests. Test results can 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.
- Sunlight has been changed during the session.
‘What does it mean?’ – my conclusion:
Copy #1 increases the sharpness in the corner faster than the number two. It can be seen easily around F4.0. To avoid doubts about the uneven deviation of the optical axis of the lens, I made an additional diagram with samples taken in the opposite corner.
The result remains the same, copy #1 has a little better resolution on F4.
