LensRomantic: Minolta MD 28mm 1:2.8 (7 elements in 7 groups)

Comparison of two different copies of Minolta MD 28mm 1:2.8 – 7 elements in 7 groups formula. (New-MD, NMD, MDIII)

‘LensRomantic’ tests description is here. Tests of this type are mostly for collectors or tech-enthusiasts, but for photographers, I recommend going directly to the lens review.

Copy #1 Copy #2
Serial: 8072626 8095781
Optical Condition: Excellent Excellent
Mechanical Condition: Near Mint Near Mint
Cosmetic Condition: Near Mint Near Mint

This comparison is correct only for conditions and equipment used for tests. Test results can 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.

Notes:
  • Sunlight has been slightly changed during the session.

‘What does it mean?’ – my conclusion:

I don’t see any difference which should be mentioned. Both lenses work like twins.

Note: some photographers believed that this lens with the 7×7 formula is one of the best at Minolta on a focal length of 28mm. But tests on the site several times showed that this is not so. Yes, the lens is not bad, but far from the best. Then some readers suggested that the tested copy has issues. Now there is a confidence that everything is OK with copies and with test results too.
