LensWars: Minolta MC I 28mm f/3.5 vs. MC II Rokkor 28mm f/2.5 vs. MC II 28mm f/3.5 vs. MD III 28mm f/3.5

Comparison of lenses Minolta MC I 28mm 1:3.5 vs. MC II Rokkor 28mm 1:2.5 vs. MC II 28mm 1:3.5 and Minolta MD III 28mm 1:3.5.

This is a battle of the not expensive Minolta wide lenses – 28mm focal distance with not too fast apertures is on the scene. Lensqaworks has another one battle dedicated to New-MD lens generation and it seems that this comparison of the MC era can extend an understanding of how this focal distance was covered by Minolta.

Minolta MD III 28mm 1:3.5 is presented here in the role of a link to other comparisons of lenses with 28mm focal distances on the site – this lens took part in many battles, details can be found in the down of the page with the lens-review.

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

(Due to the yellow tint on the glass of MC II 28mm F/2.5, the rating is not reduced)


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 changed during the session

‘What does it mean?’ – my conclusion:

  • Minolta MC 28mm f/3.5 (MC I) vs. Minolta MC 28mm f/2.5 (MC II)

Rokkor MC 28/2.5 has an advantage in the middle and corner positions. Not a lot, but it is the winner of course in this pair. What about the center – at F3.5-4.0 both lenses enough the same.

  • Minolta MC 28mm f/3.5 (MC I) vs. Minolta MC 28mm f/3.5 (MC II)

Both are absolutely the same in the center and middle but in the corner younger Rokkor MC II wins with an easily visible difference.

  • Minolta MC 28mm f/2.5 (MC II) vs. Minolta MC 28mm f/3.5 (MC II)

Here is the win-win case – both are the same in the center, the faster Minolta MC 28mm f/2.5 wins in the middle but loose in the center.

  • Minolta MC 28mm f/2.5 (MC II) vs. Minolta MD 28mm f/3.5 (MD III)

Both are the same in the center and corners but younger New-MD wins in the middle too.

The final chart:

  • Minolta MC Rokkor SG 28mm f/3.5 (MC I) – is not the winner but still very usable lens
  • Minolta MC Rokkor SG 28mm f/3.5 (MC II) – “half-winner”, the best for closed apertures
  • Minolta MC Rokkor SI 28mm f/2.5 (MC II) – “half-winner”, the best for opened apertures
  • Minolta New-MD 28mm f/3.5 (MD III) – is from much younger generation and I prefer to remove it from the chart with lenses from 60′ due to fair-play principles.
