LensWars: Minolta MD 24mm f/2.8 vs. MD VFC 24mm f/2.8

Comparison of lenses Minolta MD 24mm 1:2.8, Minolta MD VFC 24mm 1:2.8.

The VFC lenses aren’t in popular optics list, hope the article will be interesting not only for photographers but for researches too.

Among all lenses Minolta, which have been tested on the site, New-MD 24 / 2.8 has brought more problems. Some time after the test and review, I managed to get another copy of the lens, and it turned out that it was noticeably sharper than the first. According to other materials on the Internet, I’m sure that this sharpness is more suitable for this model, and a new copy – the most correct.
I had to redo all the tests with a 24mm lenses (including zoom lenses) on an infinite distance and this current article is in the list.
On this page you can read the already corrected edition of the article with the most reliable data.

  • Minolta MD 24mm 1:2 – sn. 3115101
  • Minolta MD VFC 24mm 1:2.8 – sn. 8001416

Minolta MD 24 F/2.8 review avatar


Test description: Camera Sony A7II (24mpx, full frame) – fixed on the tripod. Targets (buildings) – fixed by gravity power on the distances in more than 200 meters. All shots were made with apertures from fully opened F2.8 and up to F16. ISO-100. Shutter Speed – depends on light (camera A-mode), WB – same for all shots. SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift affecting. Focus point – center of the picture.

Finally, pictures were converted from ARW-files in Capture One with default settings, cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files.

Field curvature control on Minolta MD VFC 24mm f/2.8 is set in the center position

Note: I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.

My conclusion:

Minolta MD VFC 24mm F2.8 and Minolta MD  24mm F2.8 – work the same at the center  and middle but for corners the non-VFC version shows a much better result – it becomes ready for landscapes on F5.6 or even may be on F4 (!) and totally sharpen at F8, but the VFS can’t approach full sharpness over the frame at a whole diapason from F2.8 to F16. The newer optical design of New-MD 24mm 1:2.8 non-VFC has won.
