Review: Minolta MD 24mm 1:2.8

Another Minolta New MD 24mm F2.8 lens review.

Very popular lens, it stays on position close to legendary status. Has a great IQ and can give for owner everything which can be expected from 24mm fast prime. If you are not sure that you need it then look over tests.

After getting a new lens, I always take a few technical shots to understand its strengths and weaknesses – usually, it helps me a lot to start using an unknown lens with much less of doubt. One day I decided that my data might be interesting for someone else and this site has been made.

Lens code name – Maho Nishizumi 西住 まほ

Maho Nishizumi – is a third year student at Kuromorimine Girls High School. She’s the overall commander of her school’s Sensha-dō team. Maho is also the heiress to the Nishizumi Family. She is the commander of a German Tiger I. She is the older sister of Miho Nishizumi (N-MD 50mm F1.2). Maho comes from Kumamoto City, Kumamoto.


Resolution – close distance:

Test description: target is a 10×15 cm picture (printed, glossy photo paper), fixed on the wall by scotch. Distance – about 10% longer than minimal focus distance marked on the lens. Camera Sony A7II (24mpx, full frame) was fixed on the tripod and managed remotely with computer display as a viewfinder. All groups of shots were repeated 9 times for every target position on all apertures from fully opened up to F16, ISO-100, WB – same for all shots. SteadyShot – OFF. Focus was manually corrected for each shot. After all needed shots have been taken for one target position – I moved  the target to the next place.

Main idea – to exclude the field curvature affect on so close distance.

Of course, I can’t be absolutely accurate, but so many repeats of shots – 4 for corners, 2 for long side, 2 for short side are giving me insurance that test results are correct.

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 cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files.

Resolution – long distance:

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 have been taken with apertures from fully opened up to F16. ISO-100. Shutter Speed – depends on light (camera A-mode), WB – fixed and the same for all shots. SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift affect.

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 were cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files.

Vignetting:

(frames scaled – 300×200)


Geometric distortion:

(frame scaled 1200×800)


Coma aberrations:

(100% crops – 300×200)


Chromatic aberrations:

(100% crops – 300×200)


Close distance bokeh:

Test conditions: the lens is focused on minimal distance (0.25m), plants are fixed in the 2m distance on the window, so the scene has a bright back-light.

(frame scaled 1200×800, bokeh is presented on some part of the frame)


Long distance bokeh:

Test conditions: lens was focused on half distance on the scale (0.5m), houses were fixed in infinity distance on the ground.

(frame scaled 1200×800)


Light dots bokeh:

Test conditions: lens is focused on to minimal distance + 10% of scale (about 0.25m), diodes are fixed in 2m distance at the dark background.

(frame scaled 1200×800)

My overall conclusion about the Minolta N-MD 24mm 1:2.8F (Minolta MD III 24mm F/2.8):

It has quite nice geometry and sharpness for 24mm – one of best wide lenses independently of the manufacturer. If 24mm is your focal distance – you need to get this lens. Additionally, it’s really small and lightweight. Manual focusing is very simple. One more advantage – Minolta made enough amount of this lens, so prices are absolutely reasonable. Center and middle are very good even fully opened, F5.6 is ready for landscapes.
