Review: Minolta MD 28mm 1:2.0

Minolta New MD 28mm F2 lens review.

I was impressed with this lens right after I saw the first results of testing – this lens gives tremendous confidence in the result.

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 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.

(Please, forgive me the dust on the lens, I never have the patience to clean objects for close-up photo sessions)

Mounted on Minolta X-700:

Lens code name – Hana Isuzu 五十鈴 華

Hana Isuzu – second year student from Ooarai Girls High School, and she is the gunner of Anglerfish Team. Her height is 163cm and her blood type is type B.


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: lens was focused on to minimal distance (0.25m), plants were fixed in 2m distance from camera in front of the window with bright light from outside.

(frame scaled 1200×800, bokeh covers the frame partially)


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 was focused on to minimal distance + 10% of scale (about 0.27m), diodes were  fixed in 2m distance at the dark background.

(frame scaled 1200×800)


My overall conclusion about the Minolta N-MD 28mm 1:2.0F (Minolta MD III 28mm F/2):

This lens is ready to be the only one lens in your bag, if you prefer wide angle instead of normal distances. I can’t say that it has the best sharpness in the world – a few of expensive modern lenses can provide a same level of details, but I have been impressed by results of resolution tests: it was ‘wow!’, especially in the corners. This is a really gem on 28mm, and if it yours distance – take it immediately. Very convenient in manual focusing. Aperture F4 can be enough for landscapes (F4.0 on wide angle! – unbelievable), and center is fine even fully opened aperture.


This lens took part in the battle:

  1. Hey, I was thinking about find some 35mm to my minolta, but now I am quiet excited about something even wider, like 28mm and how it is going to work in fashion/portrait. So, I also consider some m42 lenses. Do you have any knowledge about some good 28, 29 or 30mm for m42? Maybe there are some really affortable ones and give you nice results?
    And another question, is Minolta MC W Rokkor 28/2.0 is as good as the one you’ve tested? 😦

    1. Hi, sorry, I can’t imagine your style of photography and at the same time, there are too many options with m42 mount available. Minolta MC W Rokkor 28/2.0 still has not been tested on the site, so, all that I can say – MC-X and MDIII lenses in most cases /but not always/ show different test results. If you can’t find head-to-head comparison, then I recommend getting an MDIII to avoid risks
