Minolta New MD 28mm F2 lens review.

I was impressed with this lens right after I saw the results of its testing. In fact, in my practice as an amateur photographer, I rarely use such a focal length. But now I even regret it a little, since this lens gives tremendous confidence in the result obtained in the photo.

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 – some expensive modern lenses can provide a little bit more 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. Works fine with auto-focus adapters like Techart-Pro, and still convenient enough if you prefer manual focusing. Aperture F4 can be enough for landscapes (! – unbelievable), and center is fine even wide opened.
