Another Minolta New MD 35mm F1.8 lens review

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.

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.

Geometric distortion:

(frame scaled 1200×800)


Coma aberrations:

(100% crops – 300×200)


Chromatic aberrations:

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 35mm 1:1.8F (Minolta MD III 35mm F/1.8):

Photographers are divided into two groups – someone prefers 50mm as the main lens, someone likes 35mm (someone are fans of 28mm, but this group is smaller). So, if photographer prefer 35mm – then this lens is the best choice. It has enough sharpness for landscapes (started from F4 I think) and gives thin DOF for portraits – I mean that this lens is enough ideal to be universal. With this lens I rarely think about the aperture – because lens is good starting from 1.8. As previous lens it works fine with auto-focus adapters like Techart-Pro, and still convenient enough if you prefer manual focusing. This lens is my third number in bag if I’m going to make a portraits.
