Another Minolta New MD 50mm F1.4 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.

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


Lens code name – Pepperoni ペパロニ

Pepperoni – is a student from Anzio Girls High School, and, together with Carpaccio, she serves as the Sensha-dō team’s vice-commander. She operates a Carro Veloce CV.33.


Sharpness – portrait distance:

Test description: target is a 10×15 cm picture (printed, glossy photo paper), fixed on the wall by scotch. Distance – 1.7m. 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 3 times for every target position on all apertures from fully opened up to F16, ISO-200, 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 test results looks 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 – close distance:

Test description: target is a 10×15 cm picture (printed, glossy photo paper), fixed on the wall by scotch. Distance – about 0.5m – very close to the 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 (0.45m), 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 (1m), 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 0.5 m), diodes were  fixed in 2m distance at the dark background.

(frame scaled 1200×800)


Light dots long distance bokeh:

Test conditions: lens was focused on to minimal distance, lights were fixed in more than 200m.

Such scenes can’t be meet often, so this is demonstration of extreme conditions. In most cases of real life photography the blur level will be less.

My overall conclusion about the Minolta N-MD 50mm 1:1.4F (Minolta MD III 50mm F/1.4):

I agree with people who think that this lens is the best 50mm lens in the world ever. It can be really true – the sharpest among other MD 50mm lenses, it has a quite low aberrations and beautiful bokeh with perfect and interesting character of smoothing. It’s very fast with F1.4 and provides thin DOF. The combination of characteristics makes this lens in my eyes the best around 50mm – it can be used in any style of photos on any aperture with no doubts. One more thing – this lens is better than previous MD 50mm F 1.2 in all aspects, except presented F1.2 of course. And it works great even wide opened. I recommend auto-focus adapters like Techart-Pro especially if you like wide opened apertures, on modern mirrorless cameras the support for manual focusing with thin DOF still isn’t enough. If you are choosing your first Minolta lens – buy this 50/1.4 and you will be inspired into MD lenses at all.

    1. Still didn’t compare but review of Minolta MC Rokkor PG 50mm 1.4 is planned. I hope to get one good copy soon and finish tests before the end of this season

      1. Cool, yes, I’m extremely happy with the Pg, I like it even more than the zeiss 55 (wich I sold), I will play around with both, read your analisis when ready and keep the “best” of them. Regards!
