Another Minolta New MD (MD III) 200mm F4 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.

Lens code name – Assam アッサム

Assam – is a student from St. Gloriana Girls High School. She serves as the gunner of the Churchill tank, and also as an analyst, able to identify the weak-points of tanks with ease, as well as calculating a battle’s odds of success or failure.

Assam also conducts intelligence operations, infiltrating and eavesdropping on other school’s plans. She constitutes the entirety of St. Gloriana Sensha-Dō Team’s Data Processing Department, Section 6.


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:

This lens doesn’t have a visible geometric distortion. No tests needed.

 


Coma aberrations:

(100% crops – 300×200)


Chromatic aberrations:

(100% crops – 300×200)


Close distance bokeh:

Test conditions: lens was focused on to minimal distance (2.5m), plants were fixed in 5m 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 (4.5m), 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 3m), diodes were  fixed in 5m distance at the dark background.

(frame scaled 1200×800)


My overall conclusion about the Minolta N-MD 200mm 1:4.0F (Minolta MD III 200mm F/4):

To my regret, I have never use it in real photo-sessions, so my conclusion is based on tests results: lens is really sharp and gives smooth ‘creme’ bokeh, it means that it very universal. Combination of wide opened F4 with this so long 200mm focal distance is enough for any tasks which I can imagine – portraits, landscapes, animals/birds in parks, etc. Actually, it can be preferable instead of faster MD 200mm F2.8 because gives an another level of convenience in walks.  Lightweight is important advantage of it, and one more plus – build-in lens-hood, another plus – it has absolutely low price, just about a few bucks. Really, it’s abnormal – for today it’s one of the cheapest lens in Minolta MD line. Lens can be operated with auto-focus adapters like Techart-Pro, but be careful (!) – it gives too long ‘lever’ for mount fix. Of course it has an aberrations, but anyway – it ready to work even if wide opened. Powerful, long-focused and convenient lens.
