Another Minolta New MD (MD III) 135mm F3.5 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.

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 (1.5m), 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 (2.5m), 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 1.7m), diodes were  fixed in 5m distance at the dark background.

(frame scaled 1200×800)


My overall conclusion about the Minolta N-MD 135mm 1:3.5F (Minolta MD III 135mm F/3.5):

Lightweight and small-sized – this are main idea to use this lens. Not so fast 135mm as previous MD 135mmF2.0 or MD 135mmF2.8 it works fine from F5.6 for most of tasks, and can be used wide opened for portraits. In addition, the lens has a nice bokeh. Works good with auto-focus adapters like Techart-Pro. Build-in lens-hood is presented. Actually, this lens is very close to MD 135mmF2.8 but one stop has been lose and performance what you get with faster lens for example – on F5.6, you can get with this lens just on F8. On the other hand it’s really cheap and can always be with you. So, I don’t see a big performance advantages of this lens, but if you are going to long walk – grab it. Also it can be a good choice if you use 135mm focal distances just occasionally.
