Tested lenses reviews:
Long distance – sharpness:
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 were made with apertures from fully opened and up to F16. ISO-100. Shutter Speed – depends on light (camera A-mode). SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift.
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 cut into 300×200 px elements (100% crops), combined into diagrams and exported into JPEG-files.
- I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.
‘What does it mean?’ – my conclusion:
Well known and very popular Minolta MD 135mm 1:3.5 has a good reputation, but despite this, it still loses to a faster MD 135mm 1:2.8 – on any of positions, but I want to specially notice that in the middle and corner – the difference can be seen up to F8. Does it mean that MD 135mm F3.5 is a bad lens? No of course. Sharpness of this lens is enough for a lot of photographer tasks, and with combination of light weight it can be very useful. What about MD 135mm 1:2.8 – for today this lens so unexpectedly cheap, that it have to be bought even if not needed right at the moment.
