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 cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files

Notes:
  • Sunlight has been changed during the session.
  • I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.

My conclusion:

No doubts that 4x long zoom isn’t so good as prime lenses on any focal distances, in corners at least, but question was – for how much? Every photographer has own ideas about size of reasonable decreasing of sharpness as payment for convenience, so better not to read  personal opinions but research the diagrams. Anyway, my conclusion about this lens in main review hadn’t changed after I got results of comparisons.
