Welke van de full res voorbeelden is dan scherp?
Hele vreemde resultaten, want afstoppen op 16mm geeft meer onscherpte.
Ze zeggen het zelf trouwens ook:
At 16mm and f/3.5, the Sony E 16-50mm f/3.5-5.6 PZ OSS is fairly soft in the corners and across much of the frame, but the very center of the frame remains fairly sharp. As you stop down, f/5.6 and f/8 appear to be the sweet spot with the largest center area of sharpness; however, the far corners still remain relatively soft. Zoomed in to 35mm, overall sharpness improves, and at f/8, the corners start to look pretty good, although still not tack sharp. At 50mm, you'll see the best results at f/8. Based on the numbers, the best results overall are at 35mm at f/8.
Strangely, at 16mm at f/8, we saw the largest difference between sharpness at the center vs. the corners. The center of the frame was quite sharp, but the corners, conversely, were very soft. This is unusual in our experience; normally sharpness becomes more uniform across the frame as you stop down.
In hun eigen sample kun je ook goed zelf de onscherpte zien en ook de CA die ze dan zelf niet "meten".
En omdat het verschil dus echt zo groot is tussen de reviews moet het bijna wel een QC dingetje zijn en er grote verschillen tussen de individuele lenzen zitten.
De lens is gewoon slecht tot het tegendeel bewezen is.
