Sony 20mm F
And when you issue that these scores are recorded with all in-digicam aberration correction disabled, these results are even more spectacular. Lateral chromatic aberration is so negligible that there’s hardly any color fringing, even at in direction of the intense corners of the body. Longitudinal chromatic aberration or ‘bokeh fringing’ is similarly minimal, with negligible fringes around edges of objects that lie in front of or behind the purpose of focus – once more, even when shooting extensive open at f/1.eight. Even more exceptional for such a compact ultra wide-angle lens, there’s extremely little distortion. Vignetting can be noticeable at the widest aperture, but automatic in-digital camera correction is out there.
