Tokina AF 193 19-35 mm f/3.5-4.5
5. Chromatic aberration
For the users of the Tokina 19-35 mm the chromatic aberration shouldn’t be a big problem because at most focal lengths and apertures it keeps the level of 0.08% or lower. It’s worth reminding that the values ranging from 0.04% to 0.08% we consider as low.
To tell you the truth some colour artifacts can be noticed at the ends of contrasting edges but only when we are near maximum relative aperture at 19 mm. The aberration reaches the medium level of over 0.1% there.
Overall, the performance in this category should be assessed very positively, especially as we deal here with a zoom lens which is wide angle even on small APS-C/DX sensors.
