5. Chromatic and spherical aberration

Chromatic aberration

The tested lens doesn't have any problems with longitudinal chromatic aberration – its influence on image quality remains slight and if you spot any colouring in blurry areas positioned further in the frame, its level is not especially bothersome.

In the case of the lateral chromatic aberration the lens can be assessed equally well – a graph below presents its performance depending on the aperture value.

The results are more or less the same and they oscillate near 0.03%. Such a value can be described as very low so there's no danger you can notice chromatic aberration in typical photos taken with this lens.

Spherical aberration

When it comes to the level of spherical aberration it can be described as low. If you take a closer look at first photos from this chapter you can notice a very slight focus shift toward greater distances on stopping down the aperture from f/1.8 to f/2.8. A similar situation can be observed while comparing defocused circles of light – the rim from the circle before the focus is slightly more accented. Apart from that, you can't see anything alarming.
