5. Chromatic and spherical aberration

Chromatic aberration

When it comes to longitudinal chromatic aberration, the tested lens doesn't experience any problems. Of course with such an angle of view and aperture fastness you wouldn't expect any serious problems; it's interesting, though, that two direct Sony rivals, the Samyang 2.8/24 and the Tamron 2.8/24, performed weaker in this category.

In the previous chapter we mentioned problems connected to lateral chromatic aberration – now you can see them in more detail, presented as an appropriate graph and in photos of our testing chart.

As at the maximum relative aperture you can talk about a medium level, on stopping down the aperture this aberration rises quite fast to values we consider to be high. In this category all savings on the number of elements, and special glass elements make themselves felt. The result is such that the significantly more expensive Sony 2.8/24G corrects lateral chromatic aberration noticeably weaker than the Tamron and a tad weaker than the Samyang.

Spherical aberration

First photos of this chapter don't show any noticeable 'focus shift' effect but it's a bit difficult to observe anything - a quite significant depth of field, stemming from the parameters of the lens, doesn't make the observations easy. When it comes to cricles of light, generated before and behind the focal point, spherical aberration is a bit bothersome with its classic symptom – a light rim of the circle on one side of the focus and lack of it on the other side. Also in this category the lens doesn't perform according to our expectations but we admit that such problems aren't especially serious.
