turns out, the concrete wall just had the "proper" structure to bring out a downside of the 85/1.8 S. Yesterday evening I took both lenses on different cameras and shot some situations with various combinations of distance between camera, main-subject and background. I only can tell which lens in the comparison is the Nikkor and which the Sigma by looking at the EXIF.
Due to tiny focus-differences (also caused by different mode of manual focusing . the Sigma reacts direct, the Nikkor slightly laggish) I would not be confidently sayingg one is clearly better than the other. Contrast appears to be slightly better on the Nikkor - but that might come from various recipes of Capture One, handling camera and lens profile.
Still, there are otehr differences. Weight and size are the obvious ones. The laggish reaction to manual focus and the lack of a distance scale are less obvious, but in some situations relevant. Like observing the focus ring if it is stacking or not. If it goes beyond ∞ 8and produces useless files) or not and if so, after how many shots.
I do use focus stacking a bit more, but there are some quirks about which I often think, it would have been nearly the same costs to implement the function properly and useful.
The last bit what I want to check is CA (with and without correction), but I need sunshine to do this.
