In general, only positive impressions. If you haven’t shot with fixed lenses yet, be sure to try it, the sensations are completely different. Some pros: My first prime lens. Before that, there was a zoom of 18-140. I hesitated for a long time before buying, but the desire to try something new outweighed. And I never regretted it. I installed it and since then I have been shooting only on it (even landscapes, although I originally planned to use it exclusively for subject photography). Photos are sharper, the blur is noticeably stronger than on a zoom lens. In general, they look more artistic and pleasant. Some cons: Autofocus is not always accurate. But I was ready for this - this was written in many reviews that I read before buying. I almost never shoot moving objects, so for me this drawback is not critical - in extreme cases, it is possible to manually refocus.
