Is the ttartisan af 24mm f 3 8 mini good for landscape?
Yes, it's a sensible pick for landscapes on a full-frame camera. At 24mm it's a bit less wide than the 16-35mm zoom the landscape guide calls the classic choice, but it still takes in big skies and strong foregrounds. The f/3.8 maximum aperture doesn't matter much here, because you'll usually shoot between f/8 and f/11 anyway. At about 57 grams it's easy to carry on long walks, and since landscape work is often done on a tripod, the lack of stabilisation won't bother you much.
On APS-C it frames like 36mm, which is too tight for most landscape scenes, so I'd look for a wider option there. For the full picture of what suits landscape work, see the landscape page.
