This lens is small, lightweight (250 gr), well built, solid, it is balanced well with my Nikon Df (190gr), which is important for travel; I tried it with a series of photos: if I had to nitpick, I would say that 2.8 there is a slight vignetting and 4 perhaps (and again), but I will use it well mini openings for a maximum depth of field. And I put them on the Auto ISO Df for some dim lights. In this regard, the 24 has a very good dive, so at 4000 ISO, 400% enlarged picture is very beautiful. Anyway, the bottom line is to make beautiful pictures, right? Or at least try ...
