In general, if you need a good portrait lens, I will attach a few photos taken on the nikon D800 The first one was shot with 2 different lenses, against the background of blinds specially in the same conditions, nikor on the left, sigma art on the right) Nikor' notice the complete lack of detail on the white curtain and the awful chromaticity that makes the model's hair look purple! The third is an example of "volumetric and artistic" bokeh :)
