Digital Camera World Verdict

Portraiture and still life can be a struggle with a crop-sensor camera, especially if you want nice creamy bokeh, giving a sumptuous smoothness to defocused areas. With an ‘effective’ focal length of 85mm, 90mm and 112mm on Sony E, Canon M and Micro Four Thirds bodies respectively, the f/1.4 aperture rating of this Sigma 56mm f/1.4 DC DN | C lens gives you full control over depth of field, at a very competitive price.

Think ‘portrait lens’ and you might be thinking of a brooding hulk like Sigma’s 85mm f/1.4 Art optic for full-frame SLRs. That lens weighs in at over a kilogram and has a similarly hefty price tag. By contrast, the Sigma 56mm f/1.4 DC DN | C lens is less than half the physical length, a quarter of the weight and about a third of the price. Nevertheless it has exactly the same aperture rating and gives a similar effective focal length.
