The quality is also maintained very well when stopping down.

That’s not really an issue with this lens, which delivers super-smooth, high-quality bokeh. We’ve seen a slight onion ring effect in the bokeh of some Sigma lenses, appearing as concentric circles with feint lines within bokeh discs of defocused lights and bright spots.

Autofocus is courtesy of a conventional ring-type ultrasonic system with the usual full-time manual override. The up-market build includes an aspherical element and two SLD (Special Low Dispersion) elements, in an optical path that comprises 14 elements in total. Ideal for a wide-range of cameras, this full-frame compatible lens is available in Canon EF, Nikon F, Sony E and Leica L mount options, the last of these making it eminently suitable for Panasonic’s new S-series bodies.

Even so, despite having a less outsized aperture rating, the Sigma is still physically slightly longer than the Canon and nearly as heavy, weighing in at 1,130g. We’ve always considered this Sigma to be abnormally large and weighty for an 85mm f/1.4 lens, but that was before the Canon RF 85mm f/1.2 burst onto the scene.
