Verdict

Sigma proved once more that they are no longer a company providing budget lenses but are playing in the top league indeed.

The Sigma 50mm f/1.4 DG HSM | A (Art series) is very sharp at f/1.4 already, especially in the image center but even the corners are very decent. The quality is excellent across the entire image frame between f/4 and f/8. The lens is also comparatively punchy (high contrast) at large apertures.

Lateral CA are basically absent. Distortion is visible, but limited to the image corners. Unsurprisingly there is some noticeable vignetting at f/1.4, but it's mostly gone by f/2 already.

The quality of the bokeh is excellent as far as out-of-focus highlights are concerned. The general background blur is also smooth, less so the foreground blur. The amount of bokeh fringing is typical for a lens in this class. There's a very slight amount of focus shift when stopping down. However, the focus point mostly stays within the increasing depth-of-field except at really close focus distances.

It's no news anymore that Sigma's Art series lenses are both beautifully crafted as well as tough and it's really a joy to handle this lens. The AF is very fast and near silent.

So, in summary, a "Highly Recommended" lens - and better than all the other 50mm AF lenses that we have tested to date.
