- Wide open, the lens is impressively sharp across the frame and over the zoom range on its native platform (full frame), although there’s an unavoidable drop-off near the corners.
- Minor amounts of CA were noticed.
- Vignetting is moderate wide open, at all focal lengths.
- Distortion goes from slight barrel (-0.8%) at 24mm to minor pincushion (+0.4%) at 35mm.
- AF is very quick.
What stands out from this review is the consistent behavior of the Sigma 24-35mm f/2 Art. The lens showed an even and high-grade performance throughout its range.
As a complement, check out Sigma’s own sample photos — lots of close-ups, so you can see if the bokeh is to your liking.
