What We Like
+Exceptionally compact and lightweight design at only 220g, the lightest in Sigma's F1.4 DC series
+Fast F1.4 aperture enables low-light performance and shallow depth-of-field creative control
+Excellent edge-to-edge sharpness across entire frame, even wide-open, with minimal sagittal coma flare
+Competitive pricing at $579 USD versus Sony's 15mm F1.4 G at nearly $950
+Dust and splash-resistant construction with improved weather sealing over predecessor
+Smooth, responsive stepping motor autofocus with well-controlled focus breathing ideal for video
Worth Knowing
−Polycarbonate construction offers less weather protection than higher-end Art series lenses
−Corner sharpness is noticeably softer at maximum aperture, requires stopping down to F5.6+ for optimal corner performance
−Shows some vignetting and distortion at wider apertures that diminishes when stopped down
−No built-in image stabilization (relies on camera body IBIS)
