What We Like
+Near-zero distortion for straight lines in architecture and landscape work
+Compact metal construction at only 504g makes it highly portable
+Rare 77mm filter compatibility for an ultra-wide prime via included adapter
+Fast f/2.8 aperture excellent for astrophotography and low-light shooting
+De-clickable aperture ring ideal for both stills and video work
+Sharp edge-to-edge performance at wide aperture with excellent color reproduction
Worth Knowing
−Manual focus only with no autofocus support for any mount
−Significant flare issues when bright light sources are in frame, especially at f/2.8
−No image stabilization; requires in-body IS or tripod for slower shutter speeds
−No weather sealing or environmental protection
