What We Like
+Exceptional sharpness from f/1.4 throughout the frame with excellent center performance
+Premium all-metal build with weather sealing at a $549 price point—rare feature richness
+Smooth, quiet STM autofocus with eye-AF and subject tracking for video
+Lightweight at 490g, making it highly portable for handheld and gimbal work
+Switchable aperture ring (clicked or stepless), iris lock, and AF/MF switch for professional control
+Beautiful rendering and creamy bokeh with 13-blade diaphragm, especially strong for video
Worth Knowing
−Slower autofocus performance limits fast-paced action or sports photography
−Pronounced vignetting at f/1.4 (improves by f/2.8 but never fully disappears)
−Minimum focus distance of 35cm is longer than many competitors; limited macro capability at 0.14x magnification
−No optical image stabilization; relies on in-body stabilization or tripod support
