What We Like
+Fast constant f/2.8 aperture throughout the zoom range for low-light performance
+Compact and lightweight design (320g) that's easy to carry and use with gimbals
+Excellent optical performance with minimal distortion and low light fall-off
+Quick, silent autofocus motor with reliable focus in video and photo modes
+Very affordable pricing compared to competing ultra-wide-angle zooms
+Weather sealing for durability in challenging outdoor conditions
Worth Knowing
−Peak sharpness at 11mm; slightly less impressive performance at 18mm without stopping down to f/5.6
−Limited zoom range (7mm) compared to some competitors like the Tamron 11-20mm
−Lens extends physically as focal length decreases, which may be a concern for gimbal users
−Plastic construction feels less premium than some higher-priced alternatives, though build quality is solid
