What We Like
+Exceptional optical sharpness even at f/1.4 aperture across most of the frame
+Remarkably compact and lightweight for an ultra-wide f/1.4 prime
+Silent and fast VCM autofocus ideal for both stills and video
+Premium build quality with weather sealing and L-series durability
+Advanced optics with fluorite glass elements for superior astrophotography performance
+Excellent focus breathing control for professional video work
Worth Knowing
−Premium price ($2,599) makes it substantially more expensive than competing VCM lenses
−Automatic in-camera distortion correction cannot be disabled
−Limited close-focusing capability (0.24m) with only 0.11x magnification
−Corner softness at extreme edges reported in some tests, particularly for astrophotography
