What We Like
+Exceptional value at $199 USD - smallest, lightest, cheapest 14mm AF prime for full-frame
+Outstanding sharpness at f/4 across entire frame with minimal vignetting correction needed
+Compact (65mm diameter, 56.4mm length) and ultralight (170g) design ideal for travel
+Fast, silent, and accurate autofocus with eye/face detection and minimal focus breathing
+Excellent optical control of distortion (2.07% barrel), chromatic aberration, and field curvature
Worth Knowing
F4.0 aperture limits low-light performance and shallow depth of field compared to faster alternatives
No full weather sealing - only sealed body with water-resistant front element coating
Moderate to heavy vignetting at f/4 (approximately 3 EV) requires software correction
Field curvature at close focus distances requires focus stacking for perfectly flat subjects
