What We Like
+Smallest and lightest F2.8 ultra-wide zoom for APS-C cameras at 260g and 62mm length
+Fast constant F2.8 aperture delivers superior low-light performance compared to Canon's variable F4.5-6.3 lens
+Excellent optical performance with minimal distortion, low chromatic aberration, and well-suppressed flare
+Fast, silent, and accurate autofocus with minimal focus breathing ideal for video work
+Ultra-compact and portable design with push-on petal lens hood for travel and gimbal mounting
+Close minimum focusing distance (11.6cm at 10mm) enables 1:4 macro magnification for unique compositions
Worth Knowing
−No optical image stabilization (unlike Canon's RF-S 10-18mm F4.5-6.3), requiring camera IBIS or higher ISO in low light
−Higher price point at $659 versus Canon's $329 alternative, though justified by faster aperture
−Limited weather sealing compared to Art or Sports lines—gasket at mount only, not full lens body sealing
−Soft edges and corners at wide apertures (F2.8), particularly noticeable at 10mm focal length
