Canon RF-S 10-18mm F4.5-6.3 IS STM Lens

• Ultra-wide-angle zoom lens designed for APS-C (crop-sensor) Canon R-series mirrorless cameras (RF/RF-S mount).

• Focal length range: 10–18 mm, equivalent to 16–29 mm in 35 mm full-frame terms.

• Maximum aperture: f/4.5 at 10 mm, narrowing to f/6.3 at 18 mm; minimum aperture: up to f/32.

• Compact, lightweight design — measures approx. 69 mm (diameter) × 44.9 mm (length, retracted) and weighs approx. 150 g.

• Built-in optical Image Stabilization (IS) offering up to 4 stops of shake correction, and up to 6 stops with Coordinated IS when used with a compatible IBIS-equipped body.

• Autofocus driven by a lead-screw type STM (Stepping Motor) — delivers smooth, quiet, and accurate autofocus performance, ideal for video.

• Optical construction: 12 elements in 10 groups, including 2 UD (Ultra-Low Dispersion) elements and 1 aspherical element to reduce chromatic aberrations and distortion.

• Super Spectra Coating minimizes lens flare and ghosting for enhanced contrast and color accuracy.

• 7-blade circular diaphragm helps create pleasing background blur (bokeh), even for a wide-angle lens.

• Minimum focusing distance:

  • 0.14 m (14 cm) in autofocus mode

  • As close as 0.086 m (8.6 cm) in manual focus mode for extreme close-ups with ultra-wide perspective

• Maximum magnification:

  • Up to 0.23x in AF mode (at 18 mm)

  • Up to 0.50x in MF mode (at 10 mm)

• Angle of view (diagonal): approx. 107.5° at 10 mm to 74.3° at 18 mm

• Filter size: 49 mm front thread — allows use of ND, polarizer, and other creative filters

• Lens hood not included — optional EW-53B hood sold separately

• No weather sealing — best used in fair weather or with protective gear

Key Benefits & Use-Cases
