Canon RF-S 18-45mm f4.5-6.3 IS STM Lens

Key Features

• Versatile Everyday Zoom Range: Offers a 35mm equivalent focal length range of 29-72mm, gracefully transitioning from wide-angle landscapes and street snapshots to flattering portrait framing.
• Up to 4 Stops of Optical Image Stabilization: Built-in optical IS counteracts camera shake by up to 4 stops, scaling up to 6.5 coordinated stops when mounted on EOS R bodies featuring In-Body Image Stabilization (IBIS).
• Stepping Motor (STM) Technology: Employs a lead screw-type stepping motor that delivers smooth, near-silent, and incredibly precise autofocus tracking, making it exceptionally reliable for cinematic video capture.
• Ultra-Compact Retracting Structure: Utilizes a mechanical locking barrel that retracts down to a mere 44.3mm in length when stowed, fitting comfortably inside small everyday packs or coat pockets.
• Featherweight Form Factor Optimization: Weighing only 130 grams, this lens minimizes physical fatigue during prolonged hand-held shooting sessions or lightweight travel excursions.
• Two PMo Aspherical Elements: Features an optical design consisting of 7 elements in 7 groups, packed with two precision-molded aspherical elements to sharply suppress distortions and chromatic aberrations.
• Super Spectra Coating: Applied to individual glass surfaces to systematically reduce lens flare and ghosting, maintaining rich image contrast and natural color accuracy in bright conditions.
• Dual-Function Control & Focusing Ring: Features a unified, textured physical barrel ring that users can program to manage precise manual focus or dial in exposure adjustments like ISO, exposure compensation, and aperture.
• Rounded 7-Blade Diaphragm: Produces soft, rounded out-of-focus highlights and a pleasing bokeh background to gracefully isolate subjects during close-up framing.
• Impressive Manual Close-Focusing: Achieves a minimum focusing distance of just 15 centimeters with a 0.25x magnification ratio when switched to manual focus at the 18mm end, capturing miniature details cleanly.
