Canon RF 24mm F/1.8 Macro IS STM Lens

The Canon RF 24mm f/1.8 Macro IS STM Lens is a versatile wide‑angle prime lens designed for Canon’s full‑frame EOS R‑series mirrorless cameras. With a fixed focal length of 24 mm and a bright f/1.8 maximum aperture, this lens combines wide‑angle perspective with strong low‑light performance and creative depth‑of‑field control. It also includes macro capabilities, giving photographers the flexibility to shoot both expansive scenes and close‑up subject detail without changing lenses.

Optically, the lens features an 11‑element, 9‑group construction that incorporates one Ultra‑Low Dispersion (UD) element and one aspherical element to help control chromatic and spherical aberrations, resulting in clearer imagery with better contrast and reduced distortion. Canon’s Super Spectra Coating further minimizes flare and ghosting when shooting in bright or backlit conditions, contributing to accurate color reproduction and clean highlights.

One of the standout characteristics of this lens is its fast maximum aperture of f/1.8, which allows for excellent performance in low‑light situations, faster shutter speeds, and smooth background blur (bokeh) for subject isolation even at a wide focal length. The lens uses a 9‑blade rounded diaphragm, enhancing the quality of out‑of‑focus areas for pleasing aesthetic effects in portraits, environmental shots, and creative compositions.

The RF 24mm f/1.8 Macro IS STM also delivers useful macro capabilities with a 0.5× maximum magnification ratio (1:2 reproduction) and a minimum focusing distance of approximately 0.14 m (14 cm). This lets photographers get close to their subjects — such as flowers, food, props, or details in scenes — while still capturing a large portion of the background, thanks to the wide‑angle view. This combination creates a unique wide‑angle macro look that blends environment and detail in a way that standard macro lenses do not.

Autofocus performance is driven by Canon’s Stepping Motor (STM) system, which provides smooth, quiet, and accurate focusing — particularly beneficial when shooting video or during silent stills sessions. The lens also includes Optical Image Stabilization (IS) that delivers up to 5 stops of shake correction on its own, and up to 6.5 stops of coordinated stabilization when paired with a camera body that has In‑Body Image Stabilization (IBIS). This makes handheld shooting easier, especially in low‑light conditions or at slower shutter speeds.

In terms of handling, the RF 24mm f/1.8 Macro IS STM is compact and lightweight, weighing only about 270 g and measuring approximately 74.4 × 63.1 mm, making it highly portable for travel, street, and everyday photography. A customizable Control Ring lets users adjust key exposure settings (like aperture, ISO, or shutter speed) directly on the lens, while the STM’s whisper‑quiet focus makes it ideal for hybrid shooters who frequently switch between stills and video.

The wide 24 mm focal length provides a natural perspective that is well‑suited to landscapes, architecture, environmental portraits, street scenes, and vlog‑style video, while the macro capability and bright aperture add creative flexibility for detailed close‑ups and artistic visuals. On APS‑C sensor bodies, the lens produces an effective focal length of approximately 38 mm — a familiar and versatile perspective for everyday shooting.

Overall, the Canon RF 24mm f/1.8 Macro IS STM Lens is a multi‑talented wide‑angle prime that delivers a blend of wide coverage, macro capability, low‑light performance, effective stabilization, and smooth autofocus — all in a compact and user‑friendly package. It’s a solid choice for photographers and videographers looking to expand their creative options without sacrificing portability or image quality.
