Canon's versatile RF wide-angle prime with IS, macro capability, and fast f/1.8 aperture.
The Canon RF 24mm f/1.8 Macro IS STM was released in 2021 as part of Canon's compact RF prime lineup, sharing the same concept as the RF 35mm f/1.8 IS STM Macro — wide perspective, built-in IS, 0.5x macro capability, and STM motor — at the wider 24mm full-frame focal length. At 0.14m the minimum focus distance is closer than the RF 35mm's 0.17m, and the wider angle of view provides more foreground-to-background environmental context at close focus distances. The 52mm filter thread is shared with the RF 35mm f/1.8 IS STM Macro.
The optical design uses 11 elements in 9 groups. Nine aperture blades produce smooth out-of-focus rendering. The 52mm filter thread is shared with the RF 35mm f/1.8 IS STM Macro — a single filter set covers both compact RF primes. At 270g the lens matches the RF 35mm in weight. Minimum focus distance of 0.14m achieves 0.5x (1:2) reproduction — half life-size on the sensor. IS is built in, providing stability at both normal shooting distances and close-focus macro magnifications. STM motor enables near-silent continuous AF for video use. There is no weather sealing.
The 24mm full-frame perspective is a moderately wide field of view — wider than the 35mm's standard-wide angle but not ultra-wide. For environmental portraiture, documentary, travel, and interior photography where slightly wider context is needed, 24mm provides a practical working perspective. The 0.14m MFD enables close foreground subjects with full wide-angle background context in a single frame — a compositional approach common in landscape foreground detail and product photography. IS is practically useful at macro distances where camera vibration at higher magnification amplifies shake.
On the used market the RF 24mm f/1.8 Macro IS STM is widely available at accessible prices. Condition checks: IS engagement, STM AF motor response, and front element for any marks. The lens has no weather sealing. The 52mm filter thread is shared with the RF 35mm f/1.8 IS STM Macro — filter carry-over is practical when both are in the same kit. The Canon RF 24mm f/1.4L VCM provides L-series weather sealing and a wider maximum aperture at substantially higher cost. Compatible with all Canon RF-mount bodies.
