The Canon RF 24mm f/1.8 Macro IS STM is a unique combination of an ultra-wide focal length and a macro lens. Pairing these two attributes, this lens enables shooting at close range while maintaining a broad sense of space and increased depth of field compared to conventional telephoto macro optics. Wide-angle prime is suitable for a variety of subjects, including landscapes, nature, and streets, and the close-focusing ability helps to home in on nearby subjects in between photographing broad spaces. The macro designation offers a 1:2 half-life-size maximum magnification and a minimum focusing distance of 5.5". Bright f/1.8 design offers both depths of field control and suits working in a variety of lighting situations. One UD (ultra-low dispersion) element and one aspherical element control both chromatic and spherical aberrations for well-corrected imagery that is especially sharp and color-accurate. Super Spectra coating has been applied to resist flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that benefits both stills and video recording needs. Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
