24 Canon RF 24mm F1.8 MACRO IS STM

The Canon RF 24mm F1.8 MACRO IS STM is a prime lens for Canon RF (Full frame) that covers 24 mm at f/1.8, weighs 270 g and focuses as close as 0.14 m. Next to 3 other full frame Canon RF prime lenses in its focal range, it suits you if you carry it all day or travel light, or your body has no in-body stabilization or you shoot handheld video. If you shoot in low light or want a blurrier background, every other one that does better on brightness gives up weight and stabilization.

Worked out by code, not stated by a source

  • Focal length and widest aperture as the lens's own name states them.
  • Read from the lens name: each maker marks the sensor size a lens covers (Sony FE/E, Canon RF/RF-S, Nikon DX, Tamron Di III/Di III-A, Sigma DG/DC); every Fujifilm X lens is APS-C and every Micro Four Thirds lens is Four Thirds.
  • Prime or zoom, read from the focal length in the lens name.

How the pick works

  1. Widest aperture3

    Lower wins once they are 0.3 apart.

  2. Weight2

    Lower wins from a 12% gap.

  3. Focal length (longest)2

    Higher wins from a 15% gap.

  4. Focal length (widest)2

    Lower wins once they are 2 mm apart.

  5. Optical stabilization1

    Having it wins.

  6. Closest focus, wide end1

    Lower wins from a 15% gap. Compared only between lenses of the same focal length (widest).

  7. Filter thread0.5

    Lower wins once they are 5 mm apart.

  8. Lead for a pick1

Our pick or our take adds up the importance of each real difference, with these importances and thresholds: a gap smaller than its row's threshold is too close to call and counts as the same. They are our editorial choice, not a measurement, the same on every page, and they never read prices, sales or who sells it.
