The Canon RF 15-35mm F2.8 L IS USM is a zoom lens for Canon RF (Full frame) that covers 15-35 mm at f/2.8, weighs 840 g and focuses as close as 0.28 m. Heaviest (840 g) of the 4 full frame Canon RF zoom lenses in its focal range. Among them, it suits you if you shoot in low light or want a blurrier background, or you want more reach at the long end. If you carry it all day or travel light, each other one that does better on weight gives up at least one of brightness and reach.

Worked out by code, not stated by a source

  • 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.

  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.
