Who the Canon RF 24-240mm f/4-6.3 IS USM is for

The Canon RF 24-240mm f/4-6.3 IS USM is a full-frame 24-240mm f/4 standard zoom for Canon RF.

Best for

  • Wildlife, sports and distant subjects — reach to 240mm.
  • Everyday, travel and events — a versatile 24-240mm walkaround range.
  • Handheld stills and video — optical stabilisation smooths shake.

Keep in mind

  • Aperture tops out at f/4 — less low-light headroom and background blur than faster lenses.

What 24-240mm at f/4 actually gives you

24-240mm is wide enough to take in interiors, landscapes and architecture without the pronounced edge stretching of an ultra-wide.

f/4 is a moderate maximum aperture. There is less low-light headroom and less background blur than an f/2.8 lens gives, which is generally the trade for lower weight and cost.

Size, close focus and filters

At 750g (1.65 lb) it has real presence on the front of a camera, though it stays hand-holdable for a session.

Maximum magnification is 0.26x, enough for close-up work on flowers or detail shots without reaching genuine macro reproduction. It focuses as close as 50cm.

Filters are 72mm — worth checking against what you already own, since polarisers and ND filters at this size are reusable across any other lens sharing the thread.

Autofocus and stabilisation

Autofocus is driven by a Nano USM motor.

Optical stabilisation is built in, which stacks with in-body stabilisation on bodies that have it and does the work alone on bodies that do not.
