What Users Think

Pros

  • Surprisingly sharp across its range, especially for a superzoom lens.
  • Lightweight and compact, making it ideal for travel.
  • Excellent zoom range, covering from wide-angle to telephoto without changing lenses.
  • Fast autofocus performance that is especially effective for everyday photography.
  • Good image quality for casual use, often praised for its performance during daylight.

Cons

  • Variable aperture (f/4-6.3) limits low-light performance compared to constant aperture lenses.
  • Not weather-sealed, making it less suitable for adverse conditions.
  • Softness noted at extreme focal lengths, particularly when wide open.
  • Some users report the corners can be softer and more distorted.
  • Heavier than some consumer-grade lenses, making it cumbersome for all-day carry.

Community Verdict

Overall, the Canon RF 24-240mm f/4-6.3 IS USM is highly regarded as a versatile all-in-one lens that excels in convenience and decent image quality for travel and outdoor photography. However, its variable aperture and lack of weather sealing are notable drawbacks for those seeking high performance in low-light environments or challenging conditions.
