What Users Think

Pros

  • Incredibly lightweight at only 2.77 lbs, making it easy to handle for extended periods.
  • Affordable price point around $600-1000, providing an accessible entry to long telephoto photography.
  • Good autofocus performance, especially when using modern Canon cameras with improved tracking capabilities.
  • Decent image quality in good lighting, suitable for wildlife and landscape photography.
  • Great for capturing distant subjects such as birds and the moon, with many users reporting satisfying results.

Cons

  • Fixed aperture of f/11 limits low-light performance, requiring high ISO settings in less optimal lighting conditions.
  • Long minimum focusing distance of 20 feet makes it less suitable for close-up shots or smaller subjects.
  • Autofocus may be slower or less reliable for birds in flight compared to higher-end zoom lenses.
  • Limited versatility compared to zoom lenses; it requires precise aiming for distant subjects.
