Overview

The Canon EF 100-400mm f/4.5-5.6L IS II USM is a staple in the kit bags of sports and wildlife photographers who need reach without sacrificing image quality. Its 100-400mm zoom range covers everything from tight sideline action to distant birds in flight, and the inclusion of one fluorite and one super UD lens element ensures chromatic aberration is kept to a minimum across the entire range. The result is images with impressive resolution, contrast, and color accuracy — hallmarks of Canon's L-series optics. A nine-blade aperture diaphragm produces smooth, pleasing background blur, helping subjects stand out from their environment.

Practical shooting benefits are equally strong. The Optical Image Stabilizer provides up to four stops of correction, making handheld shooting viable even at 400mm, while the close 3.2-foot minimum focus distance opens up macro-like detail work uncommon in this class of lens. As a renewed unit, this lens has been manufacturer refurbished to meet original performance standards and ships with all original accessories and a full warranty, offering a cost-effective way to add professional-caliber super-telephoto capability to your Canon system.

Key Features

Compact, high performance L-series super-telephoto zoom makes it ideal for sports and wildlife photography.

One fluorite and one super UD lens element provides excellent correction of chromatic aberration throughout the entire zoom range, helping to deliver high-quality images with high resolution and contrast.

Optical Image Stabilizer provides up to four shutter speed steps of correction. --According to CIPA standards (400mm focal length, when using the EOS-1D X).

Pros & Cons

👍 Pros

  • Covers a versatile 100-400mm zoom range in a single lens, reducing the need to swap glass in the field.
  • Fluorite and super UD elements deliver sharp, high-contrast images with minimal chromatic aberration.
  • Four-stop optical image stabilization supports handheld shooting at long focal lengths.
  • L-series build quality with weather sealing stands up to demanding outdoor conditions.
  • Close minimum focus distance of 3.2 feet allows detailed close-up shots of wildlife and nature.

👎 Cons

  • Variable f/4.5-5.6 aperture limits low-light performance compared to fixed-aperture telephoto primes.
  • At approximately 3.5 pounds, extended handheld use can be fatiguing during long shoots.
  • Renewed condition means cosmetic wear may be present, even if functionality is fully tested.
  • EF mount only — mirrorless Canon R-system users will need an adapter for full compatibility.
