dpreview published their review of the Canon EF 200-400mm f/4L IS Extender 1.4x lens. They reviewed the lens together with the folks at DxOMark. Some excerpts from the conclusion:

  • […] it’s clear that the 200-400mm is exceptionally good
  • On full frame it’s near-flawless, and there’s practically no perceptible sharpness penalty for using the extender
  • AF with static subjects is very fast and extremely accurate
  • […] unique among top-end super-telephoto zooms
  • […] absolutely stellar optics and innovative design earn the lens our top award

The EF 200-400mm f/4l IS 1.4x got dpreview’s Gold Award. DxOMark says about the EF 200-400mm f/4L IS 1.4x:

[…] the Canon 200-400mm f/4L IS USM Extender 1.4X offers image quality that’s close to the best in class, along with the convenience and versatility that’s otherwise lacking with those fixed focal length equivalents.
