Pros
  • solid casing of very high build quality,
  • excellent image quality in the frame centre no matter what focal length you employ,
  • very good image quality on the edge of the APS-C sensor,
  • good image quality on the edge of full frame,
  • slight chromatic aberration,
  • lack of problems with spherical aberration,
  • imperceptible distortion,
  • excellent coma correction,
  • moderate astigmatism,
  • imperceptible vignetting on smaller sensor,
  • nice blur areas,
  • silent and very accurate autofocus,
  • efficient image stabilization,
  • rich accessory kit.

Cons:

  • noticeable vignetting at longer focal lengths on full frame,
  • a bit too many flares (despite a huge improvement when compared to the predecessor).

I think those who were waiting patiently for the Canon EF 100–400 mm f/4.5–5.6L IS II USM won’t be disappointed. Its predecessor was optically very good but the new lens is better in every single category. The evenness of performance, no matter what focal length you use and what place of frame you take into account, is truly impressive. The lens remains sharp even on the edge of full frame and doesn’t have any resolution slip-ups. If you add to that the much-improved stabilization, a huge step forward when compared to the older model, you get practically a lens as close to perfection as it is only possible; its flaws, connected to vignetting and flares, aren’t anything serious. Our joy is dampened only by the price of the new Canon – over 3000 PLN higher than the price of its predecessor. However if you can afford it and you purchase it you will be happy with your decision. The Canon EF 100–400 mm f/4.5–5.6L IS II USM will not only guarantee sharp photos but also will be a joy to use.
