Canon RF 100-500mm f/4.5-7.1L IS Review – Is It Really That Good?

Canon RF 100-500mm F/4.5-7.1L IS Review

Here is Canon RF 100-500mm f/4.5-7.1L IS review with some attention to bird photography. How good is this lens? The RF 100-500mm f/4.5-7.1L IS is an optical masterpiece by Canon, albeit an expensive one.

Key features:

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/4.5-7.1 to f/32-54
  • One Super UD Element, Six UD Elements
  • Dual Nano USM AF System

Jan Wegener posted his rather exhaustive Canon RF 100-500mm f/4.5-7.1L IS review. In his words:

500mm, small, light, and super flexible, sounds amazing, but can the new Canon RF 100-500 mm L IS USM deliver in the field? What about being wide-open at F7.1, is that gonna be a problem? For years I have been looking for a smaller bird photography lens that can compliment my F4 600mm prime lens. Will this finally be the lens that fits that role by delivering great image quality and the flexibility I need?

The RF 100-500mm is a remarkable lens, with many enthusiastic reviews.

Canon RF 70-200mm f/4L IS Review (the lens is a winner, D. Abbott)

RF 70-200mm F/4L IS Review

Here is a new Canon RF 70-200mm f/4L IS review. The Canon RF 70-200mm f/4L IS is getting quite popular with people on budget, or simply trying to safe some bucks.

At a glance:

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/4 to f/32
  • Four Ultra-Low Dispersion Elements
  • Air Sphere and Fluorine Coatings
  • Dual Nano USM AF System
  • Optical Image Stabilizer
  • Customizable Control Ring
  • Weather-Sealed Construction

Dustin Abbott posted his exhaustive Canon RF 70-200mm f/4L IS review. From his conclusion:

The Canon RF 70-200mm F4L IS USM is a winner.  It is incredibly compact, which opens up a whole new way to use the lens and a whole new market of those who wouldn’t mind the premium optics, build, and autofocus of an L series telephoto, but who were unwilling to deal with the bulk and weight of such a lens.  But Canon also has not compromised on the autofocus or image quality performance of this lens […]

The only area to criticize in this new design is that you have to give up the use of teleconverters, which is unfortunate when one considers that the amazing focus systems of the EOS R bodies (particularly the R5 and R6 at the moment) theoretically should make using TCs more seamless than ever before. This is a lens that must be used solely as the bare lens, though one could enable the 1.6x crop on a camera like the EOS R5 if you wanted more crop in camera.

[…] Autofocus performance is excellent. I really like Canon’s Nano USM tech, as it delivers fast, quiet, smooth, and accurate autofocus results. The image stabilizer is also effective even with a higher megapixel body like my EOS R5. I appreciate the solid image quality as well. But what really sets the RF 70-200 F4L apart is the incredibly compact, lightweight nature of the lens that will allow you to treat it like a 24-105mm F4 lens for transport and storage.

As usual Dustin’s reviews come with a huge set of sample pictures, comparison charts, and all the information you might want to know. Dustin’s reviews are what I look for when I am about to purchase new gear. And for those who prefer to watch their reviews, Dustin Abbott provides a comprehensive video-review.

For those in a hurry there is also a shorter version of the video review:
