Canon RF 800mm f/11 IS STM Lens Review (by PhotographyBlog)

Posted on by

The Photography Blog has published the Canon RF 800mm f/11 IS STM Lens review (tested on the 30.3MP Canon EOS R): “Canon RF 800mm F11 IS STM is a refreshingly brave attempt to make an otherwise expensive branch of photography more accessible, both in terms of cost and portability”.

Canon RF 800mm f/11 IS STM Lens Key Features:

  • Focal length: 800mm
  • Maximum aperture: f/11
  • Canon RF-mount lens
  • Full-frame camera format
  • Up to 4-stops of shake correction with OIS
  • Lead screw-type STM
  • Gapless double-layer diffractive optics
  • 12-pin communication system
  • Control ring for direct setting changes
  • Compatible with optional FLEX 1.4x or 2.0x extenders

Conclusion from PhotographyBlog:

What’s not to like about a stabilized 800mm prime lens for full-frame cameras that is light enough to use hand-held, compact enough to travel with, focuses quickly and quietly with the minimum of fuss, blurs backgrounds with pleasing bokeh effects, and costs less than £$1000?

Well, there’s no getting away from that fixed f/11 aperture which limits its use to either bright conditions or high ISO speeds (or sometimes both), the lack of any kind of weather-sealing at all may well put off more hard-core users, the 6m minimum focusing distance is a little restrictive, the tripod mount can’t be rotated from landscape to portrait position, there could be some question marks over the long-term durability of the retractable design, and the essential lens hood is unfortunately an expensive optional accessory.

All in all, though, the Canon RF 800mm F11 IS STM is a refreshingly brave attempt to make an otherwise expensive branch of photography more accessible, both in terms of cost and portability – there simply aren’t any other 800mm lenses that are as inexpensive, compact and crucially as good as this one. Bravo to Canon for thinking out of the box.
