Ultra-wide lenses require big, heavy glass. That’s even more true for zooms, which can easily begin to approach the weight of a telephoto. But the new Canon RF 14-35mm f4 L IS USM weighs just over a pound, and includes stabilization. With the L in the name and a $1,699 price tag, however, Canon’s new ultra-wide mirrorless lens has a lot to live up to.
I spent some time photographing fall landscapes with the Canon RF 14-35mm f4 L IS USM on the EOS R6. With excellent sharpness and stabilization, this lens might just be a landscape lover’s dream. That price, however, may be a sticking point.

Too Long, Didn’t Read
The Canon RF 14-35mm f4 L is lightweight and well-built. There’s little to complain about in the autofocus and stabilization performance. It captures stunning JPEGs, but also captures some significant corner bending vignetting at 14mm that’s going to need lens profile corrections (not yet supported in Lightroom or Capture One as of writing this review).
Canon RF 14-35mm f4 L IS USM Review Pros and Cons
Pros
Compact and lightweight
Weather-sealed
5 stops of stabilization, 7 with IBIS bodies
Extra control ring
Beautiful color
Close focusing capabilities
Cons
$1,699
Some correction needed for RAW files for barrel distortion and vignetting
Control rings can be hard to differentiate at first
Gear Used
I paired the Canon RF 14-35mm f4 L with the EOS R6. I used this set-up primarily for landscapes.
Innovations
Ultra-wide optics tend to be either stabilized or lightweight, but not both. The Canon RF 14-35mm f4 L has 5.5 stops of stabilization, or 7 with IBIS bodies, yet only weighs 1.2 pounds. Comparatively speaking, there’s not really a lens like it. There are other ultra-wide zooms, but none have this mix of stabilization and portability.
