For a lot of photographers, the 16-35mm f/2.8 is the wide-angle option of the Holy-Trinity of lenses. You could find this lens, (or something close to it), in pretty much every professional photographer’s gear bag you would speak too. Well back in February, Canon decided to up the bar once again by releasing it’s much-awaited Mirrorless version, the RF 15-35mm f/2.8 IS USM. Just like it’s other RF siblings in the trio, the R Mount lens brings next level sharpness edge to edge with no visible distortion when looking at real-world images, combined with a 5-stop image stabilization and fast f/2.8 constant aperture, it’s pretty much sure to be the key choice of wide-angle lens needs.

We held this lens at CES, and from our quick on site-testing, it looked incredibly sharp, had the beautiful image quality overall as is expected of L-glass, and the shorter balance is a delight to hand-hold! It is a little smaller than it’s EF glass equivalent, but does come with a pretty hefty price tag as the trade-off.

As of now, each of the lenses we’ve tested for the RF line of mirrorless cameras from Canon have genuinely outperformed all of their EF, so we’ve no doubt that once we get hands-on for a proper and full review with this lens it will be just as amazing.

Canon RF 15-35mm f/2.8L IS USM Lens Review from Gordon Laing



  • “Smaller” than the EF version
  • Image Stabilization
  • Fast Autofocus
  • Clean images edge to edge
  • No visible distortion


  • High price point
  • Even though it’s smaller than the EF, it’s still a very large and hefty lens

From what all of these sources say, the Canon Mirrorless RF 15-35mm f/2.8 L IS USM sets a new standard for what to expect out of the new mirrorless systems with the only real drawback being the higher price point. Bundled with a much faster autofocus, incredible image stabilization (that Canon users have been waiting for for ages!), and sharp images across the entire frame with no visible distortion, basically, if you’re a mirrorless shooter with Canon, this lens is a must-have!  Until we get to do our test of this lens, do you have any questions or concerns you’d like to see addressed in the review?
