Canon RF 15-35mm F/2.8L IS Review

Canon RF 15-35mm f/2.8L IS review by Photography Blog.

The Canon RF 15-35mm f/2.8L IS is one of the “holy trinity” lenses for the EOS R system. A lens that’s not for everyone’s budget.

From the conclusion of the Canon RF 15-35mm f/2.8L IS review:

This lens is lovely and sharp, while also being very good at keeping distortion to a minimum. W’ve been using it with a Canon EOS RP, which arguably is not the best camera to use it with. But even the 30 megapixel Canon EOS R probably wouldn’t even do it justice – perhaps Canon will be announcing something with an ultra-high resolution sensor targeted more squarely at professional users than the existing line-up some time soon.

[…] Image quality from this lens is fantastic and if you’re somebody who has a need for an ultra-wide-angle lens for the Canon full-frame mirrorless system, it’s hard to deny just how excellent it is.

Canon Patent

If we believe the sheer number of Canon patent applications for RF lenses we must think Canon takes their EOS R full frame mirrorless system very seriously.

Canon patent application 2019-197095A (Japan) discusses the optical formulas for three very fast prime lenses for the RF mount. The lenses are 18 mm f/1, 18mm f/1.2, and 25mm f/1.2. 

  • Focal length: 18.51mm
  • F no: 1.24
  • ω : 49.45
  • Image height: 21.64mm
  • Lens length: 129.00mm
  • Back focus: 16.40mm
  • Focal length: 24.59mm
  • F no: 1.24
  • ω : 41.35
  • Image height: 21.64mm
  • Lens length: 129.01mm
  • Back focus: 13.57mm

  • ω : 49.47
  • Image height: 21.64mm

How To Do Autofocus Microadjustment On Your Lens (tutorial)

Autofocus Microadjustment

Here is something useful. A video about hot to do autofocus microadjustment.

The 14 minutes video below by Michael The Maven shows how to microadjust autofocus on your lens using a cereal box and a ruler. He uses a Canon EOS 90D to show it.

The cereal box and ruler method allows photographers to quickly visualize where their lenses are focusing and to verify if they are out of alignment. This video demonstrates the philosophies of MFA (micro focus adjustment) and some of the principles to become familiar with if you decide to try this on your own.

If you prefer there is a neat written tutorial about how to do autofocus microadjustment by Canon itself and you can download it here.
