Canon Just Patented Its Most Insane Lens Ever

Canon has lengthy been recognized for pushing the limits of lens design, however their newest patent is excessive, even by way of their requirements. 

A brand new patent submitting hints at an bold soar in lens design: a 24mm lens with an f/0.7 aperture. This mixture of ultra-wide and ultra-fast is unusual, most often hindered by way of measurement, weight, value, optical compromises, and just about no matter else you’ll be able to recall to mind.

According to Canon Rumors, this intriguing construction stems from Canon’s patent software JP 2025-040484, which outlines a compact optical device aiming to merge a large box of view with an exceptionally massive aperture. Historically, lenses just like the Zeiss Planar 50mm f/0.7—at first advanced for NASA’s Apollo missions and later utilized by Kubrick in “Barry Lyndon”—have accomplished such apertures, however at longer focal lengths. A 24mm lens at f/0.7 can be exceptional, probably providing photographers and filmmakers new ingenious probabilities in low-light situations.

Achieving this design comes to overcoming vital technical demanding situations. Wide attitude lenses at such apertures steadily be afflicted by problems like coma, box curvature, and focal point respiring. Moreover, the shorter flange distance in mirrorless digital camera methods leaves much less room for inner lens parts, complicating the design additional. Canon’s patent suggests answers to those issues, together with cutting edge use of inner focusing teams to attenuate composition shifts throughout focusing.

While the patent demonstrates Canon’s dedication to pushing optical barriers, it’s a must to observe that no longer all patents lead to industrial merchandise. Frankly, I’d be extremely stunned to peer an f/0.7 lens, however possibly Canon is seeing how a long way they may be able to push issues to discover a Goldilocks lens within the heart — possibly f/1.0? We’ll see.
