The optical designs shown in this patent application are slightly less complex than the VCM primes that we have seen released over the past few years, and sit around the same optical complexity as the existing RF STM primes.  It's hard to guess where Canon would be placing these lenses, but I would assume that these would be lower-end consumer-grade primes if ...]]>Tue, 07 Apr 2026 05:23:00 GMThttps://www.canonnews.com/a-modern-55mm-f18-canon-patents-new-batch-of-consumer-rf-primeshttps://www.canonnews.com/canon-patent-for-consumer-aps-c-rf-s-primes We have long wanted RF-S or Canon RF cropped sensor primes, and so far, at least, Canon has been resistant.  Fortunately for us, Sigma has released some excellent primes for Canon's RF-S cameras.  In this patent application ( 2026-052804 ), Canon shows us quite a few embodiments for cropped sensors. All of the designs rely on image stretching to fill the entire sensor, some of them quite significantly.  So I assume ...]]>Wed, 25 Mar 2026 05:15:00 GMThttps://www.canonnews.com/canon-patent-for-consumer-aps-c-rf-s-primeshttps://www.canonnews.com/canon-researches-a-crop-sensor-75-150mm-f4 This was a patent ( 2026-049828 )  that popped up recently, and I'm still getting back into the groove of reporting things "over here". It's a curious patent application that MAY have some use for an APS-C camera, if Canon decides to go all in on digital manipulation of the image to objectively produce a full APS-C-sized image circle. The image loss to the stretch in which we are seeing is only really relevant in the corners, and for ...]]>Mon, 23 Mar 2026 12:56:00 GMThttps://www.canonnews.com/canon-researches-a-crop-sensor-75-150mm-f4https://www.canonnews.com/canon-patents-a-rf-24mm-f12l-and-a-rf-35mm-f12l Canon continues its pace in the development of ultra-fast prime lenses for its RF mount. A recent patent application filing suggests that Canon is pursuing lens designs for its Canon RF 35mm f/1.2L and Canon RF 24mm f/1.2L lenses. This has sparked interest among photography enthusiasts regarding the possible imminent release of the much-anticipated "halo" lenses. Canon's latest patent application ( 2026-013481 , filed with the Japanese Patent Office) outlines the intricate lens designs ...]]>Thu, 29 Jan 2026 06:25:00 GMThttps://www.canonnews.com/canon-patents-a-rf-24mm-f12l-and-a-rf-35mm-f12lhttps://www.canonnews.com/canon-patent-application-improved-evf-technology This is a patent application ( 2025-070554 ) that describes another similar optical design, similar to the one we seen in the insanely fast and esoteric lenses we talked about before.  While it doesn't appear as if the technology is exactly the same, it's similar enough to lead me to think that all these applications and Canon's research is all connected. Canon mentions using these elements for EVF's and Head Mounted Displays.   This is basically Canon finding more uses for this rather ...]]>Sun, 04 May 2025 03:48:00 GMThttps://www.canonnews.com/canon-patent-application-improved-evf-technologyhttps://www.canonnews.com/patent-application-full-frame-zoom-lenses This is a curious patent application ( 2025-068535 ) because the lenses are all over the place.  I've seen these types of patent applications before and they always remind me of the designer just throwing optical designs at the wall to illustrate the patent purpose, without having an actual lens in mind for production.  There's a lens that would be more suited on the EF mount (but still too short for EF), and 3 other lenses that could be for the RF mount.  The inclusion of the first embodiment ...]]>Fri, 02 May 2025 04:46:00 GMThttps://www.canonnews.com/patent-application-full-frame-zoom-lenseshttps://www.canonnews.com/patent-application-full-frame-power-zoom-lenses In this patent application ( 2025-68536 ) we see that Canon is exploring power zoom full frame lenses.  While it's all together possible that Canon will take this patent application and make something out of it, it's usually not the case that we see optical design patent applications before the lenses actually come out.  Most times we see the patent application 2-3 months after the lens is released. So no clickbait here, but it's obvious that Canon is exploring more internally driven ...]]>Fri, 02 May 2025 04:14:00 GMThttps://www.canonnews.com/patent-application-full-frame-power-zoom-lenseshttps://www.canonnews.com/patent-application-canon-rf-s14-30mm-f4-63-is-stm-pz In this patent application ( 2025-050505 ), Canon describes lenses,  one of which appears to be the Canon RF-S14-30mm F4-6.3 IS STM PZ.  There has been some talk lately that lenses appear in patents before they are released, but this is more traditional: We  see the patent literature after we already have the lens. But with supply and logistics problems and Canon delaying product releases, every now and then, a lens will come out after we see the patent. But that's more of a rarity ...]]>Sat, 05 Apr 2025 15:21:00 GMThttps://www.canonnews.com/patent-application-canon-rf-s14-30mm-f4-63-is-stm-pzhttps://www.canonnews.com/canon-patent-quarter-wave-element-lenses In this patent application ( 2025-040503 ), Canon further explores this reflective and transmission phased layer to produce some wild lens designs.  I will have to come up with a name for this element, as I have a feeling we will see a lot of it. Now, it's still possible that Canon may never do these lenses with this layer, as we have no idea how difficult it is to mass produce. Look at the other patent application on some really esoteric ultra-wide lenses using this technique. All ...]]>Sat, 29 Mar 2025 14:41:00 GMThttps://www.canonnews.com/canon-patent-quarter-wave-element-lenseshttps://www.canonnews.com/canon-patent-esoteric-optical-designs This is an interesting patent application ( 2025-040484 ) from Canon describing some very strange yet unique lenses. Surprisingly, the lenses seem to be for fairly large sensors.  Usually, when we see patent applications like this, they are for smaller sensors (think 1" sensors). Canon mentions that with the explosion of small devices, drones, etc., there is more of a need for lenses that are compact, and very, very wide.  There's some lenses in here that are so wide, I think they break ...]]>Sat, 29 Mar 2025 14:06:00 GMThttps://www.canonnews.com/canon-patent-esoteric-optical-designs
