Patent Application: Canon RF-S14-30mm F4-6.3 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 than a rule. The only certainty we have with a patent application is that they are actually working on designs in the ballpark of what is shown in the patent application. Another patent application, Patent Application 2024-072459, was filed last year. It also had some similar designs, but none that matched up well to the actual production lens. Embodiment 4 - Canon RF-S14-30mm F4-6.3 IS STM PZ There are a lot of variations in the embodiments, but here is the embodiment showing the Canon RF-S14-30mm F4-6.3 IS STM PZ. If you look closely, you'll see that the elements are the same between the two images, with the one on the right, from the Canon Japan website, being the actual lens. From this, we can see the actual lens data derived from the optical design. Wide-Angle MIddle Telephoto Focal Length 14.41 20.03 29.35 F-Number 4.08 5.18 6.43 Half Angle Of View 40.33 33.59 25.69 Image Height 12.24 13.31 14.12 Lens Length 80.14 80.14 80.14 Back Focus Distance 14.20 14.20 14.20 This lens does certainly has some image stretching, as it doesn't necessarily reach the 13.66mm for a full image circle projection. But with the lens priced at around $329, and even less if you purchase it bundled in with the Canon EOS R50 V, it should be expected that some compromises were made in the lens.
