Patent Application: Full frame and Super-35 Primes

Richard — Thu, 12 Dec 2024 11:12:48 +0000

In this patent application (2024-172507), Canon is showing off some prime designs for both full-frame sensors and some other embodiments for super-35. I’m not sure about the usefulness of the super-35 designs, but curiously, Canon is still creating embodiments for the format. All these lenses also have image stabilization, but they look rather simplistic, so [...]

Patent Application: Kit Zooms for both RF-S and RF

Richard — Thu, 12 Dec 2024 09:33:18 +0000

In this patent application (2024-173039), Canon talks about a few interesting wide-angle zoom lenses and one design, which I’ve seen a lot over the RF years and have wanted Canon to do. For me, a 17-70 or equivalent full-frame lens would be a “shut up and take my money” kind of lens as long as [...]

Patent Application: Canon Body Cap Style Lens Designs

Richard — Thu, 12 Dec 2024 08:56:18 +0000

In this patent application (2024-172505), Canon explores some very small lenses that are marginally longer than your standard body cap. These lenses could technically be used instead of a regular body cap, so you’d have a grab-and-go lens whenever you wanted to take a picture. Other manufacturers have made these, such as the 7artisans 18mm [...]

Patent Application: Canon RF Power Zooms

Richard — Thu, 28 Nov 2024 11:11:22 +0000

In this patent application (2024-166408), Canon looks to be investigating making some small power zoom kit lenses. Sony popularized this, and it would be interesting to see if Canon follows suit. The patent application intriguingly has both APS-C and full-frame lenses. If you notice that none of the embodiments have the image height. So if [...]

Patent Application: Super Telephoto Primes

Richard — Mon, 25 Nov 2024 10:17:27 +0000

In this patent application (2024-163673), Canon is exploring some lesser-quality super telephoto primes. Could be good news for us peons that don’t want to drop 5 digits on a super-telephoto prime. The designs seem interesting, yet simplistic, so I wouldn’t necessarily expect these lenses to cost that much. Canon RF 400mm F4.0 In this first [...]

Canon Patent Application: Canon Standard Zooms

Richard — Thu, 14 Nov 2024 07:13:05 +0000

One thing that Canon has done well with the RF mount is its normal zoom range with the likes of the RF 28-70mm f/2.0L, RF 24-70mm F2.8L, RF 28-70mm f/2.8 STM, RF 24-105mm f/4L, RF 24-105mm F2.8L, and finally the RF 24-105mm F4-7.1 STM. Whew. In this patent application (2024-160458) Canon is exploring the designs [...]

Richard — Fri, 08 Nov 2024 08:06:42 +0000

In a long list of related patent applications, we have yet another patent application (2024-157119) one that deals with Canon’s ever-growing body of research into automatically controlled and camera-adjusted tilt-shift lenses. Sooner or later these things will come out because, at this stage, research continuing across multiple years and not coming out would be a [...]

Patent Application: The Zoom You’ve Dreamt About: Canon RF 70-150mm f/2L IS USM

Richard — Fri, 01 Nov 2024 06:03:38 +0000

In this patent application (2024-154138), Canon hits the ground running on some downright jaw-dropping lovely zooms. Will we see any? I hope so, but I’m sure someone out there will complain about them being too expensive and too heavy. Going by the embodiments, these will be both. Canon sets up the problem domain that this [...]

Richard — Mon, 28 Oct 2024 09:43:09 +0000

In this patent application (2024-152935), Canon is researching some RF-designed super zoom embodiments. For those dying on that hill where super crazy zooms do not need to exist, you can stop reading now ;) These full-frame super zoom lenses were well used on the EF mount, as professional news and media photographers would use this [...]

Canon RF 200-500mm f/4L IS USM spotted in new patent application

Richard — Mon, 28 Oct 2024 09:12:24 +0000

In this patent application (2024-152941) Canon is researching some super telephoto zooms that are most likely some L’s. All these designs have internal zoom mechanisms and seem very well balanced, with most of the optical elements near the center or rear. Canon RF 200-500mm F4L IS USM This lens looks interesting and is certainly feasible [...]
