Here’s a fun patent from Canon – a lens that sucks. And I mean this quite literally. This lens incorporates a mini vacuum cleaner that cleans your camera sensor from dust.
A Canon patent has been discovered by the folks at Canon News showing what appears to be a camera with a “translucent mirror” reminiscent of Sony’s SLT cameras. But that appears to be where the similarity ends, as the Canon implements a whole second image sensor, which appears to help overcome dynamic range issues with existing cameras.
A new Canon patent has been discovered by the folks at Canon News. It describes an 83-megapixel sensor which, if the maths are right, will have the same pixel pitch as the 32.5-megapixel sensor in the recently announced Canon EOS 90D. A second 20.75-megapixel sensor has also been described in the patent
Judging from recent patent applications from Canon, we might see two new zoom lenses for the EOS R system: a 17-70mm and a 52-83mm f/1.2 lens. They both include multiple optical formulas, which could mean that we’ll see them in production in the future.
Canon is going wild with the patents lately, but there isn’t much as wild as this. Northlight Images spotted another Canon patent recently, for a somewhat insane Canon 50-80mm f/1.1 RF mount lens. This would not only be the widest aperture zoom lens Canon’s ever made but probably the widest aperture zoom lens anybody’s ever made.
This is something we’ve sort of seen before and Canon actually showed off a prototype for it back in 2015. But now a new patent has been granted to Canon, according to Canon Watch, for a new wireless charging system. With the catchy title “Power transmission apparatus for wirelessly supplying power to power reception apparatus”, Patent US10375639 describes a method of wirelessly charging cameras from a base station.
This is quite an interesting idea from Canon. I mean, photographers are often losing lens caps, especially if they shoot on location. You take off your cap, put it down somewhere, come back to it after shooting and suddenly, oh, where’s it gone? I’ve lost track of how many I’ve lost by now, to the point where I usually buy 5 at a time.
Canon’s new patent application (JP 2019-113645), though, describes a lens cap with a barndoor style configuration that allows you to open it up, shoot through it, and then close it again without having to take it off the lens at all.
The folks over at Fuji Rumors have come across a Fujifilm patent showing a compact camera with two rear dials that synchronise with a top LCD in order to create a pair of virtual dials that can be assigned to different camera functions. Unfortunately, they didn’t link to the actual patent, so we can’t dig any deeper into Fuji’s thought process behind it, but we can speculate.
One notable absence from Canon’s EOS R and EOS RP cameras is any form of in-body image stabilisation. Canon has said they wanted to bring it but didn’t feel it was quite ready, and that it would simply appear when it was. Now a new Japanese patent application (2019-087937) suggests that it is, and offers some clues as to how it works.
After Samsung announced that it is delaying the release of the $2,000 Galaxy Fold smartphone due to some pretty significant screen breakage issues, Dutch website Let’s Go Digital has discovered a new Samsung patent for a different kind of phone display.
This display is also sort of flexible, in that it wraps around the phone, however, this one does not fold and unfold. It’s essentially a double-sided phone with a single display that covers the entire front and then wraps around to cover about 3/4 of the back of the device.
