Earlier this year, we saw a patent for a fingerprint sensor from Canon. Nikon has just taken things a bit further. The company has filed a patent for biometric sensors that will read a photographer’s emotions. They will be placed on the lens, as well as on the camera, to record your biometric information while you are shooting.
Well, this is interesting. I knew that most optical image stabilisation systems in lenses used electromagnetic fields in order to try and keep the elements steady. But what I hadn’t considered was how these fields might affect noise on the sensor and in the images. As it turns out, it affects them enough to warrant Canon developing a new system to help reduce it.
Remember when Huawei released the P9 and everybody got excited over its cameras because they had Leica written on them? And then there was the whole controversy over exactly how much involvement Leica had with their development? Well, it seems here we have another item bearing the Leica name with questionable origins. According to a patent recently filed by Konica Minolta, the $5,500 Leica Super-Vario-Elmar-SL 16-35mm f/3.5-4.5 ASPH lens is actually their design. Not Leicas.
A new patent spotted by Canon News shows a lens mount that looks similar to both Canon’s EF and EF-M mounts but is actually neither. The web translation of the patent is a little confusing. The patent seems to suggest, though, that this mount could be some kind of hybrid compatible with both full frame EF and EF-M mirrorless lenses.
Wireless charging seems to be the big thing with portable devices right now. There are various phones and tablets out there that support it, and as the technology evolves, companies are looking to see what other items can utilise it. Canon seems to think that cameras are one such possible device. At least if this new patent application being reported by Canon Watch is anything to go by.
Wireless charging certainly has its advantages, but it has some disadvantages, too. I just don’t know if it’s really going to be all that practical except in the most consumer level of devices that only see occasional use.
Canon has recently admitted that they are lagging in innovation behind other companies. Judging from that interview, there was no word about their plans related to photography. However, the company has recently filed a patent that lets you control your cameras and lenses using fingerprint detection.
Well, this is a surprise and not an unwelcome one. Few people seem to realise that as well as being a leading 3rd party lens manufacturer, Sigma also make cameras. I have actually had the pleasure of playing with a Sigma sd Quattro for the past few weeks, and it’s pretty impressive if a little on the slow side. The Foveon sensor does produce some truly beautiful results.
That lack of speed, though, has put off many potential Sigma camera owners. Now, a new patent has been filed showing that Sigma looks to be doing something about it. The patent seems to aim more toward the video side of things but no doubt it will speed up its stills capturing capabilities, too. Perhaps this is why Sigma semed a little evasive about camera questions recently at PPE.
A new Canon patent has recently been published which highlights a long-awaited feature. It shows what looks like a Canon 7D or 5D style body, with technology for illuminated buttons. It’s taken quite some time for Canon to catch up on this minor but important feature. Nikon have had it for years, and even Pentax have figured it out.
