Canon working on weather sealed lens adapter, patent application suggests

Canon Patent

A few days ago we learned how well the EOS 5D Mark IV can cope with water. It’s just natural we found a Canon patent application for what appears to be a weather sealed lens adapter (EF/EF-S to EF-M, is my guess).

Canon patent application EP20170178735 describes a lens adapter which is protected against dust, water, whatever.

The present invention provides a technique that ensures reliability of an electric connection between a lens adapter and an apparatus body with a simple configuration even when a spacer is inserted between the lens adapter that has an electrical communication unit and the apparatus body of an image pickup apparatus. Moreover, the present invention provides a technique that ensures a dustproof performance between the lens adapter and the apparatus body of the mage pickup apparatus even when the lens adapter has the electrical communication unit.

According to the present invention, the reliability of the electric connection between the lens adapter and the apparatus body is ensured with the simple configuration even when the spacer is inserted between the lens adapter that has the electrical communication unit and the apparatus body of the image pickup apparatus. Moreover, according to the present invention, the dustproof performance between the lens adapter and the apparatus body of the mage pickup apparatus is ensured even when the lens adapter has the electrical communication unit.

I’d love to know what exactly this lens adapter is for. Is it the next iteration of the already existing EF/EF-S to EF-M adapter (), or has it something to do with Canon’s upcoming full frame mirrorless camera which is rumored since a while? Any help is welcome, patent literature is difficult to read.

canon patentPatent applications filed by a company do not necessarily mean the described technology will hit the market any time soon. Patents are a way companies have to protect their intellectual property and research. Some Canon patent applications that in our opinion might indeed go into production are these:

Canon Inc. leads US patent applications again, 32nd consecutive year

canon rumors

Well, it’s the camera and lens manufacturer we love for their reliable gear, and we all know how diligent they are in filing patent applications. I’ve some doubts about the “innovation” aspect, though.

Press release:

Canon’s Focus on Innovation Once Again Lands Imaging Leader a Top Five Spot Among U.S. Patent Holders for 32nd Consecutive Year

Company claims third most U.S. Patents, placing it ahead of fellow tech giants globally.

MELVILLE, N.Y., January 10, 2018 – As part of its mission to redefine the boundaries of innovation and expand the possibilities of imaging technology, Canon U.S.A., Inc., a leader in digital imaging solutions, has announced that its parent company, Canon Inc., based in Tokyo, Japan, ranks third among U.S. patent holders in 2017.

According to patent results issued by IFI CLAIMS Patent Services, a leading producer of global patent databases, Canon was granted a total of 3,285 patents in 2017. This is the 32nd consecutive year that Canon Inc., has been ranked among the top five U.S. patent holders and for the 13th consecutive year, ranked first among Japanese companies for the number of U.S. patents granted. The patents granted demonstrate the company’s commitment to using a robust set of intellectual property rights to develop visionary consumer, business and medical solutions.

“Having landed once again among the top three patent holders, Canon’s longstanding and continued commitment to strategic research and development through continued innovation is evident,” said Seymour Liebman, executive vice president, chief administrative officer and general counsel, Canon U.S.A. Inc. “With 3,285 patents to our name, Canon is immensely proud of our strong standing among fellow tech giants as we continue to cement our role as a worldwide leader in imaging solutions in 2018 and beyond.”

In 2017, Canon U.S.A. imaging IP and technology innovation has earned Emmy recognition for its 4K cameras and lenses and opened up new research opportunities for wildlife habitats in the dark with its low light camera, the ME20. Ripples of Canon’s technological advancements were also felt in the production printing industry, where the company unveiled breakthrough new technology such as the Océ Colorado 1640 wide format printer, powered by Canon’s UVgel technology, which is the world’s first 64-inch roll-to-roll printer.

The patent news also comes on the heels of Canon’s innovation showcase at the 2018 Consumer Electronics Show (CES) where its “Visionaries Welcome” themed-booth featured previously-patented technologies integrations in manufacturing, retail, sports and entertainment and experiential marketing solutions.For more information on Canon and its products, please visit

Weather Sealing Torture Test: Canon EOS 5D Mark IV does great, Sony A7R III not so much

Eos 5d Mark Iv

The folks at Imaging Resource decided to put four cameras through a weather sealing endurance test.

The tested cameras are the Nikon D850 (), Sony A7R III (), Canon EOS 5D Mark IV (), and the Olympus E-M1 Mark II (). Canon and Olympus did best, Nikon had some issues, and Sony showed once more  that their gear is as innovative as it is immature (i.e. in beta stage). Enjoy.

From Imaging Resource’s conclusion:

[…] we were sad to see the A7R III have such a hard time in this test. It’s a fantastic camera, absolutely at the cutting edge of what’s possible with photographic technology today. […]  Sony needs to up their environmental-sealing game if they want to compete in this high-end/professional market segment. We’d feel differently if all the cameras failed the test; we would have concluded that the test was just too harsh for the current state of the market, even though it was a reasonable representation of conditions a camera might be exposed to. That wasn’t the case, though; the D850 had a very minor problem with leakage into its viewfinder, that seems to be entirely solved by using the BS-3 hot shoe cover – and the 5DIV and E-M1II had no problems whatsoever.

Peter McKinnon had an issue with his Canon EOS-1D X Mark II (price & specs): the internal housing of the microphone input cracked and broke. Reason enough to send the EOS-1D X Mark II to Canon support asap. But Peter first wanted to know what’s inside this professional, $6,000 DSLRs. Have a look and do not get into temptation to do it to your camera.


The Canon Powershot Pro1 is the only PowerShot with an L-grade lens

Powershot Pro1

Canon PowerShot Pro1 at a glance:

  • 8MP sensor
  • 7x optical zoom (28-200mm equivalent)
  • f/2.4-3.6
  • Auto, Scene Program, Program, and Manual exposure modes
  • tilt/swivel LCD panel
  • EVF/LCD works down to very low light levels

Before you get excited: The Canon PowerShot Pro1 was released 13 years ago. However, it’s the only PowerShot camera Canon ever released featuring a L-grade lens (see the red ring?).

The folks over at The Camera Store TV posted a 11 minutes video review of the PowerShot Pro1. Chris Niccolls got a PowerShot Pro1 in his hands and wants to see what features are still compelling, and which are hopelessly out of date. Enjoy.

Some more bits about the Canon PowerShot Pro1 (source: Wikipedia):

[the PowerShot Pro1] was the most expensive fixed-lens camera sold by Canon at the time, and thus the top of the PowerShot range. It was the first fixed lens designated a Canon L series lens, a designation normally reserved for expensive EF-series SLR lenses.

It has a variable-angle two-inch, polycrystalline silicon, thin-film transistor, color liquid crystal display with approximately 235,000 pixels and a colour electronic viewfinder (EVF) with the same resolution. The lens has a 35 mm equivalent zoom range of 28 to 200 mm. The shutter has a maximum speed of 1/4,000 second. The camera’s dimensions are 117.5 mm in width, 72 mm in height, and 90.3 mm in depth. Its mass is 545 g.

The PowerShot Pro1 was announced in August 2004, and then sold for $999. I found Canon’s press release for the PowerShot Pro1, you can read it after the break.
