Canon EOS R5 Review For Underwater Photo And Video

Canon EOS R5 Review

Canon set a new reference standard with the Canon EOS R5, overheating drama included. Here is a Canon EOS R5 review for underwater photography and video.

Coming from the folks at Bluewater Photo Store, the video below is…

[…] a full review of the Canon EOS R5 full frame, 45 megapixel mirrorless camera for underwater photo and video. The R5 has some of the best specs on the market including 45 MP still images, 8K video @ 30P with internal RAW recording, 4K video up to 120fps, 5 axis in-body image-stabilization, and more!

The staff at Bluewater Photo and the Underwater Photography Guide took the Canon EOS R5 diving in the cold waters of the Puget Sound, Washington to put it to the test and see just what it could do. We’ve been very impressed with the underwater footage that we captured. However, we do think that the marketing by Canon for the R5 should have been done differently – this is a spectacular still camera with amazing video features, but it should not be relied on for the video features that were initially marketed.

Well, at least underwater the heating issue should be under control ;-)

The EOS R5 seems to be highly regarded as a stills camera. In particular, the EOS R5 autofocus system seems to be huge leap forwards. More Canon EOS R5 review stuff is listed here, for the EOS R6 see here. User manual are available for download for the EOS R5 and the EOS R6. My opinion about the EOS R5 overheating hysteria is listed here.

Industry Rumors: Leica To Release A James Bond-themed Limited Edition Camera


In a clear effort to uncover new ways to motivate people to waste spend $5000 for a camera with Sony sensor, Leica will soon release a special edition, James Bonde-themed camera. How can you afford not to own one?

The Leica Q2 007 Special Edition will be released in the next weeks. Here are some images leaked ahead of the announcement. Is the suitcase a fancy camera case or a suggestion about how to take the money to the retailer?

Friday Hacker Blogging: The History Of Unix and Linux

History Of Unix

Front Page Linux posted an interesting and well written article about the history of Unix and Linux. Definitely worth your attention if you are into computer science.

For this special history guide, we are going to take a trip back in time to see where the seed of Linux was planted — namely via the Unix systems of the early 1970s and how it has progressed through the modern day. Though most are completely unaware of the enormous impact that Unix-like operating systems have planted on our society, understanding its storied history can allow us to realize why the Unix model has lived on far longer and become more successful than any other operating system architecture (and philosophy) in existence.

In fact, the estimated 5 billion people in the world (more than half the population) to own a mobile phone have been using Unix-based operating systems, knowingly or not, since the “smart” phone hit the consumer shelves in the late 2000s. From the Linux-based Android platform to the BSD-flavored iOS, Unix has stolen the massive mobile market along with the majority of other systems in existence. In fact, if you look at the operating system on just about any device besides the desktop PC, it is more likely than not that it runs some form or derivative of Unix.

So, how did an operating system written to port a game from one machine to another gain so much prominence in our world today when it was first conceived and implemented over sixty years ago? Well, our journey begins at AT&T’s famous Bell Laboratory with two unlikely heroes that helped kick off the modern technological age. Strap in and grab some popcorn, this is going to be a wild ride!

Canon Bought A Fujitsu FX1000 Supercomputer To Speed Up Product Development

Canon got themselves a Fujitsu FX1000 Supercomputer System.

Press release:

Fujitsu to Deliver New FX1000 Supercomputer System for Canon

TOKYO, Sept. 22, 2020 — Fujitsu Limited today announced that it has received an order for a new supercomputer system from Canon Inc.

The system consists of a Fujitsu Supercomputer PRIMEHPC FX1000 unit, which harnesses top-class technology from the world’s fastest supercomputer, Fugaku, which was jointly developed by RIKEN and Fujitsu. The new supercomputer will achieve an expected theoretical computational performance of 648.8 teraflops.

Upon completion, the supercomputer will play a key role in contributing to Canon’s initiative of “no-prototype” product development, delivering enhanced capabilities and scope of applicability of analysis in Canon’s product development process.

This system is planned to begin operations in the first half of 2021.


Canon is promoting a “no-prototype” initiative in the development of its products, such as office multifunction devices and other various types of printers, cameras, and semiconductor lithography equipment. To make this initiative a reality, Canon is leveraging 3D CAD data in analytical simulations to evaluate multiple facets of proposed products, including functionality, as well as ease of manufacturing. In the past, Canon has relied on both a Fujitsu Supercomputer PRIMEHPC FX10 system and a Fujitsu Supercomputer PRIMEHPC FX100 system.

Now, to take its initiative to the next level, Canon has adopted Fujitsu’s PRIMEHPC FX1000 system, which delivers reliable, high performance computing power, with world-leading energy efficiency.

Overview of the New System

Fujitsu’s new system consists of a PRIMEHPC FX1000 with 192 nodes, with an expected theoretical computational performance of 648.8 TFLOPS. Fujitsu will also deploy Fujitsu Server PRIMERGY systems and Fujitsu Storage ETERNUS systems as peripheral devices. As an important part of Canon’s product development cycle, this system will enable larger scale analyses and simulations in impact analysis experiments evaluating damage to or deformation of a potential product when dropped, including simulations with over 100 million elements, a challenge for previous systems to handle. The new system will also support airflow analysis and electromagnetic wave analysis. These benefits will ultimately help to deliver an enhanced product development flow through Canon’s “no-prototype” initiative.

Fujitsu’s technical computing solutions, particularly the PRIMEHPC FX1000, demonstrate an ongoing commitment to streamlining the performance, quality, and functionality of products while reducing product development times and costs for its customers.

Major Components of the New System

Upcoming Canon RF 50mm f/1.8 STM Lens Shows Up At Certification Authority

Canon Rf 50mm F/1.8

We knew Canon was working on a Nifty-Fifty for the EOS R camera system. Now the Canon RF 50mm f/1.8 showed up at a certification authority.

Two lenses with SKUs 4514C005 and 4515C005 have been registered, and it seems 4515C005 refers to the upcoming Canon RF 50mm f/1.8 STM. The lens already got rumored, and a pertinent patent was spotted.

The Canon RF 50mm f/1.8 STM was rumored to get announced in 2020 but it looks as if it will come in 2021 unless Canon does another announcement session this year, which seems unlikely. And the other registered lens…?

Canon Mount Adapter EF-EOS R 0.71x Speedbooster Explained

EF-EOS R 0.71x

Here is a short video introducing the new Canon Mount Adapter EF-EOS R 0.71x, a speedbooster-like adpater to mount EF lenses on RF mount cameras. The Mount Adapter EF-EOS R 0.71x was announced along with the Canon EOS C70.

From Canon:

This adapter converts light transmission from full-frame to Super 35mm image format. It extends the angle of view and optical sensitivity, while seamlessly integrating with the camera’s optical corrections. mount adapter.

In addition to the flanges of the RF mount, four screws securely attach the adapter to the camera. Once mounted, the adapter maintains a similar angle of view of your full frame lenses on the Super 35mm sensor, while boosting the speed of the attached lens by an average of 1-stop. The adapter also carries all EF information through to the RF contacts, so on certain lenses, full DPAF and metadata will be available, working much as they do on a native EF mount.
