In this test, we will probe my Canon EOS R5’s actual internal temperature in Celsius, as reported by the firmware. Is overheating real or fake? CDA-TEK and I are developing a Temperature Status Monitor app for the Canon EOS R5. It connects to the camera via the Canon API over Wifi from an Android device. This official Canon API was released by the company so that app developers can create remote control apps and monitoring software for EOS cameras (it isn’t a hack). With the commands that Canon themselves have implemented, one can read the status of the EOS R5 …

UPDATED: Chinese user modifies Canon EOS R5 to improve heat management, but finds artificial firmware time limit

A Chinese user/engineer disassembled the Canon EOS R5 with the aim of studying overheating. The hardware is laid out in such a way to trap heat around the CPU. In a Baidu post detailing the teardown here in Chinese, we see a detailed inspection of the EOS R5 hardware. Thanks to “AndroidLad” on the EOSHD Forum for the find. The EVF panel is Sony’s “ecx339a”, it has a thermally conductive material on the back. Surrounding the main image processor are four high speed memory chips (LPDDR4 3733), these also have thermal pads to conduct heat away. Immediately you notice something strange. …

I bought a Canon EOS R5 and it overheated in the Wifi menu! ALSO: a look at potential solutions

At the weekend I bought the enigma that is the EOS R5 for myself. Foto-Meyer in Berlin were able to find me a rare unit. What all EOS R5 owners have in common is that they have paid a lot of money for a professional video tool. We pay the money, we get to decide what happens next, and I’ll be reaching out to Canon and making this clear. We need to ask them to work on a solution for overheating. It’s worse than you can possibly imagine. Just need to get something straight – my purchase is NOT an …

Sony A7S III heat absorption problems in direct sunlight

When does a heat dissipating structure become a heat absorption structure in direct sunlight? There are now a few confirmed reports by the first Sony A7S III reviewers that the camera has an overheating problem in bright midday sun. The Sony A7S III reviews have been mainly positive, thanks to the superb job Sony’s PR department did on buttering people up. But the truth is usually somewhere in between. I have no first hand experience of the camera because Sony’s marketing department is full of exactly the kind of chinless wonder’s you’d expect in cahoots with social media starlets. With …

The real-world 4K HQ overheating limit is 2 minutes on the Canon EOS R5 say DPReview


This post is by Andrew Reid (EOSHD) from EOSHD.com - the DSLR video and digital filmmaking blog


Click here to view on the original site: Original Post




The Canon EOS R5 must be recalled now as this is so far from acceptable. It appears that only 1-2 hours into a stills shoot you can toss aside the Canon overheating test data in the real-world. In an update to the test at DPReview, Richard Butler found this out the hard way as he describes below. The real story is not the continuous recording cut off at 30 minutes from cold in normal room temperatures, but that the limit is closer to 2 (or even zero) minutes during a day’s real-world shooting. I’ve been saying for a while – …

Is this the new Komodo-style $4500 Canon mini Cinema EOS camera?

Some say Canon already have a fire-breathing small dragon in the EOS R5, but an official “Canon Komodo” mini RF mount Cinema EOS camera might indeed be planned for an August unveil if Canon Rumors are right. Interestingly, if you look back around 10 months to a Canon mini cine camera patent, the company can be seen to be already developing a very small Cinema EOS camera with active cooling system and Komodo-style form factor. However in the patents, the feature-packed body is for a camera with XC10 style fixed lens. So this may point to there being two versions – one

Canon UK on EOS R5: “shoots comfortably on high-end production sets – ideal partner to C300 Mark III” – Why overheating is unintentional

Canon C300 III / EOS R5

Back in April, Canon announced the video specs of the EOS R5 with much hubris. The camera was indeed intended to shoot reliably in 8K and 4K alongside Cinema EOS cameras… According to Canon themselves. So I don’t think Canon intended the EOS R5 overheating to be a purposeful cripple hammer. I think all the signs point to it being a major engineering cock-up. In the Canon UK press release dated April 20th 2020, the company says: “On the set of high-end productions such as commercials, dramas and documentaries, the EOS R5 is an ideal partner to the likes of …

DPReview has released their Canon EOS R5 and R6 test of overheating, using the final production models. Technical editor Richard Butler remarks “Lack of dependability makes them a poor choice for much professional video work”. There are areas of this test that I agree with, and other parts I don’t. But that’s ok, people can have differences of opinion and I’ll put my cards on the table about this now. Richard says the EOS R5 is not marketed at professionals interested in video: “It should be noted that Canon did not design either the EOS R5 or R6 to be …

The Canon EOS R5 is a faulty product. If you are order an EOS R5, please consult the field tests and data below to determine how it performs in the real world. Important: there is no hard and set recording time limit that always applies to 4K HQ and 8K. You do not have to film in 30 or 20 min continuous takes to trigger the overheating warning. Just having the camera switched on or taking a few photos reduces the limit on a hot day to as little as zero minutes of video recording. Therefore the Canon EOS R5 …

Severe Canon financial results see profits drop 93% (COVID-19) – Recalling the EOS R5 would be the ETHICAL thing to do

Profits at Canon’s camera division were down 93.8% year on year in Q2 2020 due to COVID-19. The 3 months ending June saw lockdowns and a global pandemic take hold across the world. The loss of life and livelihood is the important and most sad aspect of 2020, indeed the saddest time in my lifetime. My heart goes out to anyone who is mourning the loss of a loved one or suffering from a lack of work and derailed plans. In this article though I’d like to focus on Canon’s dire financial results from Q2 and the impact of

Is the lemon a goner?! As a journalist and filmmaker I like to find out the stories behind the scenes, and when it comes to a big camera launch like the Canon EOS R5, it is interesting to get an idea of how popular it is by speaking to retailers, how many pre-orders there are and how many units are in the first shipments. I have done this a lot over the past few years and now have a wide spread of sources for my information in the UK and Europe. Here’s what they told me today about the Canon …

Panasonic S1H to Atomos Ninja V 6K ProRes RAW update now available to download

Panasonic S1H owners today can start recording in high-end cinema camera standard 6K 12bit ProRes RAW via HDMI to the Atomos Ninja V. Unlike many ProRes RAW HDMI outputs this one is a full pixel readout from a native 6K sensor, with dual gain circuitry and incredible low light performance. Most cameras have to pixel bin to achieve 12 bit colour depth in their 4K RAW outputs from a higher resolution sensor, but not the Panasonic S1H. This should result in the cleanest and best ProRes RAW output on the market. Download the ProRes RAW firmware for no extra cost, …

As a Fuji GFX 100 owner I say “NOPE” to both the Sony A7S III and Canon EOS R5

Comment on the forum Canon and Sony seem ready in the middle of a severe pandemic to want thousands of bucks from me. If I review the Canon EOS R5 and Sony A7S III they will be returned to Amazon afterwards. Because fundamentally, I can’t align myself with the values of either corporation and as a medium format 10bit 4K user, I am unwilling to sacrifice the larger sensor and more cinematic look of the Fuji GFX 100 for an overheating pocket hand-warmer and a 3-year late Sony mirrorless camera. Sony A7S III versus Canon EOS R5 versus COVID-19 There …

Sony A7S III is here – Sensible update but not as revolutionary as hoped, plus tough competition from Panasonic S1H

Click here to view on the original site: Original Post




5 years after the previous A7S, the new model sees Sony playing catch up in some ways, having made users wait many years for 10bit recording on a mirrorless camera. The Panasonic GH5 has had 10bit since 2017 – 3 years ago. We have waited even longer for Sony to reorganise their menus! With the A7S III, they have finally implemented a Panasonic / Fujifilm style menu but the results don’t look aesthetic. The Sony A7S III was promised to be “revolutionary”, an “everything is new” camera. I’d say it is more like an “everything is tweaked” camera, but I …

Opinion: Canon EOS R6 and R5 heat problems risk full product recall, class action lawsuit


This post is by Andrew Reid (EOSHD) from EOSHD.com - the DSLR video and digital filmmaking blog


Click here to view on the original site: Original Post




Canon are marketing the EOS R5 and R6 as reliable filmmaking tools that professionals can depend on during a shoot. As we have seen from field-tests of both cameras, overheating nightmares demonstrate this just isn’t the case even on short shoots in high quality 4K 24p. The reliability issues are so serious that paid professional work is a complete gamble in 4K on both models. Even the EOS R6 with the lower 20 megapixel sensor at the lowest frame rate (4K 24p) suffers repeated shut downs on a short shoot. In my opinion, this is a problem for Canon so …

On a personal level my condolences go out to Mr Maeda-san. We don’t know the seriousness of his condition, but I hope he can bounce back and enjoy his retirement. When not at work, Masaya Maeda can be found building model airplanes and playing golf. He is also a fan of Eric Clapton. Masaya Maeda was …

Just when you thought the Canon EOS R5 overheating drama had been swept under the rug, the EOS R6 runs to pick up the baton. But this time, not everybody can agree on what it’s good for. These Canon articles write themselves really. If ever they could show you two products that justify my criticism of the company over the last 8 years on EOSHD, it is the EOS R5 and R6. There is no bias, like I say the articles simply write themselves time after time. Be it mushy 1080p on the 5D Mark III, huge crops in 4K
