Gordon Laing explains the updates in firmware v1.1.0 for the Canon EOS R5

Canon has released a firmware update for the Canon EOS R5, this version will be 1.1.0.

Firmware Version 1.1.0 incorporates the following fixes and enhancements:

  1. Useful messaging is now displayed when [HDMI display: Camera+External monitor] and [Overheat control: on] settings are enabled.
  2. When using certain RF lenses for movie shooting, the in-lens image stabilization mechanism has been improved.Fixes a phenomenon in which the “Slow Synchro” setting screen is not accurately displayed, when the language is set to English.
  3. Fixes a typo displayed on the communication setting screen, when the language is set to Korean.
  4. Connectivity during FTP transmission has been improved.
  5. Fixes a phenomenon, in which the card access time may take longer, when using certain CFexpress cards.
  6. Temperature detection and shooting time control in video shooting have been improved. In addition, the total shooting time when the short-time recording and power-on/off are performed repeatedly at room temperature is improved.
  7. The phenomenon in which the movie recording time available is not correctly displayed when the Date/Time/Zone is not set has been corrected.

Canon also announced that firmware update will be coming in early September that addresses the RF 100-500mm f/4.5-7.1L IS USM.

The firmware scheduled for release in early September will incorporate the following improvements for the RF 100-500mm f/4.5-7.1L IS USM.

  • Supports 6-stop image stabilization. (CIPA-compliant)
  • Improves IS capabilities when performing continuous shooting under specific conditions.

Gordon Laing explains what he found using the firmware in regards to temperature control.

The update that’s most interesting is the change in temperature detection. The camera will now check the three sensors more often, to give a more accurate real-time reading. There is some hope that there will be reduced cooldown times and longer record times because of this. However, Canon has not changed the temperature in which the camera will give you an overheating warning.

The 29:59 limit on record time has not been changed. Longer recording periods didn’t see a significant improvement in record times or recovery times. Though there was some improvement.

However, in 4K120P, the Canon EOS R5 allows for 7 minutes and 30 seconds of record time. The new firmware does not increase that time. However, when shooting short bursts. With the original firmware, Gordon was able to record 22 30 second clips with 30 seconds of recovery time between each clip before the camera overheated. With the new firmware, that number increased to 96.

What is interesting, is that Gordon tested taking short clips at 4K120

That is enough improvement that I can't see heating ever getting in my way. An aside to those who would whine about having to shut the camera off - if it isn't cooling as fast turned on, it is also eating your battery, so turning it off makes sense on at least 2 counts.

Out of all the reviewers, Gordon is one of the only ones worth anything. Constructive, intelligent, and not a sensationalist. Adult enough to be nuanced and careful even when criticism is warranted, and able to realize when it is not.

His conclusions make a ton of physical sense. The amount of capability in this camera generates real, problematic heat, just like any decent test shows where people aren't forcing it or disabling safeties. Canon is using 3 sensors to protect internal components for long life of the components, just like any other modern high speed circuit that throttles or shuts down (hard drives, CPU, tons of things have thermal limits). Overheating ASIC and sensors repeatedly can and will degrade them.

Very sensible that ambient temperature is measured in order to predict record time as a function of starting temp plus expected temp rise over time in that mode. That isn't actually a bad way to do it if you want to keep a conservative safe limit for the dies of the chips and sensor. Sure, if the product didn't have the huge sensor and processor activity and strong IBIS and weather sealing, it would cool better and run longer or indefinitely, but we are back to square one where any intelligent testing shows real thermal issues and the product does what Canon says without any conspiracy. People can hack all they want or complain that Canon should sample the temperature constantly and raise the limit, but without the whole engineering picture it is irresponsible to say we know better.

In my own thermal tests in hot sun, the camera was quite predictable and did overheat, and disabling IBIS and the EVF made things cool much faster and last longer. It makes perfect sense to me that even idle, just running the processor and EVF and IBIS, produces enough heat inside the sealed body that must flow away from the sensitive components where temp sensors will be placed. So no conspiracy after all, just a sub optimal algorithm that has now been improved. Can it be improved more without compromising safety and long term reliability of the camera? Can lighter codecs help? How many people actually need this and cannot just use an external recorder vs all the whining and negativity?

Sadly the comments on Gordon's video are the same confirmation bias trash we knew they would be be already: proof of the cripple hammer, fake timer, blah blah blah. I'd say these people are all paid shills for another brand, but the truth is sadder than that- average video crowd is just that dense and spoiled.

Update went well although it was stuck on 0% for what seemed minutes :) In hindsight I did the upgrade with a rather empty battery so that's a thing to check. Anyway, I did some shots, made some movies. All is well but I did not check heating issues yet.

I was stuck at 0% for a while, too...and the whole time I was thinking "I SHOULD'VE SWITCHED TO P MODE LIKE THE INSTRUCTIONS STATED!!". (I have pretty much every mode except for M and Av disabled, so I was too lazy to go in and enable P) :LOL:

Well this is embarrassing.....

I took a sledgehammer to my brand new R5 after Chelsea Northrup's husband and full-time viagra salesman told me that the 4K was unusable.
But now Gordon says that, providing I carry around a small British refrigerator, that I should be able to shoot the biopic that I have been planning, at 120 fps, called "Andrew slays the Giant. The story of one man, armed with only a giant chip on his shoulder, defeating the nemesis of all aspiring Hollywood DoPs".

Lights, camera.... oh wait..... what's that flashing red symbol mean?
