Here Is The First Commercial Canon EOS R5 Cooling Mod, Doubles 8K Times

It had to come sooner or later, now here it is. The first commercial Canon EOS R5 cooling modification.

Kolari Vision known for filters and camera mods, announced their Canon EOS R5 cooling mod. Kolari claims that their mod doubles 8K video recording times and cuts recovery time by 66% at normal environment temperatures. Sounds impressing. Have a look at the table below. Kolari claims that with an environment temperature of 15°C (59 Fahrenheit) you’ll no longer get a time limit when recording 8K. At 20°C (69 Fahrenheit) you get 44 minutes and 25 minutes after recovery. Not bad, eh? However, as PetaPixel underlines, the mod will likely void your warranty.

Says Kolari Vision:

When the R5 was released, we also learned that it overheats quickly in 8K shooting and in some 4K modes. Initially this was handled through a timer chip in the camera independent of actual temperature.  After public backlash, Canon quickly released a new firmware that patched the timer issue and started actually using the camera temperature data instead, but even with this upgrade the performance boost was minor, for example at 20C instead of overheating after around 19 minutes, the new firmware allowed you to shoot around 25 minutes, and the recovery after overheating.

In several thermal analyses of the camera, the processor on the motherboard seemed to generate most of the heat. In the stock design, Canon places two thermal pads partially over the processor and pumps the heat into a small heatsink. That heatsink however sits under another board and does not vent heat anywhere further.

To remedy this problem, we took an R5 apart and designed a new heatsink to vent the heat from the processor to the camera case where it could dissipate faster. We tested aluminum initially, but eventually settled on a thick copper heatsink to transfer heat more efficiently.

This design draws heat out of the processor and brings it around the motherboard and out to the rear case where it transfers heat through a high efficiency thermal pad. This design is fully internal to the camera and maintains the weather sealing of the camera.

We tested the modified camera at 8K-D IPB 30FPS at 59F (15C) and 69F (20C). At 15C, the R5 never overheated in our hands. At 20C, where the stock camera last around 25 minutes, after our mod the camera lasts 44 minutes, almost two times the initial shooting duration. What’s even more important, is that the camera recovered a lot faster after it did overheat, giving more shooting time after a short recovery. With the stock camera, we could only get about 8 minutes of additional shooting after a 5 minute recovery, where the mod was able to shoot 25 minutes after the same 5 minute recovery, a 3 times faster overheating recovery.

Kolari offers a modification service for your Canon EOS R5 at the price of $400. You can also buy an already modified EOS R5 at $4,440. Instructions for DIY aficionados will follow later this year.

More Canon EOS R5 review stuff is listed here (many reviews), for EOS R6 review stuff see here. The EOS R5 is highly regarded as a stills camera. In particular, the EOS R5 autofocus system seems to be huge leap forwards. The official Canon EOS R5 user guide and manual are available for download: EOS R5, and for the EOS R6 too.

TTArtisan 21mm F1.5 ASPH Review (not a lens for everyone, D. Abbott)

Ttartisan 21mm F1.5
View Post

Here is a review of an inexpensive and rather exotic lens for the RF mount, the TTArtisan 21mm F1.5 ASPH.

TTArtisan 21mm F1.5 ASPH at a glance ($239):

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.5 to f/16
  • 5 High-Refractive Index Elements
  • 1 Aspherical Element
  • Minimum Focus Distance: 27.6″
  • Manual Focus
  • 10 Blade Aperture

Dustin Abbott posted his exhaustive review of the TTArtisan 21mm F1.5 ASPH. We think “thoroughly” is the right way to describe Dustin Abbott’s review. And the TTArtisan 21mm review follows suit. From his conclusion:

Optically [the TTArtisan 21mm F1.5 ASPH] is a mixed bag. You can forget shooting infinity subjects before F2.8 if you care at all about image quality, and corners never quite get pin-sharp. The TTArtisan 21mm is also quite flare-prone and suffers from a lot of vignette. The minimum focus distance and resulting magnification is truly terrible. But it also gets nicely sharp when stopped down and delivers some really interesting colors.

Put simply, the TTArtisan 21mm is not a lens for everyone, but if you have just bought into a new mirrorless system and don’t have much left over for lenses, it can deliver really good results for the bargain price. Just learn how to use it within its strengths, and you can easily produce some stunning images on a budget.

As usual with Dustin’s reviews, this one too comes with a huge set of sample pictures, comparison charts, and all the information you might want to know. Dustin’s reviews are what I look for when I am about to purchase new gear. And for those who prefer to watch their reviews, here you are:

The 21mm f/1.5 Lens for Canon RF from TTArtisan is a classic manual focus wide-angle prime lens well suited to landscapes, room interiors, street photography, and more. It features a bright f/1.5 maximum aperture, allowing it to be used in low-light situations and providing finer creative control over depth-of-field. The combination of five high-refractive index elements and one aspherical element provide sharpness and realistic color transmission throughout the image area. The integrated lens hood reduces potential lens flare for optimal color saturation.

No, Sony Does Not Manufacture The Canon EOS R3 Sensor

Do you remember the story about Sony possibly making the Canon EOS R3 sensor?

All started after Canon UK slightly changed their wording on the EOS R3 presentation page. From “designed and manufactured by Canon“ to “developed by Canon“. An interview with a Canon Russia exec didn’t really shed any light on the question. Something might well have gone lost in translation. So what?

In the last days new doubts were disseminated. Someone referred to a Sony product sheet that describes a 30MP sensor, claiming it is the EOS R3 sensor. Apparently, the proof for the claim is nothing more than the rumored sensor resolution of the EOS R3. That’s 30MP, same as the Sony sensor. Very weak argumentation in our opinion.

To put an end to speculations, PetaPixel asked Canon about the rumor that Sony might manufacture the EOS R3 sensor. Canon answered:

The sensor in the upcoming EOS R3 camera is Canon designed and manufactured.

Will this put an end to the polemics? We think it will not. Throwing crap on Canon seems to be a must for certain people. Not surprisingly, the same characters that allege Sony makes the EOS R3 sensor have also started the EOS R5 overheating soap opera after the R5 launch.

Go out, stay safe, take photos.
