Here is a Canon EOS R5 vs Canon EOS R6 review for astrophotographers. High ISO performance is also reviewed.

Brent Hall takes the EOS R5 and EOS R6 out to photograph the milky way and to see how they performa at high ISO settings.

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.

Friday Hacker Blogging: digiKam 7.1 Released, Fully Supports Canon CR3 Format

Digikam 7.1

The open source and free software digiKam 7.1 has been released. Full support for the Canon CR3 format has been added.

Release notes for digiKam 7.1 are here.

When you buy an expensive camera, such as the latest Canon devices, you should expect the image provided to be seriously pre-processed by the camera firmware and ready to use immediately. This is true for JPEG, but not RAW files, where the format changes for every new camera released, as it depends on the camera’s sensor data. This is also the case for the Canon CR3: the RAW format produced by this camera has required intensive reverse-engineering that the digiKam team cannot always support well. This is why we use the powerful Libraw library to post-process the RAW files on the computer. This library includes complex algorithms to support all kinds of different RAW file formats, including the Canon CR3.

You can download digiKam 7.1 for 64-bit or 32-bit systems from their website.

As usual you can use this post to discuss about whatever you want.

Finally! Canon Answers EOS R5/R6 Overheating Questions In Interview

Canon Eos R5 Overheating

It was just a matter of time before some Canon executive would speak out about the Canon EOS R5 and EOS R6 overheating drama.

It’s Johnnie Behiri of CineD to interview Mr. Katsuyuki Nagai, Product Management Director of Image Communication Business at Canon Europe. Here are some excerpts from the interview.

Johnnie – CineD: The Canon EOS R5 is already shipping and there is no doubt that the camera is a technical marvel. What led Canon to introduce this product and don’t you think that introducing such an 8K mirrorless camera is a bit too early?

Katsuyuki Nagai-sanCanon: Someone has to be first, right?

[…]

Johnnie – CineD: Both cameras suffered from overheating issues in video recording and more than that, long recovery times. By introducing the latest firmware update, it seems as if Canon is trying to overcome some of those issues by allowing longer recording and shorter recovery waiting times (until the camera can film again). What exactly is causing those cameras to overheat and what’s the new FW doing in order to help here?

Katsuyuki Nagai-sanCanon: I think we should look at the fundamentals of the whole topic to give a better perspective. The cameras feature cutting edge features squeezed into compact bodies designed to offer weather resistance.

This is where we come to the first of the two governing factors that affect the cameras when it comes to overheating. Holding a very warm object for an extended period has the potential to result in what is known as low temperature burns. Secondary is to protect the internal components of the camera from the overheating. We limit how hot the external body of the camera can get to protect users, which is one of the causes of overheat shutdown. Some heat management must also be applied to ensure the camera continues to operate.

The interview is absolutely worth your time and we recommend you head over to CineD to read it.

Canon Released Another Firmware Update For EOS R5 and EOS R6

Canon EOS R5 Firmware Update Sony A7s Iii

A few weeks after the firmware update for the EOS R5, Canon released new firmware updates for the EOS R5 and EOS R6.

This time the firmware update appears to be more for the Canon EOS R6 than for the EOS R5, since it tackles with heat production on the R6. The R5 already had a firmware update coping with this.

Canon EOS R6 firmware 1.1.1 (download) incorporates the following fixes and enhancements:

  1. A messaging is displayed when [HDMI display: Camera+External monitor] and [Overheat control: on] settings are both enabled.
  2. When the RF100-500mm F4.5-7.1 L IS USM is attached, an image stabilization effect of approximately six stops* is achieved through collaborative control with the in-lens image stabilization.
    *Focal length 500mm, Based on CIPA(Camera & Imaging Products Association) standards.
  3. Fixes a phenomenon in which the IS capabilities may be degraded when performing continuous shooting in cases where the RF100-500mm F4.5-7.1 L IS USM lens is attached to the EOS R6 running firmware version 1.1.0.
  4. When using certain RF lenses for movie shooting, the in-lens image stabilization mechanism has been improved.
  5. Fixes a phenomenon in which the “Slow Synchro” setting screen is not accurately displayed, when the language is set to English.
  6. Fixes a typo displayed on the communication setting screen, when the language is set to Korean.
  7. Connectivity during FTP transmission has been improved.
  8. 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.
  9. 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 EOS R5 firmware 1.1.1 (download) incorporates the following fix and enhancement:

  1. When the RF100-500mm F4.5-7.1 L IS USM lens is attached, an image stabilization effect of approximately six stops* is achieved through collaborative control with the in-lens image stabilization.
    *Focal length 500mm, Based on CIPA(Camera & Imaging Products Association) standards.
  2. Fixes a phenomenon in which the IS capabilities may be degraded when performing continuous shooting in cases where the RF100-500mm F4.5-7.1 L IS USM lens is attached to the EOS R5 running firmware version 1.1.0.
