A new firmware version for the Canon EOS R5 and EOS R6 has been released: version 1.2.0. Especially the viewfinder behaviour in continuous shooting mode with mechanical shutter has been changed.
Note: in the meantime another new firmware version (V 1.3) is available, which contains significant improvements again.
New viewfinder behavior
In the phase in which the mechanical shutter of a mirrorless digital camera is closed and the captured image is stored, the sensor obviously cannot provide a live image.
Previously, the Canon EOS R5 and R6 displayed the last image captured during this phase in the High speed continuous shooting and Low speed continuous shooting modes. Although this avoided the dark phases between the images, as is usual with SLR models due to the flipped up mirror, the display always lagged behind reality, which often made it difficult to follow a moving object.
In this update, Canon has fundamentally changed this behavior.
Instead of displaying the last image as a continuous image, the viewfinder image is simply switched off when the shutter is closed. It then appears black at this stage. All images that can now be seen in the viewfinder are therefore live images without any significant time delay. You feel as if you have returned to the era of SLR cameras.
The image flickers now, but I actually have the impression, that the tracking of moving subjects is much easier now. You can change this behavior in the High speed continuous shooting mode by activating the High speed display in the SHOOT7 menu. However, I have discovered for myself that I can now get along better by switching off the Hight speed display, which I had previously always activated.
Nothing has changed in the new firmware for the electronic shutter. Unfortunately, the R5 and R6 in this mode can still only shoot either continuous firing at 20 frames/second or single frames. With the high continuous shooting speed, the viewfinder does not show any significant lag, making subject tracking easy.
In addition, to adjust the viewfinder brightness (Menu SET UP3 / Viewfinder Brightness), there is now finally the option Auto, which controls the display brightness depending on the ambient light. Often the viewfinder image was too dark on sunny days - but, due to the actual lack of sunny days 😉 , I can’t test, whether this setting controls the brightness sufficiently.
Anyway, this is a welcome update, but unfortunately this option is not available for the back screen.
In addition, cooperation with the new EL-1 flash has been improved, the compatibility of HEIF files has been increased, and autofocus and shutter release during zooming is now supported on some RF and EF lenses.
The latest firmware can be downloaded here at Canon:
The resulting ZIP file must be unpacked and the enclosed FIR file copied into the root directory of a memory card. The actual update process can then be started in the menu SET UP5 / Firmware. The battery of the camera should be fully charged or the camera should be operated with the external power supply. Be patient, this will take a while:
For the new firmware, the Canon applications must also be updated, currently the following versions are available:
・Digital Photo Professional 4.13.10
・EOS Utility 3.13.10
・Camera Connect 2.7.20
・Digital Photo Professional Express 1.4.0
The current versions can be downloaded here at Canon.
