"Canon seems to have understood that these EOS R and EOS RP were not really technologically advanced. As a result, they pull a development announcement from their hat that is fun to read. The EOS R5, which is expected to arrive later this year, will be the first "serious" package of the RF mount. The little that Canon has agreed to share is enough to make you salivate.
In the first row, there is the video, 8K! A world-first in the world of consumer cameras. An unprecedented ability that would allow Canon to recover the video crown, lost during the transition to 4K for the benefit of Panasonic and other Sony. Canon does not announce any frame rate, compression (codec), etc. You will have to wait for the launch announcement to get more information.
The other great news is the arrival of the mechanical stabilization of the sensor, a novelty for Canon. This lack of stabilization is partly responsible for the low ratings we have given to EOS R and EOS RP.
According to some information leaks, mechanical stabilization alone would save up to five stops. Together with the optical and electronic stabilizations included in certain lenses, this mechanical stabilization could allow you to gain up to eight stops.
Then, Canon announces an impressive burst of 20 frames per second in electronic shutter, as with the Sony A9, and a burst of 12 frames per second in mechanical shutter, such as Canon and Nikon sports cameras (1DX Mark II or D5).
we expect leading performance with tracking algorithms. Let us also hope that the buffer is generous so that the "sports" potential is not restricted.
Finally, the EOS R5 will have two memory card slots, which will change from the first limited models to a card, sometimes even in the battery compartment, such as the EOS RP."
