The head of Product and Consumer Expertise at Canon Russia was recently interviewed by PhotoWebExpo. To no one's surprise, he indicated the upcoming EOS R3 is not the top-of-the-line mirrorless camera, the future EOS R1 will have that title.
My readers know I am not a fan of the current crop of mirrorless cameras, notwithstanding the great improvement made in the EOS R5 and EOS R6 models. My biggest complaints are the latency in the EVF versus a top-of-the-line DSLR camera like the Canon EOS-1D X Mark III. The mediocre battery life even when a battery grip is added and the marginal benefit of the RF over the EF mount lenses.
The real question for me is does Canon intend the make the upcoming EOS R3 or the EOS R1 the sports and wildlife photographer's dream camera. I am not a videographer so all the 8K talk does not interest me. My current EOS-1D X Mark III camera is capable of taking 5.5K videos already.
My requirements for a full frame, mirrorless wildlife camera is rather simple. A mid resolution state of the art sensor with a burst rate of around 30 fps. Eye Control AF2 and Servo AF activation with a No latency EVF in an all weather, sealed EOS 1 like body and battery.
I should know by the end of 2021 whether there will be a full frame mirrorless camera in my equipment bag starting next year.
