Seemed to me like a long term Canon user who had been waiting awhile for an improvement on what he had been using, and now that he is mainly doing Landscapes, as he said in the video, he has been looking for something new. And after using the EOS R, and finding little impelling reason for him to buy, as he felt it no improvement over the 5DIV he already uses has prompted him to look at other options. So he said he would be trying other options over the next few months. He didn't even mention the D850 he was using in his latest video, (though he did highlight he was using Nikon at the start of the video) which I think someone going after clicks would be doing with every camera they would be trying. I like his videos, he seems a good chap, so I take his actions and motives as genuine. If he ends up changing I think it may be between the Fuji GFX 50R/S, Nikon D850 or the Sony a7RIII. He may hold on with Canon a bit longer in the hope of the hi res and overall sensor improvement, time will tell.
