Thanks for sharing. He fully and completely shot down all the arguments I had in favor of this new camera. I still have much of my Sony gear (loving the R5), and there are certain pieces of my Sony kit I won't be letting go anytime soon. One of them is the Sigma 24-70, featured in this video, which is possibly the best 24-70 I've ever used. I haven't shot it against the EF 24-70L 2.8, which I still own, but when I trim down, the Sigma is likely to stay with the EF on the chopping block. I also have no intention of purchasing the RF version. No need to duplicate or replace true excellence.
Sony still has an advantage in that their native lens selection at every price point is incomparable. Yes, Canon has put out some incredible high-end RF glass, but I can't buy great Sigma 14-24 f2.8, 24-70, f/2.8, and (soon) 70-200 f2.8 all for under $1500 each in RF mount. I didn't even mention primes like the 35mm 1.2 or the great Samyang 85mm 1.4 (okay, Canon RF has that one too).
