From my experience with the R5, the R6 could literally be better than the A9 (marginally, aside for the $2000 price difference). The only thing that makes me think differently, is the sensor readout. Its slower than the R5 for some reason, even while sporting a lot of the same specs. I'd assume the lower line count would make it quicker than the R5, but there must be more to the calculation. While the slower readout is expected to be below that of the A9, I'm left wondering if anything else gets a similar performance drop off. Canon obviously cut corners to get the price down, but I still think it may be a match. But lets see if the specs hold up.
