“But the emails...” = “But 30 fps at 50mp...” :-) (sorry, I couldn’t resist that joke given that Tony just kept coming back to the 30 fps argument in this “review”).
It is still too early make any informed judgement about the A1 and its performance. We need production copies with final firmware (even if the test units shipped with 1.0 fw). Plus RAWs cannot be processed in Lightroom yet. I know a lot of people are excited about this camera, and expectations are very high, but if we have learned something about gear so far it is that cameras are never as good as the manufacturer’s marketing department or sponsored spokesperson would like us to believe.
Video performance taken out of the equation, it seems like the Canon R5 (along with its RF glass) seems to be holding up rather well compared to the 40% more expensive Sony A1. More to follow.
