Kai made a comparison between the two cameras. I do not believe they are direct competitors as they serve different purposes. Still if you wanna hear what he has to say check out his reviews:
The Canon R1 will compete with the Sony A1, but especially with the forthcoming Sony A1II, which will probably be announced at the same time as the R1 (late 2024 or early 2025).
So far we only saw “product” images of the R1. So here are some images of the “real world” R1 courtesy of Federico Basile:
Still no info about the specs of the cameras and my feeling is that the rumored specs are sooo wrong :)
If you own a Sony cameras and these then it’s a no-brainer as it only cost me about £30 from the DJI store. You need to update the firmware of the Mic 2 for this work. I’ve put the compatibility list in the comments. It worked on the FX6, FX3, a7siii, a1 and a7iv. Whilst the RØDE Wireless Pro are a better set as they come with lav mics and have timecode, these are still great and are now the best budget dual wireless microphone system for for the Sony miShoe now. I’ve only come across one other that isn’t by Sony which is from Godox, but they aren’t in the same league. Don’t forget the DJI Mic 2 transmitters also record internally in 32 bit float.
The a9 III is an undeniably ground-breaking camera….sets a new standard for what we can expect from a pro sports camera, and Sony appears to be adding the workflow features that the most demanding pros are requesting. There are some trade-offs being made to deliver the a9 III’s super-fast capabilities but taken as a whole they allow it to pull ahead of the field.
