It looks to do what it should
The new firmware for the Canon EOS M will be coming soon, and there’s now a video out there comparing the performance differences between 1.0.6 and 2.0.2 (which may not be the final version).
I like the EOS M a lot, especially with the EF-M 22mm f/2 STM, however the AF performance of the camera has really given it a bad name. While I don’t think it’s any worse than a G15 in real world use, that’s definitely not good enough for a DSLR replacement/companion camera.
Below are a couple of videos showing off the performance
First with firmware 1.0.6 (current)
Now with firmware 2.0.2
As you can see, the performance improvement is obvious in this one test.
