Improved AF performance?
We're told new firmware for the EOS M will be coming “soon”. Possibly in the next two weeks. The firmware will address various things in the camera, the biggest being improving AF performance.
Do not expect miracles about how much it can be improved, but the camera should “hunt a lot less” in lower contrast situations. We'll also see an improvement in AF tracking.
