Just to be clear, the firmware update does include an improvement to the AF speed when using the Speedlite’s AF-assist beam. You can see the complete list of improvements and fixes in our product advisory by clicking here
Thank you Carerra911 for clarifying!

I have that issue with the 600 ex rt i rented. slight lag from the auto focus lock to the shutter release. but i havent had major issues with af while using a custom bracket. sometimes the flash and the camera arent aligned properly with eachother so i slightly shift the camera to align it with the af beam. i really wish canon would update their oc3 cord with a built in af beam like the nikons do. nikons imo have always outperformed canon in lowlight.

Just installed the 1.2.1 firmware update in my 5D3 and it does seem to focus more quickly in low light with the IR assist. I have a gig tomorrow and will be able to confirm after that.
I would REALLY like to know when this will be fixed on the 1DX. It's just as bad as the 5D3!

There is a pro wedding photographer at the POTN forums who is going to give the 5D3 a try this weekend. He has been shooting in AI Servo was a work around but prefers One Shot when Servo is not required. I'll update his findings as well.
