Please add my concern. I have a new 600EX and a 5D3 and the performance in low light is terrible with a 24-105 F4. I got much better performance from a flash with my first rebel many years ago.
On my older Canon flashes, you could see a pattern projected on the target when the flash fired its focus assist. Now you don't.

sold my 5d mark 3 ...in the interim...I got a 1ds mk3....works better with the beam...but still not as good as my 5d mark2...also
the write time to review on the 1ds is deplorably slow, but i love the viewfinder! Why couldn't they put this viewfinder on the
5d series? Well I guess Canon wants you to buy lots of bodies...because not one of them has everything you want.
Looking back at my brief 4 months with the 5d mark 3...it does have a lot going for it....more accurate AF in general...shooting at ridiculously hi iso with no noise...great lcd...fast processor...the only thing wrong was that stupid
problem with shooting in low light with the flash beam. If they fix this problem...I will be buying another one.

Thank you very much to everyone at Canon for this, there is no mention on the website that this firmware incorparates the assist beam fix?, but Im assuming it does, I will install it later, would like to hear what others have to say,
Just a big thanks to everyone at Canon for listening to the Forums and helping us make this camera even more perfect,
all the best
