600D + AF assist beam = slower focus as 5D3

i face the same problem in 600D, while in older cameras such as 40D 450D and 350D the af works ULTRA FAST.

600d + ex 580 II assist beam = slower focus

Terrible lag on focus while the assist beam lits.
looks like the assist beam of the flash isn't that strong with 600D rather than 350D

My tests made in the same dark room with the same lens and same flash same conditions, same settings.

Also checked that myself. Come on guys, what are you waiting for? if you want to make better cameras, you'll have to start by improving support for older equipment!

Its really not about support for the older flashes...these cameras have the same problem with the new 600's

and whats the solution to this problem?

its a real problem when you are inside a church or a club where the light conditions are way too low and no i refuse to buy 5D 3 or 6D for better focusing, not when older cameras such as 350D and 40D are focusing instantly with a flash on.
