5D III has some issues with AF-Assist Beam under low light - Speedlite 600. You might want to double check.

It is still an amazing flash. I actually bought 4 and I use them for photoshoots. I started using them for the club months later  and  that was when I found out about the issue. One thing I have never tried was all points auto AF selection. I honestly don't trust that setting especially  when using  a 2.8 aperture  but next time I use it at a club I might try it.

Based upon this I change my earlier vote for the Canon 600EX and vote for the Yongnuo YN565-EX instead. It can provide focus assist in total darkness (went into a bedroom closed all doors and curtains at night and could take pics of anything in any corner of the room with almost instant AF on my 7D + 24-70).

The AF assist beam is absolutely crazy; will effectively light up a dark room. Just took this with my iPhone of the weird beam it throws out Kinda looks like Lips with heavy Pink Lipstick

That's the same AF assist beam thats on the Yongnuo YN568EX as well, and my 5DIII focuses very fast in the dark with that.  Canon 580EX II comparatively puts out AF assist beam that is much less obvious.

I have two Canon 600 flashes and the Canon ST-E3-RT.  Awesome set-up for me, but the ST-E3-RT lacks an AF assist beam, so in very low light (single 60w bulb in a bathroom for example) it gets dodgy, but outside as a fill in set-up it's fabulous, fast, works, and is very portable.

The ST-E3-RT is awesome. I love using it.

Agree with most here.  The 600ex-rt has given me sensational results and is very easy to use with the new LCD screen and menu system.

I vote for the Metz Mecablitz 58 AF-2 digital. Works very well, even the custom functions can be set in camera.

Basically it's a 580 clone, with a bit extra. It has a USB port for future firmware upgrades, and a small secondary flash at the front for fills, I like that very much. Oh, and you don't have to study the manual to get it working, the menu is very straight-forward

If you only have one flash, this also has the useful feature of a smaller secondary on the flash which can be used for front fill when you're bouncing the main unit.  I have the AF-1 (bought it 3 weeks before the AF-2 came out and 1 week before the related AF-1 prie drop, teach me not to hit the internet before a purchase).

Like it quite a bit, has all the functions of a 580EX, plus the above and some strobing capabilities.
