I'm new to the world of flashes and transmitters and was thinking about grabbing the 600EX for the 5D Mark III, but mainly for the AF assist light. So I wanted to ask, do 3rd parties ever produce alternate AF assist lights? I've seen a few knock-offs of the ST-E2, but couldn't tell if they had AF assist or not.

I'm assuming the Canon ST-E2 itself is not an option as the 61-point AF is bound to have points at different places from the pattern in that unit.

It's been suggested that creating a matrix of NIR LEDs will do the trick, is this comparable to a patterned beam made for the camera's AF?

Thanks!
I'm also a novice at flash but I have a few to play with.  The 600EX-RT is probably the way to go.

The Yongnuo ST-E2 is cheep and usefull on 2011 cameras.
On my 5D3 it fires prior to 1st curtain. Useless. Also it's AF assist is weak compared to the Canon flashes.
I've just tried focus into a dark room with various attachments.  5D3 w/- 24-105@105
1. 600EX shows a dense wide grid of deeep red light with reasonably quick focus.  Reliable.
2. 580EXII very similar.
3. 430EX similar but weaker and slower.
4. Yongnuo has a week patern of vertical lines. I achieved focus with difficulty.

Go with the 600. Even though it is a big lump on your camera just to get a bit of light out there.
Or maybe a laser pointer or torch.

if all you want is AF assist these bad boys do it nice and cheap

they through out a grid beam, works pretty well, tons lighter than actually having a flash on the camera especially if you dont want to actually set the flash off, and more compact too
I have one of these. Appears not to be compatible with 5D3.

It doesn't work with the 5d3 or are did you hear that it doesn't?  I have a 5d3 and was about to buy one of these since it doesn't have a triggering system like the 7d.  If you know for sure that it doesn't, that would save me $100.

I have one. Works well with my old 500D.  With the 5D3 the flash fires but the results were way underexposed.
I assumed it was operator error as I'm still finding my way round the 5D3. Googled. All I found was this discouraging
thread at dpreview.

I would love to be wrong. I would love it to work.

Someone else try this?

I have an old Epson P-5000, a precursor to the Color Space.

Rather than buying a new similar device, I'm seriously thinking of buying the Apple Photo Adapter kit for iPad and a Seagate Go-Flex Satellite.

This way one can download photos to the iPad, view them and store the keepers on the Seagate.
Not as quick and direct as the handheld devices, but arguably a better screen for viewing the pictures.

Anyone tried this combination?

I have this combo.  All good except that the seagate satellite is WiFi output only.  Means that you have to
plug into a USB port and load it up from a computer.  Also the satellite is NTFS so I had to install a kernel
module for it to work on my MBP.  Software comes with it. 
It will store RAW (or anything) of course but its software only displays jpeg on the go-flex iPad app.

There is a Linux hack to make it work as you would like.  However, the install is diabolical. 

So in short, you still need a laptop with you. Excellent for loading up with HBO video for the trip.

For my attempted fill flash I had centre point AF, evaluative metering and front curtain sync.  The face fairly
much filled the frame and was blown out horribly. Six shots all the same.
Is this where I should be using HSS?  Setting manual and letting the ETTL do the work? I'm sure there is something
I'm not getting about fill flash.

I too have very mixed flash results with my 5D3.

First try was using a Yongnuo ST-E2 on the 5D3 and a 580EXII in my hand for fill flash.  The flash fired but
the exposure is way, way underexposed.  This was in sunlight, spot metering, ETTL, Av, auto ISO. 
A thread on dpreview indicates that others have had similar results.  The Yongnuo ST-E2 is fine on my 500D.

Second try.  Next day I dropped AU$800 on a 600EX-RT and tried some more fill flash in sunlight. This time
I used the 600 on a hot shoe cable.  Faces not in full sun exposed well, however, faces in full sun were
blown right out.  3 or 4 stops at a guess.
I'll put this down to me not knowing what the hell I'm doing.

Third try, inside in soft light with the 600EX on a wire bouncing some fill.  The 580EXII was group B as a key
with a beauty dish in close and I had a 430EX group C as a rim flash.
I got consistent pleasing results.  Maybe I'm getting a clue or maybe the camera in Av is just good at this.

So I wonder why the sunlight fill flash results were so over exposed.
