Not sure how the wireless transmitter can send faster than the physical gigabit port. See my last post on SportsShooter:

Because it works and it is designed for the purpose. I believe that it will support simultaneous shooting with smart buffer while it transfers files, which, I believe, was one of your wishes.

---------------------------

For those following along, it appears that Jim has gotten (as of 5:11 PM, Oct 16, 2012) the direct connection of camera to computer through Gigabit-Ethernet (GigE) using a null-ethernet cable, and by turning off the firewall on his computer. WTG Jim.

"Cam:
IP - 10.0.0.1
Gateway 10.0.0.2

Laptop (PC)
IP - 10.0.0.2
Gateway 10.0.0.1"

---------------------------

Now the problem appears to be sluggish transfer speeds from card to computer, indicating that there is a bottleneck. From Jim's post on SportsShooter:

"Well, this comes from CPS....

According to CPS, the White Paper for the 5DII (he couldn't find anything on the 1Dx) had a max read rate of 135Mb/Sec or 16.875 MB/sec.

So assuming the read rates have increased, the bottleneck is the reading from the card, NOT the ethernet port.

I took the same card and read it to my computer 2 different ways, one via FTP, the other via a Lexar Pro Dual Reader. Here are the results:


Lexar Professional 1000x 32GB Card.

Windows reports 29.7GB Used (31,944,507,392 to be exact)

Using a Lexar Professional Dual Slot (CF/SD) USB 3 Reader to a set of striped SSD Drives:

Using Robocopy Command: robocopy f: . /s

Speed : 94068683 Bytes/sec.
Speed : 5382.653 MegaBytes/min.

That's 89.7MB/Sec, taking 5:39 seconds to copy all files on the card.

Using FTP Transfer over a GigE connection:

26:03 to transfer the same files...

Which equates to approximately 1.2GB/Minute or 20MB/Sec over FTP which means it's the reading from the camera of the card and pushing that data to the GigE. Which really sucks if that's the case. He said there was a white paper on the 5DII he was getting his info from about reading from the card, not sure if one exists yet for the 1Dx.. but basically the bottleneck is card reading..."

-------------------------------------

Does that sum up the current situation, Jim?

yup. It works. Just not how I want it to. LOL. Wish the GigE built in worked like the smart buffer of the WiFi. Disappointing to say the least..

I'm going to rent the wireless transmitter for a few days to see how it works... and then go bitch CPS out of it works like the GigE Should work.. LOL

Well, IMHO, they should both work the same way. Otherwise, why even put a damn GigE port on the camera if you can't transfer at full speeds when shooting. Just stick to making everyone buy a $600 wireless receiver then. Sometimes I just don't get the "engineering" reasons for doing things like that. They could has saved themselves an extra $10 a camera and just put a USB3 port on it and called it a day.

Shot tethered via Gigabit ethernet tonight. Seems like that shooting tethered works just like shooting with the wireless. You aren't waiting for images to download like you do when shooting via the USB and EOSUTIL.

Only pain in the ass is that you have to wait for all images to transfer before you can use voice annotation on an image.. Which aren't transferred so I'm not sure why this restriction exists and if it's the same with the wireless (guessing yes) transmitter.

Was nice to walk into the press box, open my laptop and not have to wait for anything to download. Second half of the game I set PhotoMechanic to LiveIngest and had my pics partially captioned and slugged for publication.

Mostly good news.

Does it make sense to use a separate sound recording utility with your laptop, or a separate voice recorder altogether, to record the voice notes?

Nah. If I want an annotation I can download them after, the files are tiny, so it would take a matter of seconds. Or, if I really need the info I can go back and listen on camera. I'm still going to talk to Canon about this part to see if there is a way for it to force the voice annotation over.

And.. That's one of the reasons I bought the 1D series.. Using another means of recording, writing, etc.. is well.. painful!
