Tether shooting with the 1DX

    Very interesting. I had to test your observations, and you are correct.

    My 1DX behaves the same way tethered.

    Ethernet, which I use all the time to prevent handling the cards - besides being so much faster than USB - is likely locked into a proprietary Canon API. As you must launch the stupid EOS utility to activate the Ethernet port, it is not likely they allow anyone else to use the connection. But I could be wrong, and would be overjoyed if I am.

    Ethernet is an open standard, it seems lame to lock it down.

    And, oddly, the camera does NOT write to the internal card when tethered.

    I am wondering if others who tether (using ANY camera body) experience this as well? I rarely, if ever, use tethering but the technical side of this intrigues me.

    Capture one uses it's own tethering protocol which does not allow writing to the card. This is a well discussed limitation, but I doubt PhaseOne will ever resolve it. In fact they recommend tethering without a card in the camera.

    Also Capture One does not allow connecting to the camera's ethernet port via the internet protocol that canon uses.

    The work around I sometimes use is to tether via EOS utility and then use the hot folder function in C1 to browse and adjust the raw files.

    I'm curious to learn more about your experience tethering with the ethernet cable and how it is "so much faster than USB"

    I've done several tests with my 1DX on a few different computers and I determined (much to my disappointment) it was not any faster than the USB. I know the spec for ethernet is faster than USB 2.0 , but in practice my results do not show much difference.

    My basic test is to hold down the shutter for 2 minutes in burst mode, and see how many images transfer including the time needed to clear the buffer. RAW, ISO 100, no lens, body cap on, 1/250 sec shutter. Aprox. 150 frames is typical
    No other software is open or importing the images, just Eos Utility writing direct to the internal hard drive.

    I know there are several connection modes including FTP, wft server, etc. but I have only used the EOS Utility mode because it gives me full control the camera, plus it is the easiest to set up. It's not a great program, but it works.

    Can you tell me a bit more about your set up? Connection mode, computer system & OS. I'd love to find out that the ethernet is in fact much faster than the USB for tethering and I just need to adjust my settings.

    email me if you wish as this may be getting a bit off topic from C1. danielgoldwasser (at) yahoo (dot) com

    I'll email you.

    Our use cases are slightly different.

    We use the Canon/Nikon SDKs. This will give a high speed, capture controls and so on, but will by-pass any card.

    What do you mean? as far as I know Lr uses the Canon sdk to and I it safe the image on the card to!

    No it does not, it uses the camera as a mass storage device and CF card as a hot folder. Once image appear on card it is transfers to computer, this is the reason it is so much slower and you do not have options like live preview etc.
