5D III and D800 tethering now supported

[figure1a]

Definitely check the cable/try a spare. I use these cables and they always work great and are good for getting long lengths:

With harddrives I found out that the front thunderbolt connector works flawless while the second one works not or looses connection easily.

so 6.4.4 is out, will it enable 5DIII tethering in OSX 10.8?

Funny  :)

Still waiting for Canon to update their SDK. Phase One can't do squat about it until then.

Canon makes two SDKs, one for themselves (primary) and one for third parties. They've updated their primary SDK with 10.8 compatibility, but their most recent update to the third party SDK still does not support 10.8.

I'd suggest contacting Canon to log your disappointment that they have not provided third party vendors an updated SDK.

Look halfway down this page though for the unofficial and not officially supported workaround:

When I do this the large preview in Capture One (6.4.2) won't snap into high resolution- it stays "fuzzy".

By "this" I mean "Make sure [camera > hot folder] is enabled and [camera > auto select new capture] is set and it will auto update.

Also, under capture one preferences you can disable canon tethering so that it won't give a connection error when EOS utility was running."

Hi Doug,

I'm not ready to migrate to C1 7 but would like to shoot tethered to C1 6 with my 5d MKIII.
Has Canon updated their SDK yet?  I'm using C1 6.4.2 and Apple OS 10.7.5.
