Import 1D X files to iPad

[jrhoffman75]

Trying to import files from my Canon 1D X to my iPad using the USB3 Camera Connector. Works fine with my Canon T5i and a T6s. All I get when I connect my 1D X is grey squares; no images. Camera disk light flashes and if I select Delete Photos the files on the camera are erased.
Does anyone have luck importing 1DX files to iPad?
It worked last September before this round of updates.

If you shoot JPEG then iOS knows how to deal with them.  If you shoot RAW then the iOS devices recognizes it’s a RAW and can usually even view the embedded  JPEG thumbnail in the RAW ... but it can’t actually decode the RAW data.

When all I have is my iPad with me, I usually set the camera to shoot RAW+JPEG so I can at least see the JPEGs... and I’ll deal with the RAWs when I get back to a computer.

BTW, if you do shoot RAW only ... but want to see the JPEGs, the camera can process the RAW’s into JPEGs (after the fact) so you can still import the JPEGs.  I’ve done that once or twice because normally my camera is just in RAW mode (not RAW+JPEG ... but I needed JPEGs).

I worked with Apple. Did a complete restore. Still no luck. Same problem with iPhone.

If I plug in a USB card reader into the Apple dongle then the files come in OK. 

It it must be some strange interaction between the 1D X USB signal and the Apple system. 

It it works fine as direct camera download with the T5i and T6s. 

Same behavior with JPEGs. 

Reinstalled latest firmware. No change.

Did you try using a USB 2 cable? USB 3 is supposed to be downwards compatible with USB 2, and a USB 3 connector at the camera end is a subset of a USB 2 connector and will fit in the USB 3 socket. Maybe the camera and the computer have a slightly different understanding of the USB 3 protocol. The fact that the computer works with your two Rebels (which may not have USB 3) suggests something of the sort.

1D X is USB2. Same connector as the Rebels. It used to work. Very confusing. Off to Canon tomorrow.

Oh, OK. Your original post said USB 3.

The Apple device is called a USB3 Camera Connection. It can upload at USB3 speeds to certain iPads. It has a USB A female connection; it will accept USB2 or USB3 cables.

So in effect it's a USB hub? If so, I don't believe you're the first person in the forum to report a problem communicating with a camera via a USB hub.

[jrhoffman75]

Not a hub. It’s an adapter that plugs into an iPad and allows a standard USB cable to be connected. It’s is designed specifically for camera connection or USB card reader connection.

Ok, so it CAN read the files if they are imported using the card-reader adapter... it only has issues if using the USB adapter?

That is strange.  I find it particularly strange that it can't even handle JPEG images.  You should probably contact Apple.

(The one extra test I would do to isolate this issue is to make sure the camera isn't having general problems with it's USB port. In other words, verify that if you connect the camera to a computer (not the iPad) that everything still works fine.)

The thing about the USB adapter is that Apple says this thing was purpose-built for connecting digital cameras and is not meant to be a generic USB port.   

I'm wondering if the T5i and T6s are limited to just USB 2 ... and if the 1D X is trying to do USB 3 speeds... and the iPad isn't dealing with the USB 3 speeds as well.
