Cannot import pictures with iPad Pro 2018 and Canon 5D Mark IV

There appear to be at least two issues here:

1. Using Apple's official USB-C -> SD Card adapter connected to my iPad Pro 11 (2018), and using an SD Card with photos shot on my Canon 5D Mark IV -- The iPad shows an "error" indicator (with no additional detail) when attempting to import a Dual Pixel RAW. Importing JPEGs and regular (non Dual Pixel) RAW files works fine.
2. Connecting the Canon 5D Mark IV directly to the iPad Pro 11 (21018) via USB (with a USB 3.0 Micro B -> USB-A cable and Apple's official USB-A -> USB-C adapter) -- does not work at all. The iPad launches the Photos app, but the import tab never comes up. When I do a similar setup with my iPhone (using the same USB cable and Apple's Lightning to USB Camera adapter) it works fine, including allowing me to transfer Dual Pixel RAW files.

Crazily, if I import the Dual Pixel RAW file onto my iPhone and let it sync with iCloud so that it appears on my iPad, everything works fine. I can view the file in Photos on my iPad, and also import it into Lightroom on the iPad. Once it syncs with the Lightroom cloud and ends up on my desktop, I can confirm that the file routed through the clouds is identical to the file on the SD card (SHAs match). So, it seems like the iPad supports Dual Pixel RAW files, it just doesn't support importing them. (And also doesn't support a direct USB connection to the camera.)

So... the workaround is:

1. Turn off Dual Pixel RAW. You can turn off Dual Pixel RAW in the menu: Menu > Camera Section > Section 1 > Dual Pixel RAW > Disable.
2. Use the SD Card adapter instead of a direct USB connection.

Or alternatively:

1. Import your Dual Pixel RAW photos using an iPhone, and route them through cloud(s) to get them on your iPad. Obviously, this may introduce huge workflow challenges depending on your internet speed.

If you'd like to read more about Dual Pixel RAW, and what you're potentially giving up if you turn it off, here's a good article: https://www.usa.canon.com/internet/portal/us/home/learn/education/topics/article/2018/june/whats-new-eos-5d-mark-iv-dual-pixel-raw-images/whats-new-eos-5d-mark-iv-dual-pixel-raw-image

The plot thickens!

I purchased this USB-C card reader from Amazon: https://smile.amazon.com/gp/product/B076MF378H

When I shoot dual pixel RAW to a CF card, I *am* able to import them onto the iPad using the above card reader. However, when I shoot dual pixel RAW to an SD card, I *cannot* import them using the above card reader. I get the same failure as reported with the official Apple USB-C -> SD Card reader. The images show up in the "Import" tab of photos, but I get an "error" exclamation point when trying to import.

So to summarize:

Importing to 2018 11-inch iPad:

• Plugging camera directly in through USB cable and official Apple USB-A -> USB-C adapter -- photo app opens but import tab never shows up
• Using Apple USB-C -> SD card -- cannot import Dual Pixel RAW, can import regular RAW
• Using above USB-C card reader and a CF card -- can import everything
• Using above USB-C card reader and an SD card -- cannot import Dual Pixel RAW, can import regular RAW

Importing to 2017 iPhone X

• Plugging camera directly in through USB cable and official Apple Lightning -> USB-A camera adapter -- everything works as expected (all files can be imported)

Also, I should mention that the physical build quality of the card reader I linked to above is hot garbage. I don't especially recommend the product, but a.) it *is* cheap and b.) it solved my problem, at least until it falls apart.

I just downloded latest arrival ios 12.3, and our problem is still there. Im getting f.....g borring to apple that more than half year is gone and they still dont fix this... this supposed to be Pro ipad but even ”normal” ipads are working well w both cameras :-(

I just finished call to Apple support.

Apple is aware of the problem and is working on it.

I hope they will fix it soon.

Yes, I was told they already fixed this issue and it will be released with the next version of iOS.

Any news on this issue?

My case went to apple ”pro” level support and they suggested to wait for future updates..... lets see when....

Canon said that its all up to apple to do it?
