When I am traveling, I download from the 5DIV CF card to my iPad using the Canon supplied cord and a lighting - USB adaptor (I use the Apple one - I think around $35). There are two tricks: First, so far as I can tell, you need to import them into the Apple Photos app first. Second, I can't get the connection to work from the CF card in the 5DIV unless I remove the SD card (and no, it doesn't seem to matter how the 5DIV is set in terms of which card it is reading from). If I am importing from an SD card, I use an Apple SD card reader (again, I think around $35), for either the 5DIV SD card or SD from the M5. I have tried using a little card reader plugged into the lighting to USB adaptor but apparently the iPad doesn't have enough horsepower to power the adaptor. After the photos are in the Apple Photos app, I then import them into Lightroom Mobile so I can play with them while I travel. I too use the WD wireless pro and plug SD cards to be read directly. I find the software fairly funky, but it does work for extra security back up while traveling, without needing to go to the internet. That is, photos are then on the cards (kept until i'm home), iPad and WD. Of course, if there is internet and I have imported into Lightroom Mobile, they synch up to the Adobe cloud (I did pay the $5 per month blood money so I have enough storage on the Adobe Cloud). And, of course, internet with sufficient bandwith to synch to the cloud while traveling is fairly rare. I would like to be able to do three things that I currently cannot do (or can't figure out how to do): One, I would like to be able to import directly into Lightroom Mobile on the iPad without going through the Apple Photos app (which is a waste of time and storage space - the photos can be deleted from the Apple Photos app once in Lightroom Mobile but then Apple Photos wants to re-download them whenever you download from the same card. Two, I would like to be able to move photos directly from Lightroom Mobile to my desktop computer once home, without needing to synch them all to the cloud, then back to the desktop, then unsyncing them from the cloud. Third, I would love to be able to use Lightroom Mobile and the WD wireless drive to where the raw files and, I imagine, xmp files are stored on the WD and I can view and process them using Lightroom Mobile on the iPad. If anyone can tell me how to do any of those things, I would be eternally grateful. (I use Lightroom Classic CC on the desktop, and I recognize that Adobe has gone off in a different direction with Lightroom Mobile, so what I am asking for may not be possible. I will say I suspect that Adobe's direction is the wrong way but they are much smarter than I am and I'm probably wrong).
