On our last road trip we lost our laptop and miraculously got it back.
Next time, I don't want to take the laptop, instead I'd like to download photographs from the Canon camera directly to my cellphone for 3 reasons:
1) It's a backup in case something happens to the SD card in the camera
2) It's easy to share photos online from a cellphone
3) It saves space not having to carry a laptop!
Most of the folks I met (including the store where I got the cables from) said it was impossible to connect the Canon to an Android device via USB without additional software and hardware, so I said let me try.
Here's how I connected the Canon 60D DSLR directly to the Sony Xperia X Performance via USB with just two cables.
All you need is an OTG cable like the one below in my hand, and the USB cable to connect your camera to a computer (although in this case you don't need a computer)
Plug one end of the (camera/computer) cable into the camera, and the other into the OTG
Turn the camera on, and then plug in the micro USB end into the cellphone
You'll see a popup on the phone like shown below letting you know that the USB is connected
Select the downloads application to do the transfer
The cellphone is now connected to the Canon camera
From your cellphone, select the photos you want to move from the camera to your cellphone
Select the folder on your cellphone to where you want to move the photos to
DCIM > 100 ANDRO is where the cellphone camera stores pictures by default, so I've selected that same folder
And select Move
The photos are now on your cellphone, with the originals still on the Canon camera.
