This is very useful when on a trip and wanting to send pics and videos to someone on the Internet.
I like to send selected pics when I locate a free Wi-Fi access (hotel, coffee shop,etc). Can't do this from my camera.
I can now, with the OTG device, move items from my camera's sdcard to my phone. Then I can send via the internet. This also allows me to free up space on the Camera's sdcard for more pictures ... if i have space on the phone internal storage or addn micro sdcard (not available on iPhones).
I expect future DSLR cameras to be Wi-Fi enabled. But until then...
Did you know there are 512gb sdcards now?
I haven't tested them in a camera or phone (or OTG device) yet but they will be useful storage devices for times when you are taking a lot of pics or have large data files to transport.
More on this, as I acquire and test these large and cheap sdcards and micro cards.
