OTG connector between camera and hard drive

[balarila]

When on a bird photography trip, I shoot thousands of digital photos with my DSLR. I back up photos on my portable WD hard drive connected to my laptop.

As a laptop is too heavy on a backpacking trip, I'm wondering if there is a small device that would allow me to connect my DSLR directly into my hard drive to download the photos into it. I recall some years back I saw a tiny OTG device with a little screen and some buttons that would let me do this but can't seem to find it now.

Any suggestions?

For one, the DSLR won't produce the power to power up the hard drive. You may be able to connect to it, but you'd have to plug the drive in somewhere.

Consider an Eye-Fi SD card and a small tablet. Once set up, the Eye-fi can WiFi directly into the tablet (or other device), as you take the pics. Makes just about any camera WiFi enabled.

I have a couple, and have run tens of thousands of pics through it.

My DSLR is a Canon EOS7D which uses Compact Flash so an SD card solution like Eye-Fi would not work.

Canon has the WFT-E5 wireless transmitter. Not sure if that can work in batch mode or each picture is transmitted as it is taken. I'd prefer batch transfer to a disk as I tend to travel light through hikes when doing bird photographies and would prefer a download to disk when back at basecamp.

Also, I have an ipad fopr a tablet. Not sure how easy I can connect a hard disk to that.

There are Compact Flash adapters for SD cards. No idea of how well they work, but they exist:

In any case, a DSLR doesn't push enough power to spin up a hard drive.

You could go with something specially made for that purpose, like these.

Eye-Fi is (painfully) slow for real-world. It takes half a minute to transfer a single JPEG, I wonder how long it will take to transfer a raw file.

I just timed mine.
.jpg was 4 secs, 15.1mb RAW was 18 secs.
From shutter click to done.

Your smart phone or tablet: 1. Use MicroSD with adapter; 2.NFC, if your camera have one.
