You sure one of your "adorable" flying teammates didnt hit your camera bag?
I've seen some big assholes who want to stuff their huge baggages in the top compartments AT ALL COSTS. Punching, moving, shoving the hell of the nearby bags.
I once seen an ahole hitting and scratching my heavily protected laptop. because his suitcase couldnt fit and he was too lazy to walk 2 rows back to get into another compartment. I had to call the moron as he was damaging other bags as well.

After that "experience".. I said NEVER AGAIN and now I store my very expensive equipments below the seat infront of me.

George,

I have no experience as of yet hooking either of my two iPads up to a video camera. But I have used my older iPad 2 to download images from SD cards and know I could, if desired, download stills from my Sony cameras via the mini-USB port.

The issue, I believe, is unlikely to be what brand of camera you're employing. Rather, it's what Apple has decided to provide us photographers with on the iPads. To my knowledge, Apple has provided ONLY two such means, each consisting of an adapter. So for my iPad 2, one end of each adapter has the 30-pin connector. On my iPad Air, it would be a lightning connector. In my case, the 30-pin version mates with the (backwards-labeled) Apple lightning-to-30-pin adapter, which then mates with the iPad Air, and yes, it actually works.

So what's on the other end of these two adapters? The one I use the most has an SD card slot. The other one has a USB 2.0 female port. I'd think you'd be obliged to use the latter if you're trying to record or display in real-time.

Apple has stated that these two adapters are EXCLUSIVELY for conveying digital files of photos and videos, and NOT any other file type! That's where my knowledge on this topic comes to an end.

Hope this helps.
