Versatil (Carry-On) backpack with insert system


Sep 30, 2017

I was wondering if anybody has a good input for me in terms of backpacks.
I'm looking for sth I can bring into an airplane (size) that can hold at least the following things:

6d+5d, 70-200 F2.8, 14mm f1.8, 15-30mm f2.8 and a 24-70 f2.8 as well as an extender, a 15" Laptop and alot of small stuff like batteries, power banks, astrotracker, motion control units for time lapse etc. Maybe a 24-105mm f4 will join the team in the future as well, who knows :/

(Given that I usually travel with timelapse rails and 2 tripods, there is anyway no way around to check in some stuff which is a bit less expensive or prone to break.)

Now comes the the tricky part: I often hike with a tent, a sleeping back and so on. I use a 75L backpack for that which can be loaded up to 25kg (55lbs), but is not constructed in any terms for photography. I would therefore prefer an airplane compatible photo-backpack that comes with a removable camera insert system, which I could put in my big and comfortable camping backpack. It would be great if the backpack would be "everyday compatible", for short trips or city days etc.

Does anybody has experience with something like that?
I'm currently aware of two systems:

Ideally the size would be around (or not exceed) 21.5"x13.5"x8" so that I wont run in trouble at the airport.
