I use a Think Tank Retrospective 10 sometimes if I want as minimal a profile as possible. If you remove the deciders it fits the C100 with top and side handles and a 24-105 on with hood reversed. There's no room for another lens but TT makes modular lens pouches that you can attach to the sides of the bags if you want to carry more. Note that this isn't a close it up tight lot of protection and cushioning solution, it's an ultra lightweight, quick access for walking around solution.
i travel without the top handle unless i actually need XLR. otherwise i use a top cheese plate with a small mic/wireless and a regular rig handle. fits in far more cases that way and is ready to go
Great bag. Just know that the camera with handle and a lens attached fits, but thats all. I have a rolling bag for lenses and small monitors and keep all camera stuff in the camera bag. Lots of pockets for goodies on all four sides.
I have the Tenba Roadie mentioned above. It fits the C100 with just about any lens and mic attached and has room for a couple more lenses and plenty of space for parts. It's great for being able to pull the camera out ready to shoot.
The bag is big, but somehow doesn't seem too bulky. If you take off the handle, you can use their top tray in the bag to fit just about everything you own. I did that for a flight and managed to get C100, 5D3, half dozen lenses including 70-200, batteries, chargers, flashes, loupe, mics, and I can't even remember what else. It weighed a ton, but it still fit in the overhead bin as a carry on.
It's large, but it's tall enough to fit a C100, handle and shotgun, and even a baseplate and mattebox and monitor. If you don't mind having a large shoulder bag, it works for pretty much any set-up.
