It's in the bag?

The problem with pro-body cameras like the Nikon F5 in the picture above, with their built-in vertical grips is the paucity of carry options for them. There are minimalist "DSLR holsters", which are padded affairs carried on a belt that hold pretty much the camera and a lens up to about 70-200mm f/2.8 size, and nothing else. And then there are various full-size bags that are intended to hold a couple of bodies, several lenses, flashes, a tripod, and a partridge in a pear tree.

Big cameras are used by serious photographers for serious photographer business, apparently.

But I like to play with obsolescent pro cameras, and if I'm out walkabout in the city, I just want to bring the camera along and an iPad, maybe a notepad and some pens.

I have a Think Tank Suburban Disguise 30i, which is a pretty minimalist bag. It has an iPad compartment and it'll hold even a decent-sized DSLR like the D700 or 5D Mark II, but it's just not quite deep enough for a pro body (or a battery grip on a regular camera.)

My ideal would be a bag with interior dimensions about 11" tall by 8" square, with a lid that flipped open and a slit pocket on the back to hold a normal-size tablet in a vertical orientation. Like this, but a little deeper and taller.

Alas, I am still looking.
