The fit is tailored to the FZ1000 and quite "tight" fit.
The camera fits just so pure in his pocket, and it takes a few seconds before you stow the camera.
Recesses are at the edge of the shoulder strap of the camera, the camera fits well with attached strap in the pocket.
To have to take the camera completely out of his pocket to take pictures. One then has the loose bag in hand, because the shoulder strap so belongs to the camera. If you have no way the camera bag to store for this situation is the attached carabiner a good thing, you can attach the camera strap so the bag or "park" for example on a belt loop.
As noted by another user, the bag is a whole designed more for transportation.
Constant packing and unpacking for a photo tour is really a bit cumbersome.
