GST, how easy/difficult is it to grab the camera from that bag when it's on your back?
There is only one problem that I have encountered with pulling the camera out, and that is the bag being to high to be able to pull the camera out easily.
If you loosen the belt so that when you twist the bag to your front with easier access to the camera, the bag is loose on your back while walking. It is difficult to find a compromise between the two. I don't really know how to explain it, so tonight I will take a video of me accessing the camera to give you a better idea of what I mean.
Hopefully that makes sense.
P.S. - I will make the video without my shirt tonight
