You can tell a lot by the way your camera shoulder harness feels. It’s meant to be comfortable, believe it or not. If it’s not comfortable, that means there’s something definitely wrong. So you need to ask yourself how it does feel when you’ve got your strapping system on. Don’t just go on auto pilot and don’t just block out how you’re feeling. Recognize it, because that way is the only way you can make things better.
So, is your camera neck strap too tight? If it feels really snug, you have power over that. There are adjustable straps on either side of the camera shoulder harness. You can loosen them and make them feel much better if that is what you would like. No one likes to feel like they are getting pinched or squeezed to death.
On the other hand, if it feels like your camera is bouncing around a bit too much, there may be a little too much slack in your straps. Be sure to tighten them to the point where you can fit two fingers in between your body and the strap. This way, you will not feel the bouncing as much and it also will not be too tight for you. That is exactly how your camera shoulder harness should indeed feel.
