Highland photography is mostly walking. The shot at the end of it might take ninety seconds, but getting there is eight miles of peat hag, tussock and bog, usually in the dark at one end of the day. And if you shoot wildlife rather than landscape, you are doing that walk with a long lens and a body on your shoulder, which together can run to four kilos before you add a tripod.
What the Stalkers Worked Out First
There is nothing new about carrying awkward weight across this ground. Deer stalkers have been doing it on the same hills for two centuries, with a rifle of roughly the same mass and length as a 500mm lens, and they settled on their answer a long time ago: a wide leather sling, carried muzzle down, with the load sitting on the meat of the shoulder rather than hanging off the neck. Watch a stalker cover ground and you will notice the rifle barely moves.

Why the Strap in the Box Fails
The strap that ships with a camera is designed to be cheap and to fold flat in a box. It is narrow, it is thin nylon, and under real weight it turns into a cutting edge across the trapezius. Worse, it lets the lens swing. Every step transfers into a pendulum, which is exhausting over distance and genuinely dangerous when you are picking a line down a wet slope and something heavy is trying to steer you.
Width is what fixes this. A sling two inches across spreads the same load over enough surface that it stops digging in, and good leather conforms to the shoulder rather than sliding off waxed cotton. This is why a fair number of hill photographers quietly end up ordering a personalized rifle sling cut to their own drop length and fitting quick-detach swivels to the lens collar instead of the camera body. Mounting at the collar matters as much as the strap itself; hanging a heavy lens off the camera’s lugs puts all that leverage through the lens mount.

Fit Before Finish

Measure your drop length wearing the jacket you actually shoot in, not a shirt. Two inches of difference is the gap between a lens that sits neatly at the hip and one that clatters against your thigh all morning. Saddle stitching is worth paying for, because a machine lockstitch unravels along its whole length once a single thread goes, and hardware should be brass or stainless if it is going to live in Scottish weather.
One Less Thing to Think About
None of this improves a photograph directly. What it does is get you to the ridge with a shoulder that still works and attention left over for the light. On a hill day, that is the whole game.
