Anyone using a Gordy strap?
I've been using a Gordy strap for quite some time and have had no issues whatsoever holding it up at eye level. Since you can order the strap at the desired length, I would suggest using a piece of string as a mock up sling tethered to the nex and see what feels comfortable for you. The further away the camera is from your face also means the lower it will hang by your side.
I'm 6'1" and ordered it with a 56" length strap with neck pad and thumb screw for easy attach/remove. Held up to eye level the camera is roughly 40 cm away from my face and it hangs just below the waist. I even could have gone with a shorter strap.
