Kerrkid....why would it be an issue? 11mm/circa 1/2" straps have been standard for decades. Neither a Leica M nor Rolleiflex are particularly heavy cameras. The narrow straps take up little room in any bag and are comfortable when/if you loop them around the wrist. Add to that, they're discreet compared to wide, coloured straps or the wide ones emblazoned w Nikon or Canon.
