After BlackRapid's success, another strap contender LumaLoop is entering the fray hoping that it can also provide an improved camera strap, one of photography's perennial Holy Grails.
James Duncan Davidson (a photographer) designed and made the LumaLoop, an across-the-shoulder strap with a quick-release lanyard, whose main claims are comfort and flexibility.
Those who have already used the strap report they like how the camera can be used while slung over a shoulder, and can quickly be released by squeezing the buckle. When not in use, the camera dangles at one's waist, and can remain there all day long.
The LumaLoop is $60 and comes in three sizes. Each strap comes with a lanyard.
From what I've seen on its website, LumaLoop uses the same general idea for an across the chest bandolier strap as BlackRapid, with the twist of having a quick release lanyard-to-buckle instead of a carabiner.
Here's a previous post as to how I "readjusted" my BlackRapid straps to avoid any unforeseen accidents.
