The A2 features all the same capabilities as it's big brother, omitting just the quick release feature yet still having the adjustability of the special operations military hardware found in the A4. The strap has the same lineage in the morphing department allowing dual or single carry styles. This strap is the favorite of outdoor professionals, such as Art Wolfe, who don't necessarily find themselves in those quick release situations. Also a favorite with run and gun crews of indy film makers were this strap has plenty of "creds" to protect your heavy video gear. The lower risers have enough strap length to even wrap around an 1-1/2" diameter pipe... That covers camera car railings.
