OP/TECH USA Super Classic sling is a streamlined sling-style strap for mirrorless and SLR cameras using heavy lenses. The cameras may be getting smaller, but the lenses are still packing on the weight. The super Classic sling offers the best of both worlds-compact design with added reinforcement and support to handle the extra weight. As many photographers prefer to keep the attachment on the camera as short as possible, OP/TECH USA Uni-Loop connectors fit the bill perfectly. They secure easily on the camera and glide smoothly up and down the sling for rapid access to the camera. As the Uni-Loop connectors attach to the normal connection area on a camera, there’s no need to give up the tripod mount. This keeps the gear in a more accessible position instead of hanging upside down which can put more torque and pressure on the camera housing and lens mount Area. Most cameras will attach with a single Uni-Loop connector (rated at over 146 lbs. ); However, cameras with a second attachment point on the right side, or cameras with Battery grips can use two. An adjustable “stop” lets the photographer configure the position where the camera hangs best. The quick disconnects allow one to change from a sling configuration to a more conventional neck/shoulder strap by simply attaching OP/TECH USA extension system connectors (sold separately). this makes the strap extremely versatile so that it changes along with the photographer’s needs. The comfortable neoprene pad features a non-skid surface backing which really grips to the shoulder. It can be worn on either the right or left shoulder which increases its versatility over most other slings on the market. The internal control-stretch system combined with a comfort-stretch binding assures a durable strap that offers maximum comfort and support. The quick adjust feature allows the length to be instantly shortened or lengthened as desired.
