I use OP / Tech Pro straps for some time, both for all my SLR and the weighty camcorder. The belt reduces stress on the neck by the Reassigned device noticeably. He is also quite slippery and it is not running all the time advertising for the camera manufacturer, even with type designation, which thieves facilitates the selection considerably. Since it is a system with OP / Tech, there are practical accessories to the strap adapt to the specific individual needs, such as Verlängerungsstraps or various connectors to the camera. The workmanship is very good.
