Black rapid rs7 +1. Just brought a black rapid rs7 after previously buying a lowepro strap.have to say the rs7 is brilliant, takes the weigh of a d7000,grip,300mm f4 and 1.4tc very well, hardly know its there. If you are thinking of getting a heavier setup than the black rapid rs7 is worth the investment. Brought the black rapid over the QStrap mainly due to the likely better quality. the black rapid can be mounted to either the tripod collar or the camera tripod mount so its underneath the camera and out of the way. Can understand people going for the QStrap for the price though, the rs7 is expensive for what is but it down to you whether you think it's worth paying.
