Originally posted by snake What concerns me most about OpTech's stuff is the weight carrying capacity, as well as multple points of failure, even if by user error, such as those clips and the thin cord by the camera end.
The foam neck pad on mine has frayed a bit at the edges. Just cosmetic and I see some of the newer ones are now wrapped and stitched at the edges. But the nice thing about it is because of the clips you can replace the neck pad without changing out the rest of the rig. Or have different pads for different uses.
Been using mine for almost two years and see no issues with the support strings. I use a DA*16-50 on k-5 most of the time and no worries. If you are using a heavier lens then it might be a concern but I wouldn't be carrying anything heavier on a neck strap anyway.
The clips are rock solid and absolutely the least of my concern. I don't know what the weight capacity on them is but it is far above anything you carry as camera gear. The strings at the camera end are thin, at least on the model I have but after almost two years of use I still do not see any wear. And they make thicker ones if you want, for different camera attach systems.
If you use it as an around the neck pad then you have a single point failure at the strings. but if you use the sling strap system you have both strings independently attached to the sling strap so both would have to fail for the camera to fall. The clips are single point failure but I cannot imagine breaking one of them. And they sell secure ties to prevent them coming loose by accident if that is a concern.
