If you have a SX70 neck strap (rather than using a generic camera neck strap), you may have noticed that the end of the clip has a curve to it. The factory design clip is a squeeze type that isn’t a straight clasp.
You can clip onto the camera with the clasp curve either way. If you think about it, you could reason that one way might force the camera away from the body, while the other way may allow the camera to hang straight. Is there actually a ‘correct’ way?
Yes, Polaroid does specifically call out on their packaging one way is correct, the other isn’t.
Holding the camera by the bottom, the clap connects from the bottom up, rather than clipping downward. The science behind that? I have yet to find that, but will let you know when I do.
