Originally posted by geomez I have a DIY hand strap I made out of 2mm cordlette I purchased from REI ($.015 per foot) on my K-3. I just fed it through the strap ring eyelet on the right side of the camera and connected both ends of the cordlette to itself with two barrel knots. I recently did the same thing on the left side of the camera but the diameter of the cordlette loop is only about a centimeter. My reasoning was to have a strong, unobtrusive loop I could connect a DIY sling strap to. I just connect a 1" thick tubular nylon sling (also sold in bulk form REI) to the cordlette with a small carabiner. Works perfectly as a sling strap (given I've never tried a "real" sling strap), and is more quickly removable compared to those I've seen in stores. Mine also leaves the tripod screw unused, which is a plus for me as I always have some kind of plate connected to it.

Note that the red nylon I have is military spec. The climbing spec tubular nylon they sell at REI is smoother in appearance and feel and will glide better than mine (I had mine lying around my house, same with the carabiner). If someone were to undertake this project, it would cost less than $5 in materials.

Originally posted by jamarley I've been using the LensLoop (lensloop.com) which I find extremely well-made, easy to use and comfortable to wear. It might be a bit more than you're looking to spend, but you'll have the satisfaction of supporting a small startup if that's worth anything to you.
If you want to do something like the lensloop yourself, you can buy the seatbelt style nylon at REI and the clips at Home Depot. They should have size adjustment hardware to clamp on to the nylon at REI as well. If you want to connect it to the tripod socket with an eye bolt, I think you'll have to buy one online. I've never seen one of those at a hardware store or outdoors store.
