There’s no single camera strap that’s best for DSLRs. But there are criteria that need to be met. Unless you’re shooting with one of the smaller and lighter DSLRs and a lightweight lens, be sure to choose the sturdiest camera strap you can find. Check the maximum weight the strap will support and, from there, find one that offers a padded strap or look at one of the supports that clip the camera onto your body to avoid strain and sore muscles. You want to take care of your photography equipment and your body, too.  Also, a quick release—where the camera can be detached from the strap with a single motion—is useful when you need the flexibility of hand-holding the camera. You may be kneeling down to grab a macro shot where the strap would interfere with you getting the right angle or may want to position the camera in a way that would be impossible while it’s attached to the strap.
