Camera straps are a very personal thing, and each photographer requires something different depending on their style of shooting — I completely respect that. However, it truly pains me when I see a beautiful new camera slung over someone's shoulder with the strap that came in the box. That strap (with few exceptions) is rarely any good for any style of shooting and is flanked with ugly logos and branding. If you spend a lot of time with your camera attached to you, then do yourself a favor and buy yourself a fine camera strap. It'll make a world of difference — trust me.
One strap worth considering is this one, simply called the Street Strap. It's made from a weaved nylon that is incredible soft and flexible, and wont irritate your skin or catch on your clothing. In addition to being comfortably soft, it's very strong, and never gave me any reason to be concerned about it hanging onto my rather heavy Leica M240.
The ends are hand-stitched with genuine leather to both prevent fraying and also to secure the included metal rings. The rings themselves aren't as thick as some I've seen on some other more expensive straps, but they feel solid and seem to do the job just fine.
The real beauty of the Street Strap is the length. It's made to the perfect length to wear across your body, which is the perfect way to wear a camera on the street. Wear it on one shoulder and you risk it falling off easily. Wear it around your neck and you can strain your neck and easily bump it into things. Across your body is secure, out of the way, and with the right strap, easily accessible when you need it.
The Street Strap is available in two lengths: 46 inch, and 52 inch. I'm fairly short, so 46 inch is perfect for me. The camera rests right at my hip and the strap slides up perfectly when I need to take a shot. Because of how soft and flexible the Street Strap is, it can also wrap around your hand/wrist comfortably to work as a makeshift wrist strap.
If you, like me, spend a lot of time with your camera slung over your shoulder, then this strap is a no-brainer. You'll be amazed at the difference in can make in your shooting comfort.
