Here’s a “carry around” tripod for your carry around lens and camera: The ZipShot is a “compact, ultra-light tripod” by Tamrac that has aluminum-alloy legs that resemble the collapsible poles used in tents. While it’s not very useful in windy situations, or with heavy professional gear, it might suffice for most ordinary uses and lighter cameras (supposedly it can hold up to 3lb). The biggest benefits are obviously weight (11oz) and setup time. Here’s a video showing how quickly you can set the thing up:
The ZipShot costs $50, and can be found at most camera equipment retailers online (just search for “zipshot”).
