While your dSLR is important, you can't take pictures without lenses. So, it's important to offer equal protection for your optics and camera body. dSLR bodies can go into bags with ample padding, and lenses can go into the Beta Shell.
These lens containers are watertight so you don't have to worry about getting drenched in the rain. They are also capable of regulating temperature so the lenses won't get too hot or cold in extreme climates. The polymer plastic case is also shock-resistant, while the neoprene cushions inside will dampen any vibrations that may damage the optics.
The company makes cases for most popular Canon and Nikon's lenses, and you can check out the list on the product Web site. The shells cost between $45 and $84, depending on the size. Check out the video below to see just how tough the Beta Shell tubes are.
