An ounce of prevention is worth a pound of cure. In this case you could say that a $55 case is worth $700 in replacement costs. That’s the idea behind these BETA Shell SLR lens cases at least. When I take my camera out, I have a body and three lenses that come with me. I’ve not invested all that much in my camera, so my most expensive one was a little over $125. However, it’s not uncommon for a pro to use one that runs several hundreds (or even thousands) of dollars. Those are the people that would be interested in these cases.
The BETA Shell case consists of a water-tight polymer outer shell, with a couple layers of visco-elastic foam on the inside. Ultimately this means that no water is going to get in, and if dropped, the foam will absorb the shock from the impact. The case is also designed to withstand extreme temperatures, thus providing another level of protection for your lens. They are a bit bulky to carry around, so you may only want to use them when it seems most likely that damage can occur. With prices ranging from $55-$84 (USD), it could be well worth your money to invest in a couple.http://www.youtube.com/watch?v=wYCGuhKggAI&feature=player_embedded
