When I bought my DSLR Camera a few years ago I read in one of my magazines about protecting the lens (which in my case was roughly the same price as the camera body) to buy a $15 UV filter, in case of an accident the UV filter would break first and saving the lens from being damaged. Well this happened to me yesterday when I jumped in a boat and travelled along the beautiful Noosa river which is on the Sunshine Coast, Queensland, Australia. I am not too sure how it happened, but it did. Thankfully I did have a UV Filter on my lens.. So if anyone is reading this and has such a lens which they want to protect and have not bought a UV Filter go out and buy one now !!!
