with all the cameras and lenses in the pit its no problem to loose a lenshood.
Surfing on the web I found a nice site to save money by replacing the lost lenshood.
Have a look on http://www.lenshoods.co.uk/
“This site contains PDF documents that can be printed and cut out to make lens hoods for a variety of 35mm and digital SLR camera lenses. Lens hoods give better quality photographs by reducing flare caused by nonimageforming light.”
I thinks its really a good idea.
