I keep the lenses on the boards with cable release attached.. I have the Photobackpacker pack and lens cases which are excellent.
Someone mentioned Gnass products. I have a couple for their film holder cases which are excellent. However, I ordered a focusing cloth from Gnass in September 2007. They charged my credit card, never sent the product, and have not responded to my email. The last I looked at the website, it appeared defunct.
For other purposes I have a large Pelican case on wheels that holds everything with padded dividers.
