Are there cheap alternatives for the large and elaborate "dry boxes" I see listed for use as dehumidified storage cabinets for lenses and other camera gear? I've built up a little collection, live where the summer humidity is often high, and do not run my AC 24/7. My first thought is that this is basically an airtight box with a bunch of dessicant inside. Can't really be that simple, though.

CanonFilter: It appears I have dirt inside the my Canon 28-135mm lens... Rather, it looks to me like it's on the inner optics, and not the prime lens... [more inside]

I'm interested in fitting odd lenses -- and making custom lenses -- to/for digital cameras and digital video cameras. I'm not terribly concerned with the electronic side of things, so you shouldn't be either. What I'm looking for is a crass/crash course in optics -- something (a book, a video, a class, a kit) that will teach me the basics of optics and allow me to force photocopier lenses, telescopes, and microscopes onto unsuspecting recording devices.
