Desiccant packs in airtight boxes sounds like exactly what my camera lenses need. I'm going to do exactly that. I'll still see if vacuum boxes are affordable. Don't wanna be penny wise and pound foolish. The vacuum cabinets should last a good 10 years or more.
I truly appreciate all the tips and advice, folks! SLR camera's have become affordable but lenses have remained expensive as ever. Of course, lenses now have built-in stabilization, something unheard of just not too long ago.
My photography is semi-professional. I shoot mostly empty sites for property development, then composite 3D buildings into the sites. As a hobby, I like shooting photos of festivals as they are always colorful and have lots of people in it. That's where a zoom is handy as I don't have to get too close as some people don't like it.
