My storage system is a work in progress -- which is pretty sad given it's been going on for about fifty years.
I have a Lowepro Microtrekker backpack with my Canon A-1 and "most" of my FD lenses. I have a Computrekker with "most" of my Bronica gear in it. I have a Canon EOS-<achoo! Cough> which resides in one of two Think Tank products. And then I have some plastic shoe boxes with one camera and most of its accessories assigned to each box. Unfortunately, I have yet to find one place large enough to hold and organize all this stuff. So currently its strewn-hither-and-yon with some light hints of a better future. Some of my bizarre photo interests have resulted in adding an alarming number of light stands, softboxes and a background stand that have further overwhelmed the closet space. Alas, in about forty years here, i am close to making this entire place a 1600 square foot walk-in closet.
"Good luck" [hangs head in shame ....]
