I like the Pelican Case 1500 with Pluck & Pull for my 12-15 lenses that keep rotating because I'm trying out a lot of new lenses and selling some old (and who knows when I might get the 75mm for a present? :tongue. They're all similar diameter but I don't want to have cap up in the foam. I have a few pancakes, a few legacy lenses, some with some without adapters, a few medium sized, etc. Right now they're all like this in little pouches but I want them all together in foam. The guy below has his Pluck & Pull foam set up nicely but if that was my setup next month I'd replace one or two of those with something that's probably a different size. The obvious advice would be the 1500 case with rearrangeable dividers. But I don't like A) how messy it looks and B) the way the smaller lenses in any given column will rattle around (similarly, I don't like TrekPak). The only idea I can come up with is, since the lenses are all the same diameter, plucking three long rows left to right across the case and store the lenses all horizontally cap to cap to cap. I could stick a round piece of foam between each if needed, and I could add/remove lenses at will. Wouldn't be the prettiest, however, and whenever I take a lens out I'd have to fill the space with something to keep the rest of them from moving around. Any better ideas?
