If a lens is even remotely important to me I keep it with front and back caps in a padded camera storage bag when I am not using it. In the original case if I have it. Or in my 3 Tamrac zip cases if I shoot with it a lot. Most of my AF lenses are in those with lens caps in place. That being said I get lenses sometimes that come lacking front and back caps and I'm not made out of money. I honestly can't afford to buy more lens caps the way they are priced. Even the generic caps can be pricey. I use whatever I've got and of course I'm always happy to see any extra lens caps that I come across otherwise. I love it when I find a few floating around in a bag of gear at Goodwill, for instance. I clean them up, dip them in some bleach for a few minutes, rinse, dry, and gleefully use them on any lens that will fit no matter what it says on the lens cap. No unknown lens cap goes on any lens I own until it's been well cleaned though.
Ditto any new lens. It gets a through examination and a cleaning before it gets stored anywhere near any of the others. No dust or grunge is allowed around here. My lenses are clean, clean, always. That's why I have lens cleaner and a blower. I don't abuse a lens while I'm cleaning. I'm very careful but nothing is allowed to accumulate once I have a lens. I can't help it if I get a lens and there is a bit of dust already in it. But I don't allow any more to accumulate if I can help it. A lens that leaves my hands usually is in better condition when it goes than when I got it actually.
So far I have usually been able to scrounge back caps but I have had to settle for using an AV filter as a lens cap on 3 or 4 of my cheaper C/Y lenses and one of my lenses is just in the black hard case it came in with a filter on it but with the lens back up. That case is one of the old style ones, snaps shut, and the lens itself is the equivalent of a coke bottle so I don't feel too guilty about using it's caps on a better lens. The better lenses have priority, obviously. I don't just leave my lenses lying around though to get dusty or worse. I clean my lenses regularly too. I'm totally anal about not touching the glass, about putting the caps back on, about making sure that I don't put a lens or a lens cap on anything that might get dust inside my lenses. Dust and fur I live with. But my lenses don't, not if I can help it.
If a lens has no caps in my house it's at least wrapped in something that won't shed while it's stored and it's in a bag away from dust. I do have lenses that came on cameras that I just don't have caps for. Most of the ones I don't have caps on are in the sale box, bagged though. I'm not going to hand someone a lens if I can help it though without a quick clean and some wrapping to keep it safe until they can find some. I can't afford to give up my caps but I still wouldn't want to be handed a filthy or broken lens, would you? Anything with fungus goes out almost as fast as it comes into my house. Otherwise I use all my lenses fairly regularly to make sure they get aired out and get some sun. I have desiccant pouches in the bags. I do everything I can to keep my lenses nice.
I am realistic about it. I live in a tropical climate. It's humid and hot and there's only so much you can do. I've not had (knock on imaginary wood) a problem so far with any of my major lenses but if I did I suppose I'd send them away to be cleaned if I did. I'm not about to lose a really good lens like a Tak if I can help it, but otherwise if they're easily replaceable I'm not that worried. It's probably a good thing that a lot of my lenses are $5-20 cheapies though. Losing a Ricoh lens or a DSB wouldn't make me cry too hard. Actually my AF lenses are pretty easily replaceable if it came down to it. I don't have $300 AF lenses. It's the Taks I worry a lot about particularly the 105mm. But those like I said I'd probably have cleaned before I'd toss one.
I clean my bodies too fairly regularly. I don't let dust accumulate on any of my gear, not just my lenses. First thing I do when a new camera hits the collection usually I give it a quick clean then do the seals if necessary. If a camera is sitting grungy in a box around here it's because it's broken. If it's not it's totally clean and it's got a clean bag to go in. But yeah, I am totally into lens (and body) maintenance and making sure caps are on. Sometimes if I am changing lenses a lot I'll leave a lens face down in the padded bag and just close the top of the bag no caps so it's convenient. But that's in a padded bag that I vacuum out every once in a while and only for a few minutes while I am shooting heavily. The moment I have time, the caps go back on. I would never just leave a lens out parked on whatever surface with no cap. The very thought gives me the shivers, lol.
For the record I'm not a total neat freak otherwise. Even my dolls get some dust on them from time to time and I never seem to be able to catch up with the fur clumps around here. We have animals. There's dust and sand all over. I live in a tin can house that is not sealed well to the elements. A certain amount of crud is just inevitable. I'm anal about keeping it off the dishes and out of my food, off the camera gear but otherwise? I clean as much as I can stomach and that's it. I'm no Martha Stewart type and I generally like to spend more time doing more important thing than swinging a broom.
