What should you do with your lens cap when you’re taking pictures?
There is a raging debate about the above question in the photography community. The two sides are Cap Keepers, and Cap Tossers.
Cap keepers are concerned, rightly, with protecting the front element of their lenses, and so they advocate keeping the lens cap on when you’re not shooting. Cap tossers say that if you always have a cap on your lens, you won’t be ready for split-second picture-taking because you always have to remember to take the extra step to take the cap off. Besides, say this latter group, you can keep a UV or Sunlight filter on your lens, and that’ll protect your lens. They, too, have a point.
Some people take the middle ground, and keep their caps in their pockets while they shoot. This, however, is a very efficient way to pick up pocket lint and transfer it to the front of your lens, which is not cool. If you keep it in your pocket, it could fall out, get washed with the laundry, or taken out and put on a table or something…and is lost.
I’d like to propose a very inexpensive compromise: The Cap Keeper. Made by Sima and sold under the Adorama brand name, it’s simply a string that firmly attaches on one end to the outside of your lens cap, while the other end is attached to your camera by looping the string through the camera’s strap holder. While you shoot, the cap hangs from your camera--a visual reminder to put it back on when you’re done. When it’s not hanging, it’s on the lens, so you’re more likely to see the string and remember to take it off and not have one of those embarrassing “hey, man, your cap’s on the lens” moments.
Best part? It costs two bucks.
