Lens Caps That Actually Stay Put
For most photographers, the Altura Photo Professional Lens Cap is the top pick because it offers a secure pinch-to-release design and a tethered keeper, making it ideal for on-the-go shooting. Its main limitation is that it is available only in common filter sizes, so less standard threads may not fit.

Common questions
Can I use a lens cap on a lens with a hood attached?
Yes, many lens caps fit over the hood, but some are designed specifically for hoods. Check the cap’s compatibility. If the hood has a pinch cap, you may need to remove the hood to use a standard cap.
What does the mm number on my lens mean?
It indicates the filter thread diameter in millimeters. This is the size of the lens cap you need. For example, a 58mm lens requires a 58mm cap.
Are expensive OEM caps worth the money?
OEM caps from camera manufacturers often guarantee a perfect fit and build quality. Third-party caps can be just as good for less money. Consider your budget and the value of your lens.
How do I clean my lens cap?
Use a soft, dry cloth to wipe away dust. If it is dirty, you can use a mild soap with water, but dry it thoroughly. Avoid harsh chemicals that may damage the plastic or lining.
Why does my lens cap keep falling off?
A worn or incorrectly sized cap may not fit snugly. Check that the cap matches your lens thread size. If it is damaged, replace it. Some caps become loose over time due to plastic fatigue.
Can I use a lens cap on a filter?
Yes, most lens caps attach to the filter thread, so you can place a cap on a filter that is already mounted on the lens. Just ensure the filter size matches.
Are there lens caps that open automatically?
Yes, some auto caps open when the lens extends or when you press a button. They are convenient for quick shooting but may only work with specific lens models.
Do lens caps protect against impact?
Lens caps are designed to protect the front element from dust, scratches, and minor bumps. They offer minimal impact protection. For heavy protection, use a lens hood or a padded case.
Can I use a lens cap as a filter holder?
No, lens caps are not designed to hold filters. They simply cover the lens. Use a filter adapter or holder for that purpose.
What should I do if my lens cap is stuck?
Do not force it. Gently wiggle while pulling to release the grip. If it is a pinch cap, ensure you press both tabs. If stuck due to debris, clean the threads carefully.
Our take
If you want the best combination of security and convenience, choose the Altura Photo Professional Lens Cap. Its pinch mechanism and tether make it a reliable everyday choice. For Canon or Nikon shooters who prefer OEM parts, the Canon or Nikon cap is a solid investment. Budget-conscious users will find the Fotasy cap adequate, but you may sacrifice some fit and finish.
