FAQ About Lens Caps

Whether you're a professional photographer or just starting to get into the craft, you'll need a lens cap to ensure your equipment stays in pristine condition. Not sure what to look for in a lens cap? Here are the answers to some of the most common questions you may have.

What benefits does a lens cap provide?

The optical elements of camera lenses are fragile. To keep them protected, you'll need to use a lens cap. Considered a photography essential, lens covers are designed to fit over the ends of your lens to safeguard it against fingerprints, scratches, dust, and minor impact.

What types of lens covers can I choose from?

A front lens cover is placed over the front element, the part of the lens aimed at the object you want to capture. A rear lens cap protects the rear element and mount of your lens, and is used when you remove your lens from the camera body. You'll only need a rear lens cap if you plan on using a camera with interchangeable lenses.

What should I consider before buying a lens cap?

Most cameras and lenses come with a standard lens cap. However, due to their small size, lens covers can be easy to lose. Before shopping for a replacement front lens cap, you'll need to find out the diameter of your lens in millimeters. This measurement can be found on the front of the lens. Unfortunately, rear lens caps aren't as easy to size. Be sure to check your lens manual to find out what replacement caps are compatible.
