  • A DSLR lens adapter allows you to affix third-party lenses and lenses of a type your camera and lens mount do not officially offer support for.
  • If your DSLR does not integrate with macro lenses out of the box, try a related adapter on the lens mount.
  • An adapter allows you access to various lenses, which are often much cheaper than branded lenses, such as those available for the Canon EOS, Sony E-mount camera, or Leica M.

Why Learn About Lens Adapters?

Before learning if you can use different brand lenses on your camera, you need to learn about lens adapters. Incidentally, the same goes when learning how to fix a scratched camera lens, as you will have to access that lens. When using an expensive digital camera, such as using a DSLR for video, you want to learn every aspect of its operation, lens adapters included.

Insider Tip

Before buying a lens adapter, ensure it integrates with your camera. Read the item description thoroughly.

This is true even when learning the best Canon camera for beginners. In other words, a lens adapter is a crucial component of your DSLR. Once you learn all about it, you can move on to other things, such as comparing a camcorder vs a camera.

What is a DSLR Lens Adapter?

You can guess what a lens adapter is if you think about it. This is a device that attaches to the lens mount and allows you to integrate lenses and related accessories that would not normally be useable with your camera. If your camera can only access a small number of lenses, this is a good way to increase your options when taking photos.

Benefits of a Lens Adapter

There are a number of benefits to purchasing and installing a lens adapter for your favorite DSLR camera.

Increased Photography Types

Integrating a lens adapter allows for the use of more lenses, thus increasing your photographic repertoire. If the standard design of your DSLR does not allow for a macro lens or a wide-angle lens, for instance, affixing an adapter alleviates this issue. Some camera manufacturers like the “walled garden” approach to lenses, forcing consumers to purchase lenses built by the same manufacturer.

Save Money

Remember how some camera companies like to force you into buying their lenses? That’s because officially branded lenses tend to be much more expensive than third-party options. Once you get an adapter in there, however, you are free to choose budget-friendly lenses. As a warning, you get what you pay for, so shop carefully when buying new lenses.
