You use lens adapters if you want to mount a lens with a different mount on your camera. This makes it possible to use a Canon SLR lens on your Sony system camera. Lens adapters can also have other functions, such as an extra setting ring or mounting older SLR lenses on a new system camera. This allows you to continue to use your lenses with an outdated mount on your new system camera. Make sure to check which mount your camera has and which mount the lens has. Below, you can find our entire assortment of lens adapters.
