To get started with your Canon SLR camera, you need a matching lens. Canon EF lenses are suitable for cameras with a full-frame sensor and EF-S lenses for cameras with an APS-C sensor. In addition to Canon lenses, you can also use lenses from Tamron, Sigma, Samyang, or Tokina. You can choose from different types of lenses, from wide-angle for architecture and landscape to telephoto to zoom in far. Make sure to check which lens is suitable for your usage situation.
