On a DSLR camera, you can identify the purpose of a lens by looking at its focal length and aperture. Lenses with shorter focal lengths (e.g. 18mm) are typically wide-angle lenses, which are great for capturing landscapes and architecture. Lenses with longer focal lengths (e.g. 200mm) are usually telephoto lenses, ideal for shooting distant subjects like wildlife or sports. Additionally, the aperture of a lens (e.g. f/1.8) can indicate its low-light capabilities and ability to create a shallow depth of field for portraits or artistic shots. Understanding these characteristics can help you choose the right lens for your specific photographic needs. **
