How do you choose a lens for a SLR camera?
Choose the right lens mount
Each lens has a unique lens mount, so it's important to keep that in mind. The lens mount it the end of the lens that you twist on the camera. For example, you can twist the lens of a mirrorless camera onto an SLR camera. In addition, it's smart to keep the camera brand in mind during your purchase. You can't mount a Nikon lens onto a Canon camera. Always check the lens mount and camera brand before your purchase.
Determine which lens suits your usage situation
The type of photography you want to do is important for your lens choice. Do you want to zoom in a lot to take a a photo of a wild animal? Choose a 100-400mm telephoto lens, for example. Do you often take photos in dark areas? Choose a lens with a large maximum aperture for more exposure, such as f/1.2 or f/1.8. For portrait photography, you can use a 35 or 50mm lens.
Choose a zoom lens or prime lens
When you know which subjects you want to take photos of, it's time to determine if you need a zoom lens or prime lens. Zoom lenses are more versatile than prime lenses. Do you want to take photos of broad landscapes one day, and small details the next? That's possible with a zoom lens. You can use a prime lens when you're sure you want to take a photo of something specific. Prime lenses can't zoom. This way, they're light-sensitive. They have a fixed focal point, which results in a high image quality.
