Interchangeable lenses for DSLR or mirrorless cameras. You can switch to the lens that works best for wildlife. Fixed-lens cameras like bridge cameras, wildlife camera, compact cameras, and cell phone cameras limit your ability to zoom in and focus on distant birds and animals.
When photographing wildlife, you often can't get very close, so you need a telephoto lens with a long focal length. The definition of a telephoto lens varies by manufacturer, but you should choose a 70mm or larger lens.
You might also consider a zoom lens, which can change the focal length, one lens can go from wide angle to long distance. The range of zoom lenses typically moves between 18 and 200 mm.
A zoom lens might not be as close as a telephoto lens, but it's more flexible if you don't want to keep switching lenses.
