Lenses

Interchangeable lenses come in a huge array of types for shooting different kinds of subjects

IN GENERAL, the easiest way to expand the kinds of pictures you can take is by buying different types of lenses. For example, telephoto lenses let you zoom in on distant subjects, while macro lenses enable close-ups of small objects. Largeaperture lenses allow you to isolate subjects against blurred backgrounds, or shoot in low light without having to raise the ISO too high. Meanwhile, all-in- one superzooms cover a wide range of subjects, but usually with rather lower optical quality.
