With its precision optics, compact size and wide 75 degree angle of view, the SAL2875 wide-angle lens is an excellent choice for sharp, high-contrast shots when you're working indoors, with people in groups, or in landscapes and urban scenes. It's also ideal when you want a panoramic or inclusive shot with lots of detail. Mounted on your compatible Sony Alpha DSLR camera, this lightweight wide-angle lens provides a near-standard 42mm focal length (35mm equivalent). With wide-angle optics and deep depth of field, this lens creates sharp, high-contrast photos that capture more detail in both foreground and background; its compact size and light weight make it an ideal lens to carry when traveling or for long shooting sessions; and a built-in sliding lens hood protects your optics and makes it faster to switch lenses.
