Sony's 24mm f/1.8 ZA E-Mount Carl Zeiss Sonnar Lens opens up a new world for owners of NEX cameras. The equivalent of 36mm in full-frame or 35mm format, this lens is a versatile medium wide-angle focal length with superb Zeiss Sonnar optical design. The extremely wide maximum aperture of f/1.8 is ideal for shooting under low-light conditions, and with the seven blades that form a near-circular aperture, it can also create photos with lovely shallow depth-of-field (which provides a powerful sense of space).
