The Sony Carl Zeiss Sonnar T* E 24mm F1.8 ZA is a wide-angle APS-C prime lens for the Sony E-mount, announced by Sony in December 2011.
Build quality The lens features a thin aluminum shell over plastic internals and a detachable petal-type lens hood. The lens showcases a minimalist black exterior with a Zeiss badge on the side of the barrel, nearly identical to Sony's Zeiss-approved 55mm F1.8 full-frame lens.
Given its unusually high 1:4 (0.25x) image reproduction ratio, the 24mm lens can be considered a pseudo-macro lens.
Its autofocus is fast and silent.
Image quality The lens is exceptionally sharp, on par with Sony's other Zeiss-approved prime lenses. When at its maximum aperture of f/1.8, the lens exhibits creamy smooth bokeh. The lens suffers from mild vignetting and chromatic aberration, which can be seen toward the outer edges of the frame.
