The Tamron 24mm f/2.8 Di III OSD M 1:2 is a sleek, lightweight wide-angle prime lens built specifically for full-frame Sony E-mount mirrorless cameras — and equally capable on APS-C bodies where it delivers a 36mm equivalent field of view. Its compact profile makes it a natural companion for travel and street photography, while the f/2.8 maximum aperture keeps available-light shooting well within reach without adding bulk.
Beyond its wide-angle versatility, this Tamron prime doubles as a capable close-up lens thanks to a 1:2 half life-size maximum magnification and a 4.7-inch minimum focus distance. Three LD elements, one aspherical element, and BBAR multi-layer coating work together to deliver sharp, high-contrast images free from chromatic aberration, flare, and ghosting — all wrapped in a moisture-resistant body with a fluorine-coated front element for all-weather confidence.
