For many discriminating photographers it is a lens that will stay on the camera most of the time. Its versatile 24mm to 70mm zoom range covers a wide gamut of shooting situations, and its extraordinary sharpness and contrast are fully retained at all focal lengths and apertures. Whether you're shooting a tight indoor scene at 24mm, a portrait at 70mm, or anything in between, you'll feel and see legendary Carl Zeiss quality in every shot. • Weight (approx): 955 g • Dimensions (Dia. x L): 83 x 111 mm • Max. magnification ratio: 0.25x Contrast (%) Contrast (%) 50 Contrast (%) Contrast (%) M mode, 1/500 sec., F8, -1.7 EV, ISO 200, Sunset Creative Style, D-Range Optimizer Lv2; Photo: Kentaro Fukuda Wide-angle prime Distagon T* 24mm F2 ZA SSM SAL24F20Z At 24 mm - Open 100 80 60 40 20 0 4 8 12 16 20 Distance from optical center of lens (mm) Two ED glass elements and two aspherical elements for superior image quality Carl Zeiss T* coating effectively controls flare and glare Quiet, responsive internal SSM (Super Sonic wave Motor) autofocus drive Focus ring with auto clutch does not rotate during autofocus 9-blade circular aperture for attractive defocusing Aspherical lens ED glass At 24 mm - F8 100 80 60 40 20 0 4 8 12 16 20 Distance from optical center of lens (mm) Representing the wide end of the A-mount Carl Zeiss prime lens range, the 24mm focal length of this model provides a wide perspective on 35mm full-frame format cameras, and a closer-to-normal equivalent focal length of 36mm on APS-C format cameras. Photographers who value a singleprime approach to general shooting will love this lens, as will those who appreciate the subtle but tangible quality advantage that a first-class prime provides. Use it indoors, on the street, or in the wild for images that can bring your artistic vision to life. In addition to unimpeachable optical performance and refined overall handling, this lens offers particularly responsive, quiet autofocus operation and a minimum focusing distance of just 19 centimeters that lets you explore your subjects at close range. • Weight (approx): 555 g • Dimensions (Dia. x L): 78 x 76 mm • Max. magnification ratio: 0.29x 51
