Sigma introduces a new zoom lens for APS-C mirrorless cameras with an f/1.8 aperture throughout the entire zoom range, the 17-40mm f/1.8 DC Art Lens. Featuring prime-like optical performance and video-friendly design and functionality, its wide-to-normal focal range means a lighter kit bag without surrendering image quality. The lens features a total of 17 elements in 11 groups, with four aspherical and four Special Low Dispersion elements to minimize flare and ghosting and suppress various aberrations. This results in an optical performance that meets or exceeds that of other Sigma Art lenses, including the 18-35mm f/1.8 DC HSM Art lens. Along with its 11-blade, rounded diaphragm, the design promotes sharpness and a large, smooth bokeh when used wide open. In addition to the f/1.8 maximum aperture, the lens also maintains an 11" minimum focusing distance across the entire zoom range. It achieves a maximum magnification ratio of 1:4.8 at its longest focal length, increasing depth of field and versatility in tight spaces.
The 17-70mm F/2.8 Di III-A VC RXD (Model AFB070S700) is a large aperture everyday zoom lens for Sony E-mount APS-C mirrorless cameras. Fast, sharp, quiet, and small—this new APS-C zoom lens is extraordinarily versatile and perfect for everyday photography. The lens was created to achieve a broad zoom range and excellent image quality. With a focal length range of 17-70mm (a full-frame equivalent of 25.5-105mm), it’s the world's first 17-70mm F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras. The 17-70mm F2.8 includes Tamron's proprietary VC (Vibration Compensation). When shooting video, by utilizing AI technology, image stabilization performance improves compared to conventional models. Designed specifically for use with APS-C mirrorless cameras, the lens is light weight and compact, even with VC. Its small size and versatility make it a great choice for outdoor, travel and vacation photography, where compact camera bags are preferred, and of course for daily use. Additionally, photographers / users can take advantage of a close working distance. It features an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide-angle end and 0.39m (15.4 in) at the telephoto end. The lens is equipped with Tamron’s RXD (Rapid eXtra-silent stepping Drive) AF drive system, a high-speed, precision stepping motor unit. It also incorporates a wide variety of other features, including Moisture-Resistant Construction and Fluorine Coating for added durability. In your everyday life and on your trips to distant places, this lens captures all the excitement and discoveries with the finest possible detail.
