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.

Equivalent to 24-450mm in 35mm format, this portable lens covers everything from wide-angle for landscapes and interiors to super-telephoto for sports, wildlife and aviation.Maximum magnification ratio of 1:2 at 70mm for striking close-upsWith a maximum magnification ratio of 1:2 at 70mm, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary provides excellent close-up performance, perfect for capturing flowers, insects and other small subjects in great detail. With a maximum magnification of 1:3 at the wide end and 1:4 at the telephoto end, photographers have access to a huge range of creative expression.Small, lightweight and portableDespite its impressive zoom range of 16-300mm, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary prioritizes high portability, measuring just 73.8mm in diameter by 121.4mm in length and weighing just 615g. This is achieved through advanced mechanical and optical design, including a high refractive index glass element with significant thickness variation and an aspherical lens element.Accelerated AF speed and accuracy with HLA autofocus motorTo help photographers capture even the most fleeting moments, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary uses a High-response Linear Actuator (HLA) motor to achieve high-speed autofocus functionality with excellent drive accuracy.Outstanding optical stabilization powered by the OS2 algorithmInspired by the same technology that powers Sigma's super-telephoto lenses used by professional wildlife and sports photographers, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary features 6 stops of optical stabilization at the wide end and 4.5 stops at the telephoto end. The latest OS2 optical stabilization algorithm provides superior image stabilization to mitigate the effects of camera shake, helping photographers achieve blur-free results without the need for a tripod, even when shooting in low light and at full zoom.Equipped with a zoom lock switch at the wide endThe Sigma 16-300mm F3.5-6.7 DC OS | Contemporary features a zoom lock switch that can be fixed at the wide end to prevent the lens from extending.Dust- and splash-resistant structure and water-repellent coatingDesigned to help photographers work in all environments, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary features a dust- and splash-resistant structure for use in harsh conditions. In addition, the front element features a water- and oil-repellent coating that helps keep the lens free of contaminants.Consistently high image quality across the entire zoom rangeThanks to its advanced optical design with 1 FLD, 4 SLD and 4 aspherical elements, the lens has excellent aberration correction and delivers sharp results throughout the whole zoom and focus range.Engineered to minimize flare and ghostingBy measuring light incidence under all conditions and using advanced simulation technology, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary guarantees superior resistance to flare and ghosting, allowing photographers to capture crisp, clear images in even the most challenging lighting conditions - just as an all-in-one lens should.

The Sigma 16mm f/1.4 DC DN Contemporary is a high-performance, ultra-fast wide-angle prime lens engineered specifically for crop-sensor mirrorless camera systems, including APS-C and Micro Four Thirds formats. It delivers a highly versatile effective focal length, making it an industry favorite for landscape photography, astrophotography, indoor architectural work, and high-quality vlogging. The core of its design centers on a massive f/1.4 maximum aperture that provides exceptional low-light performance and shallow depth of field, allowing creators to drop ambient ISO settings in dim environments while isolating subjects against a smooth, creamy background bokeh. Structurally, the lens is built using Sigma's Thermally Stable Composite (TSC) material to preserve tight optical tolerances during extreme temperature fluctuations, and it features a dust- and splash-resistant rubber sealing gasket around its solid brass bayonet mount to shield internal components from harsh outdoor elements. Optically, the lens utilizes a complex arrangement of 16 elements in 13 groups, heavily packed with three FLD ("F" Low Dispersion) elements, two SLD (Special Low Dispersion) elements, and two glass-molded aspherical elements. This sophisticated layout aggressively controls optical aberrations, sagittal coma flare, and geometric distortion to maintain tack-sharp resolution from the center to the extreme corners of the frame, even when shooting wide open at f/1.4. To satisfy the demands of modern videographers, Sigma integrated an internal stepping autofocus motor (STM) that delivers fast, decisive, and acoustically silent focus tracking, preventing mechanical noise from bleeding into live audio recordings while remaining fully compatible with in-camera lens aberration correction profiles. Weighing in at 14.3 oz (405 g) with a non-rotating 67mm front filter thread, this lens seamlessly balances lightweight portability with professional, studio-grade imaging capabilities.
