Product Details
Tamron B091S700 16-50mm F/2.8 A Di III-A Zoom Lens for Sony E Mount
The Tamron B091S700 16-50mm F2.8 A Di III-A standard zoom lens for Sony E-mount APS-C mirrorless cameras combines wide-angle-to-mid-telephoto coverage with a constant F2.8 maximum aperture and VXD linear-motor autofocus. Its versatile range suits landscapes, indoor family groups and portraits without changing lenses. Close focusing to 0.15m at the wide end opens up flowers and cafe details, while BBAR-G2 Coating reduces flare and ghosting in backlit scenes. A compact, lightweight build makes it a practical everyday companion for travel photography and video.
Key Features
16-50mm Versatility, From Groups To Portraits
Move from 16mm wide-angle views to 50mm mid-telephoto framing as the scene changes.1 At the wide end, capture broad scenery, architecture or an indoor family group when there is little room to step back. Zoom toward the longer end for everyday snapshots and intimate parent-child portraits, keeping one lens on the camera throughout the outing.
Constant F2.8 For Low Light And Soft Backgrounds
Keep the maximum aperture available as you zoom, whether you are photographing an indoor family moment or a portrait at dusk. F2.8 gives you room to use faster shutter speeds with active children and moving subjects while separating them from softly rendered backgrounds.2 The seven-blade circular diaphragm helps keep out-of-focus highlights smoothly rounded.3
A Lightweight 305g Travel Companion
The Sony E-mount version weighs 305g, helping reduce the carrying burden during a full day of sightseeing or an outdoor outing.4 Selected barrel materials, including metal, and an internal design focused on structural rigidity support a compact lens made for everyday carrying.
VXD Autofocus For Spontaneous Moments
When children or pets move unpredictably, fast, precise focusing and subject tracking help you keep up with the moment. The Voice-coil eXtreme-torque Drive linear-motor mechanism also keeps operating noise low, making it useful for still photography and video in settings where sound matters.5
Wide-Angle Video And Tamron Lens Utility
Film yourself without losing the surroundings that tell the travel story. Wide-angle framing suits selfies and vlogging, while the compact build balances comfortably on a separately purchased gimbal or shooting grip. Tamron Lens Utility support lets you assign practical video-related functions for this Sony E-mount lens.6
0.15m Wide-Angle And 0.29m Telephoto Close Focus
Get near flowers, food and cafe details while keeping a sense of place in a wide-angle composition. Minimum focusing distances of 0.15m at wide angle and 0.29m at telephoto give you different ways to frame nearby subjects. At the longer end, use softly separated backgrounds for intimate details such as a sleeping child's portrait.
Toned Profile Next And A Tether-Ready Cap
Toned Profile Next introduces a clean, mechanical-style exterior while retaining practical handling. The front cap has strap holes on both sides for an optional, commercially available tether cord, so you can keep it close instead of repeatedly putting it in a pocket. A cord is not included.7
BBAR-G2 Coating And Outdoor Protection
Second-generation Broad-Band Anti-Reflection coating helps preserve detail and contrast when light comes from behind your subject. Barrel seals and a waterproofed USB Type-C connector port support moisture-resistant construction for outdoor use. On the front element, fluorine coating repels water and oil, making dirt, moisture and fingerprints easier to clean away.
