Key Features
All-in-One Convenience with Wide Aperture
Covering an expansive 28–200mm focal range, this lens is perfect for photographers who want one lens to do it all. From capturing sweeping wide-angle scenes to detailed telephoto shots, it offers the flexibility needed for everyday use, travel, and documentary work. The standout feature is its f/2.8 aperture at 28mm, which is rare in superzoom lenses and allows for better low-light shooting and subject isolation.
Compact and Lightweight Design
Despite its broad zoom range, the lens weighs only 575g (1.27 lbs) and measures just 117mm (4.6 inches) in length. This makes it an ideal companion for mirrorless shooters who want to stay mobile and minimize gear while maximizing versatility. Whether you’re hiking, traveling, or shooting handheld, the 28-200mm keeps your setup light and agile.
Excellent Optical Performance
The optical design consists of 18 elements in 14 groups, including LD (Low Dispersion), XLD (eXtra Low Dispersion), and aspherical elements, which help suppress chromatic aberrations, distortions, and flare. The result is sharp, high-contrast images throughout the entire zoom range, from wide-angle to full telephoto.
High-Speed, Quiet Autofocus
The built-in RXD (Rapid eXtra-silent stepping Drive) stepping motor provides fast, smooth, and near-silent autofocus operation. This makes the lens equally suitable for both still photography and video recording, with seamless focus transitions and reliable subject tracking—even in continuous AF modes.
Travel-Ready Durability
Designed with practicality and durability in mind, the 28-200mm f/2.8-5.6 features a moisture-resistant construction and a fluorine-coated front element, protecting against fingerprints, water, and dust. It’s built to withstand the rigors of outdoor use and changing environments—making it ideal for photographers constantly on the move.
Close-Up Capabilities
Despite being a zoom lens, it also performs impressively in close-up shooting. The minimum focusing distance is just 0.19m (7.5″) at 28mm, allowing for semi-macro capabilities with a maximum magnification ratio of 1:3.1, which is great for capturing small objects, textures, or creative close-ups without switching to a dedicated macro lens.
Conclusion
The Tamron 28-200mm f/2.8-5.6 Di III RXD (A071) is an exceptional all-in-one lens that breaks new ground in terms of portability, performance, and aperture range. Whether you’re a travel enthusiast, casual shooter, or content creator who values simplicity and quality, this lens is an ideal solution. With outstanding image quality, quiet AF, and an ultra-wide zoom range, it offers everything you need in a single lens—without the bulk or complexity of a multi-lens kit.
