It features a compact and lightweight design that is ideal for modern mirrorless full-frame cameras. The filter diameter of 67 mm is the same as that of all other Tamron lenses for Sony E-Mount (full-frame). The optical design includes several special glass elements that ensure excellent imaging performance of the lens. The very short minimum focusing distance of just 85 cm further expands photographic possibilities. The lens uses Tamron's newly developed linear motor focus mechanism VXD (Voice-coil eXtreme-torque Drive), which enables fast and very quiet autofocus. The lens housing is weather-sealed, and dirt and fingerprints on the front lens can be easily removed thanks to the water- and grease-repellent fluorine coating. Additionally, the lens is compatible with Sony's manufacturer-specific camera functions, such as Fast Hybrid AF or Eye Detection AF, and offers a range of advanced features that guarantee high user comfort and fantastic image results.
