The optical construction features 25 elements in 16 groups. The generous and effective use of special lens elements ensures exceptional image quality. This includes one XLD (eXtra Low Dispersion), five LD (Low Dispersion), and two Hybrid Aspherical lens elements. These elements thoroughly control aberrations, including axial chromatic aberrations. As a result, users can enjoy exceptionally high resolving power across the entire image, from edge-to-edge.

The 150-500mm F5-6.7 features VXD linear motor autofocus mechanism. VXD delivers high-speed and high-precision movement and ensures responsive performance. Even when shooting at 500mm, the lens provides fast and accurate focusing from near to far. Also, the high-performance focus tracking allows successful capture of fast-moving subjects. Superbly quiet, the linear motor also reduces drive noise and vibrations produced during focusing (as compared to a conventional drive system), making it ideal for shooting both still photos and video in low-noise environments.

This compact 150-500mm F5-6.7 is equipped with TAMRON’s VC mechanism to deliver excellent image stabilization performance, thereby efficiently reducing image blur caused by camera shake. This functionality supports handheld shooting of scenes in low light, such as evening and indoor, without the use of a tripod. Due to the design and functionality of the Nikon Z camera, the VC (Vibration Compensation) should be toggled ON or OFF directly on the camera body. As a result, there is no dedicated switch on the lens for this purpose.

The 150-500mm F5-6.7 offers exceptional close-up shooting capabilities for an ultra-telephoto lens. The MOD is 0.6m at the 150mm end and 1.8m at the 500mm telephoto end. The maximum magnification ratio at 150mm is extremely high at 1:3.1. Users can shoot powerful telephoto-macro images of subjects while maintaining a reasonable shooting distance.

Tamron's Moisture-Resistant Construction provides a protective barrier that helps prevent the lens from being affected by moisture or rain, ensuring safer use in outdoor environments. In addition, the Tamron Fluorine Coating, is a special coating on the front lens that repels water and oil, making it easier to wipe off smudges, fingerprints and dirt, and also helps prevent condensation on the lens surface. Together, these features enhance the durability and usability of the lens in challenging conditions.
