The Tamron SP 150-600mm f/5-6.3 Di USD Lens for Sony is an expansive telephoto-zoom lens designed for both full-frame and APS-C-sized image sensors. Its 4x zoom design covers standard telephoto to super telephoto perspectives, making it ideally suited to working with a wide variety of subject matter. A USM (Ultrasonic Silent Drive) autofocus motor provides quick and precise focusing performance, with high torque, low response times, and quiet operation to benefit both still and video applications. Additionally, a full-time manual focus mechanism enables manual fine-tuning of focus at any point, even when the AF system is engaged.
- Expansive telephoto-zoom lens is well-suited to nature, wildlife, and sports photography and can be used on both full-frame and APS-C DSLR cameras.
- Three low dispersion elements are integrated into the front group of the lens construction (two in the first group, one in the third) to effectively compensate for on-axis optical aberrations throughout the zoom range, notably with longer focal length positions.
- eBAND and BBAR coatings have been applied to lens elements to minimize lens flare and ghosting in order to maintain high contrast, clarity, and color fidelity.
- A USM autofocus system provides quick, quiet, responsive and accurate focusing performance that is suited to both still image and movie shooting.
- A full-time manual focus mechanism allows for manual focusing at any time; even when working in AF shooting modes.
- The optimized optical design reduces the movement of lens groups during focusing and zooming in order to maintain a relatively compact and lightweight form-factor.
- A redeveloped external finish, with linear patterned zoom and focus rings, enhance the overall handling of the lens as well as its cosmetic appearance.
- A nine-blade circular diaphragm produces an aesthetic out-of-focus quality that is especially beneficial when working with selective focus or shallow depth of field techniques.
- A removable tripod mount is included for use of the lens when working from a tripod.
