The SIGMA 120-300/2.8 DG OS HSM SPORTS F/NIKON is a telephoto zoom lens featuring a fast, constant f/2.8 maximum aperture. This lens is the first lens designed under Sigma’s new Sports line of lenses, making it well-suited for fast-moving subjects such as wildlife, nature, aviation, racing, and other similar situations.
Featuring a dust- and splash-proof construction, this lens is ideally suited for use in outdoor and adverse conditions. Its design features rubber focus and zoom rings as well as conveniently located mode switches to enhance usability with the lens. A built-in Optical Stabilizer provides a four-stop-equivalent reduction in the appearance of camera shake, helping to enable better handheld usage and low-light shooting. The Hyper Sonic AF Motor provides fast, smooth, and quiet autofocusing for faster performance that also benefits video recording.
The SIGMA 120-300/2.8 DG OS HSM SPORTS F/NIKON lens, for sale at Foto Discount World, is also compatible with the Sigma USB Dock, which allows you to use the Sigma Pro Optimization software to fine-tune certain lens settings to your own shooting needs. The ability to limit focus range, alter the AF speed, and modify the OS system is afforded through this, as well as the ability to easily update the lens’ firmware.
USB Dock Compatible
The “Sigma 120-300″/2.8 DG OS HSM SPORT F/NIKON lens is compatible with the Sigma USB Dock for fine-tuning and personalizing certain functions of the lens to fit your personal shooting style. A focus limiter can be set to constrain your lens’ focusing distances to suit the distances at which you are shooting. Additionally, this lens features an inner focusing and zooming configuration so the physical length of your lens does not change during use; which greatly benefits the use of certain filters such as a polarizer.
The USB Dock also allows you to customize the speed at which the autofocus system performs, how active the Optical Stabilizer system is during shooting, and allows you to easily update the lens’ firmware.
The built-in OS (Optical Stabilizer) system enables a reduction in the appearance of camera shake up to the equivalent of four stops, resulting in a long lens that can easily be used handheld and low-light conditions. The OS system is divided into two modes; one for general shooting applications, and one that is better suited for panning shots of moving subjects. The OS system can be further adjusted to suit your needs through the use of the USB Dock.
Hyper Sonic AF Motor
The HSM (Hyper Sonic Motor) provides fast, quiet, and smooth auto focusing that is well-suited for use with video applications. This AF motor can also be manually overridden at any time by rotating the focusing ring, giving you the ability to fine-tune image sharpness through manual focusing.
