The Nikon F-mount SP 150-600mm f/5-6.3 Di VC USD G2 from Tamron is a 4x zoom covering telephoto to super telephoto perspectives. Complementing the long reach is an optimized optical design that features three low dispersion (LD) glass elements to reduce chromatic aberrations and color fringing throughout the zoom range. A conventional zoom lock is also featured to prevent barrel extension during transport. Suiting handheld shooting situations, Vibration Compensation (VC) is a 4.5-stop-effective image stabilization mechanism that helps to reduce the appearance of camera shake for sharper results when working with slower shutter speeds. A ring-type Ultrasonic Silent Drive (USD) autofocus motor delivers notably quick and accurate focusing performance to suit working with fast-moving subjects, and full-time manual focus is also supported for fine-tuned control. The ergonomic and durable metal construction of the lens also incorporates textured focus and zoom rings, and a removable, rotating tripod collar with an Arca-type compatible foot is supplied to better enable shooting from tripods and monopods. Three low-dispersion elements are incorporated to nearly eliminate both axial and transverse chromatic aberrations and color fringing for increased clarity and color fidelity throughout the zoom range. Three separate VC modes are also available to suit various styles of shooting: Mode 1 is a balanced setting for general use, and promotes both a stabilized viewfinder image and stabilized results; Mode 2 is designed exclusively for panning movements; and Mode 3 is optimized to stabilize only during capture without stabilizing the viewfinder image. A conventional zoom lock switch is also featured, which locks the zoom in place at the 150mm position to prevent zoom extension during transportation. The durable metal barrel uses a curved, ergonomic shape for easy handling, and both the zoom and focus rings are textured for improved grip.
