With its moisture-resistant construction and advanced technology, the Tamron SP 85 mm f/1.8 Di VC USD Lens is a must-have for all FX-format Nikon F-mount DSLR cameras. It has an Extra Low Dispersion element and a Low Dispersion element in the optical design, which reduces unwanted color fringing and chromatic aberrations for a high rate of color accuracy, clarity, resolution, and sharpness. The eBAND and BBAR coatings on the lens minimize ghosting and flare for an increased contrast while working under harsh lighting conditions. Use the rounded nine-blade diaphragm for providing your subjects with a pleasing bokeh quality for a shallow depth of field imagery. You can connect the lens to an optional TAP-In console to adjust the focus setting and update lens firmware. The VC image stabilization function helps in shooting blur-free images. The ring-type USD autofocus motor, along with an optimized USD actuator, offers a fast, yet accurate, focusing performance.
