Smart Design Inside and Out
The Tamron SP 85mm f/1.8 Di VC USD Lens, a short-telephoto prime is an ideal focal length for portraiture. Designed for Canon EF, Nikon F (FX), Sony/Minolta Alpha DSLRs. Using a single Low Dispersion element and a single Extra Low Dispersion element into the optical layout, this lens is adept at diminishing chromatic aberrations and color fringing for a magnitude of clarity and color accuracy, along with sharpness and enhanced resolution. Also BBAR and eBAND coatings have been applied to cut down on flare and ghosting for enhanced contrast when shooting in strong lighting environments, and a rounded nine-blade diaphragm is a contributing factor to a pleasing bokeh quality to take advantage of shallow depth of field images. Classic in focal length yet optimized for the recent variety of high-resolution DSLRs, this portrait-length prime fuses a familiar perspective with contemporary performance.
Complementing the optical assets, this lens is also symbolized by Vibration Compensation image stabilization, which diminishes the appearance of camera shake as much as 3.5 stops for sharper handheld photography. Also lending a hand in creating sharp images, a robust ring-type USD autofocus motor complete with an optimized USD actuator is employed for noticeably fast and accurate focusing operation. This focusing system also adapts to full-time manual focus control for fine-tuned fidelity. A moisture-resistant physical build allows it to be used in difficult environments and the front element has also gotten a fluorine coating to protect against smudges and moisture from infringing upon image quality. In addition, this lens is compatible with the available TAP-in Console for fine-tuning focusing operation and updating the lens' firmware.
A near perfect portrait-length prime, this 85mm lens is designed for full frame DSLRs, and is also compatible with APS-C cameras where it will deliver a 127.5mm (35mm equivalent focal length).
Fast f/1.8 maximum aperture is an advantage while working in low-light situations and also provides extensive control over focus arrangement for enhanced separation of subjects from the background, along with the capability to produce selective images.
LD (Low Dispersion) and XLD (Extra Low Dispersion) elements of glass are used in the 13 elements, 9 groups optical layout, and add to a marked curtailment in chromatic aberrations and color fringing all through the aperture range.
eBAND (Extended Bandwidth and Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) coatings have been used on lens elements to curtail surface reflections and minimize lens flare and ghosting for enhanced contrast and color accuracy.
Vibration Compensation (VC) image stabilization is built into the lens' design to diminish the appearance of camera shake as much as 3.5 stops for sharper handheld photos in low-light situations.
Ring-type USD (Ultrasonic Silent Drive) motor Along with an optimized USD actuator are used for fast, precise, and stealth quiet autofocus performance that is an advantage to both still images and video recording. This motor also allows full-time manual focus control without shifting into a dedicated MF mode.
Moisture-resistant layour uses seals around the lens mount and additional areas to create an advantage when working in inclement weather. In addition a fluorine coating has been used on the front lens element to fend off water, fingerprints, and smudges for easier to clean lens surface.
Rounded nine-blade diaphragm provides a pleasing out-of-focus quality when shooting with shallow depth of field styles.
An electromagnetic diaphragm system is employed to ensure more consistent exposure returns, especially at increased continuous shooting rates.
Harmonious with the available TAP-in Console for updating the lens' firmware along with adjusting focus settings using the TAP-in Utility software.
SILKYPIX Developer Studio software specifically for Tamron is enclosed with the lens, which, aside from employing basic raw processing and image adjustments, goes a long way to specifically calibrate for various aberrations, including distortion, color fringing, and peripheral light fall-off, making use of dedicated optical data from Tamron's SP-series of lenses.
