The Tamrom SP 85mm F/1.8 Di VC USD Lens is the first 85f/1.8 lens with vibration control – making it possible to take sharp photos in dimmer light than previously thought possible. The lens uses Low Dispersion (LD) and Extra Low Dispersion (XLD) to minimize color fringing and achieve sharp and clear image quality with high-fidelity color. Since beautiful things also happen in the rain the lens features moisture resistant construction to prevent the intrusion of moisture and dust. A highly durable Fluorine coating has been applied to the front element to help shed water and grime.
Superior resolving power and attractive bokehExperienced optical design technique combined with LD and XLD lens elements have virtually eliminated on-axis and lateral chromatic aberrations that might otherwise appear as color fringing. In addition, by thoroughly reducing chromatic aberrations (distortion of off-axis point source) and astigmatism, subjects that appear as a distinct point source will be captured as a distinct point source even at the edges and corners of the frame. Furthermore, optical simulations were thoroughly conducted, and the 85mm achieves natural bokeh— that dreamy, semi-focus blur that separates the portrait subject from the background with a snap.
Fluorine Coating and Moisture-Resistant ConstructionFluorine Coating technology developed for use in industrial optics applications has been adapted to photographic lenses. The water and oil repellant coating applied on the front element surface allows safe and easy removal of fingerprints, dirt and smudges. The coating also provides an enhanced level of durability, and will sustain its effectiveness for years. In addition, seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops and provide Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.
Sophisticated eBAND and BBAR coatings plus Advanced Anti-Reflection TechnologiesTwo highly developed lens coating technologies, eBAND (Extended Bandwidth & Angular-Dependency) which uses nanotechnology, and BBAR (Broad-Band Anti-Reflection), combine to increase light transmission and to reduce flare and ghosting to imperceptible levels. Additional techniques are employed to prevent reflections inside the lens barrel so that the 85mm lens delivers high contrast, sharp and clear images worthy of a fixed focal lens. This lens clearly captures detailed tones even in the shadows.
USD AF Motor optimized for fast and accurate focusingFast, quiet AF is achieved by employing a USD (Ultrasonic Silent Drive) ring-type ultrasonic motor which enables remarkably precise focusing drive with high torque and responsiveness. Thanks to the absence of reduction gears in USD, there is no backlash and no unnecessary back-and-forth movement. The control software program for the USD actuator has been revised to provide substantially improved focusing speed and accuracy when using AF. In addition, Full-time Manual Focus override is available at any point during the autofocus operation for deliberately shifting focus without switching the AF-MF. Whether overriding the autofocus or focusing completely manually, the focusing ring turns smoothly and evenly.
Compatibility with TAMRON TAP-in ConsoleAlways as new as tomorrow: You can update firmware, customize autofocus positions and adjust the mechanical setup and preferences of the 85mm lens by simply attaching it to the TAMRON TAP-in Console and connecting it via USB to a personal computer.
