Tamron SP 85mm f/1.8 Di USD Lens for Sony A

SP 85mm F/1.8 Di VC USD�- The world's first fast-aperture telephoto lens with VC (Vibration Compensation)�Tamron's acclaimed VC makes it possible to take handheld photographs in dim light or at night. The 85mm SP lens uses LD (Low Dispersion) and XLD (Extra Low Dispersion) glass elements in the optical design to minimize color fringing and to achieve sharp and clear image quality with high-fidelity color. It also achieves attractive bokeh that draws attention to the image foreground subject. In addition, Moisture-Resistant Construction has been added to prevent intrusion of moisture, and a highly durable Fluorine Coating has been applied to the top element surface to prevent condensation and repel smudge-causing substances.�The world's first 85mm fast-aperture lens with image stabilization�Tamron's VC image stabilization system enables handheld use in dim light without flash. Camera movement - often too minute to be perceptible to the photographer - is the leading cause of unpleasant photographs. In addition, newer DSLR cameras with higher resolution and higher pixel densities are even more susceptible to subtle camera shake. The VC System, Tamron's time-proven Vibration Compensation, keeps the sharpness at hand, even in moody, dim light when shutter speeds tend to be longer.�Superior resolving power and attractive bokeh�Experienced 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 comatic 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 Construction�Fluorine 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 Technologies�Two 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 actuator maximized for fast and accurate focusing�Fast, 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 Console�Always 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. (sold separately)�Compatibility with Adobe and Silkypix software�Supplied with SILKYPIX Developer Studio 4.0, advanced editing software that features correction menus for various aberrations (lateral color, distortion, relative illumination) based on the optical design data of this specific lens. In addition, lens profile information has been supplied to Adobe Systems, Inc. to facilitate selecting the precise lens data required for more sophisticated adjustments in RAW processing when using Adobe Photoshop and Lightroom. Shooting RAW image files enables creation of more stringent and high-fidelity image quality.�Design Concept�The
