Tamron SP 35mm f/1.4 Di USD Lens
(for Nikon Cameras)
Bringing it all together for that single shot.
The Tamron SP 35mm f/1.4 Di USD Lens offers uncompromising resolution at wide-open aperture combined with a velvety bokeh defocus blur that gently blends away from the ultra-sharp focus area. Ghosting and flare are suppressed to the utmost degree by the newly-developed BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating.
Additionally, Tamron's exclusive Dynamic Rolling-cam mechanism enables the heavy f/1.4 maximum aperture focusing unit to move with incredible accuracy at high-speed and deliver the best AF performance in every shooting situation.
Optical performance that defines the ultimate Tamron lens ever made:
Endeavoring to achieve ultra-high quality where every shape is captured with perfect fidelity, any optical aberrations that could reduce image quality were eradicated. In particular, eliminating the on-axis chromatic aberrations that plague fast-aperture lenses, and the sagittal coma flares that reduce peripheral image quality. This is accomplished by deploying 14 elements in 10 groups, a dense arrangement for a fixed focal lens. The optical construction includes a generous arrangement of special glasses, four LD (Low Dispersion) lens elements and three GM (Glass Molded Aspherical) lens elements.
Leveraging Tamron's experience creating beautiful bokeh:
The SP 35mm F/1.4 Di USD produces genuinely beautiful bokeh defocus blur both in front of and behind the plane of focus, a characteristic shared with Tamron's legendary 90mm F/2.8 macro lens. The major difference is the fast F/1.4 aperture. Normally, as the lens aperture opens subtle on-axis chromatic aberration appears as color fringe. So a countermeasure was created to thoroughly overcome these deficiencies and produce bokeh that blends in beautifully without introducing aberrant color in front of or behind the focal plane.
BBAR-G2 Coating delivers stunning clarity and contrast:
Tamron has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR Coating. The coating corrects for ghosting and flare to an unprecedented extent, and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.
Exceptionally reliable, fast and accurate AF that unleashes creativity in every situation:
The AF drive is equipped with Tamron's proprietary USD (Ultrasonic Silent Drive) motor. Additionally, Tamron's Dynamic Rolling-cam mechanism mechanism operates the heavy focusing unit of the large F/1.4 aperture with high speed and accuracy. This breakthrough ensures stable AF performance and improves reliability even under the harsh shooting conditions of professional use, including high and low temperature extremes. This exceptional lens is also equipped with a Full-Time Manual Focus override system so photographers can instantly make fine adjustments to the point of focus, even in the AF mode.
Highly durable Fluorine Coating for improved durability:
The durability of the front element coating is greatly improved with the development of Fluorine Coating. With the fluorine compound that has excellent water- and oil-repellent properties, the lens surface is much easier to wipe clean and less vulnerable to damaging effects of dirt, dust, moisture, and fingerprints, enabling your important lens to be continually protected on a long-time basis.
Moisture-Resistant Construction protects your lens:
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
Locking mechanism built into the lens hood:
The lens hood is equipped with a locking mechanism, which prevents detachment due to unintentional contact during use.
Electromagnetic diaphragm system compatible with Nikon cameras:
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is employed in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.
Circular Aperture to Produce a Smooth-Edged Bokeh:
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background light spots and avoids rugged aperture geometry.
Compatible with the TAMRON TAP-in Console:
The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens's firmware as well as customize features including fine adjustments to the AF.
