Art in subjective. Performance isn't.
SP 35mm F/1.4 Di USD
Bringing it all together for that single shot
For the first time, a dedicated portrait lens that allows you to zoom through various composition options as the creative ideas zoom through your head. “We want to deliver a perfect image to people who love photography.” That’s our obsessive goal for all Tamron lenses. This goal forms the basis of our concept for the SP 35mm F/1.4 Di USD (Model F045). The exceptional image quality of this fast fixed focal lens makes it worthy of being the lens that marks the milestone 40th anniversary of the SP (Superior Performance) Series. Uncompromising resolution at wide-open aperture combines 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, our new and exclusive Dynamic Rolling-cam mechanism enables the heavy F/1.4 focusing unit to move with incredible accuracy at high-speed and deliver the best AF performance in every shooting situation. Truly, the Model F045 is the distillation of all of the optical technologies and manufacturing knowhow that Tamron has developed.
Optical performance that defines the ultimate Tamron lens ever made
We endeavored to achieve ultra-high quality where every shape is captured with perfect fidelity. So we meticulously eradicated any optical aberrations that could reduce image quality. In particular, we have eliminated 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 Model F045 produces a 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 a color fringe. So we created a countermeasure to thoroughly overcome these deficiencies and produce a bokeh that blends in beautifully without introducing aberrant color in front of or behind the focal plane.
Newly developed 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 (Broad-Band Anti-Reflection) 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 all-new Dynamic Rolling-cam 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.
Compatible with TAMRON TAP-in ConsoleTM, an optional accessory
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.
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
