Breathtaking sharpness - velvety, soft bokeh - un compromised performance. The culmination of Tamron's relentless obsession to deliver the ultimate image quality. Capture your vision. Pursue your passion. Unmask your potential.FEATURES:This lens completely unlocks the pleasure of photography - "We want to deliver a perfect image to people who love photography." That’s Tamron's obsessive goal for all Tamron lenses. This goal forms the basis of Tamron's 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, Tamron's 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.
