![]() ![]() ![]() The optical construction includes a generous arrangement of special glasses, four LD (Low Dispersion) lens elements and three GM (Glass Molded Aspherical) lens elements. This is accomplished by deploying 14 elements in 10 groups, a dense arrangement for a fixed focal lens. 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. So we meticulously eradicated any optical aberrations that could reduce image quality. We endeavored to achieve ultra-high quality where every shape is captured with perfect fidelity. Optical performance that defines the ultimate Tamron lens ever made Truly, the Model F045 is the distillation of all of the optical technologies and manufacturing knowhow that Tamron has developed. ![]() 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. Ghosting and flare are suppressed to the utmost degree by the newly-developed BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating. Uncompromising resolution at wide-open aperture combines with a velvety bokeh defocus blur that gently blends away from the ultra-sharp focus area. 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 (Super Performance) Series. This goal forms the basis of our concept for the SP 35mm F/1.4 Di USD (Model F045). “We want to deliver a perfect image to people who love photography.” That’s our obsessive goal for all Tamron lenses. Bringing it all together for that single shot This lens completely unlocks the pleasure of photography ![]()
