In celebration of the 40th Anniversary of Tamron's SP Series Lenses, the company has announced the upcoming launch of its new SP 35mm F/1.4 Di USD (Model F045). The lens will be available for the Nikon F mount on June 26 and the Canon EF mount on July 25 for an MSRP of $899.
"To commemorate the 40th Anniversary of Tamron's renowned SP series lenses that are designed and constructed to deliver the highest levels of performance, we drew upon our accumulated expertise and technologies to create the 'ultimate lens' -- the Model F045," said the person responsible for product planning. "Our goal was to achieve high resolution, fidelity of point light source and beautiful bokeh," he continued. "We deployed existing skills, like our highly regarded knowhow for producing bokeh, and combined them with new innovations like BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating for anti-reflection performance. Today we announce with sincere pride that the Model F045 embodies Tamron's philosophy for manufacturing and is the finest lens in Tamron's history."
The SP 35mm F/1.4 Di USD is a fixed focal lens geared toward a variety of photography applications, including photojournalism, landscape, sports, street life, wedding groups, and family pictures. The unit's optical construction consists of 14 elements in 10 groups with four LD (Low Dispersion) and three GM (Glass Molded Aspherical) lens elements, helping to reduce various chromatic and optical aberrations. In addition, the device incorporates a special BBAR-G2 Coating to reduce ghosting and flare, and a Fluorine Coating to help protect against dirt, dust, moisture, and fingerprints.
Meanwhile, when it comes to AF performance, the lens features Tamron's proprietary USD (Ultrasonic Silent Drive) for high speed, precise, and quiet operation. Likewise, the system also uses a newly developed Dynamic Rolling-cam mechanism to minimize the drive load placed on the focus lens component, and also offers a Full-Time Manual Focus override.
