Tamron SP 35mm f/1.4 Di USD Marks 40th Anniversary of SP Lenses


Commack, NY—Tamron launched a fixed-focal lens, the Tamron SP 35mm f/1.4 Di USD (model F045), for full-frame DSLR cameras. The lens, announced as under development in February, reached Tamron USA authorized retailers on June 26, 2019 in the Nikon F mount and July 25 in the Canon EF mount.

Tamron’s SP (Superior Performance) lens series was born in 1979. It is based on the concept of “delivering lenses for taking the perfect picture for those who love photography.” Moreover, this year marks the 40th anniversary of the series. In celebration, Tamron created the model F045.

The new lens is the distillation of the company’s accumulated lens-making expertise and craftsmanship. This orthodox fixed-focal lens, the most basic of all interchangeable lenses, embodies all of the optical technology and manufacturing know-how Tamron has developed to date.

“The model F045’s unprecedented high-resolution image quality and beautiful, appealing background bokeh lets photographers capture any scene down to the finest details. The external lens barrel was developed through the tireless pursuit of operability and durability, focusing constantly on the needs of photographers,” the company announced.

In addition, the lens employs a large f/1.4 aperture and high-speed, high-precision autofocus. It also offers features for increased convenience. As a result, it is an everyday lens for nearly every photographic genre, including photojournalism, landscape, sports, street life, weddings as well as family snapshots.

“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. “Moreover, we deployed existing skills, like our highly regarded know-how for producing bokeh. And we combined them with new innovations like BBAR-G2 (broad-band antireflection generation 2) coating for antireflection performance.”

Tech Specs

The optical construction (14 elements in 10 groups) features an arrangement of special glass materials. They include four LD (low dispersion) as well as three GM (glass molded aspherical) lens elements. This combination eliminates the effects of chromatic aberrations that often occur with high-speed lenses; it also reduces other optical aberrations.

Even at its maximum aperture of f/1.4, Tamron says the lens achieves high resolution from the center of the frame to the edges, providing aberration correction to maintain fidelity of point shapes. This optical performance extends to the quality of defocused bokeh areas. Photographers can capture images that sculpt their subjects against large and appealing background bokeh.

Furthermore, to combat ghosting and flare, Tamron developed BBAR-G2 coating. This new technology exceeds the performance of the original BBAR coating. In addition to minimizing ghosting and flare, BBAR-G2 enables clear images with dramatic contrast.

In addition, the lens’s AF drive is equipped with Tamron’s USD (ultrasonic silent drive) for high-speed, precision, quiet operation. Moreover, thanks to a dynamic rolling-cam mechanism developed specifically for this lens, Tamron succeeded in minimizing the drive load placed on the focus lens component. This ensures stable AF operating performance and improves reliability even under harsh shooting conditions, such as high and low temperature extremes.

The lens is also equipped with a full-time manual focus override system. As a result, photographers can quickly make fine adjustments to the point of focus, even in AF mode.

Another improvement is the front surface of the lens element has a fluorine coating based on a newly developed compound with high water- and oil-repellent properties. The lens surface is easier to wipe clean and less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

Additional Features

Also, for moisture resistance, seals are located at the lens mount area and other critical locations. This feature affords an additional layer of protection when shooting outdoors under adverse weather conditions. And the included lens hood has a locking mechanism; this prevents it from unintentionally shifting position or coming off at the wrong time. Other features include: a 9-blade circular diaphragm; a minimum focus distance of 11.8 inches; a luminous gold brand ring; an ergonomic switch box shape; a legible distance-scale window; and a metal mount.

Tamron TAP-in Console

In addition, the SP lens is compatible with the Tamron TAP-in console. The optional accessory provides a USB connection to a computer. It enables users to update firmware as well as customize features, like fine adjustments to the AF.

The Tamron SP 35mm f/1.4 Di USD (model F045) for full-frame DSLR cameras retails for $899.
