Las Vegas, NV—Shiro Ajisaka, president and CEO of Tamron Co., Ltd., announced the development of two lenses for full-frame DSLRs: the 35–150mm f/2.8–4 Di VC OSD (model A043) zoom lens and the SP 35mm f/1.4 Di USD (model F045) fixed-focal lens. Moreover, the company is developing a high-speed ultrawide-angle zoom lens for Sony E-mount full-frame mirrorless cameras: the 17–28mm f/2.8 Di III RXD (model A046).
Tamron displayed the new lenses at the CP+ 2019 camera and photo-imaging show last month as well as at the 2019 WPPI show. The lenses will ship in the middle of 2019.
Lenses for Full-Frame DSLRS
Tamron 35–150mm f/2.8–4 Di VC OSD
This compact portrait zoom lens offers fast handling and easy transport. It features a zoom that extends from 35mm to 150mm, incorporating the 85mm focal length for portrait shooting. In addition, it provides a fast f/2.8 aperture at the wide-angle end while maintaining a bright f/4 at the telephoto end. 
Also, for close-focusing, the MOD (minimum object distance) is 17.7 inches across the entire zoom range. The lens employs LD (low dispersion) glass elements and aspherical lenses to quash optical aberrations. Furthermore, model A043 incorporates Tamron’s dual MPU (micro-processing unit) system to help ensure AF performance and vibration compensation.
Tamron SP 35mm f/1.4 Di USD
This year marks the 40th anniversary of Tamron’s SP lens series. In celebration, Tamron developed model F045. It is the distillation of Tamron’s accumulated lens-making expertise and craftsmanship. This orthodox fixed-focal lens, considered the most basic of all interchangeable lenses, is the embodiment of all Tamron’s optical technology and manufacturing know-how.
“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 tireless pursuit of operability and durability, focusing constantly on the needs of photographers,” the company announced.
The lens is equipped with a fast f/1.4 aperture as well as high-speed, high-precision AF. It also offers various other features for increased convenience, making it a solution for everyday picture taking. It is suited for nearly every photographic genre, including photojournalism, landscape, sports, street life, weddings as well as family snapshots.
Lens for Full-Frame Mirrorless E-Mount Cameras
Tamron 17–28mm f/2.8 Di III RXD
Model A046 achieves a small diameter for a high-speed ultrawide-angle zoom lens, as witnessed by its modest 67mm filter size. Moreover, its light weight and compact size provide balance when used with a Sony full-frame E-mount mirrorless camera. The lens has a fast f/2.8 aperture throughout the entire zoom range. And it delivers high-resolution and contrast edge to edge.
The combination of its ultrawide-angle focal length, fast constant f/2.8 aperture and 7.5-inch MOD at the wide-angle end makes it an option for a range of creative photography. In addition, an RXD (Rapid eXtra-silent stepping drive) stepping motor unit powers its AF drive system. The system enables the lens to deliver high-speed, high-precision and quiet operation. As a result, it is an option for shooting video as well as still photographs.
Tamron will announce pricing for the three lenses at a later date.
