Tamron has announced the 35-150mm F2.8-4 Di VC OSD lens for Canon EF and Nikon F mounts.
The lens, which Tamron says is a ‘dedicated portrait lens,’ is constructed of 19 elements in 14 groups including three Low Dispersion elements (LD), three hybrid aspherical elements and a features Tamron’s Broad-Band Anti-Reflection (BBAR) coating throughout the lens to reduce ghosting and flares. Its maximum aperture range is F2.8 through F4 while its minimum aperture range is F16 through F22, depending on what focal length the lens is set to, and it features a nine blade aperture diaphragm.
Autofocus on the lens is powered by Tamron’s Optimized Silent Drive (OSD) DC motor and the image stabilization is done with Tamron’s Vibration Compensation (VC) technology, which is CIPA-rated for up to five additional stops of stability.
The lens features a minimum focusing distance of 45cm (17.7in) across the entire zoom range, a 77mm filter thread and a fluorine coating on the front lens element to protect against water and oil. The lens measures in at 124.4mm (4.9in) long and weighs 790g (27.9oz) for the Nikon F mount version, and measures 126.8mm (5in) long and 796g (28.1oz) for the Canon EF version. Tamron’s TAP-in ConsoleTM can be used with this lens to update the lens’ firmware and make fine adjustments to the autofocus and vibration compensation motors inside.
The Tamron 35-150mm F2.8-4 is currently available for pre-order at B&H for $ 799 (Canon EF, Nikon F).
