Designed for full-frame DSLR cameras
The lens features a telephoto focal length of 85mm on 35mm/full frame Canon DSLR cameras, or 136mm on cropped APS-C sensor cameras.
The SP 85mm F/1.8 is the world’s first lens with a fixed focal length of 85mm and a fast aperture of F/1.8 that’s equipped with the VC system. Camera movement—often too minute to be perceptible to the photographer—is the leading cause of unpleasant photographs. In addition, newer DSLR cameras with higher pixel densities are more susceptible to subtle camera shake.
This technology makes it possible to take photographs handheld in dim light and to make optimal use of slower shutter speeds and increased depth-of-field without extreme increase of the camera’s sensor sensitivity (ISO equivalent). This is especially important in portraiture because lighting is often low and the photographer needs the spontaneity of not using a tripod or disruptive flash units.
Sharper Images. Better Bokeh .
To meet and surpass the needs of modern cameras with high resolution and high pixel densities, the SP 85mm F/1.8 employs LD and XLD low dispersion glass elements to correct critical aberrations. Superb optical design makes color fringing inconspicuous, achieving sharp and clear image quality and enabling outstanding performance at any illumination level. eBAND and BBAR coatings work in concert with wide-ranging anti-reflection techniques to increase light transmission, reduce flare and ghosting, and to prevent reflections inside the lens barrel.
The SP 85mm F/1.8 is designed to provide tack-sharpness of the subject for stunning clarity and flawless image quality. At the same time, Tamron’s design philosophy embraces the notion that photographers—particularly portrait photographers—use background blur, bokeh , as a creative element to concentrate emphasis on the subject. Through numerous simulations conducted for wide-ranging blur effects, such as a gentle, melting transition from the focused to the out-of-focus areas, Tamron has created a soft and natural blur effect that achieves perfect harmony with the inescapable sharpness.
Resists Moisture, Repels Smudges
Moisture-Resistant Construction, including special seals at areas of possible ingress, provides added protection. A highly durable Fluorine Coating, applied to the surface of the top element, prevents condensation and repels smudges, grime and fingerprints.
XLD (Extra Low Dispersion) Glass
A special glass with an extremely low colour dispersion index for the greatest level of sharpness and compensation of chromatic aberration.
LD (Low Dispersion)
Lens element for greater image sharpness and the correction of chromatic aberration.
