The Tamron 70-300mm f4-5.6 SP Di USD Lens offers unparalleled optical performance in a fast and steady telephoto zoom. Its advanced design features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element to help prevent chromatic aberration and provide sharp contrast.
The 70-300mm f4-5.6 SP Di USD is the first Tamron lens to be equipped with a USD (Ultrasonic Silent Drive), Tamron's very own ultrasonic auto-focus drive mechanism for faster focusing, making it a perfect telephoto zoom choice for photographing sports, wildlife, or other fast-moving subjects. This combination of technology and quality optics makes the Tamron 70-300mm f4-5.6 SP Di USD Lens a premium telephoto zoom lens.
The optical design of this lens uses a high-performance XLD (Extra Low Dispersion) element, which is manufactured out of a special glass with an extremely low refractive index. The refractive index describes the ability of the lens to split a light beam into its spectral colours. The dispersive properties are even lower than standard LD lenses and are at a level similar to fluorite. The XLD lens in combination with the LD element delivers the highest contrast and brilliance. This effectively prevents the problem of chromatic aberration in telephoto photography and delivers a high level of sharpness even in the peripheral regions. The result is a lens that effectively compensates for axial chromatic aberration and magnification aberration throughout the entire zoom range and guarantees the highest resolution and brilliance for your pictures.
Only two letters - but what an impact they have on the results. SP stands for Super Performance and represents the high-performance lens class from Tamron. Our engineers were given a free hand in the design of these lenses and left no stone unturned to produce the optimal performance characteristics in each case. Take your camera to new frontiers - and pave the way for Super Performance.
USD (Ultrasonic Silent Drive) Motor is the power for a fast and quiet autofocus drive that works in harmony with continuous manual focus mechanism.
One special XLD (Extra Low Dispersion) glass and four LD (Low Dispersion) elements minimize chromatic aberrations.
The extension length of the lens does not change during focusing and the close focusing distance is significantly reduced across the entire focusing range.
