The Tamron SP 24-70mm F/2.8 Di USD Lens is a high-quality, highly functional, high-speed standard zoom lens covering the 24-70mm focal range. It includes USD (Ultrasonic Silent Drive) motor, enabling speedy, silent autofocusing.
This SP (Super Performance) series lens makes full use of specialised glass elements in its lens layout, designed with top priority on image quality, including three LD (Low Dispersion) elements and two XR (Extra Refractive Index) glasses. Tamron has minimised all types of chromatic aberration in the A007, making it a lens at the top of its class whether you use it on a digital APS-C, full-frame, or 35mm SLR camera.
Advanced optical technology
Specialised high-grade glass in the three LD elements, three Glass Molded Aspherical Lenses, one Hybrid Aspherical Lens and two XR (Extra Refractive Index) elements all contribute to the top-of-class image quality expected of a high-grade Tamron SP lens.
The rounded outline diaphragm of the lens is retained even when stopped down to f/5.6. Blur highlights in a photo reflect the shape of the aperture, and they are a much more prominent feature at wider apertures. In this high-speed lens, this important optical design element results in more attractive, natural-looking images.
USD (Ultrasonic Silent Drive)
Tamron's proprietary USD (Ultrasonic Silent Drive) powers a speedy autofocus system. Major improvements in autofocus response and tracking ability over standard DC motors enable instantaneous focusing and spontaneous shooting of rapidly moving subjects. This extremely quiet motor is ideal for photography of events, weddings, theatre or musical performances, as well as crucial moments on the golf course – any situation where autofocus noise is obtrusive.
Direct Manual Focus
The USD motor is complemented by Direct Manual Focus to enable manual fine-tuning after autofocusing if and when necessary. No need to engage a switch – just gently rotate the focus ring.
Moisture resistance adds protection
Moisture-resistant body construction helps prevent water from penetrating the lens, making it well suited ideal for travel and shooting outdoors.
Flower-shaped hood is supplied with the lens to shield stray light
Included as a standard accessory, the flower-shaped hood matches the rectangular shape of the image sensor to most effectively block the interference of superfluous light rays entering from outside the borders of the image area, helping to ensure sharp, clear, flare-free images with crisp detail in the shadow areas.
Form and texture that embodies the high-performance, high-precision qualities of the SP series
This lens features the gold metal ring that symbolises the SP series, and other design elements that boost its looks.
