Make your pictures better than ever, with a lens that offers both long telephoto and macro capability
Compactness, light weight and affordability are brought together in the Tamron 70-300mm F/4-5.6 Di, giving emerging photographers an alternative to the highly lauded SP 70-300mm F/4-5.6 Di VC USD. Picture takers eager to bring distant sports or wildlife subjects closer, as well as bringing tiny, close range subjects into clear focus will appreciate the standout macro function, available at focal lengths between 180 and 300mm. Capable of a maximum magnification ratio of 1:2 (one half life-size) close-up detail fills the viewfinder. Also, because the macro function is available at the lens' longer telephoto settings, an extended subject-to-lens working distance is maintained.
Recommended for APS-C photographers who...
- Long for the ability to pull small and/or distant subjects further into view.
- Enjoy the world of extreme close-up picture taking.
- Appreciate the versatility of combining a telephoto zoom and 1:2 macro functionality in one lens.
- Demand optical performance once reserved for much costlier lenses.
A compact, lightweight telephoto zoom featuring high image quality for both digital SLRs and 35mm film cameras
Tamron has redesigned its lightweight, compact AF70-300mm F/4-5.6 telephoto zoom lens that already had a great reputation for being easy to use. The result? A Di series lens that now goes equally well with digital SLRs and 35mm film cameras. This flexible lens delivers digital photography up to a super-telephoto 465mm equivalent.* Use itto zoom in ultra close, even for action shots of moving subjects such as sports participants or children running and playing. * When converted to 35mm film form
Optical design meets digital camera performance characteristics
Tamron's "Internal Surface Coatings"* and new multiple-layer coating technology on ordinary elements reduce ghosting and flare that happens due to reflections that can occur when light enters the lens as well as reflections caused by the imager itself. The strictest quality control standards were also applied to increase resolution performance and prevent flare due to aberrations, resulting in a telephoto zoom lens ideal for photography with digital SLR cameras. This is one lens you can use with confidence. * Multi-layer coatings on cemented surfaces of plural element
True macro photography with amagnification ratio of 1:2
Just flip the macro switch between the focal lengths of 180mm and 300mm, and you can enjoy true macro photography with a telephoto effect giving a maximum magnification ratio of 1:2. The minimum focus distance is 1.5m from the subject in normal shooting ranges (Max. Mag. Ratio 1:3.9), but when you flip the macro switch, you can get as close as 95cm. And an added bonus the nine blade circular diaphragm provides beautiful soft focus imagery for a professional result. Showcase all your photographic talent with close-up shots of small flowers and insects in parks or in the wild, or any other beautiful small object you discover.
Tamron Di lenses designed for digital SLR cameras.
Digitally Integrated Lenses for Top Imaging Performance. Di (Digitally Integrated Design) is a Tamron designation that applies to lenses that have been optimized for digital capture using advanced multi-coating techniques and optical designs that assure excellent image quality across the entire picture field. Because of these characteristics, Di lenses provide outstanding performance on cameras with full-frame and APS-C format sensors as well as on 35mm film.
Low Dispersion (LD) Glass for Greater Lens Sharpness
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)
