As a super performance (SP) lens,the Tamron SP AF 180mm f3.5 Di LD IF Macro Lens for Canon EOS belongs to the best macro lenses in the world. It has very good resolution ability, strongly decreased light fall-off up to the edges, minimised chromatic aberration and excellent stray light behaviour making this lens the first choice for digital APS-C and full frame cameras. This lens was constructed for macro functionality; however, it also makes an excellent figure with medium-tele shots and shines with its extremely sharp, high contrast and high brilliant results. This lens stands in the tradition of the legendary 90 mm 1:1 macro.
Apart from the long focal length the lens also offers a big working distance, which is often required for capturing images of small creatures. Furthermore, the so-called FEC (filter Effect Control) allows the rotation of a polarisation filter while the hood is attached.
SP ( Super Performance) – This lens belongs to the Super performance ( SP) class of Tamron lenses distinguished by ultra high optical and mechanical quality.
The designation “Di” (Digitally Integrated Design) marks a generation of lenses, which have been specially adapted to the higher requirements of digital SLR cameras (APS-C and full frame).
Tamron SP AF 180mm f3.5 Di LD IF Macro Lens for Canon EOS Features and Functions:
Delivering leading-edge image quality
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.
This lens offers a 1:1 magnification ratio to enable you to focus in on even the smallest details. It is thus ideal for close-up photos of animals and plants, as well as for still life photography. As a result of the excellent image quality and high luminosity, the macro lens has also proved a popular choice for portrait photography.
