With a minimum focusing distance of 45cm and a maximum magnification ratio of 1:4.6, this lens is excellent for close-up photography.Superior image qualityThis is a lens that represents the concept of our “Art” line, and it meets the highest standard of our quality test. For those standard lenses with a high zoom ratio, they tend to show astigmatic aberration, field curvature, distortions and color aberration. In order to compensate for these, various types of high-performance lenses, such as FLD, SLD and glass-molded aspheric lenses including double-sided aspheric lens, have been included into the optical system. In addition, it suppresses chromatic aberration very effectively at telephoto-end, and achieves superior image quality throughout the zoom range. This lens overcomes low peripheral brightness that is common for those lenses with similar specifications. Also, the wide filter size 82mm is contributing for superior optical performance.Optical StabilizerThis lens incorporates an OS system which offers superior stabilization, making it possible to compensate for camera shake even in macro range photography where a small blur can be easily identified.Designed to minimize flare and ghostingFlare and ghosting were thoroughly measured and monitored from an early stage in the lenses development to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. Attaching the matched petal type hood, which is supplied, will provide extra protection from flare and ghosting.Hyper Sonic MotorThe HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. It also enables full-time manual focusing capability which allows sensible focus adjustment by simply rotating the focus ring.

This top-of-the range EX-Series Telephoto Zoom lens has been digitally optimised and will work equally well on digital or film SLR cameras. It uses state of the art glass technology, along with optical image stabilisation and ultra-fast and quiet focusing components.Optical StabilisationThe optical image stabiliser on this 120-300mm lens gives the equivalent of 4 stops faster shutter speeds, making hand held telephoto shooting possible. It also has normal and panning modes, so that you can still get effective stabilisation while following for example a motor race without jerky actions.Superb OpticsThis lens includes one SLD (Super Low Dispersion) and two FLD (Fluorite Low Dispersion) lenses for excellent correction of chromatic aberration and for image quality comparable to a prime lens. Sagittal coma flare is also greatly reduced. Finally, the Super Multi-Layer Coating helps your images retain their vitality and contrast levels by cutting out internal flare and ghosting effects.Inner Focus and Inner ZoomingYou can focus and zoom with no rotation or change to the length of the lens, allowing for much easier handling, especially when using filters. The Hyper Sonic Motor with Full Time Manual Focus override also means that you get ultra fast, ultra quiet focusing when required and instant manual override when you need to take control.Additional FeaturesConstant f/2.8 ApertureRounded 9-Blade ApertureCompatible with Sigma APO TeleconvertersIncludes Removable Tripod Collar
