The Sigma Macro 150mm F2.8 EX DG HSM boasts Optical Stablization (OS) which is critical to equipment sporting this focal range & is now splash-proof. Offering the latest optical design technology this lens remains a large aperture medium macro lens ideal for shooting the smaller things in our world that exists virtually unseen. A macro lens is one which will focus on a subject close enough to render it "life-size" on the image plane in your camera. It also has a "flat field" front lens element so that it can shoot images of flat objects such as artwork or postage stamps & be tack sharp all the way across the image. With HSM (Hyper-Sonic Motor) a quiet & high-speed auto focus is ensured. It provides extremely high optical performance from infinity to 1:1 macro. Three SLD (Special Low Dispersion) glass elements provide optimum color correction & sharpness throughout the entire range & super multi-layer coating reduces flare & ghosting. It has superior peripheral brightness & provides sharp & high contrast images even at maximum apertures. The OS offers the use of shutter speeds Approx. 4 stops slower than would otherwise be possible. It is also compatible with Sigma APO Tele converters. Ideally suited for taking pictures of insects or other small creatures, but it is also the perfect focal length for facial portraits rendering the best perspective of the human face. This greater distance also allows the photographer more flexibility in lighting the subject with natural light reflectors. So dont miss the tiny insects, flowers of the world or the details in a stamp or coin collection or a piece of embroidery all of which are seldom noticed but offer a fascinating world if you look closely enough. Capture them with the Sigma Macro 150mm F2.8 EX DG OS HSM APO Macro. ...

Sigma 20mm f 1.8 EX DG Aspherical RF is one of several EX Series lenses. It is the first 20mm Super wide-angle lens in the world with a large aperture of F1.8 & angle of view 94.5 degree. It has Macro focusing capability with a minimum focusing distance of 20cm/7.9inches (reproduction ratio 1: 4). The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus image. It incorporates an aspherical lens element in the front as well as rear lens groups, to minimize distortion, spherical aberration & astigmatism. The lens has non-vignetting optical construction, in order to obtain adequate peripheral brightness with open aperture. This is especially desirable for digital cameras. The lens incorporates a rear focus system eliminating front lens rotation, thus allowing the use of a Perfect Hood & easy use of polarizing filters. The lens also incorporates dual-focus mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The lens materials used in this lens are lead & arsenic free ecological glass. ...

Sigmas splash-proof feature is also included preventing dust & precipitation from getting inside the lens. One SLD & two FLD glass elements provides maximum correction of chromatic aberrations. The super multi-layer coating reduces flare & ghosting, & the lens design incorporates an inner focusing & inner zooming system to ensure sharp images throughout the entire zoom range. enhanced optical performance provides excellent correction of sagittal coma flare & ensures ultra-high resolution, comparable to a fixed focal length lens. The HSM (Hyper Sonic Motor) ensures quiet & high speed AF, while allowing full-time manual focus override. A truly unique product which is a rarity in the photo industry, this lens is the only lens of its kind on the market; a professional zoom lens that also features a fast aperture. Most professionals own the standard 300mm 2.8, but they also have to carry a shorter zoom lens for those times when the subjects move closer. That means fumbling around switching lenses or carrying a second camera body. The amazing Sigma zoom lens let you instantly determine the picture composition you want without having to change your vantage point. Imagine photographing courtside at a college basketball game & having the versatility to zoom in on a players face or hand & then instantly zoom back to capture the entire player making his shot. ...

To achieve an F2.8 aperture at all focal lengths, it employs three aspherical lens to provide optimum aberration compensation. Two Special Low Dispersion (SLD) glass elements are provided for color aberration compensation, to assure high image quality. ...

Sigmas EX DG filters benefit from multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens & filter elements & re-enter the image sensor, creating a ghost image. In addition to this, an optimum, neutral color balance is ensured, increasing the white balance accuracy of the digital camera. ...
