Sigma AF 105mm F2.8 DG OS Macro Lenses for Canon mount
Super compact and lightweight, large aperture telephoto lens with life-size macro capability. Successor to the APO MACRO 150mm F2.8 EX DG HSM, introduced to market in October 2004, this new OS design offers the latest optical technology. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.
Sigma 105mm f2.8 Macro EX DG OS HSM - Canon Fit
The Sigma 105mm f2.8 Macro EX DG OS HSM is a high performance, large aperture medium telephoto macro lens that comes with an Optical Stabiliser (OS). The lens helps users to maintain an appropriate distance from the subject of their photos while still being able to take close-up images. It features SLD glass elements that provide fantastic control of aberration as well as a floating inner focus system that allows for high rendering throughout the focusing range. It is a true macro lens with a 1:1 magnification that produces stunning images.

Sigma 105mm F2.8 Macro EX DG OS Lens for Canon
High performance, large aperture medium telephoto Macro Lens with OS (Optical Stabilizer). SLD glass provides good control of aberration and the floating inner focus system ensures high rendering throughout the focusing range. By using Sigma's APO Tele Converter, it is possible to take photos at greater than 1:1 magnification. HSM ensures a quiet and high speed AF as well as full-time manual focus override. This Lens has a rounded 9 blades diaphragm which creates an attractive blur to the out of focus areas. Large aperture medium telephoto Macro Lens This medium telephoto Macro Lens allows you to maintain an appropriate distance from subjects while still getting close up photos. Since the working distance at its closest focusing position is 142mm, shadows of the Lens and camera will not affect photography making it suitable for taking photos of subjects, such as flowers, under natural lighting conditions. In comparison to the Sigma 50mm and 70mm Macro Lenses, the main subjects can be defined with perfectly smooth and blurred backgrounds. High rendering performance The Lens power layout produces excellent optical performance. High refractive index SLD (Special Low Dispersion) glass corrects chromatic aberration, spherical aberration and field curvature. It ensures high rendering performance at all shooting distances. The Super Multi-Layer Coating reduces flare and ghosting, maintaining quality images with high contrast. Handheld photography with ease Sigma's OS (Optical Stabilizer) system offers effective correction of approximately 4 stops. As the stabilisation effect is visible through the viewfinder, it aids composition and accurate focusing. * The OS effectiveness will gradually decrease as the shooting distance becomes shorter. Floating inner focusing This Lens incorporates floating inner focusing which moves two Lens groups separately. This minimizes aberrations which occur as shooting distance changes, and enables stable rendering of the image from infinity to 1:1 magnification. This also corrects image distortion, especially when taking Close-Up pictures. Since focusing does not change its overall length, this Lens is easy to hold and use. Quiet and speedy AF HSM (Hyper Sonic Motor) provides quiet and high speed AF. It is also possible to use full-time manual focus, even if the Lens is set to autofocus. Rounded 9 blades diaphragm This Lens has a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas. This also creates smooth, rounded out of focus highlights when taking photos which have a strong light source in the background such as lights shining on the surface of water. APO Tele converters This Lens is compatible with Sigma's APO TELE CONVERTERS. With APO TELE CONVERTER 1.4x EX DG, it can be used as 147mm F4 AF* telephoto Macro Lens, and APO TELE CONVERTER 2x EX DG as 210mm F5.6 MF telephoto Macro Lens. This allows a greater working distance while still achieving 1:1 Macro magnification. * AF does not work from 0.45m close up photography. Tele Converter matching list Dedicated hood adapter When taking photos with APS-C sized digital SLR, the (supplied) dedicated hood adapter, which extends the length of the hood can be attached. This gives more protection from harmful lights that could negatively affect image quality. * When taking photos with full-size digital SLR, please remove HA680-01 in order to avoid the edges of image being blocked.

Sigma AF 105mm f/2.8 DG OS Macro Lens For Canon Mount
The Sigma 105mm f/2.8 EX DG HSM Macro Lens for Canon EOS Cameras delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to life-size (1:1) macro, as close as 12.2" (31 cm) without accessories. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion. Its non-rotating front lens group makes it easier to work with polarizing filters. A focus limiter helps divide the broad focus range into more manageable chunks.The "focus-free" mechanical design allows the lens to autofocus without any interference from the manual focus ring, making it easy to hold the lens without affecting the speed or normal operation of the autofocus function. Rugged mechanical construction also makes it durable enough for even the heaviest use required by professional photographers. An ideal lens for a wide variety of applications from nature photography to portraiture.The improved DG lens design for this lens corrects for various aberrations. This macro lens is specially coated to get the best color balance while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras. Sigma's own proprietary OS (Optical Stabilizer) system enables handheld close-up photography.
