High performance, large aperture medium telephoto macro lens incorporating Sigmas Optical Stabiliser function.Sigmas medium telephoto macro lens incorporates Optical Stabilisation allowing the use of shutter speeds approximately 4 stops slower than would otherwise be possible. SLD glass provides good control of aberration and the floating inner focus system ensures high rendering throughout the focusing range. By using Sigmas APO Tele Converters, 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 Sigmas OS (Optical Stabiliser) 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 minimises 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 high-speed AF The HSM (Hyper Sonic Motor) provides quiet and high speed autofocus. It is also possible to use full-time manual focus, even if the lens is set to the AF position. 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 Sigmas 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. Dedicated hood adapter When taking photos with APS-C sized digital SLRs, the (supplied) dedicated hood adapter, which extends the length of the hood can be attached. This gives more protection from harmful light 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.

Large Micro Fibre Lens Cleaning Cloth - White

One of Sigmas finest creations yet, this lens sets a new benchmark for performance, offering quality that exceeds expectations in every way. Designed with a focus on sophisticated optical performance and abundant expressive power, our new Art line delivers superior image quality for high-level artistic expression. This new lens embodies the concept of our new Art lenses. Our Art line delivers high-level artistic quality Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. Developed with the maximum emphasis on artistic touch, our Art line lenses are designed to meet the expectations of users who value a creative, dramatic outcome above compactness and multifunction. Along with landscapes, portraits, still-life, close-up and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. The SIGMA 35mm F1.4 DG HSM is the first lens from the Art line. Compensate for colour aberration to ensure unsurpassed expressive performance Aberration is an important factor for the lens performance. To actualize a high-performance lens, one of the essential elements is aberration correction. When it comes to aberration, there are chromatic aberration of magnification and axial chromatic aberration. It is possible to correct the chromatic aberration of magnification in photo-editing software whereas axial chromatic aberration cannot be corrected afterwards. This lens incorporates FLD (F Low Dispersion) glass elements, which have performance equal to fluorite, and SLD (Special Low Dispersion) glass elements, and by optimizing the power alignment of the lens, both types of aberration have been corrected. The lens achieves ultra-high image quality through the entire focusing range. Also, by appropriate alignment of aspheric lenses, astigmatism and field curvature are corrected. The result is superior optimum resolution even in peripheral areas. Large maximum aperture of F1.4 In 2005, Sigma released a lens that has aperture value F1.4 designed for digital SLRs, SIGMA 30mm F1.4 EX DC HSM. Since then, we have produced high-performance lenses by incorporating the latest optical technique, such as the standard lens designed for a full size image sensor, the SIGMA 50mm F1.4 EX DG HSM and the medium telephoto lens with large aperture, SIGMA 85mm F1.4 EX DG HSM. This lens, SIGMA 35mm F1.4 DG HSM, is our fourth lens that achieves extraordinary expressive power at the aperture value at F1.4. For wide angle photography, it ensures excellent brightness with the large F1.4 aperture and a beautiful bokeh effect. Attractive blur effect Correction of coma aberration enabled less blur on a point light source in peripheral areas, and the function is best used for astrophotography and illuminations. It is also possible to create an attractive blur to the out of focus areas. The aspheric lens elements used as the first lens have secured peripheral brightness while correcting distortion. The rounded diaphragm creates an attractive blur to the out-of-focus areas of the image. Floating inner focusing system This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance for close-up photos. Flare and ghosting conscious design In order to achieve high rendering on this flagship lens, flare and ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. Hyper Sonic Motor The HSM (Hyper Sonic Motor) ensures high speed and quiet AF as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother AF is achieved.
