CLEARANCE Sigma 105mm f2.8 EX DG Macro OS Nikon fit Lens Ex display Lens, complete with all packaging, minor dust on elements due to being a demo model in store. 6 month warranty. 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. 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.
Clearance Canon EF 75-300mm F4-5.6 II DSLR Telephoto Lens Clearance Ex-Display model. May have minor cosmetic marks. 6 month warranty Affordable telephoto zoom lens DC autofocus motor Super Spectra coatings Lightweight design 58mm filter size 1.5m closest focusing distance The Canon EF 75-300mm F4.0-5.6 III lens incorporates the same optical system, construction and exterior design as the EF 75-300mm F4.0-5.6 III lens.

The lens has an electromagnetically actuated diaphragm, so that the aperture can be adjusted with utmost precision. Improved Coatings Transform Zoom Lens into a Di Type Lens Designed for Digital SLR CamerasBy employing “Internal Surface Coatings” (i.e., multiple-layer coatings on cemented surfaces of plural elements) and new multiple-layer coating technology on ordinary elements, ghosting and flare due to reflections that occur when light enters through the front element and reflections caused by the imagers themselves are reduced to the absolute minimum. Additionally, upgraded advanced quality control raises the level of resolution performance standards and prevents flare due to aberrations, resulting in a telephoto zoom lens suitable for photography with interchangeable-lens type digital SLR cameras. Macro Effect of 1:2 in Telephoto Zoom RangeFlipping a macro switch in the focal length range of 180mm to 300mm allows entry into the macro range, for photography as close as 95cm (37.4”) from the subject. In the macro range, one can take advantage of the telephoto effect and a maximum magnification ratio up to 1:2. (In normal shooting ranges, the minimum focus distance is 1.5m.) In addition, since the focal length in the macro range spans from 180mm to 300mm, zooming can also be used to adjust composition. Designed for Use on Both Digital and 35mm Film CamerasThe ultra-long telephoto zoom covering up to 465mm equivalent can be used on a digital SLR camera, while the wide-end 70mm can be used with a conventional 35mm film SLR camera for portraits and other moderately mid-range shots.

By including one or more low-dispersion elements in every element group, this lens ensures outstanding image quality throughout the zoom and focal range. * FLD glass is ultra-low-dispersion glass that offers the performance of the highest level. Highly transparent, its refractive index and dispersion are extremely low as compared to conventional types of glass. It offers characteristics very similar to those of fluorite, which is valued for its high anomalous dispersion. These characteristics minimise residual chromatic aberration (secondary spectrum), which cannot be corrected by the ordinary optical glass while helping to produce sharp, high-contrast images. Designed to minimize flare and ghosting - From the start of the design process, SIGMA measured flare and ghosting to establish an optical design that is resistant to strong incidental light sources such as backlight. Featuring a newly designed Hyper Sonic Motor - To achieve outstanding image quality and F1.8 brightness, SIGMA has enhanced its Hyper Sonic Motor (HSM). Optimizing the layout as well as the shapes of the individual parts, SIGMA has made the HSM 30 per cent slimmer than before. In turn, this slimmer HSM has made possible the combination of F1.8 brightness and high image quality in a zoom lens. Diaphragm unit designed for smooth operation - The diameter of the diaphragm is the second-largest in the SIGMA lens lineup after that of the SIGMA 200-500mm F2.8 / 400-1000mm F5.6 EX DG, necessitating smoother and quicker operation than ever before. To achieve this goal, the diaphragm blades feature Carbon Feather film, and the diaphragm unit features a new polycarbonate made with fluorine. Thanks to these innovations, diaphragm operation is exceptionally smooth even during continuous shooting, while the new polycarbonate is exceptionally durable and wear-resistant. Inner focus and inner zoom - Since its release, the SIGMA 18-35mm F1.8 DC HSM Art has been widely used for videography. Understanding that the SIGMA 18-35mm F1.8 DC HSM Art and the new SIGMA 50-100mm F1.8 DC HSM Art will often be used together, SIGMA has made the style of operation the same for both lenses, including the feel of focusing and zooming. Thanks to SIGMA's inner focus and inner zoom technologies, adjusting the focus and zoom rings does not change the length of the lens, and turning the zoom ring is not prone to causing focus shift. Tripod socket designed for stable, comfortable operation - The tripod socket is compact, making operation more stable and comfortable during handheld photography. Parts with electro-less nickel plating help ensure the quality and durability of the 90-degree click stops and smooth switching between the horizontal and vertical positions. The shape of the socket also enhances ease of handling and carrying when the lens is not attached to a camera. Extra-long Hood (Supplied) - The included lens hood is extra-long and features an anti-reflective coating to manage unwanted light. The hood also features rubber and anti-slip textures to make it easier for the photographer to hold while shooting. TSC used for a more compact structure and enhanced performance - Since the new material Thermally Stable Composite (TSC) is highly elastic, it exhibits minimal deformation. Parts made of TSC are therefore less prone to develop gaps between each other over time. The SIGMA 30mm F1.4 DC DN Contemporary features a lens barrel and aperture parts made of TSC, which contribute both to the compactness of the lens and the smooth functioning of the aperture system.
Zeiss Batis 25mm F2 Sony E mount Lens - CLEARANCE1802 Clearance item Ex demo All contents included Slight signs of use Boxed (some marks on box) Zeiss Batis 25mm F2 Sony E mount Lens The very close focusing distance of the 25 mm wide-angle lens supports the creative implementation of exceptional perspectives. Extremely uniform image quality is ensured right into the corners of the image. The lens is the perfect companion for shooting landscapes, architecture, street scenes and photojournalism. The ZEISS Batis autofocus lenses were developed especially for mirrorless, full-frame system cameras by Sony. The lenses are fully compatible with all E-mount cameras and offer protection against dust and splashes of water in addition to fast and easy autofocus. For creative work, the distance and depth of field can be read from the innovative OLED display. With the completely new lens design, the high-speed ZEISS Batis family offers perfect imaging performance. DesignOriginally developed for SLR cameras in which, due to the mirror box, a long back focal distance is required for short focal lengths (the distance between the back lens element and the film plane must be considerably longer than the focal length), the Distagon lenses (retrofocus design) are also ideal for mirrorless system cameras thanks to their optimized ray path. This also enables excellent image performance with large image angles for digital camera systems without mirrors. Smooth and reliable autofocusThe design of the autofocus system requires an extremely accurate shifting of particular lens groups. The focusing system of ZEISS lenses is designed to ensure a robust and smooth-running autofocus mechanism with the best imaging performance. Versatile full-frame lensThe powerful lens for the mirrorless full-frame system of Sony fulfils the highest requirements. Despite its compact design, the image meets the expectations of professional photographers. Excellent resolution and high contrastRichly saturated and vivid colours are a must in the creation of lasting impressions. However, stray light within an optical system leads to a lightening of the image that is particularly noticeable in the shadows. This reduces image contrast, with the result that exposures lack contrast and appear faded. To avoid this, ZEISS combines various specially developed technologies to reduce the undesirable effects of stray light. Robust and weatherproof metal constructionThanks to features that are designed to keep out dust and spray water, the lens is perfectly suited for critical outdoor conditions. It is also designed for many years of intensive use. Innovative OLED displayFor the first time, you can accurately read the focus distance and depth of field simply and intuitively on the OLED display on the lens. Especially in poor light conditions – excellent readability is always guaranteed.
