Wide Zoom Range The Tokina AT-X 12-28mm F/4 lens has a super-wide to standard zoom range while maintaining a constant fast f/4.0 aperture. This makes ita very versatile lens for different photo applications such as scenery, street scenes photography and event coverage. The lens is designed for DSLR cameras with APS-C (DX) sized sensors. New Optical Design A new optical design using aspherical elements and super-low dispersion glass matches even the highest mega-pixel DX sensors cameras available today. One asphericallenselement is positioned in the front group. This together with another precision molded glass aspherical lens element placed in the rear group ideally focuses marginal light rays andmaintains sharpness at the edgeswhile also correcting distortion. The use of two different SD(Super-low Dispersion)glass elements,typeFK01 and FK03,correctschromatic aberration. The combination of all these specialized elements in the optical design yield excellent sharpness and colour. New auto focus mechanism The AF “GMR magnetic precision” control sensor is capable offastauto-focus. Tokina placed the new sensor closerto the drive unit in the lens for faster communicationbetween the controller and AF motor. This combined with the motor's high-precision focus control yields faster, more accurate auto-focus. Additionally, a brand new “SD-M” (Silent Drive-Module) has greatly lowered the sounds emitted by the auto focusdrive system allowing for much quieter AF. Both Canon and Nikon mounts have a built-in AF motor to make them auto-focus compatible with all current camera bodies.Compact body design The Tokin AT-X 12-28mmF/4 compact designmakes the lens easy to carry and handle. Manual focus is achieved through Tokina's one-touch focus clutch AF/MF mechanism. Simply slide the manual focus ring forward for auto-focus or back for manual focus operation. The lens focus ringis damped in the manual mode for smooth and precise focusing. In addition thelens has a 77mm filter size allowing filters such as the Hoya HD2low-profilecircular polarizer or UV to be used.

The Sigma 18-200mm f/3.5-6.3 DC HSM OS Lens is the second addition to the Contemporary line from Sigma's Global Vision. The Sigma 18-200mm lens was designed for APS-C sensors and features a new matte black finish, thermally stable composite material in its construction and smaller and lighter design then previous models. With exceptional performance, this 18-200mm camera lens does not sacrifice image quality for versatility. Having the ability to shoot from wide angle to telephoto is highly useful particularly for travel photography, landscape photography, street photography, portrait photography and nature photography. An improved minimum focusing distance of 14.7 inches paired with the use of Special Low Dispersion glass, the 18-200mm excels at bringing out great detail in close-up photography as well. A Hyper Sonic Motor (HSM) ensures quiet, accurate and fast autofocus and an optical Stabilizer (OS) helps compensate for camera shake. Make this lens your all-in-one lens to handle any shooting scenario.Lighter and smaller than its predecessorPerfect all-around travel lensGreat for close up photographyFront and rear lens caps and lens hood (LH676-01) is includedOptical Stabilisation (OS) helps compensate for camera shakeHyper Sonic Motor (HSM) ensures quiet, accurate and fast autofocusMinimum focusing distance of 0.39mContemporary line that covers a wide range of photography Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Among the three, the Contemporary line is a high performance line which incorporates the very latest technology making it possible to accommodate both high optical performance and compactness for use in various photography situations. Sigma has solved the difficult problem of keeping the size and weight down without compromising optical performance and function with the latest technology. This lens covers frequently used wide-angle to telephoto, as well as macro photography.New standard zoom up to 200mmSigma has always been producing a high performance standard zoom lens, dedicated for digital DSLR cameras, that covers up to 200mm by reflecting the latest technology. In 2005, Sigma released 18-200mm F3.5-6.3 DC as a smallest and lightest all-rounder lens in class that covers from wide-angle to telephoto range. Sigma, in 2007, incorporated OS (Optical Stabilisation) functionality, and in 2011, has successfully made the size of the lens even more compact. Now, this new lens has been redeveloped as the standard zoom lens from Sigma’s new product line, which has higher performance, is even smaller and lighter-weight, and on top of that, includes the macro feature. As an entry level interchangeable lens, it is capable of many photographic scenes.Diameter reduced by 4.6mm compared to its predecessorSigma pursued a compact size as an ideal everyday lens. From an early stage of development, SIGMA was determined to make the lens size compact, for example, by incorpor

The Sigma 70-200mm f2.8E FL ED OS is a full-frame Sigma lens primarily aimed at people interested in capturing fast-moving or fleeting action, such as in Wildlife Photography or sports.Compact and lightweight, this third-party lens is a superb and affordable alternative to native system lens. The balance of quality and pricing makes this a highly popular option for DSLR camera owners on a budget. Featuring a constant f/2.8 aperture enables photographers to have uncompromising control over their shutter speed and depth of field. This means that when progressing through the focal range of this lens, the aperture will not change unless the photographer is shooting in shutter speed priority mode or if they choose to adjust the aperture manually. The 9-blade aperture construction of this lens also helps to deliver attractive out-of-focus highlights as the lens creates strong separation between the intended subject and the background.To combat the instability inherent in using a large telephoto lens, the Sigma 70-200mm features Sigma’s advanced Optical Stabilisation (OS) technology. This allows users to take pictures with lower shutter speeds for up to 4 stops of compensation. Two modes of OS are offered, one for general shooting and another for panning motion, especially useful for covering activities such as motorsports. Three high-quality Super-Low Dispersion (SLD) glass elements are included in the structure of this 70-200mm lens, along with two Low Dispersion (FLD) elements that match the performance of fluorite. Multi-layer lens coatings and premium lens elements combine help to minimise the impact of flaring and chromatic aberrations, generally boosting overall image clarity. The 70-200mm also benefits from Sigma’s Hyper Sonic Motor (HSM) focusing technology, quietly and quickly moving its 22 glass elements in 17 groups, for accurate focusing. It also offers full-time manual focus override, enabling photographers to quickly make fine adjustments to their field of focus without switching off AF.The only real compromise creators should take into account when considering this lens is that it does not have dust and moisture sealing. However, the AF-S Sigma 70-200mm f2.8 EX DG OS HSM is one of the best affordable zoom lenses for DSLR camera owners. It focuses rapidly and will help deliver crisp images.
