The "superzoom" Sigma 18-250mm f3.5-6.3 DC OS Macro Lens is a cutting-edge camera construction marvel and also a top dog amongst telephoto lenses. From its basic F22 minimum aperture and 62mm diameter filter to the more advanced features, you can see that it walks its talk. It has a fast and silent HSM-driven auto-focus action and rounded 7-blade diaphragm that performs quick focusing actions and artistically gives out-of-focus parts pleasant blur. Thanks to its reliable super multi-layer coating and SLD glass elements, aberrations, flare, and ghosting are kept to minimum. The strongest feature of the Sigma 18-250mm f3.5-6.3 DC OS Macro Lens a team comprising of a TSC lens barrel, an optical stabiliser (OS), and a brass bayonet mount, that all in all maintains stability of the hardware and eliminates image anomalies caused by mechanical and electronic factors. Have your photo shoots as stable as this top-notch lens. It is compatible only with APS-C DSLR Cameras.
Product Features in Detail
High Performance, Compact, High Zoom Ratio Lens designed exclusively for digital SLR cameras
By revolutionizing the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC OS HSM, this new lens achieves a compact size and a minimum focusing distance of 35cm. New material, Thermally Stable Composite (TSC) maintains its structure and has little contractility especially in varying temperatures, is incorporated into the lens barrel. It is convenient when you wish to keep your equipment to a minimum and yet still be prepared for all opportunities and situations, such as travels.
A wide range of photography is possible in one lens
Covering wide angle 18mm to telephoto 250mm, this versatile lens designed exclusively for digital SLR cameras, is suitable for all-purpose photography including landscape, sport and macro photography. It is convenient when you wish to keep your equipment to a minimum and yet still be prepared for all opportunities and situations, such as travels.
Excellent for macro photography
Close-up capability is improved with the minimum focusing distance of 35cm throughout the entire zoom range, and maximum magnification ratio of 1:2.9. In APS-C size equivalent, macro photography with approximately 1:2 magnification ratio is possible. In addition, with this lens, the size and flaming of subjects can be adjusted by rotating a zoom ring, making macro photography easier than using fixed focal macro lens. For further convenience, the maximum magnification ratio at each focusing distance appears on the side of the lens barrel.
Revolutionizing the design foundation results in compact size
Optimization of the power arrangement by such as incorporating double-sided aspherical lenses, and reexamination of design, the filter diameter size is reduced. This compact size lens has the approximately 13x high zoom ratio with the filter size of diameter 62mm, and dimensions of diameter 73.5mm x Length 88.6mm. It ensures portability and overall ease of use, making it perfect for travel and leisure photography.
New material TSC (Thermally Stable Composite)
The new material "TSC (Thermally Stable Composite)", which has little contractility especially in temperature changes, as well as maintaining firmness, is incorporated into the lens barrel. Compared to Polycarbonate which is generally used, TSC has higher elasticity by approximately 25%. Since thermal shrinkage is low, it has high affinity to metal parts which contributes to high quality product manufacturing. It also contributes to the parts such as the zoom ring and scaling to be slimmer.
Brass made bayonet mount
This lens incorporates brass made bayonet mount which has both high accuracy and solidity, same as the mount for camera body. The special treatment to reinforce the strength is applied on the surface to make it a high quality lens that is resistant for long-term use.
Optical Stabiliser (OS)
Sigma's own unique Optical Stabiliser (OS) function is incorporated. It offers effective correction of approximately 4 stops, which makes it possible to compensate camera shake even in macro range photography where a small blur can be easily identified. When photographing a moving subject such as motor sport, it automatically detects camera move, and offers effective correction for camera shake.
*The OS effectiveness will gradually decrease as the shooting distance becomes shorter.
*Sony and Pentax mounts are not incorporated with OS function.
Superior optical performance
SLD (Special Low Dispersion) glass element offers excellent correction of color aberration. Three aspherical lenses including double-sided aspherical lens together with the latest design, prevent and correct all types of aberrations including astigmatism, achieving high quality images throughout the entire zoom range.
Flare and ghosting conscious design blades
From an early stage, flare and ghosting are thoroughly measured to establish the design which is resistant to strong incident light such as backlight. Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high contrast images even in backlit conditions. Supplied petal-type hood can be attached to block out extraneous light which has a harmful influence on rendering of the lens, and prevent internal reflections to occur.
Hyper Sonic Motor
The HSM (Hyper Sonic Motor) ensures fast and quiet auto-focusing.
The rounded 7 blade diaphragm creates an attractive blur to the out of focus areas.
