Sigma 18-250mm f3.5-6.3 DC MACRO OS HSM Zoom Lens f/Canon EOS 883101

Sigma 18-250mm F3.5-6.3 DC MACRO HSM, a compact, high zoom ratio lens, covering wide angle, telephoto and macro photography. By revolutionizing the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC 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 framing 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. 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.
