Sigma 18-250mm f/3.5-6.3 DC Macro OS Lens Unboxing
   Hello Everyone! In this video we have a wonderful super zoom lens to open up. Its the Sigma 18-250mm Macro Lens. This is one of Sigmas older lens line up but has only been around for a few years and is still a favorite of many photographers who prefer the ease of an all-in-one lens. So lets open up the box and show you what you get for your hard earned cash.




About this product:

The Sigma 18-250mm F3.5-6.3 DC Macro OS HSM lens[1] is equipped with Super Multi-Layer Coating to reduce flare and ghosting, a Hyper Sonic Motor (HSM) to ensure fast and quiet auto-focusing, and a rounded, seven-blade diaphragm to create an attractive round blur to the out of focus areas. The lens features a brass-made bayonet mount applied on the surface to reinforce strength for long-term use and enable high accuracy and solidity. Sigma optimized this lens’ power arrangement by incorporating double-sided aspherical lenses and reexamining the design to achieve a more compact filter diameter. The lens has an approximate 13x high zoom ratio with a filter size of 62mm in diameter. Sigma’s unique OS system, as well as one Special Low Dispersion (SLD) glass and three aspherical lens glasses, compensate for camera shake and enable correction of color aberration, respectively. The lens has 16 Elements in 13 Groups and has a maximum magnification of 1:2.9. It is 2.9in x 3.5in and weighs in at 16.6oz (470g).
