My Photography Gear 2 - The Sigma 10-20mm F4-5.6 EX DC HSM

Dear photograhy enthusiasts, today, i would like to introduce you with another useful tool found in my photography backpack.  The Sigma 10-20mm F4-5.6 EX DC HSM is one of my favourite lenses which I recently acquired.  It offers a wide angle range, ideal for landscape and architecture photography.  Wayback, photographers making use of APS-C sensor cameras lacked behind in the wide-angle field.  This lense, when introduced, deflected this barrier and made it possible for a wide range of photography enthusiasts to capture some stunning landscape and architecture shots.

The Sigma 10-20mm F4-5.6 EX DC HSM is a solid, well-built lens with good operational characteristics, which provides some really excellent imaging results. The front element does not extend, which makes it possible to easily attach to it a filter, either directly or through an operator. This is very relevant, as the majority of those looking for such a lens require focal range at scenic and therefore attaching a filter becomes a must.  Optically, this lens is impressive. Chromatic aberration features slightly in this lens but let’s face it, this is a common problem with ultra-wide angle lenses. The images are consistently sharp and crisp.  Infact such quality betrays its focal range and price tag.

Here are some technical data which one ought to know:

·         A DC series lens designed exclusively for use with smaller chip APS-c or 4/3 cameras,

·         HSM (Hyper-Sonic Motor) allows for fast auto focus speeds & quiet shooting and is capable of full-time manual operation,

·         Three aspherical lens elements offer excellent correction for distortion and Three SLD (Special Low Dispersion) glass elements employed for effective compensation of colour aberration,

·         Internal Focusing System allows the convenient use of a polarizing filter for creative effects & improves the optical performance of the lens at various distances,

·         Awarded the TIPA award, best consumer lens in Europe 2006.

This is a decent lens which streches the ability of photography enthusiats to a limit of 10mm wide-angle-view at a decent price. I strongly recommend this lens!
