Unlock Wide-Angle Creativity with the Sigma 10-20mm F4-5.6 EX DC HSM
Step into a world of ultra-wide possibilities with the Sigma 10-20mm F4-5.6 EX DC HSM – a lens built to broaden your perspective without breaking the bank. Designed specifically for APS-C sensor DSLRs, this versatile ultra-wide zoom delivers expansive coverage ideal for landscape, architectural, interior, and creative environmental photography.
At 10mm, this lens offers one of the widest fields of view available in the APS-C category, making it a must-have for photographers who want to fit more into the frame. From dramatic skies and sweeping cityscapes to tight indoor scenes where space is limited, the Sigma 10-20mm brings dynamic storytelling into every shot.
What sets this lens apart is its advanced optical construction: 14 elements in 10 groups, incorporating three Super Low Dispersion (SLD) glass elements to reduce chromatic aberration and three aspherical elements to correct for distortion and edge softness. The result? Crisp, clean images with excellent clarity across the entire zoom range.
Autofocus performance is equally impressive, thanks to Sigma’s HyperSonic Motor (HSM) technology (available in Canon, Nikon, Sigma, and Four Thirds mounts). This ultrasonic motor ensures quick, near-silent focusing — perfect for both stills and video. For Sony and Pentax users, the lens uses a screw-drive focus system that still delivers reliable performance.
Weighing just over 465g, the 10-20mm is surprisingly compact and lightweight, making it a great companion for travel, outdoor excursions, or day-long shoots. It also benefits from Sigma’s EX finish, offering a professional look and feel with added durability. And with a minimum focusing distance of just 24cm, you can experiment with close-up wide-angle perspectives that create incredible depth and drama.
One of the standout features of this lens is its incredible price-to-performance ratio. It consistently outperforms expectations, providing results that rival higher-end lenses — often at half the cost. For photographers looking to add an ultra-wide zoom to their kit without investing in expensive manufacturer-branded options, the Sigma 10-20mm F4-5.6 is a clear winner.
While the market has seen newer contenders emerge, including Sigma’s own premium f/3.5 version and rival offerings from Tamron and Olympus, this model remains a high-value choice that balances optical quality, build, and affordability with outstanding effect. Whether you're just getting into wide-angle photography or want to expand your creative toolkit, the Sigma 10-20mm F4-5.6 is a powerful and reliable lens that delivers where it counts.
