With an F3.5 aperture throughout the entire zoom range, the 10-20mm F3.5 is perfect for low light photography. Sigma wide angle lenses accentuate the relationship of subjects within a photo and thus become an important creative tool for photographers. Designed for APS-C DSLRs, this fast fixed aperture lens makes photography easier for the photographer who wishes to precisely control their depth of field and also for working with non TTL Flash systems. Super Multi-layer coating reduces flare and ghosting, four aspherical lenses provide correction for distortion and an inner focusing system eliminates front lens rotation, making it suitable for use of polarizing filters. Perfect for shooting landscape photography, architecture photography, interior photography, photojournalism, wedding photography, group/event photography and more.
DC - DC for Digital
These are special lenses designed for APS-C size sensors so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus!
ASP – Aspherical
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.
EX – EX Lens
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
HSM - Quiet and Fast Autofocusing
HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.
IF – Inner Focus
To ensure stability in focusing, this lens moves the inner lens group without changing the lens’ physical length.
Superior Image Quality
Two ELD (Extraordinary Low Dispersion) and one SLD(Special Low Dispersion)glass elements are employed for effective compensation of color aberration. The use of two glass mold and two hybrid aspherical lenses offer excellent correction for distortion and astigmatism and assure superior image quality. The super multi-layer coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range.
Minimum Focusing Distance of 24cm (9.4")
This lens has a minimum focusing distance of 24cm (9.4 inches) throughout the entire zoom range. This close focusing distance on such a wide-angle lens emphasizes perspective and allows the photographer to capture high quality images, not only of the foreground subject but also the surrounding scenery
