Sigma 30mm f/1.4 Art DC HSM Lens for Canon

Sigma 30mm f/1.4 Art DC HSM Lens for Canon

Placed in the Art line, this large-aperture standard lens with an angle of view equivalent to 45mm on a 35mm camera is a superb go-to lens for artistic photography on an APS-C format digital SLR. Offering the bright f/1.4 aperture and an angle of view extremely close to that of human vision, this lens is ideal for many different types of photography. This 30mm lens Art boasts a Hyper Sonic Motor, Super Multi-Layer Coating and a design featuring Thermally Stable Composite Material. The HSM ensures quiet, accurate and high-speed autofocus; the Super Multi-Layer Coating reduces flare and ghosting, while the TSC reduces expansion and contraction of the internal lens barrel. A rear focus system prevents focus-dependent variation in aberration, making high-level image quality possible throughout the entire image. With their unchanging barrel length, this lens also enhance balance and stability for the photographer. An optimized autofocus algorithm achieves smooth focusing while a 9 blade rounded diaphragm creates beautiful bokeh.

Art Lens

Engineered for those who see photography as a critical expression of self, Sigma's Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.

DC for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. DG lenses provide exceptionally high contrast along with subtle gradations in tone and color.

Hyper Sonic Motor Focusing (HSM)

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.

RF for Rear Focus

A rear focus system that prevents focus-dependent variation in aberration, making high-level image quality possible throughout the entire image. With their unchanging barrel length, these lenses also enhance balance and stability for the photographer.

TSC (Thermally Stable Composite)

The barrel of the lens features a new TSC (Thermally Stable Composite) that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens. TSC also makes possible slimmer forms for parts like zoom rings and scaling rings.

Flare and Ghosting Reduction

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
