Featuring an advanced design and the latest manufacturing technologies, Sigma 30mm F1.4 DC HSM | A, the large-aperture APS-C format standard lens delivers the highest level of image quality worthy of the Art line. The photographer can leverage the shallow depth of field that creates beautiful bokeh for snap shots, portraits, landscapes, and many different styles of photography.
Our Art line delivers high-level artistic quality
Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. Developed with the maximum emphasis on artistic touch, they are designed to meet the expectations of users who value a creative, dramatic outcome above compactness and multifunction. Along with landscapes, portraits, still-life, close-up and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes.
A large aperture F1.4 standard lens
Sigma pioneered the large-aperture APS-C format standard lens category with its 30mm F1.4 lens in 2005. Now that we have reorganized all our lenses into three product lines, we are proud to introduce the fully updated “SIGMA 30mm F1.4 DC HSM”. Offering the shallow depth of field of F1.4 and an angle of view extremely close to that of human vision, this lens stimulates the desire to create and is ideal for many different types of photographic expression. The bright viewfinder also aids focusing and composition of images.
Outstanding image quality for enhanced photographic expression
Convenient angle of view of a standard lens challenges photographers’ expression. The Sigma 30mm F1.4 DC HSM | A has outstanding optical performance in order to fully perform its best expressive quality at all shooting distances. Optimized power distribution minimizes field curvature thereby preventing a loss of image quality at the edges of photographs. The use of a double aspheric lens minimizes spherical distortion, astigmatism and coma. Coma of point light sources is minimized near the edge of the image, and an attractive round bokeh effect is produced at large-aperture settings
Incorporating a Rear Focus system
The lens incorporates 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. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.
Flare and ghosting conscious design
From an early stage, flare and ghosting are thoroughly measured to establish the design which is resistant to strong incident light such as backlight. Sigma’s Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high contrast images even in backlit conditions.
Minimum focusing distance of 30cm
The maximum magnification is 1:6.8, making it excellent for close-up photography.
Hyper Sonic Motor (HSM)
The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. It also enables full-time manual focusing capability which allows sensible focus adjustment by simply rotating the focus ring.
Incorporating Rounded diaphragm
The 9 blade rounded diaphragm creates an attractive round bokeh at large-aperture settings.
The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the designs of the lens cap and AF/MF changeover switch have been improved. In order to ensure high accuracy of the product, all metallic parts and the new compound material, TSC (Thermally Stable Composite), which has a high affinity to metal parts, are housed internally.
Brass made bayonet mount
his lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
