About the Sigma Art 30mm f/1.4 - Nikon F

This Sigma DC series lens has been designed exclusively for APS-C format digital SLR cameras and has been optically configured for these cameras.

It is a large aperture standardd lens which gives an equivalent field of view to a 45mm lens on a 35mm format digital SLR. Its extra-wide f/1.4 maximum aperture allows smooth bokeh (defocus), superb control over depth of field and strong low light performance as well as a bright viewfinder image.

As part of the “A” or Art Series, the 30mm f1.4 lens has been made to concentrate on optical quality and usability over range of features. Optically there is optimised power distribution for minimised curvature of field so images are sharp right into the corners of the frame. The lens also features a double aspheric lens for low spherical aberration, astigmatism and coma. Also there is a rear focus system which prevents focus-influenced variations in aberrations. During focusing there is no change in length of lens and no rotation of the front lens barrel, thus making focusing accurate and predictable as well as the lens being well suited to the fitment of filters. Focusing is actuated by the HSM (Hyper Sonic Motor) for fast and quiet focusing with the ability to manually override at will.

The lens has been designed at every stage to reduce flare and ghosting as well as having Super Multi Layer coatings, so these unwanted effects are reduces to a minimum. The brand new “A1” MTF measuring system has also been employed for the most accurate testing system to date.

With a hard plated brass bayonet mount and compatible with Sigma’s optional USB dock for firmware upgrades.

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, Sigma's 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 they have reorganized all their lenses into three product lines, they 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 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.

Design Concept
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
This 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.

Newly developed "USB DOCK" exclusively for new product lines
Attaching the lens to an optional USB DOCK plugged to your computer and using dedicated software “SIGMA Optimization Pro”, you can update the lens firmware and adjust parameters such as focus.

Evaluation with Sigma's own MTF measuring system "A1"
Sigma used to measure lens performance with MTF measuring system using conventional sensors. However, they have now developed their own proprietary MTF (modulation transfer function) measuring system (A1) using Foveon 46-megapixel direct image sensors. Even previously undetectable high-frequency details are now within the scope of quality control inspections. The SIGMA 30mm F1.4 DC HSM will all be checked using this “A1” before they are shipped.

  • Control over depth of field
  • Smooth bokeh
  • Excellent in low light
