This large-aperture standard lens gives owners of mirrorless cameras the opportunity to experience the fun of shooting wide open, with F1.4 brightness. Photographers will enjoy the beautiful bokeh effect that only a large-aperture lens can offer and the exceptionally sharp optical performance expected from a fine prime lens. A prime lens with a focal length of around 50mm and F1.4 brightness offers an angle of view very similar to human vision. The photographer can use the shallow depth of field at wide-open aperture to take stunning portraits and tabletop still life shots or can close the aperture for greater depth of field and shoot landscapes or snapshots. Photographers can experience F1.4 brightness and standard lens functionality with a 35mm equivalent focal length of 60mm on the Micro Four Thirds system and 45mm on the Sony E-mount system.
Combining compactness with outstanding optical performance
The front lens element features high-refractive index, high-dispersion glass for extra power and a shorter overall lens length. To optimize the lens for mirrorless cameras, two aspherical lens elements help ensure outstanding image quality and overall compactness. The lens features SIGMAs inner focus technologies, while lighter lens elements in the focus lens group make possible a more compact actuator. Moreover, this lens offers outstanding stability whether the photographer is shooting handheld or has the camera placed on a surface. Structurally, the lens features materials and parts that contribute to its compact, lightweight structure. In summary, this is an unprecedented lens that combines outstanding optical performance with exceptional portability and usability.
A compact, lightweight lens offering outstanding image quality with F1.4 brightness
In addition to featuring an optimized layout and power distribution, this Sigma 30mm f/1.4 DC DN Contemporary Lens (Sony Fit) incorporates one aspherical lens element and one double aspherical lens element, as well as an element made of a high-refractive-index, high-dispersion glass with high anomalous partial dispersion. By effectively leveraging these technologies, the lens delivers an outstanding level of light to the edges of the image while minimizing lateral chromatic aberration. To correct distortion, the lens takes advantage of the image correction capabilities of the mirrorless camera body, using the corrective power of the optical system to enhance sharpness.
Shallow depth of field for a beautiful bokeh effect
The large-diameter lens with F1.4 brightness makes possible a shallow depth of field for a beautiful bokeh effect unavailable until now in a standard lens for mirrorless cameras.
Designed to minimize flare and ghosting
From the start of the design process, SIGMA took steps to minimize flare and ghosting and establish an optical design that is resistant to strong incidental light sources such as backlight.
Fast and smooth AF
By incorporating a stepping motor, the lens offers exceptionally quick and quiet autofocusing performance. This feature is especially useful when using the camera to take videos. This lens is also compatible with Sony E-mount Fast Hybrid AF.
Extra-long Hood (Supplied)
The included lens hood is extra-long and features an anti-reflective coating to manage unwanted light. The hood also features rubber and anti-slip textures to make it easier for the photographer to hold while shooting.
The 9 blades rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
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.
