Top specs

  • Type

    Standard

    The visual they offer is very close to the human eye and is often called "normal". They provide a natural result with minimal distortions and their focal distance is usually 40-55mm in full frame, 25-40mm in crop frame, and 80-100mm in medium format.

  • Mount

    The type of mount that the camera body must have in order for the lens to be fully functional when attached to it.

    2. Some lenses can be used with older mounts from the same manufacturer, sacrificing certain functions (e.g. autofocus), or even with mounts from other manufacturers using an adapter.

  • Item

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

    Fixed Focal Length

    Lenses with fixed optics are usually of higher quality than a corresponding zoom lens at the same focal distance. They are also called "fixed" or "prime" lenses.

  • Sensor Type

    Full Frame

    Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

    For example, a full frame lens with a focal length of 50mm (standard) on a camera body with a crop factor of 1.6 will function with a perspective as if it were an 80mm lens (telephoto).

    The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).

  • Maximum Aperture (f)

    Opening the diaphragm determines the amount of light received by the camera and affects the depth of field.
    2. The most open aperture of a lens is called the maximum. The more open the aperture (smaller f-number), the shallower the depth of field.

Description

Description

The Sigma 50mm f/1.4 DG DN Art redefines the classic standard lens for Leica L-mount mirrorless cameras. Designed from the ground up to deliver outstanding artistic expression and uncompromising optical quality across the full frame. Its fast f/1.4 aperture ensures excellent low-light shots with smooth, natural background separation. It features an advanced linear focusing mechanism that delivers lightning-fast, quiet and reliable tracking of moving subjects. Its compact, lightweight design offers excellent portability, making it the ideal companion for any creative project.

50mm Focal Length and Art Series Philosophy

The 50mm focal length is considered the ultimate benchmark for a natural human perspective.
This lens is the latest addition to SIGMA’s renowned Art F1.4 series.
It has been designed exclusively for modern full-frame mirrorless cameras with a Leica L Mount.
It reimagines photographers’ needs from the ground up across a wide range of creative situations.
It offers unparalleled versatility for artistic expression, portraits, snapshots, and everyday photography.
It helps professionals and demanding creators capture their vision with outstanding aesthetics.

Bright f/1.4 Aperture and Natural Bokeh

The impressively large maximum aperture of f/1.4 allows exceptional amounts of light to reach the sensor.
It enables comfortable, reliable photography in dark environments and low-light conditions.
It creates a large, striking and beautiful bokeh effect that harmoniously isolates the subject.
Out-of-focus areas are rendered without distracting color distortions or harshness.
The final image stands out for its natural dimensionality and impressive depth of field.
It ensures uniform, balanced image quality across the entire frame, enhancing expressive impact.

Optical Design with 3 Aspherical Elements and SLD Glass

The optical design of the lens comprises 14 elements arranged in 11 groups.
It incorporates three high-precision aspherical elements to control geometric aberrations.
It also includes one SLD (Special Low Dispersion) glass element to minimize chromatic aberrations.
It effectively eliminates astigmatism and field curvature that are not automatically corrected by the camera.
It maintains exemplary resolution and sharpness from the center to the edges of the frame.
It delivers unparalleled clarity, high color fidelity, and impressive contrast in every shot.

Suppression of Sagittal Coma Flare and Astrophotography

Particular emphasis has been placed on the effective suppression of the optical aberration known as sagittal coma flare.
This aberration is extremely difficult to correct during post-processing.
Thanks to its specialized design, the lens delivers precise reproduction of point light sources without distortion.
Bright points and stars retain their spherical shape, even in the corners of the frame.
This makes the lens an ideal tool for photographing the starry night sky.
It meets the most demanding requirements of astrophotography with outstanding results.

HLA AF Linear Motor and Compact Slim Body

It is the first lens in the Art series for mirrorless cameras to feature an HLA (High-response Linear Actuator) motor.
It uses a double-sided aspherical lens element as a moving focus element to minimize weight.
It delivers lightning-fast, silent and precise autofocus with outstanding tracking capability.
It excels at capturing moving subjects and street scenes, as well as in demanding professional video productions.
At the same time, it retains a compact, slim body, optimizing weight and overall size.
It offers the ideal combination of outstanding optical performance and exceptional mobility for everyday use.
