SIGMA 50mm F1.2 DG DN Art - L Mount
Bright F1.2 aperture with outstanding optical quality
The SIGMA 50mm F1.2 DG DN Art features a bright F1.2 aperture with a 13 rounded diaphragm blades that produces beautiful bokeh effects.
Utilising the latest optical design techniques, the lens produces sharp images across the whole frame with exceptional contrast and colour.
Focus breathing is also heavily-suppressed allowing videographers to capture creative shots with ease
Impressive optical quality through the entire focusing range
By correcting spherical aberration, sagittal coma flare, axial chromatic aberration, and other aberrations such as double-line bokeh, the lens produces a
natural bokeh with a smooth blur and without colour bleeding from the focal plane.
The lens also implements a floating focus system that improves its short-range performance.
This ensures a high-level of optical quality throughout the entire focusing range.
SIGMA's first ever 13 diaphragm blade lens
New to the SIGMA 50mm F1.2 DG DN Art is the implementation of a 13 rounded diaphragm blade design.
When shooting subjects at F1.2, the aperture maintains its circular shape.
Photographers can effortlessly create portraits and still life shots with impressive background separation and pleasingly round bokeh balls.
Designed to minimise focus breathing, flare and ghosting
The lens has been optimised through its optical construction and focus group arrangements to significantly suppress focus breathing.
Focus shift is also minimised, creating a natural focus shift look when recording video.
Flare and ghosting are also effectively reduced, even when shooting in heavily backlit environments such as street and event photography.
Dual HLA motor
Effortlessly and reliably focus on your subject thanks to the newly revised focusing system.
The lens features a floating focusing system that uses dual HLA (High-response Linear Actuator) motors.
The use of these motors reduces the lens's size without compromising performance.
Focusing is fast, quiet and accurate, perfect for every situation.
Unique lens and mechanical design
By utilising state-of-the-art production technology at SIGMA's manufacturing base in Aizu, Japan, each glass element has been reduced
in size whilst retaining elements with a high refractive index.
Four aspherical glass elements and a floating focus system are also implemented to further reduce the lens's overall size and effectively reduce aberrations.
These reductions make the SIGMA 50mm F1.2 DG DN Art the lightest lens in its class.
It is 30% lighter than the SIGMA 35mm F1.2 DG DN Art which shares the same aperture.
A variety of shooting assist functions
The lens is equipped with an AFL button which can be assigned to a range of functions via the camera menu on supported cameras.
L-Mount users can customise the button further using the UD-11 USB Dock
Effortlessly control the depth-of-field using the built-in aperture control ring and make your images stand out from the crowd.
The aperture ring lock switch prevents the ring from accidental knocks.
Use the aperture click switch to turn the click of the aperture ring on or off. - Ideal for when shooting video and quiet scenes.
Dust and splash resistant structure
In addition to a dust and splash resistant structure*, the front element of the lens features a water and oil repellent coating, allowing
photographers to shoot without concern even in harsh outdoor environments.
* The structure is designed to be dust and splash resistant, but not waterproof.
- Be careful not to bring the lens in contact with a large amount of water.
-
- Water inside the lens may cause major damage and even render the lens unrepairable
-
Including a petal-type hood with lock
A dedicated petal-shaped hood is supplied. A locking mechanism is provided for secure attachment.
