Sigma 50mm F1.2 DG DN Art Lens Announced

Following hot on the heels of the Sigma 500mm F5.6 DG DN OS Sports & Sigma 15mm F1.4 DG DN Diagonal Fisheye Art lenses announced back in February, Sigma now brings us the Sigma 50mm F1.2 DG DN Art lens.

Weighing just 740g (E-mount) makes this lens 38g lighter than the Sony FE 50mm F1.2 GM lens (B&H Photo).

It will retail for $1399 US and £1299 in the UK, so it’s also $600 cheaper than the Sony which retails for $1,999.00.

The Sigma 50mm F1.2 DG DN Art is available for Sony E-mount and L-mount and should start shipping April 28th 2024. Pre-orders are already open.

The Sigma 50mm F1.2 DG DN Art lens features a bright F1.2 maximum aperture. Focusing is fast, quiet and accurate thanks to dual HLA focus motors.

Designed with 13 rounded diaphragm blades (a first for Sigma) for beautifully smooth bokeh and sharp images across the frame. The lens also implements a floating focus system that improves its short-range performance.

The lens has been optimised through its optical construction and focus group arrangements to significantly suppress focus breathing. Flare and ghosting are also effectively reduced, even when shooting in heavily backlit environments.

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, with a weight of just 740g for E-mount and 745g for L-mount.

The lens features 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 (not supported for Sony users).

There’s also a built-in aperture control ring with a lock switch and click on/off switch. An AF/MF switch is also present.

The lens is dust and splash resistant but not waterproof. The front element of the lens features a water and oil repellent coating.

A petal-type hood with lock button for secure attachment is also supplied with the lens.
