Is it worth choosing over the older 50mm F1.4 Art?

Yes for mirrorless users. It is smaller, lighter and has faster, quieter autofocus than the DSLR-era design, with similar or better optical performance.

How does it compare with Sony's 50mm F1.4 GM?

The Sigma is close in sharpness and aperture but generally larger and heavier than the Sony GM. The Sony focuses faster and costs more; the Sigma is the value pick.

Does it work on APS-C Sony bodies?

Yes, with the E-mount. On APS-C it behaves like a 75mm-equivalent lens, so it becomes a short telephoto portrait lens.

Is the autofocus good for video?

The stepping motor is quiet and smooth, which helps for video. Focus breathing is visible, so it is not the best choice for serious video work.

The lens, front and rear caps, a lens hood and a soft case.

Is it weather sealed?

It has a dust- and splash-resistant mount and barrel seals, but it is not fully waterproof.

About the Sigma 50mm F1.4 DG DN Art Full Frame Lens For Sony E-Mount

The Sigma 50mm F1.4 DG DN | Art is a large-aperture standard prime lens designed for full-frame Sony E-mount mirrorless cameras. It has a fixed 50mm focal length and a maximum aperture of f/1.4. The optical design uses 14 elements in 11 groups, including 3 aspherical elements and 1 SLD glass element. It is built to suppress aberrations such as astigmatism and field curvature, and to keep coma flare minimal for star and night scenes.

Focusing is driven by an HLA (High-response Linear Actuator) linear motor that moves the focus lens directly, without gears. A single double-sided aspheric lens serves as the focus element. Focusing is quiet and fast, and suits low light, moving subjects and video. The inner focus system adjusts focus without changing the length of the lens barrel.

The barrel has a focus mode switch (AF/MF), an aperture ring with a click on/off switch, an aperture ring lock switch, and an AFL button that can be assigned a function from the camera. The lens has a dust and splash resistant structure with special sealing at the mount. The front element has a water and oil repellent coating. Super Multi-Layer Coating reduces flare and ghosting. The lens is made in Japan at Sigma's Aizu factory.
