Sigma 35mm f/1.4 DG II Art Lens - Sony E

The f/1.4 aperture allows for excellent performance in low-light conditions and enables a shallow depth of field, creating a blurred background (bokeh) to make your subject stand out.

Yes, the Sigma 35mm f/1.4 DG II Art Lens is optimized for both stills and video, featuring improved autofocus for smooth focus transitions and a quieter operation.

A floating focus system adjusts the position of lens groups independently to correct aberrations that occur at different focusing distances. This results in sharper images across the frame, especially at close focusing distances, and contributes to a more compact lens design.

The lens uses a 67mm filter size.

The DG II version features faster focusing, improved image quality wide open at f/1.4, and a more compact and lightweight design.

This lens is designed specifically for Sony E-mount. Using it on cameras with other mounts would require an adapter, and compatibility/performance may vary.

The lens weighs approximately 525g.

Ensure the camera's firmware is up to date. Clean the lens contacts and camera mount contacts. Try resetting camera autofocus settings. Confirm the camera's AF mode is appropriate for the subject.

Ensure the lens is properly mounted and locked. Check that the focus is accurately set on the subject. Clean the lens elements. Shoot at a slightly smaller aperture (e.g., f/2.8 or f/4) if maximum sharpness wide open is not required.
