SIRUI Aurora 35mm F1.4 Full-Frame Autofocus Lens for Sony E in More Detail

Image quality

The Aurora 35mm F1.4 delivers consistently high image quality even on high-resolution full-frame sensors. The optical design combines aspherical elements with ED, SED, and HRI glass, with each used to address specific optical issues such as spherical aberration, colour fringing, and contrast. These elements work optically to maintain edge definition and colour accuracy across the frame.

At wider apertures, the lens produces a shallow depth of field with smooth background separation, while maintaining usable sharpness across the image. Stopping down increases frame-wide consistency, which is particularly useful for documentary and travel photography where fine detail can be important from centre to edge. Distortion and chromatic aberration are well controlled, helping images retain a natural look without heavy post-processing required.

Autofocus performance

Autofocus is driven by an STM motor, used for its accuracy and low noise. This makes the lens suitable for both stills and video, particularly when working in quiet environments or recording audio on-camera. Focus transitions are smooth, which benefits video and gimbal-based shooting.

The lens supports camera-based subject detection features, including eye detection and tracking on compatible camera bodies. For stills photographers, this translates into dependable focus acquisition in fast-moving or reactive situations, such as street or event photography. Manual focus is still available via a long-throw focus ring, offering fine control when MF is preferable.

Video features

Although not branded as a cine lens, the Aurora 35mm F1.4 includes several features that support video workflows. Focus breathing is kept to a minimum, helping maintain consistent framing during focus pulls. The aperture ring can be switched between clicked and de-clicked operation, allowing smooth exposure changes during recording.

The lightweight design also makes the lens easy to balance on a gimbal, reducing setup time for solo creators especially. Combined with reliable autofocus tracking, this makes it a good option for run-and-gun video, vlogging, and documentary where speed and consistency are key.

Handling, controls and stabilisation

The lens is made from metal and is relatively light for a full-frame f/1.4 prime. On Sony E-mount, it weighs approximately 490g, which is very usable even for extended handheld shooting. Weather sealing protects against dust and light moisture, while a fluorine coating on the front element helps resist fingerprints and smudges during regular use.

On-lens controls include an AF/MF switch, an iris lock to prevent accidental aperture changes, a function button that can be assigned through the camera, and a dedicated click on or off switch for the aperture ring. These controls allow photographers and filmmakers to adjust their setup without diving into camera menus, supporting a more direct shooting experience.
