Sharp, Compact, and Artistically Expressive

The Sirui Aurora 85mm f/1.4 AF lens combines professional-level optics with lightweight engineering, making it ideal for both photography and video work.

With advanced optical elements and modern control features, this lens is built for creators who need both performance and portability.

Focal Length: 85mm

A classic short-telephoto focal length, 85mm is widely favored for portraiture thanks to its natural compression, flattering perspective, and ability to isolate subjects from their background. It provides enough working distance to keep subjects comfortable while capturing expressive detail.

Maximum Aperture: f/1.4

The bright f/1.4 aperture offers exceptional low-light performance and outstanding depth-of-field control. It allows for faster shutter speeds in dim environments and creates a shallow focus plane that beautifully separates subjects from their backgrounds.

Minimum Aperture: f/16

Narrow the aperture to f/16 for deep focus and maximum sharpness across the frame when shooting landscapes or scenes where you need extensive depth of field.

Aperture Blades: 15-Bladed Diaphragm

The 15 rounded diaphragm blades create exceptionally smooth, circular bokeh highlights, even when stopped down slightly. This design enhances the aesthetic quality of out-of-focus areas—ideal for artistic portraiture and cinematic video.

Lens Mount: Sony E

Designed for Sony E-mount full-frame mirrorless cameras, this lens seamlessly integrates with Sony’s autofocus systems, offering quick and accurate AF performance for both stills and video.

Format Compatibility: Full-Frame

Covers full-frame sensors, delivering edge-to-edge image quality. Also compatible with APS-C Sony E-mount cameras, where it offers an equivalent focal length of approximately 127.5mm.

Minimum Focus Distance: 2.79 ft / 85.04 cm

Get close to your subject while maintaining a flattering perspective. This minimum focus distance is ideal for headshots, tight portraits, and detail work while maintaining a comfortable working distance.

Magnification Ratio: 0.12x (1:8.33)

Provides modest close-up capabilities, making it suitable for capturing fine details like jewelry, flowers, or hands in portrait settings, without requiring macro-level proximity.

Focus Type: Autofocus with Manual Override

Fast, quiet, and accurate autofocus performance with the ability to manually override focus at any time for precision control. Excellent for both still and video shooters who need flexibility.

AF/MF Switch

A dedicated physical switch allows instant toggling between autofocus and manual focus modes, providing responsive handling during dynamic shooting scenarios.

AFL Button (Autofocus Lock / Custom Function)

This programmable button can lock focus when pressed or be reassigned to a custom function depending on your camera’s capabilities, enhancing your control over the lens during complex compositions.

Click ON/OFF Switch for Aperture Ring

Choose between tactile clicked aperture stops (great for stills) or smooth, stepless aperture adjustments (perfect for silent video recording and cinematic exposure control).

USB-C Port for Firmware Updates

Futureproof your lens with a built-in USB-C port for easy firmware updates. This allows Sirui to improve autofocus performance and compatibility over time without the need for service center visits.
