The Aurora 85mm f/1.4 Lens from Sirui for Sony E-mount cameras combines an impressive optical design with a compact, lightweight build, delivering sharp imagery for both photography and videography. Its bright f/1.4 maximum aperture, paired with a 15-bladed diaphragm, creates smooth, beautiful bokeh that enhances your subject and helps it stand out against the background. To improve image quality and reduce ghosting, the lens incorporates aspherical, ED, and HRI elements. The front lens element is also treated with an antifouling fluorine coating, which helps protect it from dust and oil, ensuring clearer, more reliable shots.
Optical Design
The optical design of the lens features one aspherical lens, two ED lenses, and three HRI lenses, which reduce flaring and chromatic aberration while enhancing light transmission and image quality. Its 15-bladed diaphragm produces a smooth, pleasing bokeh effect, and with 14 lens elements arranged in 9 groups, the design ensures exceptional optical performance.
Low Light Master: F1.4 Aperture
The fast f/1.4 aperture allows more light to enter the camera, improving shutter speed and helping you capture stunning moments in low light. With more light reaching the sensor, you’ll need less fill lighting, and there’s no need for extremely high ISO settings, ensuring cleaner, more natural night scenes.
Physical Attributes
The lens features an AFL button for locking focus when pressed, or it can be customized for a preferred function. The AF/MF switch enables quick switching between manual and auto focus. A Click ON/OFF switch allows for tactile or smooth adjustments, and a USB-C port supports firmware updates for added functionality.
Fast, Accurate, and Silent Autofocus
The lens features a step motor that delivers fast, smooth, and nearly silent autofocus, making it ideal for capturing snapshots or fast-moving subjects.
- Photo: Supports camera Eye AF and object tracking for precise focus.
- Video: Provides fast and smooth follow focus for seamless filming.
85mm Born for Portrait Shooting
The 85mm focal length is ideal for capturing natural, distortion-free facial shots, unlike wide-angle lenses that exaggerate features. The moderate distance between the photographer and subject creates a more relaxed shooting environment.
When mounted on a Fujifilm camera, the Aurora 85mm f/1.4 lens offers a 128mm focal length effect, enhancing background blur for a more dreamy portrait. The fast f/1.4 aperture design separates the sharp subject from a soft, blurred background, producing a shallow depth of field and stunning portrait images.
