New Sirui 15mm f/1.6 and 24mm f/1.4 lenses are a bargain for landscape and astro photographers

Sirui has introduced two new wide-angle prime lenses for full-frame mirrorless cameras, expanding the focal range of its Aurora series. The 15mm f/1.6 and 24mm f/1.4 lenses join the existing 35mm and 85mm f/1.4 offerings. The 15mm focal length provides an ultra-wide perspective suitable for sweeping landscapes, interiors, and architecture. Meanwhile, the 24mm lens offers a versatile wide-angle view, ideal for environmental portraits.

Key features of the 24mm f/1.4 lens include an AF-S button, AF/MF switch, iris lock button, and click-on/off button. It consists of 14 elements in 11 groups, with 3 aspherical, 4 ED, and 3 HRI elements. The lens has a minimum focusing distance of 0.26m and weighs 550g. With 11 rounded aperture blades, it creates smooth out-of-focus areas and rounded bokeh at the widest aperture setting.

The lens is designed to minimize lens distortion and focus breathing, featuring special aspherical, extra-low dispersion, and high-refractive-index elements.

Both lenses also incorporate a de-click switch for the aperture ring, beneficial for video recording. They are equipped with STM stepping motors for silent focusing and support cameras with focus tracking and eye/face detection. Despite their robust all-metal construction, the lenses remain relatively lightweight at around 550g. Their weather-resistant bodies include a scaled aperture ring, focusing ring, Iris Lock, AF/MF switch, and a customisable FN function button.

Pre-orders for the lenses are now available in Sony E and Leica L mounts on Sirui's online store. The Aurora 15mm F1.6 is priced at $599/£529, while the Aurora 24mm F1.4 is available for $499/£439. Additionally, Fujifilm X and Nikon Z mount versions are expected to launch in early 2027.
