Sirui’s Aurora 15mm f/1.6 and 24mm f/1.4 are up for pre-order at $599 and $499. Both full-frame autofocus primes fit Sony E and L-mount, with X and Z coming next year.
Sirui has opened pre-orders on two new wide-angle lenses for its Aurora full-frame autofocus series: a 15mm f/1.6 at $599 and a 24mm f/1.4 at $499, now the cheapest lens in the Aurora range. These sit alongside the existing 85mm f/1.4 and 35mm f/1.4, and take the Aurora line wider than it has gone before.
Both are available initially in Sony E and L-mount versions, with Nikon Z and Fujifilm X versions due at the start of next year.
It's been a short journey to market since pre-production samples were shown at IBC. The 15mm uses 17 elements in 12 groups, including three aspherical, three ED, and three HRI elements, and covers a 109.3° diagonal angle of view on full frame. Minimum focus is 0.3 m (0.98 ft), and unusually for an ultra-wide it takes screw-in filters via a 77mm front thread. It weighs 542 g (1.19 lb) in E-mount and 550 g (1.21 lb) in L-mount, and measures around 106 mm (4.2 in) long.
The 24mm f/1.4 is built from 14 elements in 11 groups, with three aspherical, four ED, and three HRI elements. It focuses down to 0.26 m (0.85 ft) for a maximum magnification of 0.15x, takes 62mm filters, and weighs 550 g (1.21 lb) in E-mount or 560 g (1.23 lb) in L-mount.
Both lenses use an STM stepping motor for autofocus, and Sirui says they work with the eye detection and subject tracking of compatible cameras. Each has an 11-blade aperture, a dust-, stain-, and splash-resistant all-metal body, and a USB-C port for firmware updates.
The control set leans toward video. The aperture ring can be switched between clicked and de-clicked operation, an iris lock holds it in the A or manual position, and there is an AF/MF switch plus a customizable Fn button that defaults to AF lock. Sirui pitches both lenses at gimbal and handheld work, and claims focus breathing is low.
Pre-orders are open now with the lenses due to shop around November 16.
