Chinese lens manufacturer Anhui ChangGeng Optical Technology Company Limited has introduced what it describes as the world's widest 1:1 macro lens. The Venus Optics Laowa 15mm F4 is designed for full frame sensor cameras and can focus down to just 12cm from the front element. As well as operating as a macro lens, the unit is equipped with a +/-6mm shift function for architectural work at normal focusing distances. Shift function is only available when shooting on APS-C crop sensors though.

Constructed using 12 elements in 9 groups, the 110° lens has a 14-blade aperture and will be made with mounts for Canon EF, Nikon F, Sony Alpha, Sony FE and Pentax K cameras. It weighs 410g/0.9lb, measures 83.8x64.7mm/3.3x2.5in and uses a 77mm filter.

Available now, the Laowa 15mm F4 Wide Angle 1:1 Macro Lens costs $479. For more information see the Venus Optics website.
