At the 2018 Photokina show Venus Optics announced their new Laowa 10-18mm f/4.5-5.6 mirrorless lens:
“Designed primarily for travel photography, Venus optics have managed to compress the size to smallest in its class, less than 10 inch (<10cm) and only 1.1 pounds (<500g). The 102° (18mm) to 130° (10mm) angle of view provides flexibility for photographers to compose landscape or architecture photos with ease. The lens houses with 14 elements in 10 groups with 2 aspherical elements & 1 extra-low dispersion element to deliver exceptional performance. It can focus as close as 15cm for some mini-macro shooting. A rear filter slot is included to fit with 37mm filter. Click/clickless aperture can be toggled by the switch on the lens barrel.”
