Laowa Venus Optics 10mm f/2.8 Zero-D FF Auto Focus for Sony E is an ultra-wide-angle prime lens designed for full-frame mirrorless cameras with Sony E mount. The 10 mm focal length provides a 130.4° angle of view, making it suitable for landscape photography, architecture, interiors, astrophotography, travel, real estate, and creative shooting where a very wide portion of the scene needs to be included. The Zero-D designation refers to a rectilinear design focused on controlling distortion, a useful feature especially when photographing architectural lines, interiors, or subjects with evident geometric shapes. The f/2.8 maximum aperture allows shooting in lower-light conditions and makes the lens interesting for night photography and astrophotography. The optical design consists of 15 elements in 9 groups, with 2 aspherical elements and 3 ED elements, intended to limit chromatic aberrations and loss of sharpness. The Sony E version integrates autofocus, with a 5-blade diaphragm, a minimum focusing distance of 12 cm, and a maximum magnification ratio of 0.24x, useful for close compositions with an ultra-wide perspective. The lens accepts 77 mm front filters, a practical feature compared with many ultra-wide lenses with protruding front elements, and maintains compact dimensions with a weight of approximately 420 g. Laowa 10mm f/2.8 Zero-D FF AF for Sony E is suitable for photographers and videographers looking for an extreme full-frame wide-angle lens that is compact, bright, and equipped with autofocus, with particular attention to distortion control and the possibility of using standard circular filters.
