Laowa Venus Optics 15mm f/4 Macro Lens for Pentax K

Venus Optics is offering photographers the first native option to get started in the world of wide-angle macro photography with the Laowa 15mm f/4 Macro Lens, available here for full-frame Pentax K-mount cameras. Before now, wide-angle macro required the use of extension tubes and other workarounds, but now the Laowa 15mm Macro offers true 1:1 magnification without the hassle. The ultra-wide perspective on full-frame cameras allows users to get exceptionally close to their subjects with a minimum focus distance of just 4.7", and have them fill the frame, while still capturing the background for more informative scenes. Internal focusing further assists by not disturbing your subject, even when you reach the 0.2" minimum working distance.

Optically, it is designed to minimize distortion that plagues wide-angle lenses with the use of an advanced 12 element in 9 group construction with one extra-low dispersion and three high-refractive elements. A multi-layer low-reflective coating further improved image quality by reducing the appearance of flare and ghosting. Also, when used on APS-C cameras, or in crop modes, the lens offers +/- 6mm of vertical shift which can help correct for perspective when shooting objects such as buildings.

Full manual operation is required with this lens through the use of a physical aperture ring with a range of f/4 to f/32 and a large focusing ring. A flat front element provides room for a 77mm front filter thread for using a selection of specialized filters to enhance your scene. Additionally, it has a near-circular 14-blade diaphragm for smooth out of focus elements and comes with a lens hood.
