Laowa 60mm f/2.8 Macro 2:1 Lens (Pentax) features a magnification range from 0.1x to 2x. Users could easily alter the magnification ratio without installing any extension tube or teleconverter. Ideally suited for rapidly changing macro photography scenes. This wide magnification range also makes it extremely useful for shooting macro objects (e.g. insects) with different sizes. Moreover, the lens is also designed for normal shooting purposes with a 60mm focal length, which provides an all-in-one solution for normal portrait as well as ultra-macro photography. The lens has 9 elements in 7 groups to provide great image clarity and colour and contrast. The Laowa consists of two major moving lens groups in order to minimize barrel distortion. Fourteen blade aperture renders a beautiful near-circular, creamy bokeh. Manual focus only, full frame (Macro shooting only, normal mode will slightly vignette) or APS-C (Macro or normal photography) compatible lens with a metal construction.Pentax mount. Accepts 62mm filters.
