Laowa 15mm f/4 1:1 Wide Angle Macro Lens for Pentax K

Laowa 15mm f/4 1:1 Wide Angle Macro Lens for Pentax K

The Laowa 15mm f/4 Macro is the first wide-angle lens with 1:1 maximum magnification, opening up wide-angle macro photography without extension tubes. Macro lenses usually have medium to long focal lengths, which leave little room for the environment around flowers or insects; with a 110° angle of view at 1:1 the foreground dominates the frame while the background shows where and how the subject lives. This version has the Pentax K mount.

It also works as an excellent wide angle focusing to infinity on full-frame cameras. A shift mechanism at the rear offers ±6 mm adjustment (for APS-C sensors), useful in architecture and landscape photography to correct perspective. The 12 elements in 9 groups, with 3 high-refraction elements and one low-dispersion element, reduce chromatic aberration and ghosting for clarity from centre to edge, with controlled distortion. Low-reflection multi-layer coating, 14-blade aperture, manual focus and aperture.
