The Laowa 15mm F2 Zero-D from Venus Optics is a fast, wide prime lens for full frame mirrorless cameras, available in RF-mount, E-mount, and Z-mount. Like Lawoa's other 'Zero-D' lenses it's designed to have extremely limited distortion despite the short focal length.

We've included a number of images representing two common use cases for this type of lens: astrophotography and architectural photography. Overall, it provides excellent results and delivers on its promise of minimal distortion. Not surprisingly, there's some vignetting wide open, but it clears up pretty quickly when stopped down and – if desired – is corrected quite well using the lens profile in Adobe Camera Raw.

To illustrate the point, here's an uncorrected sequence of dark sky photos shot at F2, F2.8, F4 and F5.6. The original Raw files for these images can be downloaded from the sample gallery if you want to make your own comparisons. Click through to the gallery to see all the images.
