On the other hand, the Sigma 18-50mm F2.8 is designed for versatility with superb optical quality and in-camera aberration correction. Both lenses provide excellent image quality, but the Laowa's unique angle makes it particularly suited for wide-angle photography.
Minimum Focusing Distance
The Laowa 10mm f/2.8 Zero-D features a minimum focusing distance of just 12cm, allowing photographers to get exceptionally close to their subjects.
