Panasonic LUMIX G Lens
Score: 60/100
Sigma 16mm f/1.4 DC DN
Score: 83/100Rankings
The Sigma 16mm f/1.4 Contemporary delivers outstanding sharpness and a very fast aperture in a weather-sealed, compact package, making it a strong choice for APS-C shooters. Its lack of stabilization and some barrel distortion are the primary compromises.
The Panasonic LUMIX G 25mm f/1.7 ASPH is a compact, fast-aperture prime that delivers sharp images and quiet AF, making it a strong value for Micro Four Thirds shooters. Its lack of IS and weather sealing keep it from harsher environments, but its portability and price are hard to beat.
