Panasonic LUMIX G Lens
Score: 60/100
Sigma 30mm f/1.4 DC DN
Score: 78/100Rankings
The Sigma 30mm f/1.4 Contemporary delivers a bright aperture, excellent sharpness and quiet autofocus in a compact package for Sony APS-C bodies. It lacks weather sealing and built-in stabilization, and its focal length is fixed at a 45 mm equivalent, which may limit versatility.
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.
