Panasonic LUMIX G 25mm
Score: 79/100
Sigma 16mm f.4
Score: 82/100Rankings
The Sigma 16mm f/1.4 DC DN Contemporary offers a fast 16 mm focal length with excellent low-light capability and quiet stepping AF. Corner softness at the widest aperture and its relatively large size are trade-offs. Perfect for Sony APS-C shooters needing a bright wide-angle prime for street and video work.
The Panasonic LUMIX G 25mm f/1.7 ASPH is an ultra-compact, fast-aperture prime that delivers sharp images and quiet autofocus. It lacks weather sealing, image stabilization, and its corner performance drops at the widest aperture. Ideal for street, portrait and low-light shooters who prioritize size and speed over ruggedness.

Professional reviewers praise the lens for its delightfully lightweight and well-built feel, fast f/1.7 aperture, and quiet stepping-motor autofocus that suits both stills and video. They also note the high-quality aspherical/UHR optics that keep aberrations low. However, they criticize the lack of weather sealing, image stabilization, and the soft corner performance at the widest aperture, as well as the absence of a mechanical focus coupling.
Everyday users love how portable and light the lens feels, often describing it as "pancake-like" and "so light… not even perceive the extra weight." They appreciate the fast aperture for indoor and low-light shooting and the quiet AF for video. Common complaints focus on its fragility without weather sealing, occasional flare, and the inability to focus closely for macro work.
Professional reviewers commend the Sigma 16mm f/1.4 for its impressive center sharpness, bright aperture and quiet stepping AF, calling it a high-value option for Sony APS-C shooters. They note that while the lens excels in low-light and offers smooth bokeh, its corner performance at f/1.4 and occasional AF hunting in dim conditions are drawbacks, though in-camera distortion correction mitigates barrel distortion.
Everyday users generally praise the lens for its sharp images, pleasing bokeh, compact build and reliable AF in good light, appreciating the weather-sealed design for outdoor use. Recurring complaints focus on soft corners when wide open, AF inconsistency in low-light or close-up scenarios, and the lens being a bit bulkier than ultra-compact alternatives.
