Panasonic LUMIX G 25mm
Score: 79/100Rankings
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.
The Sigma 105mm f/2.8 EX DG OS HSM Macro is a full-frame medium-telephoto macro lens offering true 1:1 reproduction and optical stabilization. Its plasticky construction and diffraction at small apertures limit its premium appeal. Ideal for macro shooters seeking value and handheld capability.

Professional reviewers commend the Sigma 105mm f/2.8 macro for its excellent sharpness from wide open to f/11, effective optical stabilization, and true 1:1 reproduction, positioning it as a strong value proposition. However, they note its plasticky construction, diffraction-limited performance past f/8, and occasional low contrast or chromatic aberration when stopped down, which keep it a step behind premium Nikon and Canon counterparts in build quality and extreme stopped-down performance.
Everyday users overwhelmingly appreciate the lens's sharpness, reliable stabilization for handheld macro, quiet autofocus, and attractive bokeh, seeing it as a cost-effective macro solution. Common frustrations revolve around the plasticky feel, occasional focus hunting, and softness when stopping down beyond f/8, though most find these issues acceptable for the price.
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.
