About This LensThis Panasonic prime fits the Micro Four Thirds mount and gives a wide 14mm view on that format. Panasonic released this second version in 2014, so it is an older design. That framing suits street photography, travel, interiors and landscapes, where context matters more than tight isolation. The size and weight suit anyone who wants a camera that is always ready. The main trade-off is the fixed focal length. You compose by moving closer or stepping back, not by zooming. That pace suits street and travel shooting, where you are already moving. In exchange, the body stays extremely small and light. | |

About the OpticsThe 14mm focal length gives a wide view rather than an extreme one, so buildings, streets and open landscapes fit without stepping far back. Near objects appear large while distant ones stay small in the same frame, which gives street pictures a sense of place. It works well as a walking-around lens for city photography. The f/2.5 maximum aperture is moderate for a wide prime. It gathers enough light for dim interiors, restaurants and evening streets while keeping the ISO low. It will not blur a background strongly, though. At this focal length depth of field runs deep, so most of the scene stays sharp at once. Close focus sits at 0.6 ft (18 cm). You can place a foreground detail near the camera and keep the wider scene behind it. That suits layered street frames and small rooms, where near objects give the picture depth. Fixed framing also builds habit. The view is always the same, so you learn where to stand before raising the camera. That habit suits documentary work, where reacting quickly matters more than framing choices. The optics specification scores 77. | |

About the FeaturesThe lens has no built-in image stabilisation. Any stabilisation must come from the camera body instead. Wide 14mm framing also reveals camera shake less than longer focal lengths would, which partly offsets the gap for handheld work. There is no weather sealing, so the lens suits dry street and travel days better than rain, sea spray or heavy dust. Treat damp conditions as a reason to stop and shelter the camera. The lens has no fluorine coating on the front glass. A 46mm protective filter can shield the glass in daily use. | |
Weather Sealing ⓘWeather sealing capabilities will give you more confidence when shooting in unfavourable conditions. | No |
Fluorine Coating ⓘCoating to repel water and oil from lens elements. | No |
| Built In Lens Hood | No |
Teleconverter ⓘA teleconverter (extender) is an extra piece of equipment that fits between the lens and the camera body to enhance magnification | No |
| Image Stabilization | No |
Construction38/100 | |
About the ConstructionSix elements in five groups include three aspherical elements. Aspherical surfaces are specially shaped to help correct optical faults, including distortion and spherical aberration. Distortion can make straight edges appear curved, which matters when buildings and door frames fill a wide frame. The simple layout suits such a short body. The construction specification scores 38. | |

Aspherical Elements ⓘThe number of aspherical lens elements which can help correct aberrations such as spherical aberration. | 3 |
Bi Aspherical Elements ⓘElements with two non-spherical surfaces | 0 |
Low Dispersion ⓘElements that reduce chromatic aberration | 0 |
Super Low Dispersion ⓘAdvanced elements further reducing chromatic aberration | 0 |
CA Reduction ⓘBuilt-in features to reduce chromatic aberration | 0 |
Internal Focusing ⓘInternal Focusing means that the lens does not change in size during focusing, and the front element does not rotate. | |
