About This LensThis 2024 Panasonic zoom gives Leica L mount photographers a single lens for full-frame travel and everyday shooting. The 28–200mm span opens wide enough for street scenes and interiors, then reaches far enough for portraits and distant landmarks. It suits anyone who wants to travel with one body and one lens. Panasonic still builds it, so this is a current design rather than an older model. The trade-off is light gathering. The maximum aperture falls from f/4 at 28mm to f/7.1 at 200mm, which favours daylight work over dim interiors and evening streets. | |

About the BuildAt 14.6 oz (413 g), the lens is light for a 28–200mm zoom and stays comfortable across a long walking day. The body measures 3.68 in (93.4 mm) long and 3.04 in (77.3 mm) wide. A screw-in filter must match the 67mm thread on the front. | |

About the OpticsThe zoom range handles most framing decisions without a lens change. At 28mm, it takes in markets, interiors and wide views. At 200mm, it makes distant subjects larger, so compressed portraits and animals across a field stay in reach. A rotary ring controls the zoom by hand. Light handling depends on where you set the zoom. The f/4 maximum at 28mm manages overcast days and shaded rooms. Zoomed to 200mm, f/7.1 needs brighter light or a higher ISO, and evening city work will push settings up. Depth of field also runs deep at that end, so busy backgrounds stay prominent. The Macro name needs one caveat. This lens reaches 0.5x magnification, half life-size rather than the 1:1 of a true macro lens. That still fills the frame with flowers, food or campsite details on a trip. Close focusing down to 0.5 ft (14 cm) also helps with small subjects. A nine-blade diaphragm helps the aperture close in a rounder shape, which tends to smooth out-of-focus highlights. Our optics score for this lens is 56. | |

Features81/100 | |
About the FeaturesOptical image stabilisation steadies the camera for handheld frames at slower shutter speeds. That helps most at 200mm, where small hand movements show clearly in the frame. The stabiliser counteracts your own shake; it does not freeze a moving subject such as a bird in flight. On a tripod the stabiliser matters less. Weather sealing keeps dust and moisture away from the internals, useful when travel takes you into rain or sea spray. A fluorine coating on the front helps water and oil slide off, so the glass wipes clean quickly between shots. There is no zoom lock switch. Our features score for this lens is 81. | |

Zoom Lock ⓘZoom lock allows the zoom ring to be locked at the desired focal length | 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 | Yes |
IS Efficiency ⓘIS efficiency refers to the effectiveness of the image stabilization system in compensating for the blurring effects of camera shake, quantified by the number of stops of stabilization it provides. | 6.5 stops |
Construction69/100 | |
About the ConstructionFocusing moves elements inside the barrel, so the lens keeps its length while you focus. That helps when you work close to a subject, because the front does not extend toward it. Four low-dispersion elements help reduce chromatic aberration, the coloured fringes that can trace high-contrast edges at the 200mm end. One aspherical element helps correct distortion, the fault that can bend straight edges at the wide end. | |
Elements ⓘLens elements refer to individual pieces of glass within the lens. | 17 |

Aspherical Elements ⓘThe number of aspherical lens elements which can help correct aberrations such as spherical aberration. | 1 |

Low Dispersion ⓘElements that reduce chromatic aberration | 4 |
Super Low Dispersion ⓘAdvanced elements further reducing chromatic aberration | 0 |
CA Reduction ⓘBuilt-in features to reduce chromatic aberration | 1 |
Internal Focusing ⓘInternal Focusing means that the lens does not change in size during focusing, and the front element does not rotate. | |
