Panasonic LUMIX G Series LEICA 9mm f/1.7

This Panasonic prime gives Micro Four Thirds photographers an ultra-wide 9mm view. It suits architecture, tight interiors and sweeping landscapes. Travel and street shooters can also use it where a scene is too large for a normal lens.

The f/1.7 aperture lets in plenty of light for dim conditions. The main trade-off is the fixed focal length: you frame by moving yourself, because there is no zoom ring.

Panasonic launched this lens in 2022 for its LUMIX G system.

At 4.6 oz (130 g) and 2.05 in (52 mm) long, this lens adds almost nothing to a bag. On a small Micro Four Thirds body it will barely register. A screw-in filter must match the lens's 55mm thread, and this one takes filters directly, so polarisers and ND filters mount without adapters.

The 9mm focal length gives an extremely wide view on the Micro Four Thirds format. It pulls whole rooms, building facades and open skies into a single frame. Distant subjects look small at this width, so a strong foreground gives the frame impact. Getting close to that foreground element also exaggerates the sense of depth, which suits landscape and interior composition.

The f/1.7 maximum aperture suits handheld shooting in dim churches, dusk streets and evening interiors. The wide opening lets you use faster shutter speeds in that light, which reduces the risk of blur from camera shake. The seven blades help keep out-of-focus highlights round.

Focus as near as 0.3 ft (9.5 cm) lets you move right up to a subject. A rock, plant or interior detail can appear large while the wide view keeps its surroundings visible. Maximum magnification reaches 0.25x, which suits near-detail work on small objects.

In our specification assessment the optics scored 84. At this width, small shifts in camera position change the frame a great deal, so composition takes deliberate care.

The lens is sealed against dust and moisture, so light rain, sea spray and dusty trails are less likely to end a shoot. Wide landscape and travel work often happens in exactly those conditions, which makes the sealing the most useful feature here.

There is no stabilisation built in. At 9mm, camera shake affects handheld shots less than it would at longer focal lengths, so the loss is smaller for static scenes. There is also no fluorine coating, so the front glass has no layer designed to repel water and oil.

Our features score for this lens is 32.

Two aspherical elements help reduce distortion and spherical aberration. That correction matters at 9mm, because ultra-wide designs tend to bend straight edges, and architecture is a natural subject here. Two low-dispersion elements help reduce chromatic aberration, the coloured fringes that can appear along high-contrast edges such as backlit branches against sky. Focusing is internal, so the barrel does not extend as you focus.
