The best lenses for Panasonic Lumix G9 II pair its Micro Four Thirds mount with the kind of focal length you actually shoot. For this roundup, I narrowed the choices to eight native OM SYSTEM / Olympus M.Zuiko lenses, covering a daily standard zoom, a weather-sealed telephoto, fast primes, macro work, and light travel kits.
One correction matters before choosing: the Lumix G9 II is a Micro Four Thirds camera, not an L-mount camera. Each lens below mounts directly, with no adapter, and the listed 35mm-equivalent fields of view help translate the smaller-format focal lengths into familiar terms.
I would start with the 12-40mm F2.8 PRO II for an all-weather standard zoom, or the 25mm F1.8 II when compact, bright everyday shooting matters more than zooming. Wildlife photographers should look first at the 40-150mm F4 PRO; it reaches a 300mm equivalent field of view while remaining a comparatively compact option.
Ratings and specifications below come from the supplied product records, not imagined field tests. That distinction is useful: a lens can be a strong match on paper, but your subject distance, light, bag space, and need for weather protection should make the final call.
The top 3 picks give most G9 II owners a clear starting point (August 2026)
The PRO 12-40mm is the all-round choice because it combines a 24-80mm equivalent range with a constant f/2.8 aperture and IP53 weather sealing. The 25mm F1.8 II is the simpler everyday prime, while the 40-150mm F4 PRO gives outdoor and field-sport shooters useful reach with a constant aperture.
These eight Micro Four Thirds lenses cover the G9 II in 2026
Think of this overview as a short route to the right focal range. A 12-45mm or 12-40mm covers most trips and family work, 40-150mm options cover distant action, and the primes bring brighter apertures for lower light and more background separation.

1. The OM SYSTEM M.Zuiko 12-45mm F4 PRO is the compact everyday standard zoom
OM SYSTEM Olympus M.Zuiko Digital ED 12-45mm F4.0 PRO for Micro Four Thirds System Camera, Compact Lightweight Zoom, Weather Sealed Design, Close-up, L-Fn Button
12-45mm
24-90mm equivalent
f/4
IPX1 sealed
Pros
- 24-90mm equivalent range
- Constant f/4
- IPX1 weather sealing
- 0.12m close focus
- 58mm filter
Cons
- No supplied optical stabilization
- Less light than f/2.8 zooms
This is the lens I would choose for a one-lens walking kit when 24-90mm equivalent coverage matters more than a very bright aperture. It spans landscapes at the wide end, environmental portraits in the middle, and modest telephoto framing without changing lenses.
The supplied specifications list a constant f/4 aperture, a 58mm filter thread, and a 0.12m minimum focus distance. That close-focus figure gives it a practical edge for food, flowers, and detail shots on a trip, even though it is not a dedicated macro lens.
Its 16-ounce weight and IPX1 weather-sealed construction point to a small, outdoor-ready pairing for the G9 II. The product record also lists high-speed focusing and a programmable L-Fn button, two welcome controls when moving quickly between scenes.
The 12-45mm F4 PRO fits travel photographers who need one compact lens
Choose it if you want a native Micro Four Thirds zoom that begins at a 24mm equivalent view but still reaches a 90mm equivalent portrait-friendly framing. It is particularly sensible for hikes and city days where a larger two-lens kit would stay in the bag.
The fixed f/4 maximum keeps exposure behavior predictable as you zoom. In dim interiors or after sunset, the brighter 12-40mm F2.8 PRO II and fast primes are the better matches.
The 12-45mm F4 PRO needs the G9 II body stabilization rather than lens stabilization
The product data lists digital image stabilization rather than an optical stabilizer in the lens. The G9 II’s in-body stabilization is therefore the important support for hand-held stills and calmer video.
Focus stacking is listed as available when paired with a compatible camera, so confirm the relevant camera function before planning a stacked close-up sequence. Its strength is flexible close work, not a stated 1:1 magnification ratio.
2. The OM SYSTEM M.Zuiko 40-150mm F4 PRO is the weather-sealed telephoto choice
OM SYSTEM Olympus M.Zuiko Digital ED 40-150mm F4.0 PRO for Micro Four Thirds System Camera Compact Powerful Zoom Weather Sealed Design Fluorine Coating
40-150mm
80-300mm equivalent
f/4
IP53 sealed
Pros
- 80-300mm equivalent
- Constant f/4
- IP53 sealing
- MF clutch
- Fluorine coating
Cons
- No supplied optical stabilization
- Does not reach super-telephoto fields
The 40-150mm F4 PRO is the strongest fit here for wildlife at moderate distances, outdoor portraits, and field sports where a 300mm equivalent long end is enough. Its constant f/4 aperture is more predictable than the variable-aperture budget option.
At 381 grams, it is a manageable size for a G9 II kit, and the supplied data gives it a 62mm filter thread. A 0.7m minimum focusing distance and 0.41x maximum image magnification also make it more useful for larger flowers and details than its telephoto label suggests.
OM SYSTEM lists IP53 weather sealing and a fluorine coating, which are meaningful distinctions for photographers who work around spray, dust, or changing weather. The manual-focus clutch adds a direct control point for deliberate focus adjustments.
The 40-150mm F4 PRO suits birds, sports, and distant portrait work
Its 80-300mm equivalent range puts more reach in a small bag than a standard zoom can offer. I would see it as a sensible first telephoto for subjects that are far away but not at the extreme distances common in small-bird photography.
Forum discussions consistently flag reach and weather protection as priority concerns for G9 II wildlife users. This lens directly answers the second concern and gives useful reach, but it has no stated compatibility with teleconverters in the supplied record.
The 40-150mm F4 PRO rewards photographers who value a constant aperture
Keeping f/4 available throughout the zoom range makes manual exposure and video adjustments less disruptive. That is especially helpful when a subject moves from the short end toward the long end during a sequence.
The product record describes digital rather than optical stabilization. Plan to rely on the camera’s in-body system, and use shutter speeds appropriate for motion when photographing active wildlife.
3. The OM SYSTEM M.Zuiko 20mm F1.4 PRO is the fast prime for daily low-light work
OM SYSTEM Olympus M.Zuiko Digital ED 20mm F1.4 PRO Lens,Black
20mm
40mm equivalent
f/1.4
247g
Pros
- Fast f/1.4 aperture
- 40mm equivalent
- Weather-resistant build
- MF clutch
- 58mm filter
Cons
- Fixed focal length
- No supplied optical stabilization
The 20mm F1.4 PRO gives the G9 II a 40mm equivalent view that sits between a classic wide normal and a 50mm normal lens. I would pick it for street work, food, informal portraits, and indoor scenes where stepping closer or farther away is practical.
Its f/1.4 maximum aperture is the main reason to choose it over a compact zoom. It allows more light to reach the sensor and gives greater potential for background separation than an f/4 zoom at a similar angle of view.
The record lists a 247-gram weight, 58mm filter size, fluorine coating, and an MF clutch. Those details make this a more purposeful prime than a pancake: it remains portable, but its controls and weather-resistant design speak to regular outdoor use.
The 20mm F1.4 PRO works for photographers who prefer one natural-looking field of view
A 40mm equivalent view is wide enough to show context but narrow enough to avoid the exaggerated perspective of an ultra-wide lens. It suits travel stories and candid people pictures when you want to stay close to the scene.
It is also a good answer for G9 II owners who find the camera body feels awkward with a very tiny lens. At 247 grams, this prime should give the grip a more settled pairing without becoming a large lens.
The 20mm F1.4 PRO asks photographers to frame with their feet
There is no zoom range to rescue a distant subject or rapidly tighten a composition. Pick it when you can commit to the 40mm equivalent viewpoint rather than when event coverage requires frequent framing changes.
The supplied data lists digital image stabilization and does not list optical lens stabilization. The G9 II body remains the stabilization source, while the f/1.4 aperture helps when available light falls.
4. The OM SYSTEM M.Zuiko 60mm F2.8 Macro is the dedicated close-up lens
OM SYSTEM Olympus M.Zuiko Digital ED 60mm F2.8 Macro for Micro Four Thirds System Camera, Weather Sealed Design, Focus Limit Switch Bright
60mm macro
120mm equivalent
f/2.8
1:1 magnification
Pros
- 1:1 life-size macro
- 0.19m close focus
- Focus limiter
- IPX1 splashproof
- Working distance window
Cons
- Fixed focal length
- No lens stabilization
The 60mm F2.8 Macro is the right specialized choice when the subject is a watch, insect, flower, texture, or product detail rather than a distant scene. Its 60mm focal length becomes a 120mm equivalent field of view, giving you useful working distance around small subjects.
The key specification is 1:1 life-size magnification at a 0.19m minimum focusing distance. That makes it the only lens in this group explicitly built for true macro reproduction rather than merely close focusing.
The 185-gram lens includes a focus-limit switch and a working-distance window according to the product data. Those controls can reduce focus hunting and make it easier to judge your setup when working near the minimum distance.
The 60mm F2.8 Macro suits close-up photographers who need true life-size magnification
Choose it when the detail itself must fill the frame, because 1:1 magnification is a different capability from the 0.41x maximum listed for the 40-150mm F4 PRO. The longer 120mm equivalent view also helps avoid putting the camera directly over a shy subject.
Its f/2.8 aperture can support portraits as well, though a macro lens is best bought for the close-focus task first. The 46mm filter size keeps filtration compact if you use protective or creative filters.
The 60mm F2.8 Macro requires steady technique at high magnification
The specification list says the lens has no image stabilization. The G9 II’s in-body stabilization can help, but subject movement and the very shallow depth of field at close range still call for careful camera position and thoughtful aperture selection.
IPX1 splashproof construction and ZERO coating add reassurance for outdoor close-up work. They do not replace basic care when working around sustained rain, sand, or salt spray.
5. The OM SYSTEM M.Zuiko 25mm F1.8 II is the simple normal prime for everyday photography
OM SYSTEM Olympus M.Zuiko Digital 25mm F1.8 II for Micro Four Thirds System Camera, Weather Proof, Compact Design, Beautiful Bokeh, Bright
25mm
50mm equivalent
f/1.8
156g
Pros
- 50mm equivalent
- f/1.8 aperture
- 156g weight
- IPX1 weatherproof
- 0.25m close focus
Cons
- Fixed focal length
- No supplied optical stabilization
The 25mm F1.8 II is the most straightforward normal prime in this list: its 50mm equivalent view works for people, everyday scenes, casual portraits, and travel. It is a sensible way to add a bright lens without turning the G9 II into a large kit.
At 156 grams, it is lighter than the 20mm F1.4 PRO, and the f/1.8 aperture provides a clear light-gathering advantage over the compact zooms. The 0.25m minimum focus distance also lets you frame small objects and food without backing far away.
The supplied specifications include an IPX1 weatherproof rating, metal body, 46mm filter thread, and seven-blade circular aperture. That combination gives the lens a practical daily-use identity rather than treating it as an indoor-only budget prime.
The 25mm F1.8 II fits G9 II owners who want a first bright prime
If you have only used a kit zoom, this 50mm equivalent view teaches fast, simple composition without feeling unusually wide or tight. It is the lens I would point beginners toward when they want more low-light flexibility and bokeh from one fixed focal length.
The product data calls out beautiful bokeh, but background blur depends on focus distance and the background itself. Get physically closer to your subject and keep the background farther behind it for the strongest separation.
The 25mm F1.8 II works best when its fixed 50mm-equivalent view matches your subjects
A normal prime is less convenient for distant wildlife and broad interiors than a zoom. It shines when you can move, anticipate a scene, and accept that changing focal length means changing your position.
There is no optical stabilizer listed in the product record, so hand-held steadiness comes from the G9 II. The small 46mm filter size is an added practical benefit if you already use compact filters.
6. The OM SYSTEM M.Zuiko 12-40mm F2.8 PRO II is the professional standard zoom
OM SYSTEM Olympus M.Zuiko Digital ED 12-40mm F2.8 PRO II for Micro Four Thirds System Camera Weather Sealed Design Fluorine Coating MF Clutch Compact Zoom Lens
12-40mm
24-80mm equivalent
constant f/2.8
IP53
Pros
- Constant f/2.8
- 24-80mm equivalent
- IP53 sealing
- MF clutch
- Fluorine coating
Cons
- 381g weight
- No lens stabilization
The 12-40mm F2.8 PRO II is the best standard zoom lens for Panasonic G9 II owners who need a dependable 24-80mm equivalent range and a constant bright aperture. It covers a wide environmental frame through a short telephoto portrait view without a lens change.
Its f/2.8 aperture stays constant through the entire 3.3x zoom range, which is helpful for consistent exposure and subject separation. It also gives a full stop more light than an f/4 zoom, a useful difference for indoor stills and low-light video.
The 381-gram weight is not the lightest option, but it gives the G9 II a more substantial pairing than a pancake lens. The supplied record lists IP53 weather sealing, a fluorine coating, 62mm filters, and an MF clutch for direct manual-focus control.
The 12-40mm F2.8 PRO II fits hybrid shooters who need one serious standard zoom
It is a strong selection for events, travel, documentary work, and general video because the 24-80mm equivalent range handles many common compositions. A constant f/2.8 aperture also keeps your exposure from shifting simply because you zoomed.
Forum users often recommend professional 12-35mm-class f/2.8 zooms for G9 II bodies. This 12-40mm option follows the same practical logic while giving an 80mm equivalent long end in the supplied specification.
The 12-40mm F2.8 PRO II favors capability over the smallest possible bag
At 381 grams, it is substantially heavier than the 156-gram 25mm F1.8 II and the 93-gram 14-42mm EZ. Choose it when speed, sealing, and a consistent aperture outweigh the appeal of a near-pocketable setup.
No optical stabilization is listed, so the body is responsible for stabilized hand-held work. The weather-resistant construction is the more decisive reason to prefer it for wet or dusty assignments.
7. The OM SYSTEM M.Zuiko 40-150mm F4-5.6 R is the budget telephoto for daylight reach
OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R Silver for Micro Four Thirds System Camera, 3.75x Zoom Lens, Portable Design
40-150mm
80-300mm equivalent
f/4-5.6
3.75x zoom
Pros
- 80-300mm equivalent
- Portable design
- 3.75x zoom
- MSC autofocus
- 0.16x magnification
Cons
- Variable f/4-5.6 aperture
- No stabilization
- Not weather resistant
The 40-150mm F4-5.6 R gives a G9 II owner the same 80-300mm equivalent framing territory as the F4 PRO version, but with a variable aperture and fewer outdoor protections. It is the logical budget lens for distant daylight subjects, school events, and occasional telephoto use.
Its 3.75x zoom range is broad enough to move from a medium telephoto composition to a tighter frame without swapping lenses. The product record lists High-Speed Imager AF with MSC, a feature worth noting for photographers who want a portable telephoto with autofocus support.
The specification set lists 10.24 ounces, no optical image stabilization, and no water resistance. Those are clear trade-offs rather than hidden fine print, and they help separate this lens from the F4 PRO option.
The 40-150mm F4-5.6 R suits daylight telephoto shooters on a tighter kit plan
Its long end reaches a 300mm equivalent field of view, which can make portraits, distant architecture, and sideline action more accessible than any standard zoom. I would use it where good daylight lets its f/4-5.6 aperture work comfortably.
The maximum 0.16x image magnification is modest, so it should not replace a macro lens. It is designed around convenient reach, not close-up reproduction.
The 40-150mm F4-5.6 R needs protection from difficult weather and fading light
The product data explicitly says it is not water resistant, so it is not the pick for exposed wet-weather work. The variable aperture also becomes f/5.6 at the telephoto end, where active subjects may demand higher ISO or more light.
Its lack of stated lens stabilization makes the G9 II’s in-body stabilization useful for static subjects. For moving wildlife or sports, use a shutter speed based on subject movement rather than expecting stabilization to freeze action.
8. The OM SYSTEM M.Zuiko 14-42mm F3.5-5.6 EZ is the retractable travel and video zoom
OM SYSTEM Olympus M.Zuiko Digital 14-42mm F3.5-5.6 EZ Silver for Micro Four Thirds System Camera, Compact 3X Zoom Lens
14-42mm
28-84mm equivalent
retractable
electric zoom
Pros
- Retractable pancake design
- 28-84mm equivalent
- Electric zoom
- Quiet MSC autofocus
- 0.2m close focus
Cons
- Variable f/3.5-5.6 aperture
- No stabilization
- Not weather resistant
The 14-42mm F3.5-5.6 EZ is the travel-focused choice for G9 II owners who want a small standard zoom and electronic zoom control. Its 28-84mm equivalent range covers the familiar wide-to-short-telephoto span for vacations, everyday recording, and casual photography.
The retractable pancake design is the main attraction, and the supplied product title lists a 93-gram weight. That makes it dramatically lighter than the PRO standard zooms and can be the difference between packing the camera and leaving it behind.
The data also lists electric zoom, wireless zoom control, a rotating focus ring, quiet MSC autofocus, and 0.2m close focusing. Those functions make it the most video-oriented compact lens in this group, provided you accept its variable aperture.
The 14-42mm EZ fits travelers and video creators who put size first
The electronic zoom is useful when a smooth, controlled framing change is preferable to twisting a manual zoom ring. The 28-84mm equivalent range is also a comfortable everyday span for travel clips and family scenes.
This is a particularly sensible option if the G9 II is not your only camera and you need it to fit into a small day bag. Its range is more general-purpose than the fixed 25mm or 20mm primes.
The 14-42mm EZ works best in favorable light and dry conditions
The product record lists an f/3.5-5.6 variable aperture, no image stabilization, and no water resistance. That means it is not the first choice for rain, dim reception rooms, or a shallow-depth-of-field look.
Use the G9 II’s stabilization for static hand-held shots, but recognize that the lens’s small size is the central benefit. Photographers who need weather sealing or a constant aperture should move up to either PRO standard zoom.
The right G9 II lens choice starts with the subjects you photograph
Start by matching the field of view to your normal shooting distance. A 12-40mm or 12-45mm standard zoom handles travel, family, and landscape work; a 40-150mm telephoto changes how close you can frame wildlife and action; a prime works when you want a brighter aperture and can move your feet.
A Micro Four Thirds lens mounts directly on the Lumix G9 II
Every lens in this article is specified for the Micro Four Thirds mount, so each is directly compatible with the Panasonic Lumix G9 II. Do not buy an L-mount lens for this body on the assumption that it will attach without an adapter; it will not.
The smaller sensor format gives a two-times full-frame-equivalent angle of view. In practical terms, 12mm frames like 24mm, 25mm frames like 50mm, and 150mm frames like 300mm, as reflected in the supplied lens records.
A constant aperture helps when exposure consistency matters
The 12-40mm F2.8 PRO II, 12-45mm F4 PRO, and 40-150mm F4 PRO keep the same maximum aperture throughout their zoom ranges. That makes exposure planning easier and avoids losing light as you zoom toward a distant subject.
Variable-aperture zooms such as the 14-42mm EZ and 40-150mm R save size and weight, but their maximum aperture becomes smaller at the long end. They make the most sense for daylight, travel, and situations where compactness ranks above low-light flexibility.
Weather-sealed lenses help outdoor photographers work with more confidence
The supplied product data identifies the 12-40mm F2.8 PRO II and 40-150mm F4 PRO as IP53 weather-sealed, while the 12-45mm F4 PRO, 60mm Macro, and 25mm F1.8 II have IPX1 splash-related ratings. Those are better choices for outdoor users than the 40-150mm R and 14-42mm EZ, both listed as not water resistant.
Weather resistance describes a system of protection, not permission to ignore conditions. Protect the camera mount area, dry equipment after use, and treat standing water or salt spray as a separate risk.
In-body stabilization is important because these records do not list optical lens stabilization
The G9 II’s body stabilization is a practical benefit with these lenses because the provided records list either digital stabilization or no lens stabilization. It can steady static scenes and hand-held video, but it cannot stop a bird, athlete, or moving child.
For action, shutter speed remains the priority. For macro, stabilization helps camera movement but does not remove the shallow depth-of-field challenge at 1:1 magnification.
A simple two-lens kit covers most G9 II photography
I would build a versatile all-weather kit around the 12-40mm F2.8 PRO II and 40-150mm F4 PRO. Together their supplied equivalent ranges run from 24mm to 300mm, with a gap between 80mm and 80mm that is effectively none.
A lighter alternative is the 12-45mm F4 PRO plus the 40-150mm F4-5.6 R. Add the 25mm F1.8 II when you want a bright normal prime, or the 60mm Macro when close work is a genuine priority rather than an occasional experiment.
The answers below address the most common G9 II lens questions
What is the best standard zoom lens for Panasonic Lumix G9 II?
The OM SYSTEM M.Zuiko 12-40mm F2.8 PRO II is the best standard zoom in this group for demanding G9 II work because it covers a 24-80mm equivalent range, holds a constant f/2.8 aperture, and has IP53 weather sealing. Choose the 12-45mm F4 PRO instead when lighter carry weight and a longer 90mm equivalent reach matter more than f/2.8.
Which telephoto lens is recommended for wildlife photography on G9 II?
The OM SYSTEM M.Zuiko 40-150mm F4 PRO is the recommended telephoto here for wildlife because its 80-300mm equivalent range, constant f/4 aperture, IP53 weather sealing, and 381-gram weight balance reach and portability. The 40-150mm F4-5.6 R reaches the same 300mm equivalent view for occasional daylight use but is not weather resistant.
What prime lenses work well with the Panasonic G9 II?
The 20mm F1.4 PRO, 25mm F1.8 II, and 60mm F2.8 Macro all work directly on the G9 II because they use Micro Four Thirds. Pick the 20mm for a 40mm equivalent everyday view, the 25mm for a classic 50mm equivalent view, and the 60mm for 1:1 macro work with a 120mm equivalent field of view.
Is the Panasonic 12-60mm lens good for the G9 II?
A Panasonic 12-60mm Micro Four Thirds lens is directly compatible with the G9 II, but it is not one of the eight lenses reviewed here. For a similar all-purpose role from this selection, choose the OM SYSTEM 12-45mm F4 PRO for 24-90mm equivalent coverage and close focusing, or the 12-40mm F2.8 PRO II for a constant brighter aperture.
What is the best budget lens for Panasonic Lumix G9 II?
The OM SYSTEM M.Zuiko 25mm F1.8 II is the best budget-minded everyday pick in this group because it is a 156-gram, weatherproof 50mm-equivalent prime with an f/1.8 aperture. For budget-minded telephoto reach, the 40-150mm F4-5.6 R delivers an 80-300mm equivalent range but gives up weather resistance and a constant aperture.
The best overall choice is the lens that matches how you use the G9 II
For the most complete single-lens setup, choose the 12-40mm F2.8 PRO II. For a smaller standard zoom, choose the 12-45mm F4 PRO; for telephoto reach, choose the 40-150mm F4 PRO; and for a bright everyday prime, choose the 25mm F1.8 II.
The best lenses for Panasonic Lumix G9 II are all native Micro Four Thirds options in this guide, so compatibility is simple. Pick the focal range you will use most often, then decide whether aperture speed, weather protection, macro magnification, or the smallest possible carry size deserves priority in 2026.
