Best Lenses for Panasonic G9 II in 2026

The table below shows all 12 recommended lenses with their key specifications to help you compare options quickly.

1. Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4.0

The Panasonic Leica DG Vario-Elmarit 12-60mm earns my top pick as the best all-around lens for the G9 II. I found it to be the workhorse lens that handles nearly anything you throw at it. The 24-120mm equivalent focal range covers standard zoom territory with enough reach for casual wildlife shots.

Image quality from this lens impressed me consistently. Leica branding is not just marketing here. The Nano Surface Coating minimizes flare effectively, and the 9 diaphragm blades produce pleasing bokeh when you shoot wide open. Colors render with natural contrast that suits both JPEG shooters and raw processors.

Autofocus performance stands out on the G9 II. The 240 fps linear motor locks focus quickly even in challenging lighting. When combined with the G9 II body, Dual I.S. 2.0 provides roughly 5 stops of stabilization, making handheld video smooth and low-light photography manageable without pushing ISO too high.

Build quality feels professional. The splashproof, dustproof, and freezeproof construction gives me confidence shooting in adverse conditions. At 1.3 pounds, it adds noticeable weight to the G9 II but remains balanced on the body.

Best For Travel Photographers

If you want one lens that handles diverse shooting scenarios without changing glass, this is it. The versatile zoom range means you can capture wide establishing shots, standard perspectives, and telephoto moments without swapping lenses. Travel photographers benefit most from this flexibility.

Considerations Before Buying

The variable aperture (f/2.8-4.0) limits low-light performance compared to constant f/2.8 zooms. If you frequently shoot indoors or in dark environments, pair this with a fast prime for those situations. Some users report receiving defective units, so purchase from reputable sellers with good return policies.

2. Olympus M.Zuiko Digital ED 40-150mm f/2.8 PRO

The Olympus 40-150mm f/2.8 PRO surprised me with how much professional performance fits into such a compact package. At 544 grams, this is a portable telephoto that delivers constant f/2.8 throughout its range. The 80-300mm equivalent focal length covers wildlife, sports, and portraits effectively.

Sharpness levels rival fixed focal length lenses. I tested this extensively on the G9 II and could not find meaningful softness even at 150mm wide open. Colors render with Olympus signature warmth, and the ZERO coating handles backlit situations gracefully.

The Dual VCM autofocus mechanism represents cutting-edge technology. Focus acquisition happens almost instantaneously on the G9 II, and the lens maintains tracking reliably for moving subjects. If you shoot wildlife or sports, this autofocus performance matters significantly.

Weather sealing provides peace of mind for outdoor sessions. I used this in light rain without issues, and the fluorine coating on front and rear elements beads water effectively for clear shots in wet conditions.

The Panasonic 25mm f/1.7 stands as the best budget prime available for the G9 II. At roughly $250, this lens delivers image quality that rivals lenses costing twice as much. The 50mm equivalent focal length provides a natural perspective for everyday photography and works well for portraits.

I appreciate the f/1.7 maximum aperture for several reasons. Low-light performance improves dramatically compared to kit lenses, and you achieve meaningful subject separation for portraits. The 7-blade aperture produces decent circular bokeh when shooting wide open, though not as creamy as more expensive options.

Build quality exceeds expectations for the price. The metal mount adds durability, and the compact 125-gram body complements the G9 II nicely without adding noticeable weight. This combination feels like a proper camera system rather than entry-level gear.

Autofocus operates quietly and smoothly, making this lens suitable for video work. The stepping motor focuses without the whining noise that plagues some older designs. Focus breathing is minimal, another plus for video shooters using this as a run-and-gun lens.

Best For Beginners and Street Photography

If you are starting with the G9 II, this lens teaches you how focal length affects perspective without breaking the bank. Street photographers value the discreet size and quiet operation. The 50mm equivalent view mimics human vision closely, making composition intuitive.

Considerations Before Buying

The lack of image stabilization means you rely on the G9 II body IS or faster shutter speeds. At f/1.7, this rarely presents problems in good light, but darker environments may require raising ISO. Some users report this lens feels chunkier than expected from pictures, though I found it manageable.

4. Olympus M.Zuiko Digital ED 12-40mm f/2.8 Pro

The Olympus 12-40mm f/2.8 Pro represents the professional standard zoom choice for Micro Four Thirds. I have used this lens extensively and can confirm it delivers exceptional results on the G9 II. The constant f/2.8 aperture throughout the zoom range makes this a true professional tool.

Lens construction includes 14 elements in 9 groups with multiple specialized lenses. ED, aspherical, DSA, HR, and HD elements all contribute to the outstanding optical performance. This complexity translates to images with minimal aberrations and excellent contrast across the frame.

The manual focus clutch mechanism deserves special mention. Pull the focus ring back to engage manual focus instantly, push it forward for autofocus. This tactile design exceeds touch-by-wire alternatives in both speed and precision. I prefer this system for video work where manual focus pulling adds cinematic effect.

Weather sealing matches professional expectations. The lens function properly in rain, dust, and temperatures down to 14 degrees Fahrenheit. This durability matters for photographers who work in challenging environments regardless of conditions.

Best For Professional Event Coverage

Wedding photographers, photojournalists, and event coverage professionals benefit most from this lens. The constant aperture means consistent exposure settings as you zoom, critical when lighting changes throughout an event. The professional build survives daily heavy use.

Considerations Before Buying

No optical image stabilization means the lens relies entirely on in-body stabilization from the G9 II. This is not a problem since the G9 II IBIS performs well, but users switching from stabilized lenses may notice the difference. The weight and bulk exceed typical zoom lenses, so factor portability into your decision.

5. Panasonic Leica DG SUMMILUX 9mm f/1.7 ASPH

The Panasonic Leica DG SUMMILUX 9mm f/1.7 fills a unique niche for wide-angle photography on the G9 II. I tested this lens for astrophotography and landscape work, finding it delivers outstanding results when you need broad views with fast aperture capability.

At 9mm (18mm full-frame equivalent), this prime captures sweeping landscapes and architecture effectively. The f/1.7 aperture enables handheld night photography where slower wide-angle lenses would require tripods. Stars and cityscapes become accessible without heavy equipment.

Leica quality means something here. Images exhibit the characteristic Leica contrast and color rendering that professionals recognize. The 0.25x magnification ratio approaches macro territory for a wide-angle lens, letting you capture foreground interest close to the camera while maintaining expansive backgrounds.

The fluorine coating simplifies maintenance. Fingerprints, water spots, and dust clean easily from the front element. This practical feature matters when shooting in field conditions where lens changes occur frequently.

Best For Astrophotography and Architecture

Night sky photographers benefit most from this lens. The fast aperture gathers enough light for Milky Way shots at reasonable ISO levels, and the ultra-wide field of view includes more sky in each frame. Architecture photographers appreciate the rectilinear design that keeps lines straight.

Considerations Before Buying

Manual focus only requires adjustment if you are accustomed to autofocus wide-angles. The G9 II focus peaking makes manual focusing practical, and the lens rings feel precise. Fast panning in video reveals slight edge distortion, though still photography remains excellent.

6. Sigma 30mm f/1.4 DC DN Contemporary

The Sigma 30mm f/1.4 stands out as exceptional value among primes for the G9 II. At around $400, this lens punches above its price tier, delivering sharpness and bokeh quality that rivals Panasonic Leica options costing significantly more. The 60mm equivalent focal length suits portraits and everyday shooting.

I measured sharpness across the frame at various apertures. At f/1.4, the center reaches near-maximum sharpness immediately, and edge performance improves through f/2.8. By f/4, the entire frame performs consistently. This tells me Sigma prioritized real-world performance over laboratory specifications.

Bokeh quality from 9 rounded aperture blades impresses me. Out-of-focus backgrounds render smoothly without nervous texture that plagues some lenses. Portrait photographers benefit significantly from this smooth background separation that makes subjects pop.

The 4-year warranty exceeds typical manufacturer coverage. Sigma confidence in this product translates to user peace of mind. Combined with the reasonable price point, this warranty makes the 30mm f/1.4 an easy recommendation for budget-conscious photographers refusing to compromise on quality.

Best For Portrait Photography on a Budget

If you want beautiful portrait separation without Leica pricing, this Sigma delivers. The f/1.4 aperture creates shallow depth of field quickly, and the 60mm equivalent flattering perspective suits face-on and three-quarter portraits. Low-light event photography also benefits from the wide aperture.

Considerations Before Buying

Chromatic aberration appears in high-contrast situations at f/1.4 but corrects easily in post-processing. Low-light focus hunting occasionally occurs, though the G9 II phase-detect AF minimizes this issue. The lack of an aperture ring disappoints video shooters who prefer tactile exposure control.

7. Sigma 16mm f/1.4 DC DN Contemporary

The Sigma 16mm f/1.4 DC DN fills the wide-angle fast prime void in the Micro Four Thirds lineup. I recommend this lens to G9 II users seeking astrophotography capability without spending Leica money. The 32mm equivalent focal length also works for street and environmental portrait work.

Lens construction includes 16 elements in 13 groups. This complexity includes FLD elements, SLD elements, and molded aspherical elements working together. The result is minimal aberrations and outstanding sharpness across the frame even at maximum aperture.

The Super Multi-Layer Coating handles backlit situations effectively. I photographed sunset scenes with the sun in frame and found flare and ghosting minimal compared to untreated lenses. This coating technology makes the 16mm f/1.4 practical for demanding lighting conditions.

Autofocus uses a stepping motor optimized for mirrorless cameras. The G9 II communicates smoothly with this motor, achieving focus quickly in most situations. Manual focus override remains available when you need it for precise control.

Best For Astrophotography and Low-Light Wide Shots

The 16mm focal length on G9 II creates an excellent night sky lens. Stars render as sharp points rather than trailing significantly at exposures under 20 seconds. The f/1.4 aperture gathers enough light for impressive Milky Way photography without extremely high ISO settings.

Considerations Before Buying

Weight and size exceed typical Micro Four Thirds expectations. At 405 grams, this Sigma approaches pro zoom territory. If you prioritize compactness, this lens may disappoint. The 67mm filter size also means additional expense for filters compared to smaller lenses.

8. Olympus M.Zuiko Digital 45mm f/1.8

The Olympus 45mm f/1.8 delivers portrait capability at an accessible price point. I found this lens excels at casual portrait work where larger lenses would feel excessive. The 90mm equivalent focal length provides flattering compression for face photography.

Weighing just 116 grams, this lens barely registers on the G9 II. You can carry it all day without fatigue, making it ideal for travel situations where you want portrait capability without dedicated bag space. This pocketable quality transforms how I think about carrying lenses.

Image quality benefits from the 7-blade rounded diaphragm. Bokeh circles remain smooth and circular rather than mechanical-looking. For portrait photography where background blur quality matters, this Olympus performs beyond its price category.

Silent autofocus operation suits video recording. The movie-still-compatible lens drive produces no motor noise during focusing, preserving clean audio tracks. If you shoot hybrid content with your G9 II, this lens deserves consideration.
