Best Lenses for Olympus OM SYSTEM OM-1 II

OM SYSTEM 12-40mm f/2.8 PRO II — The Ultimate Professional Workhorse

If you only own one lens for your OM-1 II, this should be it. By refining an already legendary optical formula with superior IP53 weather sealing and advanced fluorine coatings, OM SYSTEM has created a standard zoom that matches the rugged, go-anywhere ethos of their flagship body. It delivers prime-like sharpness across the entire 24-80mm (equivalent) range, serving as a versatile tool for everything from wide-angle landscapes to tight environmental portraits.

Key Specifications

• Focal Length: 12-40mm (24-80mm full-frame equivalent)
• Aperture: Constant f/2.8 maximum
• Weather Resistance: IP53 Rated (Dust, Splash, and Freezeproof)
• Minimum Focus: 20cm across the entire zoom range
• Weight: 382g (13.5 oz)
• Special Features: Manual Focus Clutch and Fluorine Coating

The "Mark II" designation brings meaningful upgrades to the physical durability of the lens. While the 14-element optical construction remains consistent with its predecessor, the improved ZERO coating significantly reduces ghosting and flare. Its 0.6x equivalent magnification is a standout feature; while the M.Zuiko 60mm f/2.8 Macro (#2 on our list) is superior for dedicated insect photography, this zoom’s 20cm close-focusing ability allows you to capture stunning "near-macro" shots of flowers or food without swapping glass. The inclusion of the Manual Focus Clutch—a mechanism where you pull the focus ring back to engage a tactile distance scale—remains one of the most intuitive ways to handle manual overrides in the Micro Four Thirds ecosystem.

Users on r/M43 frequently describe this as their "permanent" lens, noting that its "tank-like" build quality provides confidence in torrential rain or dusty environments. While some photographers using smaller bodies like the Lumix GX9 find it slightly front-heavy, it balances perfectly on the substantial grip of the OM-1 II.

• Best for: Professional travel photographers, hikers who need total weather protection, and those who want one lens to handle 90% of their shooting needs.
• Skip if: You already own the original Olympus 12-40mm PRO and don't require the enhanced IP53 rating, or if you prefer the ultra-lightweight profile of the 14-42mm IIR (#10).

OM SYSTEM 60mm f/2.8 Macro — The Gold Standard for Tiny Subjects

The 120mm equivalent focal length provides a generous working distance that is essential for skittish insects, while the internal focusing mechanism ensures the lens barrel never extends toward your subject. It is a specialized tool that manages to be both clinically sharp for macro work and surprisingly flattering for portraiture.

Key Specifications

• Focal Length: 60mm (120mm full-frame equivalent)
• Maximum Aperture: f/2.8
• Magnification: 1:1 Life Size (2.0x 35mm equivalent)
• Weather Sealing: Dust, Splash, and Freezeproof
• Weight: 185g (6.5 oz)
• Minimum Focus Distance: 0.19m (7.5 inches)

While the 12-40mm f/2.8 PRO II (#1) is the better generalist, this 60mm prime is the undisputed king of detail. The inclusion of a four-position focus limit switch is a masterstroke; it allows you to toggle between close-up, landscape, or full-range modes, significantly reducing autofocus hunting. At just 185g, it is a featherweight addition to your kit that doesn't compromise on durability, featuring the same robust weather sealing found in the OM-1 II body. The optical construction, featuring 13 elements including ED and HR glass, delivers edge-to-edge sharpness that rivals lenses twice its size. The "featherweight" design makes handheld macro photography effortless, allowing for hours of shooting without wrist fatigue. While the focus-by-wire system is incredibly precise for fine-tuning, some may find it lacks the mechanical "click" of the clutch system found on the 12-40mm PRO. Note that you will likely want to source a third-party hood, as the omission of one in the box is a rare oversight for such a high-performing optic.

• Best for: Insect and flower photographers who need 1:1 magnification and a lens that can survive a rainstorm.
• Skip if: You only dabble in close-ups and would prefer the versatility of a zoom like the 14-150mm II (#6).

OM SYSTEM 17mm f/1.8 II — The Ultimate Weather-Sealed Street Prime

The OM SYSTEM 17mm f/1.8 II is a masterclass in "set and forget" photography, offering a classic 34mm equivalent field of view that feels natural for everything from environmental portraits to urban exploration. While it retains the proven optical formula of its predecessor, the addition of IPX1-rated weather sealing transforms it into a rugged companion that perfectly matches the go-anywhere ethos of the OM-1 II body.

• Focal Length: 17mm (34mm full-frame equivalent)
• Aperture Range: f/1.8 – f/22
• Weather Resistance: IPX1 Splash and Dustproof
• Weight: 112g (approx. 4.0 oz)
• Construction: All-metal barrel with ZERO coating

At just 112g, this lens is significantly lighter than the 12-40mm f/2.8 PRO II, making it the superior choice when weight is your primary constraint. The f/1.8 aperture provides a distinct advantage in low-light scenarios over the slower 14-150mm II, though street photographers should note that the manual focus clutch from the original version has been removed to achieve its featherweight, weather-sealed build. While corner sharpness hasn't seen a leap forward, the center remains tack-sharp, and the inclusion of the LH-49B lens hood adds immediate utility out of the box. Field testing reveals that the lens is so unobtrusive that it often stays mounted for entire trips, effectively turning the OM-1 II into a high-end point-and-shoot. Experienced photographers consistently find the new black-only finish provides a more cohesive, professional aesthetic on modern OM SYSTEM bodies compared to older silver iterations.

• Best for: Street photographers and travelers who need a fast, weather-sealed prime that fits in a jacket pocket.
• Skip if: You rely heavily on a physical push-pull manual focus clutch for zone focusing or require edge-to-edge clinical perfection.

OM SYSTEM 75-300mm f/4.8-6.7 II — Massive Reach in a Pocketable Package

While the OM-1 II is often paired with heavy "Pro" glass, this super-telephoto lens offers a unique proposition: a 600mm equivalent reach that weighs less than a single bottle of water. It transforms the flagship body into a nimble wildlife setup that won't strain your neck during long treks through the woods.

Key Specifications

• Focal Length: 75-300mm (150-600mm full-frame equivalent)
• Weight: 423g (0.93 lbs)
• Aperture: f/4.8 - f/6.7
• Autofocus: MSC (Movie & Still Compatible) high-speed drive
• Filter Thread: 58mm

The optical performance is surprisingly sharp between 75mm and 200mm, though it requires stopping down slightly at the 300mm long end to maintain contrast. Unlike the 12-40mm f/2.8 PRO II, this lens lacks weather sealing and internal stabilization. However, the OM-1 II’s industry-leading IBIS compensates beautifully for the lack of OIS, allowing for steady handheld shots even at full extension. It serves as a significant reach upgrade over the 40-150mm R, providing double the magnification for distant subjects.

Members of the DPReview forums frequently highlight the "stealth factor" of this lens, noting that its small profile doesn't startle wildlife like larger white-barrel lenses do. Conversely, users on r/M43 caution that the f/6.7 aperture requires ample daylight; once the sun dips, you will rely heavily on the OM-1 II's high-ISO performance to keep shutter speeds fast enough for birds in flight.

• Best for: Hikers and birdwatchers who prioritize portability and need maximum reach for daytime outdoor photography.
• Skip if: You frequently shoot in deep forests, at dawn/dusk, or require a weather-sealed kit for harsh environments.

OM SYSTEM 25mm f/1.8 II — The Rugged Nifty-Fifty for Everyday Carry

The 2025 refresh of this classic prime finally brings the "nifty-fifty" into the modern era by matching the ruggedness of the OM-1 II body. While it retains the beloved optical formula of its predecessor, the transition to a metal housing and IPX1 weather sealing transforms it from a fair-weather hobbyist lens into a reliable tool for unpredictable environments.

Key Specifications

• Focal Length: 25mm (50mm full-frame equivalent)
• Aperture: f/1.8 to f/22
• Weather Resistance: IPX1 Splash, Dust, and Freeze-proof
• Weight: 156g (5.5 oz)
• Minimum Focus: 0.24m (9.45 inches)

While the **12-40mm f/2.8 PRO II** (#1) offers more versatility, this 25mm prime provides a wider f/1.8 aperture in a footprint that is significantly more "pocketable." The inclusion of two aspherical elements ensures that sharpness remains high even when shooting wide open, though you may notice slight color fringing in high-contrast backlit scenes. Its MSC autofocus motor is virtually silent, making it a stealthy companion for street photography or video work where microphone noise is a concern. The build quality is a notable step up; the new metal exterior feels dense and premium compared to the plastic-heavy original. The weather sealing is the real game-changer here, allowing you to keep shooting in a drizzle without anxiety. However, the lens cap design remains a minor frustration, as it can be fiddly to remove when the included LH-49B hood is mounted.

• Best for: Street photographers and travelers who need a fast, weather-sealed prime that won't weigh down their kit.
• Skip if: You already own the **17mm f/1.8 II** (#3) and prefer a wider field of view, or if you require the manual focus clutch found on the PRO series.

OM SYSTEM 14-150mm f/4.0-5.6 II — The Ultimate One-Lens Hiking Solution

Field testing reveals that this superzoom is the "Swiss Army Knife" of the OM SYSTEM lineup, trading the clinical edge-to-edge sharpness of the 12-40mm PRO II for unparalleled versatility. It is a specialized tool for the minimalist adventurer who refuses to swap glass in unpredictable environments.

Key Specifications

• Focal Range: 14-150mm (28-300mm full-frame equivalent)
• Optical Zoom: 10.7x magnification
• Weather Protection: IPX1-rated dust, splash, and freeze-proof
• Weight: 285g (approx. 10 oz)
• Coating: ZERO (Zuiko Extra-low Reflection Optical)

While the 75-300mm offers more reach, this 14-150mm II is the superior choice for all-day trekking because it covers everything from wide-angle landscapes to tight wildlife portraits without a lens change. The inclusion of ZERO coating significantly mitigates ghosting and flare compared to its predecessor, though the f/5.6 aperture at the long end means you will rely heavily on the OM-1 II’s internal stabilization in dim forest canopies. It lacks the "pro" brightness of a constant aperture, but its 285g footprint is a marvel of engineering for a 300mm equivalent reach. Experienced photographers consistently find this to be the definitive "inclement weather" lens, noting that the seals hold up perfectly against heavy mist and dust. Long-term owners report that while the zoom ring can feel slightly resistive, the peace of mind provided by the rugged build outweighs the minor softness found at the extreme 150mm telephoto corners. Best for:

• Backpackers and hikers prioritizing a lightweight, single-lens setup.
• Travelers shooting in dusty or rainy environments where lens swaps are risky.

Skip if:

• You primarily shoot indoors or in low-light conditions where f/5.6 is too restrictive.
• You require the absolute corner-to-corner sharpness provided by the 12-40mm PRO II.

OM SYSTEM 40-150mm f/4.0-5.6 R — The Ultimate Lightweight Travel Telephoto

Affectionately known in the community as the "plastic fantastic," this lens defies its featherweight construction by delivering surprisingly crisp optical performance. While it lacks the rugged build of the PRO series, its ability to provide a 300mm equivalent reach in a package smaller than a soda can makes it an essential addition to any OM-1 II kit where mobility is the priority.

• Focal Length: 40-150mm (80-300mm equivalent)
• Weight: 190g (6.7 oz)
• Aperture Range: f/4.0 – f/5.6
• Focus System: MSC (Movie & Still Compatible)
• Filter Thread: 58mm

The 40-150mm f/4.0-5.6 R is a masterclass in Micro Four Thirds portability. Weighing a mere 190g, it pairs effortlessly with the OM-1 II, though the camera's robust IBIS is doing the heavy lifting here since the lens lacks internal stabilization. Optically, it is remarkably sharp in the center, especially when stopped down to f/8. While the 14-150mm II (#6) offers more versatility and weather sealing, this dedicated telephoto is significantly lighter and more compact for hikers or travelers. The MSC motor ensures autofocus is nearly silent and swift enough for candid wildlife or street photography. However, the all-plastic mount and lack of weather sealing mean you’ll need to be more cautious than you would be with the 12-40mm PRO II (#1). It is a specialized tool for those who want maximum reach with minimum physical footprint.

Best for:

• Travelers and hikers who prioritize a lightweight pack.
• Daylight wildlife and outdoor sports photography.
• Photographers wanting a 300mm equivalent reach that fits in a jacket pocket.

Skip if:

• You frequently shoot in heavy rain or dusty environments.
• You require a fast aperture for indoor sports or low-light action.
• You prefer the tactile feel of metal construction and manual focus clutches.

OM SYSTEM 17mm f/1.8 II — The Weather-Sealed Street Photography Specialist

The OM SYSTEM 17mm f/1.8 II is a polarizing update to a legendary lens. While it finally grants the OM-1 II a compact, weather-sealed prime that matches the body's ruggedness, it sacrifices a beloved tactile feature to get there. It remains a specialized tool for those who prioritize a "pocketable" kit without fearing a sudden downpour.

Key Specifications

• Focal Length: 17mm (34mm full-frame equivalent)
• Aperture: f/1.8 to f/22
• Weather Sealing: IPX1-rated (Dust and Splash-proof)
• Weight: 112g (Ultra-lightweight)
• Optics: 9 elements in 6 groups with ZERO coating

At just 112g, this "short stack" prime is 8g lighter than its predecessor, making it the ideal companion for the OM-1 II when you want to shed the bulk of the 12-40mm f/2.8 PRO II. The addition of IPX1 weather sealing is the headline feature here; you can now shoot street photography in the rain with total confidence. However, the removal of the manual focus clutch is a significant blow for purists. Without that physical "push-pull" ring, zone focusing becomes a menu-based chore rather than a tactile instinct. While the autofocus is instantaneous and silent, the optical formula hasn't changed since 2012, meaning it lacks the clinical sharpness found in the PRO series glass.

The autofocus performance is truly impressive, locking onto subjects with a snap that feels faster than the original. It is a "featherweight" marvel that balances perfectly on smaller bodies but serves as a great "stealth" option for the OM-1 II. However, the lack of a mechanical focus override is a step backward for those who grew up using this focal length for traditional street work.

• Best for: Travelers and street photographers who need a weather-sealed, ultra-compact prime for candid daily shooting.
• Skip if: You rely heavily on the manual focus clutch for zone focusing or require the absolute edge-to-edge sharpness of a PRO-series lens.

Olympus M.Zuiko 75-300mm f/4.8-6.7 II — Extreme Reach in a Pocketable Form Factor

While the OM-1 II is a professional-grade body, this lens serves as a lightweight gateway into wildlife photography for those who prioritize mobility over raw glass speed. It offers a staggering 600mm equivalent field of view in a chassis that weighs less than a pound, though it requires ample light to truly shine.

• Focal Length: 75-300mm (150-600mm equivalent)
• Maximum Aperture: f/4.8 - 6.7
• Weight: 423g (0.93 lbs)
• Filter Thread: 58mm
• Autofocus: MSC (Movie & Still Compatible)

The engineering feat here is the size-to-reach ratio; you are getting a 600mm super-telephoto experience in a lens smaller than many standard zooms. On the OM-1 II, the autofocus remains snappy thanks to the MSC motor, but the f/6.7 aperture at the long end pushes the camera's ISO capabilities when clouds roll in. While it lacks the weather sealing found on the 12-40mm f/2.8 PRO II, its portability makes it a favorite for casual hikers. Optical performance is peak between 75mm and 200mm, though stopping down to f/8 at the 300mm mark helps mitigate the natural softening that occurs at the far end of the zoom range.

Experienced photographers consistently find that this lens performs best in high-contrast, bright environments where the slow aperture isn't a hindrance. Long-term owners often recommend adding an aftermarket hood to prevent flare, as the front element is quite susceptible to stray light. Field testing reveals that while it isn't a "pro" optic, the sharpness is surprisingly resilient if the user manages their shutter speeds carefully.

Best for:

• Daytime wildlife and bird photography during long treks.
• Travelers who need maximum reach without a dedicated gear bag.

Skip if:

• You frequently shoot in deep forests, at dawn, or in rainy conditions.
• You require edge-to-edge professional sharpness at the maximum 300mm focal length.

M.Zuiko 14-42mm f/3.5-5.6 II R — Ultra-Lightweight Starter Zoom

While the OM-1 II is a professional-grade powerhouse, this lens serves as a featherweight entry point for those prioritizing portability over ruggedness. It delivers surprisingly sharp center performance and silent autofocus, though it lacks the weather sealing and mechanical refinement found in the 12-40mm f/2.8 PRO II.

Key Specifications

• Focal Length: 14-42mm (28-84mm full-frame equivalent)
• Weight: 113g (approx. 4.0 oz)
• Autofocus: MSC (Movie & Still Compatible) high-speed motor
• Minimum Focus: 0.25m (9.8 inches)
• Filter Thread: 37mm

The "II R" designation brings a refreshed aesthetic that complements the OM-1 II’s modern lines, but the internal optics remain focused on casual versatility. Its 113g footprint is nearly invisible in a camera bag, making it a functional backup for the 14-150mm f/4.0-5.6 II when you want to strip your kit down to the essentials. However, the manual retractable design requires a physical twist to "unlock" the lens before shooting, which can be a frustrating barrier during spontaneous moments. Furthermore, the plastic mount and lack of weather protection feel mismatched against the OM-1 II’s robust magnesium alloy body.

Best for:

• Casual day trips where weight is the primary concern.
• Discreet street photography or family home movies.
• Close-up photography of flowers or food thanks to the 0.38x equivalent magnification.

Skip if:

• You frequently shoot in rain or dusty environments.
• You require edge-to-edge sharpness for professional landscapes.
• You prefer a lens that is instantly ready to shoot without manual extension.
