OM-1 Mark II

The OM SYSTEM OM-1 Mark II is purpose-built for bird photography, featuring intelligent AI Detection AF that locks onto birds in flight — even when they’re flying directly towards the camera. Its ultra-fast stacked sensor readout enables 50fps AF/AE bursts, 120fps fixed AF, and a blackout-free EVF, allowing you to track subjects smoothly without losing sight.

Pro Capture acts as a “pre-shutter,” buffering frames before release so you never miss sudden take-offs or landings. Unlike many rival cameras that drop to JPEG or lower resolution in high-speed modes, the OM-1 Mark II maintains full-resolution RAW with a generous 213-frame buffer.

Compact and weather-sealed, the system is easy to shoot handheld — around 2.5 kg with the M.Zuiko 150-400mm F4.5 TC1.25X IS PRO or 1.9 kg with the 100-400mm F5.0-6.3 IS II. Thanks to the Micro Four Thirds 2× crop, the 150-400mm delivers a 300–800mm F4.5 equivalent reach in a genuinely portable package. By contrast, full-frame systems offering similar reach (600mm or 800mm F4.0 primes) are typically at least twice as large, twice as heavy, and two to three times more expensive.

This combination of AI autofocus, stacked-sensor speed, uncompromised Pro Capture RAW, blackout-free tracking, extended telephoto reach, and unmatched portability makes the OM-1 Mark II one of the best bird photography cameras available today.

• AI Bird Detection AF tracks birds in flight, even flying head-on.
• 50fps AF/AE or 120fps fixed AF with blackout-free sequential shooting and up to 213 RAW buffer.
• Pro Capture pre-shutter eliminates human reaction delays to catch sudden take-offs and landings with ease.
• Handheld shooting possible with 150–400mm F4.5 TC1.25X IS PRO (~2.5 kg) or 100–400mm F5.0-6.3 IS II (~1.9 kg).
• Full-frame systems with similar reach are at least twice as large, twice the weight, and two to three times the cost.

The OM SYSTEM OM-1 Mark II is exceptional for macro photography, combining intelligent in-camera focus stacking with the inherent advantages of the Micro Four Thirds format: 2× greater depth of field and 2× effective magnification compared to full frame. Its best-in-class 5-axis image stabilisation ensures sharp results even at extreme magnifications where full frame often struggles.

The M.Zuiko macro lineup includes the 30mm F3.5 Macro, 60mm F2.8 Macro, and flagship 90mm F3.5 Macro IS PRO, alongside several telezooms with remarkably close focusing. These longer working-distance zooms make it easier to photograph delicate subjects such as butterflies without disturbing them, and can achieve true 1:1 macro reproduction with teleconverters. The 90mm F3.5 Macro IS PRO stands alone in the industry, delivering up to 4× equivalent magnification — or an extraordinary 8× with the MC-20 teleconverter — a capability unmatched by full-frame systems.

Fully weather-sealed and equipped with advanced computational tools like focus stacking and bracketing, the OM-1 Mark II makes handheld macro practical in rain, mist, or damp environments.

With stabilisation, computational precision, extended depth of field, long working distances, extreme magnification, and the most complete macro lens system available, the OM SYSTEM OM-1 Mark II confirms Micro Four Thirds as one of the best formats for macro photography.

• Micro Four Thirds delivers 2× depth of field and 2× effective magnification vs full-frame.
• Best-in-class 5-axis stabilisation and in-camera focus stacking for handheld sharpness.
• Dedicated M.Zuiko macro lenses: 30mm F3.5 Macro , 60mm F2.8 Macro, and 90mm F3.5 Macro IS PRO (up to 8× equivalent magnification with MC-20 teleconverter).
• M.Zuiko telezooms with close focus provide longer working distances for delicate subjects like butterflies.
• Full-frame systems lack such extreme magnification or a macro lens as advanced as the 90mm F3.5 Macro IS PRO.

The OM SYSTEM OM-1 Mark II excels in wildlife photography because reach, speed, and silence are essential in the field — and this system delivers all three. With the M.Zuiko 150-400mm F4.5 TC1.25X IS PRO, you already achieve a 300–800mm F4.5 equivalent thanks to the Micro Four Thirds 2× crop. Adding the MC-20 teleconverter, together with the lens’s built-in 1.25× converter, extends this to an extraordinary 2000mm equivalent, all in a system weighing around 2.5 kg and compact enough for handheld use. By contrast, full-frame setups offering similar focal lengths require 600mm or 800mm primes that are typically at least twice as large, twice as heavy, and two to three times more expensive.

The OM-1 Mark II’s silent electronic shutter allows you to photograph shy or sensitive animals without disturbance — essential for intimate behaviour and quiet environments. Intelligent AI Detection AF recognises and tracks wildlife, even when the subject is moving directly towards the camera. Meanwhile, the ultra-fast stacked sensor readout enables 50fps AF/AE bursts, 120fps fixed AF, and blackout-free EVF tracking to follow unpredictable movement seamlessly.

Pro Capture functions as a “pre-shutter,” buffering frames before you press the button so sudden leaps, chases, or take-offs are never missed. Unlike many rival systems that limit high-speed bursts to JPEG or reduced resolution, the OM-1 Mark II maintains full-resolution RAW with a generous 213-frame buffer.

With unmatched reach, silent operation, stacked-sensor speed, Pro Capture RAW, blackout-free viewing, and lightweight portability, the OM-1 Mark II is the ultimate companion for wildlife photographers.

• Silent shutter avoids disturbing sensitive animals.
• AI Subject Detection AF tracks mammals and birds, even head-on.
• Extreme reach: 300–800mm equivalent with 150–400mm F4.5 TC1.25X IS PRO, up to 2400mm with 150-600mm F5.0-6.3 IS and the MC-20 teleconverter.
• 50fps AF/AE or 120fps fixed AF with blackout-free shooting and 213 RAW buffer for unpredictable action.
• Full-frame wildlife kits offering similar reach are more than twice the size, weight, and price.

The OM SYSTEM OM-1 Mark II is ideal for landscape photography because it delivers professional image quality in a lightweight, highly portable system — allowing you to hike to remote viewpoints without heavy gear or tripods. With industry-leading weather sealing, it performs reliably in rain, snow, wind, or dusty conditions, so your creativity isn’t limited by the environment.

The camera offers advanced computational tools such as 14-bit High Res Shot (up to 80MP), Live ND, Live GND, and in-camera Focus Stacking. Live ND lets you smooth waterfalls, rivers, and moving clouds without carrying physical filters, while Live GND balances bright skies and darker foregrounds for perfect sunrise or sunset exposures. Focus Stacking extends depth of field even at lower f-values, preserving sharpness without diffraction softening. With 5-axis Sync IS and lenses like the M.Zuiko 12-100mm F4.0 IS PRO, you can capture multi-second handheld exposures that would normally require a tripod.

M.Zuiko’s telecentric lens design ensures corner-to-corner sharpness and outstanding optical detail. Wide-angle options include the 8-25mm F4.0 PRO (approx. 1 kg with body) and the 7-14mm F2.8 PRO (approx. 1.1 kg with body), while the 12-100mm F4.0 IS PRO (approx. 1.2 kg with body) offers an all-in-one solution for sweeping vistas and telephoto compression. For more creative perspectives, the 8mm F1.8 Fisheye PRO delivers a dramatic 180° field of view — the only lens of its kind in the market.

For nightscapes, the OM-1 Mark II provides Starry Sky AF for fast, accurate focusing on stars, and Live Composite for building star trails in real time without overexposure — making astrophotography intuitive and accessible.

By combining portability, computational precision, advanced nightscape tools, and a uniquely versatile lens system, the OM-1 Mark II allows landscape photographers to travel lighter, shoot longer, and capture exceptional detail without compromise.

• 14-bit High Res Shot up to 80MP and Focus Stacking deliver maximum detail and depth.
• Live ND for smoothing water and Live GND for balanced skies — no extra filters required.
• Wide options include 8–25mm F4 PRO, 7–14mm F2.8 PRO, and unique 8mm F1.8 Fisheye PRO (180°).
• The 12–100mm F4 IS PRO with Sync IS enables multi-second handheld long exposures.
• Full-frame landscape setups typically require heavier lenses and tripods, doubling the weight compared to OM SYSTEM solutions.

The OM SYSTEM OM-1 Mark II is built for action, featuring advanced Human Detection AF that locks precisely onto athletes to maintain sharp focus as they sprint, jump, or move directly towards the camera. Continuous AF sensitivity controls give photographers the ability to keep focus on the chosen athlete while ignoring players crossing in front or distracting background motion.

Powered by an ultra-fast stacked sensor, the OM-1 Mark II delivers 50fps bursts with full AF/AE tracking or up to 120fps in fixed AF, all with blackout-free EVF viewing. Pro Capture functions as a “pre-shutter,” buffering frames before the shutter is pressed so decisive moments — a sprinter leaving the blocks, a footballer’s strike, or a cyclist’s acceleration — are never missed. Unlike many rival systems that limit high-speed sequences to JPEG or reduced resolution, the OM-1 Mark II records full-resolution RAW with a 213-frame buffer.

Agility is a major advantage. The compact, weather-sealed body paired with lightweight M.Zuiko telephoto lenses makes the system easy to manoeuvre along sidelines or in crowded stadiums. Unlike full-frame setups that often require heavy 400mm or 600mm lenses mounted on monopods, the OM-1 Mark II can be used handheld, allowing photographers to move freely and react instantly as the action unfolds.

This combination of Human Detection AF, customisable continuous AF, stacked-sensor speed, Pro Capture RAW, and unmatched portability makes the OM-1 Mark II a powerful and flexible tool for sports and action photography.

• Human Detection AF locks onto athletes with precision.
• Continuous AF sensitivity control keeps tracking on the intended subject.
• 50fps AF/AE or 120fps fixed AF with blackout-free shooting and 213-frame RAW buffer.
• Pro Capture pre-shutter overcomes reaction delays to freeze critical moments.
• Full-frame action systems need heavier 400mm/600mm primes tied to monopods, reducing agility.

The OM SYSTEM OM-1 Mark II features the most advanced sensor technology ever seen in a Micro Four Thirds camera — a stacked BSI (Back-Side Illuminated) Live MOS sensor. This state-of-the-art design dramatically increases readout speed by placing circuitry behind the light-gathering surface, allowing more light to reach each pixel and reducing electronic noise.

The ultra-fast stacked architecture provides significant advantages:

• Reduced rolling shutter for distortion-free capture of fast-moving subjects.
• Blackout-free sequential shooting for uninterrupted EVF tracking.
• Exceptional burst performance — up to 50fps with AF/AE tracking or 120fps in fixed AF, recorded in full-resolution RAW.
• Improved low-light capability, with up to a +2 EV performance gain compared to conventional CMOS sensors, thanks to the BSI layout maximising light efficiency.

This technology, normally found in flagship full-frame sports cameras costing several times more, brings professional-level speed and image quality to a compact, lightweight system at an accessible price point.

In real-world use, the stacked BSI sensor is transformative: whether tracking birds in flight, capturing unpredictable wildlife, or freezing the decisive moment in sports, it ensures you respond instantly and never miss the shot.

The OM SYSTEM OM-1 Mark II and M.Zuiko lenses form a uniquely complete and highly capable system, combining ultra-fast stacked sensor speed, advanced computational photography, industry-leading 5-axis image stabilisation, and exceptional portability. The system achieves up to IP53 weather sealing — and OM SYSTEM is one of the few brands that officially certifies its weather resistance, giving photographers genuine confidence in demanding outdoor conditions.

Unlike many competitors, there is no inconsistency in lens–body compatibility. Every M.Zuiko lens is designed to work seamlessly with the OM-1 Mark II, ensuring reliable autofocus, stabilisation performance, and optical quality across the entire range. From ultra-wide to super-telephoto, and from specialist macro to versatile all-in-ones, the M.Zuiko PRO lineup is one of the most complete mirrorless lens ecosystems available.

Thanks to the Micro Four Thirds format, photographers benefit from extended telephoto reach in significantly smaller and lighter lenses. For example, the M.Zuiko 150-400mm F4.5 TC1.25x IS PRO delivers a 300–800mm equivalent field of view in a system weighing around 2.5 kg — whereas full-frame equivalents are typically more than twice the size, twice the weight, and two to three times the price. Full-frame systems also lack such a comprehensive choice of focal lengths, accessories, and specialised optics.

Add in computational tools such as Live ND, Live GND, Focus Stacking, and High Res Shot — plus Pro Capture RAW bursts up to 120fps — and the OM-1 Mark II offers capabilities that competing systems cannot match at any price point.

Ultimately, it raises the question: what other system delivers this combination of speed, computational power, stacked sensor technology, guaranteed lens compatibility, extended reach, trusted weather sealing, and genuine portability — all at such an accessible price?
