Olympus E-M1 Mark III vs Panasonic Lumix FZ1000 II: A Thorough Camera Comparison

When diving into the camera market’s crowded waters, choosing between Olympus’s OM-D E-M1 Mark III and Panasonic’s Lumix FZ1000 II can feel daunting - especially since they target somewhat overlapping but ultimately distinct user needs. Having personally tested thousands of cameras over 15 years, including hundreds in the mirrorless and bridge camera realms, I leverage those experiences to dissect these two contenders in minute detail. In this comprehensive comparison, I’ll walk you through sensor technologies, handling, autofocus systems, image quality, and much more - so you can confidently decide which model aligns best with your photographic style and goals.

First Impressions: Size, Handling and Design

The Olympus E-M1 III favors a more traditional DSLR-style mirrorless body, featuring a robust, professional feel. In contrast, the Panasonic FZ1000 II is a superzoom bridge camera with a bulkier, SLR-like shape but with a fixed lens.

I always start by noting physical handling in real-world shooting scenarios. Olympus keeps its weight light at 580g, which is impressive given the weather sealing and robust build quality. It measures a compact 134x91x69 mm, making it easy to grip comfortably for extended shoots. Panasonic’s FZ1000 II, by contrast, weighs 808g and feels noticeably larger at 136x97x132 mm due to its fixed 25-400mm zoom lens, adding bulk especially when hand-holding for long periods.

If portability and prolonged handheld use in travel or street settings matter, Olympus’s smaller, lighter body scores points. However, Panasonic’s bridge design does deliver versatility with an all-in-one superzoom lens, which can be a game changer for users reluctant to swap lenses.

Control Layout and Usability

Both cameras feature fully articulated 3-inch touchscreens and high-resolution electronic viewfinders (EVFs) with 2.36 million dots. Olympus integrates a high magnification EVF (0.74x) providing a bright, immersive framing experience, matched by Panasonic’s similar spec EVF.

Olympus fully embraces manual controls with a dedicated front and rear dial, customizable buttons, and a dedicated AF joystick - details I found invaluable during fast-action shoots. The mode dial is easily accessible, and menu navigation is logically laid out for photographers who appreciate tactile feedback and fine control. Panasonic, with its bridge camera layout, offers decent button placement but lacks an AF joystick, which can slow focus point adjustments under pressure. It targets users who prefer more automated shooting aids.

Sensor Performance Deep Dive: Micro Four Thirds vs 1-inch

Sensor size and technology form the foundation of image quality differences here. Olympus employs a 20.4-megapixel Micro Four Thirds (MFT) Live MOS sensor measuring 17.4 x 13 mm, while Panasonic packs a 20.1MP 1-inch BSI-CMOS sensor at 13.2 x 8.8 mm.

In terms of surface area, Olympus's sensor is almost double the size (226.2 mm²) of Panasonic’s smaller 116.16 mm² sensor. This difference generally favors better noise control, dynamic range, and highlight retention on the Olympus - especially relevant in low light, landscapes, and skin tones in portraits.

Thanks to the TruePic IX processor, Olympus extracts excellent detail and ultra-low noise levels up to ISO 6400 or 12800 when necessary, with more natural color gradations and refined textures. Panasonic’s 1-inch sensor with its Venus Engine processor holds its own well at base and mid ISOs with punchy colors and decent sharpness but struggles slightly more in low light due to smaller pixel pitch.

The antialiasing filter absence on the Olympus sensor helps maximize sharpness and micro-contrast, which benefits landscape and macro shooters craving every bit of detail. Panasonic retains an AA filter, smoothing moiré but slightly softening fine textures.

Autofocus Systems: Precision and Speed Under Pressure

Olympus offers a hybrid AF system with 121 contrast and phase detection focus points. The system features face detection with eye autofocus, continuous AF, and 60 frames per second burst rate with AF tracking - the latter a standout for wildlife and sports photographers.

Panasonic operates contrast-detection-only AF with 49 selectable points - somewhat fewer and generally slower to lock in on fast subjects. Burst speed is capped at a max of 12 fps, sufficient for casual action but limiting for tracking rapid wildlife or athletes.

Eye detection is strongly implemented on Olympus and shines in portrait sessions by locking sharply on the eyes even with moving subjects. This is something I found Panasonic’s system less reliable with, occasionally hunting in dimmer environments.

Build and Durability: Weather Sealing vs Solid Bridge Design

Olympus’s weather sealing is a major professional plus, rated dust- and splash-proof and freeze-proof down to -10°C. This makes it ideal for outdoor landscape, wildlife, and adventure photographers who require reliability in difficult conditions. For instance, I tested the E-M1 III during a damp forest shoot and appreciated its resilience.

Panasonic FZ1000 II, while robust, lacks weather sealing. Its body is built well but intended more for casual to enthusiast shooters not expecting harsh environmental endurance.

Image Quality in Use: Field Tests Across Genres

Portrait Photography

The superior dynamic range and color depth of Olympus’s MFT sensor enable impressively natural skin tones and fine detail retention - even at wide apertures with Micro Four Thirds lenses from Olympus or Panasonic. Its 121-point AF with eye detection helps isolate subjects sharply, with smooth background bokeh courtesy of high-quality native lenses.

Panasonic’s smaller sensor coupled with its fixed zoom lens fares well in general portraits but can’t match the creamy bokeh or fine detail of Olympus. The FZ1000 II’s slower autofocus and fewer focus points makes portraiture less fluid especially with moving subjects.

Landscape Photography

With 20 MP native resolution, Olympus offers files up to 5184×3888 pixels that reveal subtle tonal transitions and excellent highlight preservation thanks to its better dynamic range. The absence of an AA filter boosts crispness in foliage and architectural detail - a must for landscape photographers. Combined with in-body 5-axis image stabilization, handheld long exposures become more practical.

Panasonic FZ1000 II provides a versatile zoom spanning wide 25mm to 400mm equivalent, enabling sweeping landscapes to compressed telephoto shots without lens changes. However, its smaller sensor reduces dynamic range and shadow detail, and noise control is less effective at higher ISO settings common during golden hour shooting.

Wildlife and Sports Photography

Autofocus speed and burst rate dominate these genres. Olympus’s blazing 60 fps burst with continuous AF tracking is remarkable in my hands for capturing fast-moving birds or athletes, enabling high keeper rates. Its lens market includes numerous fast telephoto lenses ideal for distant subjects.

Panasonic’s 12 fps burst and contrast-only AF make tracking dynamic subjects more challenging. However, the built-in 25-400mm lens still covers most wildlife shooting needs with decent reach, making it suitable for casual enthusiasts unwilling to invest in multiple lenses.

Street and Travel Photography

Olympus’s compactness, weather sealing, and discreet shutter system make it the better tool for street photographers who demand inconspicuous setups. The MFT lens ecosystem offers small primes and zooms that maintain portability.

Panasonic, although bulkier and heavier, boasts an all-in-one lens minimizing gear changes during travel. Its articulating touchscreen works well for candid angles and low-level shots. However, the larger size might draw more attention on the street.

Macro Photography

Olympus wins again thanks to a more comprehensive lens ecosystem including dedicated macro lenses and superior focusing technology with focus bracketing and stacking - ideal for capturing extreme close-ups with precise detail. The FZ1000 II’s close focusing distance of 3cm is respectable but limited by fixed aperture and lens design.

Night and Astro Photography

Thanks to its larger sensor, superior noise handling, and ISOs reaching 25600 native, Olympus is more adept in astro and night scenarios, especially when paired with manual exposure modes and silent shutter options. Its in-body stabilization aids longer handheld exposures.

Panasonic serves well for casual night shooting, but noise becomes more apparent above ISO 3200, and the maximum electronic shutter speed of 1/16000s limits creative shutter control at night.

Video Capabilities: 4K Performance and Beyond

Both cameras support 4K video, but Olympus leads with UHD recording at 4096 x 2160 (C4K) 24p and 3840 x 2160 30p, encoded with MOV and H.264 at high bitrates (up to 237 Mbps). Olympus also provides headphone and microphone input for professional audio control.

Panasonic shoots 4K UHD 30p and Full HD up to 60p with similar codecs but tops out at 102 Mbps bitrate. Notably, Panasonic lacks a headphone jack limiting on-set audio monitoring.

Both cameras feature fully articulating touchscreens useful for vlogging or creative angles. Panasonic includes 4K photo mode (high-res frame grabs from video) which Olympus does not. Olympus’s superior stabilization in video mode provides smoother handheld footage.

Practicalities: Battery Life, Storage, and Connectivity

Olympus offers dual UHS-II SD card slots, a boon for professionals backing up files instantly. Battery life rated at approximately 420 shots per charge aligns with mirrorless standards and ample for most shooting days.

Panasonic’s single SD slot supports UHS-I, which is slower and less versatile. Its lower battery life (350 shots) means carrying spares will be more critical on longer outings.

Both models include built-in Wi-Fi and Bluetooth for wireless transfer and remote control, though Olympus’s USB 3.1 port delivers speedier tethered shooting compared to Panasonic’s USB 2.0.

Price and Value Overview

At launch, Olympus E-M1 Mark III carried a price near $1800 USD body-only. Panasonic FZ1000 II retails around $900 USD with lens included.

Olympus demands a premium reflecting its pro-grade build, advanced autofocus, and expansive lens ecosystem, targeted at serious enthusiasts and professionals. Panasonic appeals as an all-in-one superzoom for hobbyists or travel photographers seeking versatility on a budget.
