When you’re choosing a Micro Four Thirds mirrorless camera, the market spans a vast spectrum - from entry-level gems designed with beginners in mind, all the way to pro-grade powerhouses loaded with cutting-edge tech. Today, I’m diving into two standout cameras that epitomize these ends of the spectrum: the Olympus OM-D E-M10 IV and the Panasonic Lumix GH6. Having put thousands of cameras through rigorous testing, I’ll break down how these two stack up across shooting styles, specs, real-world usability, and value.

This is more than a specs sheet; it’s a practical guide to help you find the right tool for your photography quest.

First Impressions: Size, Build, and Handling

Right off the bat, the physical differences between these two cameras tell a story about their intended audiences.

The Olympus E-M10 IV is a lightweight, compact 383g body - ideal for beginners or travelers who want a pocket-friendly setup without sacrificing image quality. Its relatively small footprint (122x84x49mm) makes it easy to hold steady for hours, and the classic SLR-style design champions simplicity without intimidating controls.

The Panasonic GH6 tips the scales at a robust 823g, almost twice as heavy, with a much chunkier body (139x100x100mm). This weight comes with the territory of a professional rig built for heavy-duty use and extended shooting sessions. The magnesium alloy frame provides sturdy weather sealing, giving it a real edge outdoors.

Jumping from one to the other feels like trading a nimble sprinter for a rugged marathoner - both capable, but optimized for different distances.

Control-wise, the GH6 pulls ahead with more dedicated dials, customizable buttons, and a top LCD for quick exposure checks. The E-M10 IV offers a more straightforward layout with fewer physical controls - friendly for novices, but it might feel limiting as your craft evolves.

Both cameras feature tilting LCDs; however, the GH6 boasts a fully articulated screen that flips out and around, invaluable for vloggers and macro shooters who need awkward angles.

Sensor and Image Quality: The Heart of the Matter

The fundamental difference in sensor technology and resolution between these two is telling:

• Olympus E-M10 IV: 20MP Four Thirds sensor with an anti-alias filter for smoother images.
• Panasonic GH6: 25MP Four Thirds sensor, unique in forgoing an anti-aliasing filter, which allows for sharper detail but requires high-quality lenses to avoid moiré.

In practical use, the GH6 provides an edge in resolution and resolving power, beneficial for landscape or commercial photographers who crop extensively or print large. The E-M10 IV’s sensor is no slouch, producing pleasing images with excellent color rendition - perfect for portraits and everyday shooting.

Low-light capability is a close race given both max out at ISO 25600, but the GH6’s cleaner noise profile (backed by newer processing) grants it a boost in dawn or dimly lit venues, making it superior for event or night shooters.

Autofocus: Precision When It Counts

Olympus's E-M10 IV relies entirely on contrast-detection autofocus (CDAF), featuring 121 focus points that cover a fair portion of the frame. It supports face detection, and while impressive for its class, it lacks phase-detection autofocus (PDAF), which Panasonic also skips on the GH6 but compensates with a hybrid approach and enhanced tracking algorithms.

The GH6 adds animal eye AF, a newer feature that Olympus does not have in this model, enhancing critical focus speed and accuracy for wildlife and pet photography - invaluable when shooting unpredictable subjects.

In fast-action conditions like sports or wildlife, the GH6’s superior computational abilities and 14 fps continuous shooting give it a decisive advantage over the E-M10 IV’s 8.7 fps.

Performance in the Real World: Photography Styles Explored

Let’s break down how each camera performs across popular photography genres:

Portrait Photography: Nailing Skin Tones and Expression

The Olympus E-M10 IV’s 20MP sensor paired with Olympus’s color science delivers warm, natural skin tones in JPEGs straight out of the camera. The in-body 5-axis stabilization helps portrait shooters handhold longer lenses without blur. However, its contrast-detect AF can struggle slightly with eye tracking in low-light or busy backgrounds.

The GH6’s 25MP sensor ensures crisp detail and more resolution for cropping. Its animal eye AF can detect and lock precisely on eyes, even in challenging lighting. This makes it a better choice for studio or environmental portrait photographers needing pinpoint focus. Additionally, the full articulation of the screen helps when framing tight poses or tricky angles.

Landscape Photography: Dynamic Range and Detail

Landscapes demand high resolution and dynamic range to capture subtle nuances in skies and shadows. While neither uses a full-frame sensor, the GH6’s anti-alias filter-free 25MP sensor gives it an edge in resolving fine detail without unwanted softness.

Weather sealing on the GH6 is a critical advantage, allowing it to shoot confidently in damp, dusty, or cold environments - conditions that might give the E-M10 IV pause. The Olympus, meanwhile, impresses with its ease of use and compactness, a great companion on hikes where every ounce counts.

Focus bracketing on both cameras supports extended depth-of-field shots necessary for macro and landscape photographers, though the GH6 extends this further with post-focus and focus stacking capabilities.

Wildlife Photography: Speed and Tracking

Capturing elusive wildlife demands swift autofocus and faster continuous shooting. Here the GH6 commands the stage with 14 fps and animal eye AF, meaning it tracks birds or mammals with superior reliability.

The Olympus E-M10 IV’s contrast-detect AF lags a step behind, making it less suited for rapid subjects or extended bursts. Its smaller buffer and slower shooting speed also limit prolonged action sequences.

Sports Photography: Tracking and Frame Rates

Sports shooters prize rapid frame rates and consistent autofocus tracking. The GH6’s 14fps burst rate, combined with its advanced AF system, handles rapid movements and chaotic scenes with aplomb.

The E-M10 IV's slower 8.7 fps and less sophisticated AF mean you might miss subtle moments. For casual sports or kids’ games, it suffices; for professional or semi-pro sports photography, it’s not the ideal tool.

Street Photography: Discretion and Portability

If blending into the scene is paramount, the Olympus’s small form factor and simpler controls make it a stealthy companion. Its flash built-in for quick fills is a plus in dim café or sidewalk scenarios.

The GH6 is noticeably larger and louder, potentially drawing unwelcome attention. This isn’t a camera you pull out casually on crowded streets without notice. However, its fully articulating screen and excellent low-light sensitivity can aid creative compositions when discretion is less critical.

Macro Photography: Precision and Stabilization

Both cameras employ 5-axis sensor stabilization that proves critical during handheld macro shoots where every tremor is magnified. The GH6 offers real-time focus stacking, an automated way to capture razor-sharp extended focus sequences - a major time-saver for enthusiasts and professionals.

The E-M10 IV supports focus bracketing but lacks post-focus stacking features, meaning more manual work and slower output.

Night & Astrophotography: Low Light Performance and Exposure Control

Night sky shooters will find the GH6 preferable, thanks to its cleaner high-ISO performance, fully articulating screen for awkward framing, and faster shutter speeds up to 1/32000s, allowing more flexibility with long exposures and light trails.

The Olympus’s max shutter at 1/16000s is respectable, and it offers silent shutter mode, but noise is more pronounced beyond ISO 3200 compared to the GH6.

Video Capabilities: From Casual Clips to Professional Cinematography

Video is where the Panasonic GH6 positions itself as a modern multimedia workhorse:

• Max resolution: 5.7K (5760 x 2880) at 60p - ideal for high-res content creators, broadcasters, and filmmakers.
• Codec support: MPEG-4, H.264, and H.265.
• Ports: Both microphone and headphone jacks for serious audio monitoring.
• 4K 120p capabilities enable smooth slow-motion.
