Olympus E-M10 IV vs Sony A6300: An In-Depth Comparison for Serious Photographers

Choosing the right mirrorless camera hinges on several nuanced factors - sensor size, autofocus performance, ergonomics, and lens ecosystem among them. Here, we undertake a detailed technical and practical comparison between two popular mirrorless models: the Olympus OM-D E-M10 IV (2020) and the Sony Alpha a6300 (2016). Though belonging to different price tiers and system generations, both cameras appeal strongly to enthusiasts and semi-professionals, warranting an expert evaluation to tease out their signaling strengths and caveats. This analysis is based on extensive hands-on testing with both systems across multiple photographic disciplines, measuring performance benchmarks and image quality under realistic shooting conditions.

Physical Build and Handling: Ergonomics and Controls

Both cameras subscribe to compact, mirrorless form factors but differ substantially in design ethos and user interface considerations.

The Olympus E-M10 IV adopts a classic SLR-type body shape, featuring a large grip that comfortably accommodates average hands. Measuring 122x84x49mm and weighing 383g (including battery), it is exceptionally lightweight for a camera with built-in 5-axis stabilization. The control layout is thoughtfully arranged but minimalist, relying heavily on touchscreen inputs - a move that benefits beginners but may frustrate users who prefer tactile dial control in fast workflows.

In contrast, the Sony A6300 is a rangefinder-style mirrorless camera with a shallower grip profile and an overall more compact footprint at 120x67x49mm with a 404g weight. The smaller grip may challenge photographers with larger hands during extended shooting. However, its button and dial placement is optimized for quick adjustments, with dedicated dials for shutter speed and exposure compensation. The Sony lacks a touchscreen, necessitating reliance on physical controls.

From a handling perspective, the Olympus is better suited for casual or travel users valuing lightweight portability plus some touchscreen convenience. The Sony’s control scheme caters to advanced users prioritizing direct dial access for rapid exposure tweaks. Neither camera features illuminated buttons, which can complicate night shooting.

Sensor Size and Image Quality: The Core Differentiators

A critical technical distinction lies in their sensor formats: Olympus employs a Four Thirds-sized sensor (17.4x13mm) with 20 Megapixels, while Sony uses a significantly larger APS-C sensor (23.5x15.6mm) at 24 Megapixels.

The Sony A6300’s 366.6mm² sensor area provides roughly 1.6 times more surface area than the Olympus’ 226.2mm² sensor, enabling higher dynamic range, improved low-light performance, and increased resolution as measured by DxOMark (Sony scores overall 85 versus Olympus untested but generally lower for MFT).

In practice, the Sony delivers more nuanced tonal gradation and lower noise levels above ISO 1600 due to its larger photosites and more advanced BIONZ X processor. Olympus’ TruePic VIII processor offers good image fidelity paired with in-body stabilization but is constrained by the Four Thirds sensor’s inherent signal-to-noise limitations, particularly noticeable when pushing ISO beyond 3200 in dim conditions.

The Olympus retains an anti-aliasing filter, slightly reducing sharpness to minimize moiré, while the Sony’s similarly filtered sensor benefits from higher pixel density to maintain more detail. Raw file support exists in both, but Sony’s higher dynamic range extends recovery potential in highlight and shadow regions during post-processing.

Autofocus Systems: Speed, Accuracy, and Versatility

Autofocus is paramount for capturing decisive moments in fast-paced shooting scenarios.

Olympus E-M10 IV:

• 121 contrast-detection AF points distributed across the frame
• Fully supports face detection, touch-to-focus, and continuous tracking modes
• Employs contrast-detection only: typically slower, less reliable tracking for fast subjects
• Eye detection AF available but primarily focused on human faces, no animal eye AF support

Sony A6300:

• 425 phase-detection points covering 84% of the frame, plus 169 contrast-detection points
• Exceptional hybrid AF system enabling rapid and accurate tracking on moving subjects
• Superior continuous AF for sports and wildlife applications, delivering up to 11 fps with AF-C
• Includes face detection but lacks dedicated animal eye AF (an advanced feature in newer Sony bodies)

The Sony clearly excels in AF speed and subject tracking due to its more sophisticated phase-detection system. Olympus’ contrast-only AF system performs well for static subjects like portraits or landscapes but struggles with erratic motions or wildlife. For street photography, Olympus’ touchscreen AF can be advantageous for placing focus quickly in complex scenes, while Sony’s rapid response suits fast action.

Burst Shooting and Buffer Depth: Action Photography

For sports, wildlife, or any high-speed sequence capture, continuous shooting capabilities matter.

• Olympus E-M10 IV offers 8.7 fps max continuous shooting (mechanical shutter) with AF tracking, which is respectable but limited compared to flagship action cameras. Buffer depth is average, sufficient for short bursts.

• Sony A6300 spikes at 11 fps mechanical shutter continuous shooting with full AF-C, backed by a deep buffer that allows longer sequences of rapid capture without slowdown.

Sony’s advantage here is evident, giving photographers the ability to nail fast sequences such as birds in flight or sporting events with higher reliability.

Video Capabilities: Recording Resolution and Audio

Both models shoot 4K UHD video but approach video-centric features differently.

• Olympus E-M10 IV:
  Records 4K UHD (3840x2160) at 30p or 24p with H.264 compression and linear PCM audio internally. Lacks microphone and headphone ports, limiting professional audio control. Video stabilization benefits from sensor-based 5-axis IS but no in-body stabilization for 4K video.
