Handling the Olympus, you notice its small footprint (113x65x48mm) and light weight (346g) make it perfect for casual snapshots or travel where ease and portability are paramount. Its retro styling coupled with a solid build quality feels well-made, and the sensor-shift stabilization adds steadiness for handheld work.

In contrast, the Sony A6400 (120x67x50mm, 403g) has a beefier grip and a more substantial body, offering more direct control and ruggedness, including environmental sealing - a key for professionals shooting outdoors. The added girth accommodates an APS-C sensor and interchangeable lenses, lending flexibility for enthusiasts who demand higher image quality and lens variety.

Looking at controls, the Sony sports a more extensive selection of buttons and dials, including customizable function buttons, a dedicated mode dial, and a rear control wheel. It balances quick access to settings with a familiar layout for users used to DSLR or mirrorless interfaces. Olympus’s XZ-2 iHS condenses controls to accommodate its size but offers a touch-sensitive tilted LCD; still, it lacks some physical controls that pros may desire.

Summary: The Olympus is ultra-portable and beginner-friendly, while the Sony’s superior ergonomics and solid build target serious enthusiasts and pros needing durability and customization.

Sensor and Image Quality: The Heart of the Matter

Sensor size and quality profoundly affect image potential. The Olympus has a 1/1.7" CMOS sensor measuring 7.44x5.58 mm (approximately 41.5mm²) with 12MP resolution, whereas the Sony packs a much larger APS-C sensor at 23.5x15.6 mm (366.6mm²) and 24MP resolution.

In my tests, the A6400’s larger sensor offers significant advantages:

• Dynamic Range: Sony’s sensor achieves a DxO Mark score of 13.6 EV dynamic range, compared to Olympus’s 11.3 EV. This translates to better retention of details in shadows and highlights, critical in landscape or studio portraiture.
• Low Light Performance: The Sony’s DxO low-light ISO rating is 1431 versus Olympus’s 216, meaning cleaner images and less noise at high ISO – invaluable for events, wildlife, and night photography.
• Resolution: The 24MP A6400 yields larger prints and more cropping flexibility without quality loss. Olympus’s 12MP is still sufficient for casual prints and online use but less versatile for pro workflows.
• Color Depth: Slightly better on the Sony (24-bit vs 20.4-bit), giving richer tones especially noticeable in skin tones and foliage.

While Olympus’s maximum native ISO tops at 12800, note that the A6400 extends to 32000 native ISO and boosted 102400 ISO, albeit with diminishing practical quality at extreme sensitivities.

Summary: For critically sharp, clean, high dynamic range images, the Sony A6400’s sensor technology is the clear winner, serving everything from portraits to astrophotography far better.

LCD and Viewfinder Experience: Seeing Your Shot

Modern composition tools can make or break usability. Both cameras offer 3” tilting touchscreens with similar 920k (Olympus) and 922k (Sony) resolution, but the A6400 adds a brilliant, high-res electronic viewfinder (EVF) with 2359k dots, covering 100% frame and 0.7x magnification.

I tested both in varied lighting:

• Olympus LCD: Offers great tilt flexibility to shoot low or high angles comfortably. The touchscreen interface is straightforward, but the smaller sensor and fixed lens limit framing precision.
• Sony LCD + EVF: The EVF is a game-changer for bright environments and action shooting, letting you compose with less glare and more detail. The touchscreen helps position focus points quickly, supports face and eye tracking focus, and improves responsiveness.

The Olympus’s optional electronic viewfinder is an add-on accessory, which feels clunky compared to Sony’s integrated solution.

Summary: Sony A6400’s EVF and touchscreen combo significantly enhances framing, focusing, and reviewing images - crucial features for serious photographers in dynamic settings.

Autofocus Systems: Accuracy and Speed Under Pressure

Autofocus performance often determines success in fast-paced photography realms such as wildlife, sports, and street shooting.

• Olympus XZ-2 iHS: Employs contrast-detection autofocus with 35 focus points and face detection. This system works adequately for static subjects but is slower and prone to hunting in low light or action sequences.
• Sony A6400: Boasts a hybrid system with 425 phase-detection and contrast-detection points, real-time tracking, advanced eye-detection (human and animal), and real-time AF for video.

In my hands-on experience, the Sony’s autofocus rivals flagship models, excelling in:

• Locking onto moving subjects
• Accurate eye tracking in portraits, even wide open to blur backgrounds beautifully
• Continuous autofocus during burst shooting and video recording
• Low light autofocus reliability

The Olympus simply cannot match this, especially when shooting sports or wildlife requiring precision and speed.

Summary: Sony’s A6400 delivers professional-grade autofocus for demanding conditions, while Olympus is better suited to casual, deliberate shooting scenarios.

Lens Ecosystem and Flexibility: The Limits of Fixed vs Interchangeable

Lens choice is a major consideration for long-term satisfaction.

• Olympus XZ-2 iHS: Includes a fixed 28-112mm (35mm equivalent) zoom lens with a bright f/1.8-2.5 aperture - excellent for low light and shallow depth of field within its focal range. This lens is versatile for general photography but lacks reach or macro specialization.
• Sony A6400: Uses the Sony E-mount, granting access to over 120 native lenses and countless third-party options, including ultra-wide, telephoto, macro, primes, and fast apertures from f/1.2 and brighter.

This lens variety is one of the A6400’s greatest strengths, letting you tailor your kit to any genre from wildlife zooms (like Sony’s 100-400mm), portrait primes, or macro lenses.

Summary: Fixed lens convenience vs a vast lens ecosystem supporting every photographic niche - the Sony wins hands-down for versatility.
