While both cameras feature 3-inch LCD displays, the NEX-5T’s screen offers tilting capabilities (up 180°, down 50°) with touchscreen functionality, enhancing flexibility in composition. The ZS25’s screen is fixed with lower resolution and lacks touchscreen input.

Control layouts reflect their target users:

The ZS25 operates with straightforward physical buttons and a control dial typical of compact superzooms. However, it lacks manual focus control and advanced customizability, limiting immediate exposure control for sophisticated shooters.

The NEX-5T provides greater manual input versatility, including full manual exposure modes with intuitive dials and customizable buttons, suited for photographers demanding granular control.

Sensor Technology and Image Quality Metrics

The foundational difference lies in sensor size and imaging capabilities, which directly influence dynamic range, noise performance, and depth of field control.

While both cameras boast 16 MP resolution, the NEX-5T’s vastly larger APS-C sensor delivers pronounced image quality advantages including richer color depth (DxOmark measured color depth: 23.6 bits vs. ZS25 untested), wider dynamic range (measured 13.0 EV vs. untested for ZS25), and substantially improved low-light sensitivity (ISO handling up to 25600 native vs. 6400 max ISO on ZS25).

Pragmatically, this translates to:

• Superior tonal gradation and highlight recovery in the NEX-5T, vital for landscape and portraiture demanding subtle shading.
• Lower noise and cleaner shadows at high ISO for indoor, event, or night photography contexts.
• The ZS25 is limited by its small sensor to noisier images, narrower dynamic range, and reduced potential for shallow depth of field effects.

Lens Systems and Focal Range Considerations

The ZS25 offers a fixed 24–480 mm equivalent lens (20× zoom), an impressive telephoto reach suitable for casual wildlife, travel, and landscape, but limited by relatively slow apertures (f/3.3–6.4) that constrain low light performance and creative depth of field control.

By contrast, the NEX-5T’s interchangeable Sony E-mount system provides extensive lens choices - currently over 120 lenses including primes, zooms, macros, and fast aperture options. This adaptability supports demanding photographic requirements across genres:

• Fast aperture primes for portraits and low light.
• Macro lenses for close-up precision.
• Telephoto zooms for sports and wildlife.

While the NEX-5T body does not offer built-in image stabilization, many lenses provide optical stabilization. Conversely, the ZS25 incorporates optical image stabilization directly in the lens, compensating somewhat for its smaller sensor and slower optics.

Autofocus Systems and Focusing Performance

Focusing technology is critical for capturing decisive moments, especially in wildlife, sports, and street photography.

The NEX-5T benefits from a hybrid autofocus system combining fast and accurate phase detection AF points with contrast detection, resulting in superior tracking and acquisition speed. Its 99 AF points with 25 cross-type enable more precise subject tracking in dynamic environments.

In practical shooting tests, the NEX-5T demonstrated faster lock times and better predictive tracking during continuous shooting bursts, crucial for wildlife and sports. The ZS25’s contrast-detection AF, while competent in static or well-lit scenes, exhibited lag in lower contrast or action scenarios.

Face detection on the NEX-5T adds utility in portraits and event photography, improving eye focus accuracy despite absence of dedicated eye AF modes. The ZS25’s lack of these modern recognition features limits portrait-focused autofocus reliability.

Image Stabilization and Burst Shooting

The ZS25 includes optical image stabilization (O.I.S.), effective at mitigating handshake in telephoto zoom ranges and low light without tripod use.

The NEX-5T’s body lacks in-body stabilization (IBIS), relying on optical stabilization inside compatible lenses. For users with stabilized lenses, this approach offers similar benefits, though only when using such glass.

Regarding burst speed, both cameras offer a respectable 10 frames per second (fps) continuous shooting rate, sufficient for casual action. However, the buffer depth and autofocus precision during continuous shooting favor the NEX-5T for prolonged sequences and complex subject tracking.

Video Capabilities and Audio Considerations

Both cameras support 1080p full HD video recording at 60 fps, adequate for high-quality video capture by 2013 standards.
