Choosing the right camera often means balancing features, performance, and convenience tailored to your shooting style and specific needs. With Sony’s Cyber-shot lineup spanning from the small-sensor superzoom bridge camera H400 to the ultracompact TX20, photographers face a stark contrast in design and capabilities. From sensor technology to autofocus prowess, and from ergonomics to image quality, we take a detailed look at these two cameras side-by-side, drawing on extensive hands-on testing experience.

First Impressions: Design, Build, and Handling in Real-World Use

Physical handling fundamentally shapes the shooting experience, particularly when switching between bridge-style superzooms and pocketable ultracompacts.

Form Factor and Ergonomics

The Sony H400 virtually mimics an SLR form factor with its robust bridge design. It features a sizable grip and ample physical controls, though it falls short of professional-grade weather sealing. In comparison, the TX20 is an ultracompact, pocketable device meant for maximum portability, boasting a lean, slim body.

Handling the H400 is a far more deliberate, “serious photography” experience; the hefty 628-gram weight combined with a deep grip encourages stability, which is beneficial especially when using the extreme zoom range. The TX20, weighing a featherlight 133 grams, fits effortlessly in one hand and even small pockets, making it an ideal companion for casual shooting and travel scenarios where discretion and carry convenience are paramount.

Control Layout and Interface

Sony’s design philosophy is apparent when comparing the top decks of both cameras. The H400 presents a traditional control layout with multiple dials and buttons allowing manual override over exposure parameters such as shutter speed and aperture - features lacking in the TX20.

The TX20’s minimalist approach sacrifices dedicated manual controls for touchscreen navigation, improving usability for point-and-shoot styles but limiting creative control. Despite the TX20’s advanced touchscreen incorporating Sony’s XtraFine TruBlack technology for high contrast and visibility, the H400’s fixed 3-inch Clear Photo LCD is sufficiently clear, albeit with lower resolution, favoring conventional button-based operation.

Sensor and Image Quality: The Heart of Photography

The sensor technology and size shape the core imaging capabilities and ultimately impact detail rendition, noise performance, and dynamic range.

Sensor Specifications and Architecture

Both cameras employ the same 1/2.3-inch sensor size (6.17 x 4.55 mm) with similar active sensor areas (~28 mm²), a common dimension in consumer point-and-shoot and bridge cameras. However, the H400 utilizes a 20-megapixel CCD sensor, whereas the TX20 incorporates a 16-megapixel BSI-CMOS sensor, a significant architectural difference that translates to varying performance profiles.

Many photographers familiar with sensor evolution know that CCD sensors, while offering excellent color fidelity and less rolling shutter distortion, tend to struggle with high ISO noise and dynamic range against BSI-CMOS counterparts. The TX20's back-illuminated CMOS design enhances its low-light sensitivity and dynamic range, compensating partly for its lower resolution.

Effective Resolution and Image Quality Outcomes

Under controlled lab and real-world testing conditions, images from the H400 are slightly sharper in good lighting due to its higher pixel count, but the TX20 consistently delivers cleaner images at higher ISO values (ISO 800 and above), vital for scenarios like indoor events or dusk shooting.

Chromatic aberrations and color accuracy between the two are roughly comparable, though the CCD’s inherent characteristics in the H400 can lead to slightly warmer skin tones, appreciated in portraiture but less versatile overall.

Autofocus and Performance: Speed, Accuracy, and Reliability

Autofocus (AF) is paramount across all genres, from wildlife action bursts to macro detail work.

AF Technologies Compared

Both models use contrast-detection autofocus systems with face detection capabilities, but neither employs phase-detection AF or hybrid systems common in modern mirrorless cameras. The H400’s AF system lacks continuous AF and live view AF, relying solely on single AF mode, whereas the TX20 supports continuous AF with touch focus - a notable advantage for moving subjects.

None of these cameras support animal eye AF, now an essential feature for wildlife specialists, nor do they feature advanced AF tracking algorithms.

Real-World Autofocus Behavior

In practical use, the H400’s autofocus is relatively slow and less responsive to fast-moving subjects, limiting its utility in sports or wildlife photography despite the massive 63.3x optical zoom. Its single shot focus and limited tracking capabilities make precisely timed action shots challenging.

Conversely, the TX20 benefits from quicker AF acquisition and touch-af functionality but is restricted by a narrower 4x zoom range, reducing its reach for subjects at distance.
