This comparison dissects every relevant aspect - sensor technology, ergonomics, autofocus, shooting disciplines, and video capabilities - to empower you, the photography enthusiast or professional, in making an informed decision.

First Impressions and Physical Handling: Size and Ergonomics Matter

The most immediately noticeable difference between the RX1R and TX20 is size and build. The RX1R is a decidedly large sensor compact camera with a fixed 35mm f/2 lens, intended to deliver DSLR-quality imagery in a relatively pocketable form. In contrast, the TX20 is an ultracompact point-and-shoot camera, designed primarily for portability and straightforward operation.

The RX1R measures a substantial 113 × 65 × 70 mm and weighs approximately 482 grams, giving it solid heft and excellent grip for handheld shooting, with physical controls easily manipulated even in challenging conditions. Its metal body offers a confident, high-quality feel suited for serious photography. The TX20, at 96 × 56 × 18 mm and only 133 grams, is drastically smaller and lighter, slipping effortlessly into pockets or purses, but with a correspondingly smaller grip area and fewer dedicated buttons.

In comparison, the RX1R’s design prioritizes tactile control and professional handling, while the TX20 maximizes portability and simplicity. This reflects their intended audiences - the RX1R for photographers who demand manual input and fine control, the TX20 for casual users who want easy-to-use point-and-shoot functionality.

The control layouts reinforce these use cases: The RX1R features an abundance of physical dials and buttons, including aperture and shutter speed rings on the lens and top-deck dials, providing fast access without menu diving. The TX20 relies on a touchscreen interface with a minimal button complement, which appeals to users accustomed to smartphones but may limit quick adjustments under dynamic conditions.

Ergonomically, the RX1R is ideal for photographers who value direct manual control and extended shooting sessions, whereas the TX20 suits travelers and casual shooters prioritizing convenience and social media-ready photos.

Sensor and Image Quality: Full-Frame vs. 1/2.3" Sensor Dynamics

At the heart of any camera lies the sensor, the single biggest determinant of image quality. The Sony RX1R is equipped with a full-frame (35.8 × 23.9 mm) 24 MP CMOS sensor, a notable advantage over the TX20’s significantly smaller 1/2.3" (6.17 × 4.55 mm) 16 MP BSI-CMOS sensor.

Why sensor size matters: Larger sensors capture more light and generate superior images, particularly in low light, offering expanded dynamic range, richer color depth, and less noise at high ISO sensitivities. The RX1R’s sensor area (855.62 mm²) dwarfs the TX20’s 28.07 mm² area, allowing it to deliver images with exquisite detail, vibrant tonality, and fine gradations.

Ratings from independent testing underscore this disparity: the RX1R boasts an outstanding DxOmark overall score of 91, color depth of 25.0 bits, and dynamic range of 13.6 EV, enabling photographers to deliver gallery-quality prints and extensive post-processing latitude. The TX20 has never been formally tested by DxOmark, but the small sensor and standard consumer-grade optics limit its image quality to casual use.

Resolution: The RX1R produces 24MP RAW files (6000 × 4000 pixels), while the TX20 shoots 16MP JPEGs at 4608 × 3456 pixels without RAW, impacting detailed editing workflows.

Lens quality synergy: The RX1R incorporates a fixed, premium 35mm f/2 Zeiss Sonnar lens optimized to exploit the sensor’s capabilities, without compromises from zoom mechanics. In contrast, the TX20 offers a 4× optical zoom lens (25-100mm equivalent) with a variable aperture of f/3.5-4.6, trading optical sharpness and aperture speed for versatility and pocket-size.

The absence of an anti-aliasing filter on the RX1R further enhances image resolution and micro-contrast but can introduce moiré in rare patterns, which is an acceptable trade-off for many professionals. The TX20 retains an anti-aliasing filter, common for compact cameras, reducing such artifacts but softening fine detail.

Practical takeaway: For landscape, portrait, or professional use where image quality is paramount, the RX1R’s sensor and lens combo provide unmatched capabilities in this pair. The TX20 is suitable for snapshots and casual video capture but cannot compete with the RX1R’s raw image fidelity.

Autofocus and Shooting Responsiveness: Precision vs. Simplicity

Autofocus systems play a critical role in capturing crisp images, especially in action or changing environments. The RX1R uses a contrast-detection AF system with 25 focus points, including face detection and center-weighted modes, but lacks phase-detection or continuous autofocus capabilities, limiting tracking performance in dynamic subjects. It does feature some tracking modes and selective AF options but requires deliberate use.

Conversely, the TX20 employs contrast AF as well, but fewer details are available about focus points, and it utilizes a single-area or multi-area detection scheme optimized for simplicity rather than speed - an expected compromise in ultracompacts.

The RX1R shoots continuously at up to 5 fps, which while not blazing fast by sports photography standards, is adequate for moderate action. The TX20 nominally offers 10 fps burst shooting but at reduced quality and frame size (generally lower resolution), targeting casual photography.

Face and eye detection: Both cameras support basic face detection autofocus, which aids portrait compositions; however, neither has advanced eye detection AF seen in modern cameras. The RX1R’s focus accuracy, aided by its larger sensor and superior optics, results in better portrait rendition despite slower AF acquisition.

Autofocus precision for macro work: The TX20 has an impressive 1 cm macro focusing distance, ideal for casual close-ups. The RX1R lacks a dedicated macro range but uses manual focus for close subjects and benefits from the sharp 35mm lens with a wide maximum aperture to create effective subject isolation.

Summary: The RX1R prioritizes focus precision and manual control over speed, making it fit for portraits, landscapes, and studio work. The TX20’s autofocus suits spontaneous shooting and convenient focusing but with less reliability and sharpness when precision is critical.

Build Quality and Weather Resistance: Ruggedness vs. Delicacy

The RX1R, despite being a compact, boasts a high-quality metal body, engineered to professional standards though it lacks explicit weather sealing. It is neither waterproof nor dustproof, and users should exercise caution in adverse environments.

The TX20 touts environmental sealing, offering resistance against splashes and dust, complementing its ultracompact form and travel-oriented design. However, it is not waterproof or shockproof, consistent with its consumer category.

Implication for photographers: Those shooting outdoors in unpredictable weather may prefer the TX20 for ruggedness in casual travel or walkabout situations, whereas the RX1R demands more care but rewards with superior build and handling suited to studio or controlled environments.

Display and Viewfinder: Interface Focused on Use Case

Both cameras have fixed, non-articulating 3-inch LCD screens, but with different resolutions and touchscreen capabilities.

The RX1R sports a 1229k-dot Xtra Fine TFT LCD, delivering bright, clear previews ideal for vivid image review and manual focus confirmation. It lacks touchscreen functionality, reflecting its manual control emphasis.

The TX20’s 922k-dot XtraFine TruBlack LCD provides adequate resolution with touchscreen interface, enhancing usability for camera novices or on-the-go shooting, although the lower resolution and smaller dynamic range limit outdoor visibility slightly.

Neither camera includes a built-in viewfinder; the RX1R offers an optional external electronic and optical viewfinder that pairs magnificently for classic framing and exposure control, while the TX20 has no finder option, relying on the rear screen.
