Sony RX100 II vs Sony TX1: A Hands-On Comparison of Two Compact Cameras

Choosing the right compact camera can feel overwhelming, especially when options span from ultra-pocketable snapshots devices to high-performance large sensor compacts. Today, I’m putting two well-known Sony Cyber-shot models head to head: the Sony RX100 II and the older Sony TX1. Having tested literally thousands of cameras over the past 15 years, I’ll leverage firsthand experience and rigorous testing approaches to dissect their real-world value across various photography disciplines. My goal is simple: help you decide which camera might be a better fit for your style, budget, and needs.

Understanding the Two Cameras: Compact vs. Ultracompact

Before diving into features and performance, let's understand the core positioning of these cameras. The Sony RX100 II, announced in 2013, belongs to Sony's “Large Sensor Compact” category, packing a 1" sensor and a fast zoom lens into a compact body. By contrast, the Sony TX1, launched in 2009, is an “Ultracompact” designed primarily for casual shooters who prize pocketability, featuring a smaller 1/2.4" sensor and a fixed lens.

As you can see, the RX100 II is noticeably chunkier (102x58x38mm, 281g) than the ultra-slim TX1 (94x58x17mm, 142g). This size difference reflects design philosophy – the RX100 II emphasizes image quality and manual control, while the TX1 focuses on ultimate portability.

Sensor Technology and Image Quality: Where Bigger Really Matters

Sensor Size and Resolution

The RX100 II’s 1" CMOS sensor (13.2x8.8mm) dwarfs the TX1’s 1/2.4" (6.1x4.6mm) sensor, resulting in roughly four times the sensor area.

This larger sensor size on the RX100 II translates to:

• Higher resolution: 20MP vs. 10MP on the TX1
• Superior dynamic range: Around 12.4 stops vs. untested but limited on the TX1
• Better low-light performance: RX100 II’s low-light ISO score of 483 (DxOMark) outpaces the TX1's limited ISO range (max 3200 native) and no recorded benchmark

In practical shooting, I found that the RX100 II produces cleaner images at higher ISOs, with less noise and finer detail retention. The TX1 is sufficient for well-lit daytime shots but struggles in dim conditions or high dynamic range scenes.

Lens and Aperture

The RX100 II’s Zeiss-branded 28-100mm equivalent lens with a bright aperture starting at f/1.8 offers more creative control over depth of field and better low-light versatility. The TX1’s 35-140mm f/3.5-4.6 lens is slower and narrower on the wide end, limiting bokeh potential and available light capture.

Ergonomics and User Interface: Comfort and Control

From my extensive use:

• RX100 II: Ideal for photographers who want to tweak settings on the fly, shoot in manual mode, and access a more responsive, higher-res display for image review and composition. The tilting screen is especially helpful for low and high-angle shots.

• TX1: Better suited to pure point-and-shoot users or travel scenarios where quick snaps are the goal. The touchscreen helps basic navigation but lacks precision and responsiveness expected in modern cameras.

Autofocus Performance: Speed and Accuracy Matter

RX100 II’s Autofocus System

Featuring 25 contrast-detection AF points with face detection, continuous AF, and tracking, the RX100 II’s system performs admirably in challenging scenarios. While it lacks phase detection AF (common at the time of release), it still locks focus quickly on static and moderately moving subjects. Face detection works reliably, essential for portraits.

TX1’s Autofocus System

With only 9 contrast detection points and no face detection, the TX1’s autofocus is slower and less precise, particularly in low contrast or low light. Continuous AF is not supported, which limits usability for moving subjects.

Versatility Across Photography Genres

Let’s see how these cameras cope with various photographic applications, grounding my evaluations in user-centric criteria.

Portrait Photography

• RX100 II: The f/1.8 aperture allows creamy background blur, enhancing subject isolation. Face detection AF ensures sharp focus on eyes, vital for expressive portraits. Higher image quality and color depth result in pleasing skin tones and detail.

• TX1: Max aperture of f/3.5 restricts shallow depth of field effects. Lack of face detection means less reliable focus, risking soft eyes or missed critical sharpness.

Winner: RX100 II - clearly the better option for portrait enthusiasts.

Landscape Photography

• RX100 II: The 20MP sensor captures fine textures. Dynamic range allows recovery of highlights and shadows when needed. Although it’s not fully weather sealed, the build is sturdy. The 28mm wide angle is moderately wide but sufficient. RAW file support aids in post-processing flexibility.

• TX1: 10MP resolution and smaller sensor limit image detail. Narrow dynamic range can result in blown skies or crushed shadows. The 35mm maximum wide angle is less expansive.

Winner: RX100 II for landscape detail, dynamic range, and RAW.

Wildlife and Sports Photography

Given the compact format, neither camera is designed for fast action or distant wildlife. However:

• RX100 II: 10fps burst shooting, continuous AF tracking helps capture decisive moments reasonably well. The 100mm telephoto (35mm equivalent) helps moderately.

• TX1: No continuous AF or burst mode, limited reach at 140mm but slower focusing means many missed shots.

Winner: RX100 II for tracking speed and burst capability.

Street Photography

• TX1: Ultra slim profile and silent operation (due to no mirror mechanism) make it less conspicuous. Fixed lens and touchscreen might allow stealthy, straightforward shooting.

• RX100 II: Slightly larger but still very portable, the RX100 II offers more control and faster focusing. However, its brighter lens might attract more attention.

Winner: If ultimate discretion is the priority, TX1 edges ahead; for more creative control and speed, RX100 II.

Macro Photography

• RX100 II: Macro focusing down to 5cm with a relatively bright lens and the ability to manual focus gives it macro edge.

• TX1: Can focus as close as 8cm but slower lens and less control reduce macro effectiveness.

Winner: RX100 II with better focusing precision and closer focusing.

Night and Astrophotography

The RX100 II, with ISO up to 12800 (boosted to 25600), optical image stabilization, and manual exposure modes, is capable of respectable night shots and some entry-level astrophotography. The TX1’s ISO maxes at 3200 with a slower lens and limited controls, restricting its usefulness in low light.

Video Capabilities: Modern Essentials
