Sony TX30 vs Sony TX7: A Detailed Comparison of Two Compact Contenders

In the realm of ultra-compact cameras, Sony has long built a reputation for creating feature-packed, pocketable shooters that appeal to casual snapshooters and discerning enthusiasts alike. Today, we're diving deep into a nuanced comparison between two of Sony’s older Cyber-shot models: the Sony TX30 (2013) and its predecessor, the Sony TX7 (2010). At face value, they share a lot in common - compact bodies, fixed zoom lenses, and modest price points - but as with many cameras separated by a few years, the devil is always in the details.

After personally handling these cameras over extended shooting sessions, testing across various photographic disciplines, and analyzing their technical specifications, this article will serve as your comprehensive guide to understanding which might best suit your photographic needs. Whether you're into travel snaps, portraiture, or just want a reliable second camera, I’ll break down performance, usability, image quality, and value - all based on hands-on experience, not just datasheets.

Let’s get started by taking an overall look at their physical presence and control layout.

Form and Function: Handling and Ergonomics

One of the first things I noticed jumping between the TX30 and TX7 was their remarkably compact forms, true to Sony’s Cyber-shot ultracompact ethos. Both cameras slip easily into a jacket pocket or a small bag - welcome freedom for on-the-go photography.

Size and Weight: The TX30 measures 96x59x15 mm and weighs a mere 141 g, while the TX7 is slightly larger and thicker at 98x60x18 mm and 149 g. This makes the TX30 fractionally slimmer and lighter, an advantage if pocketability is your top priority.

Grip and Handling: Both cameras lack dedicated grips, which is typical in this category, but the TX30's more streamlined body and rounded edges make it marginally easier to hold securely. The TX7 feels a bit chunkier but offers thicker handrails along the front edges, which might aid those with larger hands.

Controls: Here the differences emerge. The TX7 features a traditional button layout with a tactile four-way directional pad, dedicated zoom rocker, and mode dial-like control. Meanwhile, the TX30 streamlines controls with fewer physical buttons in favor of a touchscreen interface - an OLED touchscreen to be exact.

The touchscreen functionality of the TX30 adds modern flair and accessibility, especially for portrait shooters wanting quick focus adjustments via touch. The TX7's physical buttons, however, afford more confidence for rapid-fire shooting situations where tactile feedback is critical - say, in outdoor or sports environments where looking at the screen is inconvenient.

Screen Characteristics: The TX30’s 3.3-inch OLED touchscreen boasts 1229k dots, offering more vibrant colors, higher contrast, and better outdoor visibility than the TX7’s 3.5-inch LCD at 921k dots - which is functional but noticeably more muted. Although slightly smaller, the TX30’s display feels more modern and responsive.

In sum, ergonomically, if you favor minimalist, intuitively touchscreen-controlled cameras, the TX30 edges ahead. For those who prefer physical controls and larger screens, the TX7 remains a viable choice despite its vintage styling.

Under the Hood: Sensor Tech and Image Quality

A camera’s sensor truly defines what it can do, and here’s where our two contenders differ significantly. I took both into varied lighting situations - from bright daylight landscapes to challenging indoor settings - and subjected their images to meticulous side-by-side pixel peeping and real-world evaluations.

Sensor Size and Resolution:

• Sony TX30: Utilizes a 1/2.3-inch BSI-CMOS sensor, measuring 6.16 x 4.62 mm (28.46 mm²), with a resolution of 18 megapixels.
• Sony TX7: Also uses a similar 1/2.4-inch BSI-CMOS sensor, slightly smaller at 6.104 x 4.578 mm (27.94 mm²) but offers only 10 megapixels.

At first blush, the TX30’s higher resolution gives it a potential edge for detail and cropping flexibility. However, higher pixel counts on small sensors often come with trade-offs.

Image Quality in Practice: The TX30’s 18 MP sensor produces sharper images with more detail in well-lit conditions, making it excellent for landscapes and portraits where fine texture matters. However, this comes at the expense of increased image noise starting at ISO 400, becoming pronounced at ISO 800 and above.

The TX7’s lower-resolution 10 MP sensor, in contrast, handles high ISO better, preserving image integrity up to ISO 1600 with less noise, thanks to larger individual pixels. So if you often shoot indoors, in low light, or at night, the TX7 might yield smoother images.

Dynamic Range: Both cameras lack raw capture support, which limits post-processing latitude and dynamic range recovery. Technically, the TX30’s sensor shows a slightly wider dynamic range due to newer sensor technology, but in practical shooting, clipped highlights and crushed shadows require careful exposure management in both.

Lens and Autofocus: Versatility and Speed

The lens system is fixed on both cameras, emphasizing compactness over versatility, but the optical range and autofocus behavior differ.

Focal Length:

• TX30: 26-130 mm equivalent (5× zoom), aperture f/3.5-4.8
• TX7: 25-100 mm equivalent (4× zoom), aperture f/3.5-4.6

The TX30 offers a longer telephoto reach, extending your framing options particularly for portraits and wildlife snapshots, although the aperture narrows slightly at the tele end.

Macro Focus Distance:

• TX7 supports extremely close macro shooting down to 1 cm, impressively close for an ultracompact, enabling detailed close-ups of flowers, insects, and textures.
• TX30 does not list a dedicated macro focus distance, suggesting less capability for extreme close focusing.

Autofocus System:

• TX7 features a contrast-detection AF system with nine focus points, center-weighted metering, and basic face detection capability, plus a touch-enabled AF system.
• TX30 eschews autofocus points entirely, lacking phase-detection or contrast-detection AF, relying on a simpler fixed focus or single-point AF controlled by touchscreen. No face or eye detection is available.

This makes the TX7 significantly more versatile and reliable in achieving sharp focus quickly in a variety of shooting scenarios, including tricky macro and fast-moving subjects.

Shooting Experience: Burst Rate, Shutter, and Stabilization

Continuous Shooting: Both cameras offer 10 frames per second burst shooting, theoretically beneficial for fleeting street moments or fast-action subjects.

From personal trials, however, the TX7's buffer fills faster due to lower RAM, meaning shorter continuous shooting bursts before lag sets in. The TX30, with updated internal processing, sustains the 10 fps longer albeit with slightly more conservative JPEG compression.

Shutter Speed: The shutter speed ranges (TX7: 2 - 1600, TX30: 4 - 1600) are similar, but the TX7 can select a slower 2-second shutter, beneficial for low-light and night photography.

Image Stabilization: Both rely on optical image stabilization (SteadyShot), crucial for handheld macro, travel, and telephoto shots. In practice, they perform similarly, providing about 2–3 stops of shake mitigation. The TX30's stabilization feels a touch more refined, likely due to incremental improvements in hardware.

Build Quality and Durability

The TX30 boasts environmental sealing, promising protection against dust and minor splashes. This makes it more trustworthy for travel and outdoor use in less-than-ideal weather, such as light rain or dusty trails.

The TX7 does not offer such sealing; it requires more careful handling around moisture and debris.

Both are compact and made of plastic and metal composites - durable for casual use but not ruggedized or shockproof.

Video Capabilities: Moving from Stills to Motion

Both cameras can record Full HD video at 1920x1080 resolution, with 60 fps (TX30) or 60 fps/30 fps (TX7), providing smooth motion capture suitable for family moments or casual filmmaking.
