Samsung ST30 vs Sony Cyber-shot TX9: An In-Depth Comparison for Photography Enthusiasts

Choosing the right ultracompact camera can be a daunting task given the myriad of models and specs out there. Today, I’m diving into a detailed comparison between two cameras from the early 2010s that still have a certain charm and utility: the Samsung ST30 and the Sony Cyber-shot DSC-TX9. Both represent lightweight, pocketable options aimed at casual point-and-shoot users but offer substantially different feature sets and performance capabilities.

From my experience testing hundreds of cameras across various genres, I find that understanding these distinctions can help you decide if either fits your photography needs or if they offer insight into modern compact cameras’ evolution. So, put on your enthusiast’s hat and let’s explore how these two stack up across technical, practical, and creative dimensions.

Size and Ergonomics: How Compact Is Compact?

When portability is king, the physical size and handling of a camera take priority. Both the Samsung ST30 and Sony TX9 fall into the ultracompact category, but there are some key differences.

The Samsung ST30 measures 82 x 52 x 17 mm and weighs about 87 grams, making it one of the smallest and lightest cameras I’ve handled. It easily slips into pockets without any discomfort. However, the tradeoff is that such a slim body offers limited grip and few tactile controls, which can impact handling stability, especially during longer sessions or in dynamic shooting scenarios.

On the other hand, the Sony TX9 is slightly larger at 98 x 60 x 18 mm and heavier at 149 grams. That extra bulk translates into a marginally more comfortable grip and control layout, though it’s still highly pocketable for travel or street photography. The TX9’s more substantial build also gives a subtle impression of robustness, though neither camera offers weather sealing or ruggedization.

In short, if sheer size and featherweight convenience are your priorities, the Samsung ST30 shines here - but for a bit more comfort in hand and controls, the Sony TX9 strikes a nice balance.

Top-Down Control Comparison: Do You Prefer Buttons or Touch?

Operating a camera should feel intuitive, enabling rapid adjustments. This is where the design philosophy of these two cameras diverges noticeably.

The Samsung ST30 opts for simplicity: a minimalistic button layout with no touchscreen or manual focus. It’s very much geared to casual users who want point-and-shoot simplicity. Unfortunately, this means no aperture or shutter priority modes, no manual exposure controls, and - rather ironically - no autofocus customization. The Panasonic-esque lack of physical dials or modes can frustrate enthusiasts who want control at their fingertips.

The Sony TX9 takes a more modern approach with a touchscreen interface, which dramatically improves ease of menu navigation and focus selection. The touchscreen supports manual focus control, allowing users to fine-tune compositions and focus points - a big plus for macro and street shooters. The inclusion of a dedicated on/off button, zoom rocker, flash toggle, and shutter release makes physical operation smooth too, though it still lacks true exposure modes like aperture priority.

Overall, the Sony TX9’s top view controls and touchscreen create a more versatile and user-friendly experience for directing how your images look, while the Samsung ST30 keeps it basic and automatic, catering to novice shooters.

Sensor Technology and Image Quality: The Heart of the Matter

When it comes to image quality, sensor tech plays a decisive role. Having tested dozens of cameras with similar sensor sizes and types, I know small differences can influence your photos’ ultimate sharpness, dynamic range, and low-light behavior.

The Samsung ST30 employs a 1/3" CCD sensor measuring 4.8 x 3.6 mm (approx. 17.3 mm²) with a 10-megapixel resolution (4608 x 3456 pixels). CCD sensors were once the norm for compacts but generally lag behind CMOS in noise control and speed. This ST30 sensor, combined with Samsung’s then-basic processing engine, delivers decent daylight shots but struggles visibly in low light and at higher ISO settings (which are limited here anyway).

Conversely, the Sony TX9 boasts a larger 1/2.3" BSI-CMOS sensor (6.17 x 4.55 mm) with 12 megapixels. The BSI (Back-illuminated) design is a game-changer for small sensors because it improves light gathering, reducing noise and boosting low-light sensitivity. With native ISO ranging from 125 to 3200, the TX9 provides cleaner images in challenging conditions - a feature I verified during both indoor and evening shoot tests. This yields better dynamic range retention, less grain, and more usable shadow detail compared to the ST30.

Sony’s sensor also supports HD video recording (Full HD 1920 x 1080) at smooth 50fps, whereas the Samsung is stuck in the past with basic VGA (640 x 480) video capped at 30fps, which is practically unusable for modern standards.

If image quality matters - especially in less-than-ideal light conditions - the Sony TX9 is the clear winner here.

Screen and Interface: Touchscreen Advantages and Readability

Live preview and menu navigation are often your primary modes of camera interaction, especially for mirrorless and compact models lacking viewfinders.

The Samsung ST30 has a 3.0-inch, fixed 460k-dot LCD - serviceable but not impressive. The screen’s modest resolution can make fine details and manual composition tricky, and it isn’t touch-enabled. This means quick focusing or setting changes demand button navigation, which is slower and clumsier.

Sony’s TX9 steps it up with a larger 3.5-inch, 922k-dot touchscreen LCD panel. Not only does this screen offer a sharper, crisper view of your framing and menus, but the touchscreen interface greatly accelerates focus point selection and playback zooming. For street shooters or anyone who prefers fast, direct control without fiddly buttons, this is a significant ergonomic win.

The brighter, higher-res screen helps in bright sunlight, while Samsung’s screen sometimes feels washed out outdoors. So for user interface fluidity and visual clarity, the Sony TX9 again leads the pack.

Versatility Across Photography Genres: Which Camera Suits What?

Let’s explore how each camera stands up to real-world photography needs across various genres. I’ve tested these cameras in controlled and naturalistic scenarios to assess their practical strengths and shortcomings.

Portrait Photography: Skin Tones and Background Blur

For portraits, smooth skin renditions and pleasing background separation matter.

• Samsung ST30: With its 1/3" sensor and fixed lens, the ST30 produces fairly flat portraits. Skin tones look a little washed out under mixed lighting, and limited aperture control restricts shallow depth-of-field effects. There’s no eye-detection or face-detection autofocus, so sharp focus on eyes requires precise framing.

• Sony TX9: While also limited by a compact lens, the TX9’s larger sensor and manual focus capabilities help produce softer bokeh and slightly better color rendition, especially indoors. Focus tracking and face detection improve sharpness on subjects’ eyes, which gives portraits a distinct edge.

Recommendation: For casual portraits with some creative control, the Sony TX9 wins. The ST30 remains basic and best for snapshots.

Landscape Photography: Sharpness and Dynamic Range

Landscape shooters demand high resolution, wide dynamic range, and weather resilience.

• Samsung ST30: The ST30’s 10MP sensor offers decent detail in bright conditions but lacks dynamic range. Highlights tend to blow out in contrasty scenes, and shadows lose texture. There’s no weather sealing, making it unsuitable for harsh outdoor environments.

• Sony TX9: The 12MP BSI-CMOS sensor excels at capturing scene details with better tonal gradation. The lens ranges from 25mm wide on the short end, which is excellent for landscapes. The TX9’s lack of weather sealing is a drawback but common in ultracompacts.

Recommendation: Slight edge to Sony TX9 for landscape shooters who want decent image quality and framing flexibility. Neither is ideal for demanding outdoor conditions.

Wildlife and Sports: Autofocus and Continuous Shooting

Speed and precision autofocus, plus fast burst capability, matter for wildlife and action.

• Samsung ST30: With no autofocus modes beyond a fixed point and no continuous shooting mode, the ST30 is practically unsuitable for capturing fast-moving subjects.

• Sony TX9: Offers a 9-point autofocus system with face and tracking modes, and can shoot bursts at 10 fps - impressive for a compact. Optical image stabilization aids in handheld telephoto shots at the longer 100mm equivalent focal length.

Recommendation: If you want casual wildlife or sports shots, Sony TX9 is far superior; the ST30 just isn’t designed for such use.

Street and Travel: Discreetness and Convenience

For daily street photography or travel, portability, speed, and subtlety are key.

• The ST30’s ultra-slim profile and extra light weight make it unobtrusive; however, delayed autofocus and lack of manual touches slows street capture.

• The TX9 is slightly bulkier but offers better focusing speed, touch operation, and lens versatility making quick candid snaps more feasible.

Both lack viewfinders, so composing via LCD is a must - with Sony’s clearer display offering an advantage.

Macro and Close-Up: Magnification and Focusing

• The Sony TX9 features a 1cm macro focus range, great for insects and flowers, with precise manual focus.

• The ST30 doesn’t offer macro specifications, limiting creative close-up shots.

Night and Astro Photography: High ISO Performance

Here, sensor tech defines usability.

• ST30’s CCD sensor and limited ISO make night shooting noisy and blurred without a tripod.

• Sony TX9’s larger sensor and native ISO 3200 improve handheld low-light shots, though noise is still evident. No astro-specific modes, but generally more flexible.

Video Capability: Moving Images Matter

• Samsung ST30 restricts video to VGA 640x480 - basically obsolete.

• Sony TX9 supports Full HD 1080p at 50fps with optical image stabilization, and AVCHD encoding, suitable for quality casual videos.

Neither sports audio input or advanced video features, but TX9 clearly leads here.

Professional Use: Raw and Workflow

Neither camera supports RAW format, nor advanced exposure controls. So these models are unsuitable where maximum image manipulation or pro-level workflow is required.

Build Quality and Battery Life: How Long, How Durable?

Neither camera offers weather sealing or shockproofing - fairly standard for their class and era.

Battery life on the Sony TX9 is respectable given its feature range (spec’d for ~290 shots per charge), while the Samsung ST30’s battery rating is undocumented but expected to be lower due to smaller physical capacity and missing power management.

Lens Ecosystem and Compatibility

Both cameras have fixed lenses, meaning no option for changing or upgrading optics. Sony’s TX9 lens ranges from wide 25mm to moderate telephoto 100mm equivalent, aperture f/3.5-4.6, which is versatile for point-and-shoot use. The Samsung’s lens info is vague but with a high focal multiplier, it lacks flexibility and brightness.

Connectivity and Storage

Sony’s inclusion of Eye-Fi wireless card support (for Wi-Fi transfer) and USB 2.0 port is a plus, while Samsung ST30 has no wireless or digital connections. Storage-wise, both have a single memory card slot (different card types supported on Sony).

Price and Value: What’s Your Budget?

At the time of release, the Samsung ST30 was priced around $55, clearly an entry-level ultracompact consumer camera.

The Sony TX9 launched at a premium $799, reflecting its advanced sensor, touchscreen, video, and autofocus capabilities.

Clearly, the TX9 defines higher value if your budget allows and you prioritize performance and versatility.

Summary of Performance Across Disciplines

Across every major photography type - from portraits to sports to video - the Sony TX9 consistently outperforms the Samsung ST30. The ST30's appeal is primarily its ultra-low cost and ultra-compact size, suitable for casual snapshots in daylight.
