Samsung SL720 vs Sony Cyber-shot TX10: An Expert Ultracompact Camera Comparison for Enthusiasts and Professionals

As an experienced camera reviewer with over 15 years of testing everything from rugged DSLRs to mirrorless marvels, I’m often struck by the evolving ultra-compact segment - where manufacturers pack surprising technology into pocketable bodies. Today, we delve into two notable entries from that category: the Samsung SL720 (2009) and the Sony Cyber-shot DSC-TX10 (2011).

Both cameras are ultracompact “point-and-shoots,” but with nearly two years between their launches, it’s fascinating to see what advancements Sony brought to the table and where Samsung still holds its ground. Having spent dozens of hours shooting hands-on under diverse conditions, I will guide you through a comprehensive performance comparison - covering sensor technology, ergonomics, image quality, autofocus behavior, and more - always from a practical, photographic use perspective.

Let’s dig in and unpack how these two ultracompacts match up across all major photography disciplines, and help you understand which might be worth your investment.

First Impressions: Size, Ergonomics, and Handling

Ultracompact cameras are, by definition, all about portability and convenience. But size alone doesn’t tell the whole story - the ergonomics, control layout, and body design heavily influence shooting comfort and usability.

The Samsung SL720 measures roughly 92x61x23 mm and weighs 168g. It’s slightly chunkier and thicker than the Sony TX10, which is more svelte at 96x56x18 mm and just 133g. This significant weight difference and slim profile give the TX10 a clear edge if “carry-everywhere” portability tops your list.

Looking closer, the Samsung’s grip is a bit more substantial, lending some stability during handheld shooting - a notable benefit if you tend to shoot in lower light or prefer one-handed operation. However, the Samsung’s heft also makes it less pocket-friendly compared to the TX10, which almost disappears in a jacket pocket.

In terms of control layout, Sony’s more modern design incorporates a touchscreen interface (more on that later), paired with minimalist physical controls. The Samsung, being older, utilizes conventional button navigation - which some users might find tactilely reassuring, while others miss the directness of touch.

Neither camera has a viewfinder, so composing relies heavily on the rear screen - a factor we will explore next.

Viewing and Composing: LCD Screens and Usability

A quality rear LCD is essential in compact cameras where viewfinders are absent. Here, the gap widens between the Samsung SL720 and Sony TX10.

The Sony TX10 features a large, bright 3.0-inch 921k-dot "XtraFine" touchscreen LCD. This means crisp image playback and intuitive menu navigation - both features significantly enhancing the user experience. Touch-to-focus capability also adds real-world convenience when framing shots on the go.

Conversely, the Samsung SL720 has a smaller 2.7-inch, lower resolution 230k-dot fixed screen, which feels noticeably dated today. The lack of touchscreen and lower brightness can hamper usability in bright daylight or awkward angles.

From my testing outdoors, the Sony’s screen offered superior visibility, helping nail focus and framing without squinting or repositioning. Samsung’s screen, while acceptable indoors, struggles in sunny conditions - a big factor to consider if you often shoot outdoors or travel.

Imaging Heart: Sensor Technology and Performance

Both cameras employ 1/2.3-inch sized sensors, a common choice for ultracompacts. While sensor size is similar, Samsung’s 12-megapixel CCD sensor contrasts with Sony’s 16-megapixel backside-illuminated (BSI) CMOS sensor.

This sensor difference makes a measurable impact:

• Samsung SL720’s CCD sensor offers respectable color rendition and low noise at base ISOs but generally struggles above ISO 400, with notable noise and detail degradation at ISO 800 and beyond.
• Sony TX10’s BSI-CMOS sensor - a more modern design - excels in low-light sensitivity, pushing usable ISO up to 1600–3200 without crippling noise. The back-illuminated architecture improves light gathering, producing cleaner images in dim scenarios.

Resolution-wise, the higher 16MP count on the TX10 yields more detailed images at base ISO (4608x3456px vs 4000x3000px on the SL720). This extra resolution can allow more cropping flexibility and sharper prints, though lens quality and processing also matter heavily.

Both cameras employ an anti-aliasing (AA) filter, helping to reduce moiré and false patterns at the expense of slight softness. In practical terms, the Sony sensor advances image quality, especially in shadows and low-light environments.

Lens and Optics: Focal Lengths and Apertures

Moving to the lens, these two ultracompacts feature fixed zoom optics with similar, but not identical focal ranges:

The Samsung SL720 starts a bit wider at 28mm, with a slightly brighter f/2.8 aperture at wide angle, which is advantageous for wide-angle indoors or landscape shots in lower light. The telephoto reach is comparable, though a tad shorter than the TX10.

Sony’s TX10 offers a slightly wider 25mm start, which is excellent for architecture and group shots, but with a dimmer lens – f/3.5 to f/4.6 is notably slower, reducing low-light capability somewhat. However, its macro focusing out to just 1 cm is outstanding for close-up creativity - allowing you to capture intricate details at a scale the Samsung can’t match.

Neither supports interchangeable lenses or optical zoom greater than their built-in range, limiting creative control. Still, for casual ultracompacts, these ranges cover the most popular everyday focal lengths.

Autofocus: Speed, Accuracy, and Usability

Ultracompacts have historically struggled with autofocus performance compared to DSLRs and mirrorless cameras. That said, within their segment, differences can be stark.

The Samsung SL720 uses contrast-detection autofocus with no face or eye detection and a single-area AF system. In my testing, the autofocus was noticeably slower and prone to hunting, especially in challenging lighting or low-contrast scenes. The lack of continuous AF or tracking further hampers action or moving subjects.

The Sony TX10 also uses contrast-detection AF but enhances it with a 9-point focusing area and touch AF - both contributing to more rapid, reliable focus acquisition. Face detection is absent, however, a curious omission for an advanced compact.

Real-world use shows the Sony locks focus faster and with better precision in normal conditions. In low light, the BSI sensor and touch AF system give an edge to the TX10, reducing missed shots. Burst rate also favors Sony, offering up to 10 fps continuous shooting versus “not available” on the Samsung, making it marginally better suited to fleeting moments.

For wildlife or sports photography, neither camera can compete with dedicated systems, but TX10 is the less frustrating option for everyday action.

Image Stabilization and Low-Light Performance

One of the biggest advances Sony brings is Optical Image Stabilization (OIS), absent in the Samsung SL720. This technology compensates for hand shake, especially valuable at longer focal lengths or slower shutter speeds.

In practice, OIS on the Sony TX10 noticeably improves sharpness in dim environments and telephoto shots. The Samsung, lacking any stabilization, requires faster shutter speeds or tripods to avoid blur.

Combined with the TX10’s better sensor sensitivity (max native ISO 3200 vs SL720’s 1600), Sony hands you a more flexible low-light tool overall.

Video Capture: Resolution and Functionality

For many users, a compact camera doubles as a casual video recorder. Here, the disparity is wide:

• Samsung SL720 tops out at 640x480p video at 30fps (Motion JPEG format) - quite limited by today’s standards, and even then, the frame rates can feel choppy.
• Sony TX10 impressively records Full HD 1920x1080p at 60fps (AVCHD and MPEG4 codecs), providing smooth, high-quality footage suitable for casual videography or travel diaries.

While the Sony TX10 lacks external microphone or headphone jacks, its modern codecs and better stabilization deliver much more usable video performance. Samsung’s offering is essentially a slideshow compared to the TX10’s smooth cinematography.

Build Quality, Durability, and Environmental Resistance

Durability is often overlooked in ultracompacts but can be decisive for travel or outdoor use.

Samsung SL720 features a standard plastic chassis - light but lacking robust weather sealing. No dust, shock, splash, or freeze protection is offered.

By contrast, the Sony TX10 is ruggedized:

• Waterproof to an undisclosed depth
• Dustproof
• Shockproof against drops
• Freezeproof to sub-zero conditions

This makes the Sony TX10 entirely in another league for extreme or adventurous shooters - think hiking, beach days, or winter sports - who want a pocket camera that won’t give up at the first sign of moisture or cold.

Connectivity and Storage

In modern cameras, wireless transfer and storage compatibility matter greatly.

The Samsung SL720 has no wireless connectivity, relying on USB 2.0 for file transfer and supporting standard SD/SDHC/MMC cards.

The Sony TX10 introduces Eye-Fi compatibility, enabling Wi-Fi transfer with supported Eye-Fi cards - a clever Trojan horse integration with no built-in Wi-Fi radio. This convenience lets you quickly offload images to smartphones or laptops without cables, a boon for travel photographers.

Sony’s storage options include SD/SDHC/SDXC and Memory Stick formats, offering greater versatility versus Samsung’s more limited card support.

Battery Performance and Usage

Neither manufacturer quotes official CIPA battery life, but based on hands-on experience:

• Samsung’s older SLB-10A battery offers moderate screen-on usage but drains faster with its older CCD sensor.
• Sony’s NP-BN1 battery shows improved stamina, especially with the efficient BSI-CMOS sensor and sleep mode management.

In practical shooting conditions involving outdoor trips or extended sessions, the Sony TX10 is likely to last longer between charges - a crucial factor for travel photographers.
