Samsung SL720 vs Sony Cyber-shot DSC-TX20: The Ultimate Ultracompact Camera Showdown

Choosing the right ultracompact camera can be surprisingly challenging. Two popular models that continue to attract attention are the Samsung SL720 (also known as the PL70) and the Sony Cyber-shot DSC-TX20. Despite their shared category, these cameras target slightly different users with distinct strengths and weaknesses. Drawing on extensive hands-on testing and years of comparative experience with ultracompacts, I’ll take you through a detailed, user-focused comparison that covers all major photographic use cases and technical considerations.

If you’re evaluating these two for your next purchase, this article will give you a clear understanding of where each shines, and where you might want to manage expectations.

Physical Design and Handling: Compact, But How Comfortable?

When it comes to pocketable cameras, size and handling can make or break the experience. Neither camera offers an electronic viewfinder, emphasizing their slim, grab-and-go design ethos.

• Samsung SL720 measures 92 x 61 x 23 mm and weighs 168g.
• Sony TX20 comes in slightly slimmer at 96 x 56 x 18 mm and lighter at 133g.

Though the Sony is a bit smaller and lighter, the Samsung’s slightly deeper body provides better grip for extended shooting sessions - an important consideration I noticed when spending a full day using each. The Samsung’s rounded edges also aid comfort, while the Sony’s sleek, flat design prioritizes ultra-slim portability.

Control wise, both lack many dedicated buttons due to their ultracompact nature. However, the Sony gains an advantage with a touchscreen interface, while the Samsung’s controls feel more conventional, with physical buttons but no touchscreen capability. The Sony’s touchscreen is responsive and intuitive after a little practice, making quick AF point selection and menu navigation smoother.

Sensor and Image Quality: CCD vs BSI-CMOS – What’s the Difference?

Under the hood, these cameras take notably different technical routes that impact image quality:

What this means in practice:

• The Sony’s BSI-CMOS sensor has a significant edge in low light performance and dynamic range, thanks to its back-illuminated design allowing more light capture per pixel.
• Higher native ISO (up to 3200 vs 1600) means the Sony sustains better image quality in dim conditions without degrading into noise.
• The Sony's modestly higher resolution offers more detail and cropping flexibility.
• The Samsung’s aging CCD sensor is less efficient, yielding noisier images above ISO 400 to 800.

In direct side-by-side tests - shooting landscapes and indoor portraits - I found the Sony TX20 consistently produces cleaner, sharper images with better color fidelity and less noise at higher ISO levels. The Samsung images, while usable in good light, start showing softness and grain earlier.

Screen and User Interface: Touchscreen Triumph vs Simplicity

Both cameras opt out of viewfinders, relying on LCD screens for composition and review:

• The Samsung SL720 features a 2.7-inch, 230k-dot fixed screen.
• The Sony TX20 upgrades to a 3-inch, 922k-dot XtraFine TruBlack TFT LCD touchscreen.

In practical use, the Sony’s high-resolution touchscreen vastly improves framing accuracy and playback clarity. Its TruBlack technology enhances contrast in bright conditions, a common pain point for compact cameras.

The Samsung’s lower-resolution screen is adequate but less detailed and less responsive during quick setting adjustments - especially in bright highlight conditions where reflections hamper visibility.

Autofocus and Shooting Performance: Speed and Accuracy Matter

Ultracompacts traditionally don’t impress in autofocus (AF), but there’s a gap between these two:

• The Samsung uses contrast-detection AF only with a single AF operation mode.
• The Sony TX20 offers more sophisticated AF capabilities:
  • Contrast-detection AF with face detection
  • AF tracking
  • Selective AF point choice via touchscreen

Burst shooting is another differentiator:

• Samsung does not specify continuous shooting speed (essentially negligible).
• Sony boasts a 10 frames per second burst at full resolution, excellent for catching fleeting moments.

I tested both on a sunny afternoon trying to capture moving subjects and street scenes. The Sony’s AF was decisively quicker to lock focus - especially on faces - and the burst mode enabled me to capture several usable frames in quick succession. The Samsung’s budget AF struggled with speed and accuracy on moving subjects.

Practical Photography Use Cases: Strengths and Limitations

Let’s break down how each camera delivers across major photography genres and scenarios:

Portrait Photography

• Samsung SL720 falls short: no face or eye detection, limited AF control, and older sensor technology means less color and detail finesse.
• Sony TX20 shines:
  • Face detection enabled fast, reliable focus on subjects at various distances.
  • BSI-CMOS sensor renders skin tones naturally.
  • Optical image stabilization (OIS) helps reduce blur in indoor portraits.

Winner: Sony TX20 for superior AF, stabilization, and image quality.

Landscape Photography

• Samsung offers 12MP resolution and a max focal range of 28-102mm equivalent (3.6x zoom).
• Sony offers 16MP with 25-100mm equivalent (4x zoom), giving slightly wider framing and more detailed images.

Neither camera has weather sealing except the Sony, which does include some environmental sealing to protect against dust and moisture - valuable in outdoor conditions.

Sony’s better sensor and improved dynamic range provide more vivid, detailed landscapes with less noise in shadows, making it preferable for outdoor shooters.

Wildlife and Sports Photography

Ultracompacts are rarely ideal here due to limited telephoto reach and sluggish AF, but let’s examine:

• Both have modest zoom: Samsung at 102mm max, Sony maxes at 100mm.
• Samsung lacks burst or rapid AF.
• Sony offers fast continuous shooting at 10 fps and AF tracking.

Sony’s AF tracking and high frame rate are clear assets, allowing you to capture quick wildlife or sports action decently close-up. Samsung’s specs and tests prove inadequate for these genres.

Street Photography

Candid shooting benefits from discreetness, speed, and portability:

• Sony’s smaller, lighter body and touchscreen interface aid rapid shooting with less fuss.
• Samsung’s bigger size is still pocketable but more noticeable.
• Both cameras have quiet shutter modes absent, but Sony’s faster specs reduce delay between shots.

I found the Sony better suited for street photography thanks to its intuitive AF and controls that enable quick shooting and on-the-fly focusing.

Macro Photography

• Samsung focusses down to 5 cm.
• Sony can focus as close as 1 cm, coupled with optical image stabilization.

Sony’s better close-focusing and stabilization make it a stronger choice for macro work or capturing fine details without a tripod.

Night and Astro Photography

Both cameras lack manual exposure modes or RAW support, limiting astro and nighttime potential.

• Sony allows max ISO 3200, better for low light shooting.
• Samsung maxes at 1600 and exhibits more noise.
• Neither features long-exposure control beyond 8s shutter speed on Samsung and 4s on Sony.

Sony’s high ISO benefit and improved stabilization offer a slight edge for handheld nighttime shots.

Video Capabilities: Basic vs Full HD

Video is an important secondary feature, especially on compact cameras:

Sony’s ability to record Full HD video at 60 fps with OIS makes a substantial difference in quality and usability. Samsung’s VGA video capture is now far too low for any serious video purposes.

Build Quality, Durability, and Battery Life

Judging build quality and endurance:

• Samsung offers no weather sealing or environmental protections.
• Sony includes environmental sealing - a rare feature at this price point - offering minor reassurance against dust and light moisture.
• Battery life favors Sony, rated around 250 shots per charge vs. vague Samsung claims (likely lower).

Weight benefits Sony again here, at 133g vs. 168g Samsung - with obvious portability gains for travel.

Connectivity and Storage Options

Sony’s Eye-Fi compatibility allows wireless image transfers - a modern convenience lacking in Samsung’s offering.

Price-to-Performance Ratio: Which Camera Offers Better Value?

• The Samsung SL720 is found new or refurbished around $120.
• The Sony TX20 generally retails for about $330.

The Samsung is an attractive budget option for absolute casual users prioritizing ultra-portability over image quality or features. However, for a ~$200 premium, the Sony offers huge gains in image quality, autofocus, video capabilities, and overall usability.
