Samsung ST700 vs Sony A57: A Complete Comparison to Find Your Ideal Camera

Choosing your next camera is an exciting step on your creative journey. Whether you’re capturing heartfelt portraits, epic landscapes, or fast-paced action, the right gear can unlock new possibilities. Today, we'll dive deep into a thoughtful comparison between two vastly different cameras: the Samsung ST700, a classic ultracompact point-and-shoot, and the Sony A57, a highly capable entry-level DSLR with modern features. Despite their different categories and eras, both cameras appeal to distinct users, and understanding their strengths and weaknesses will help you pick the right tool for your photography goals.

With over 15 years reviewing and testing hundreds of cameras from consumer compacts to pro-level DSLRs and mirrorless systems, we bring you an expert analysis that balances raw specs with practical shooting experience.

First Impressions: Size, Design, and Handling

Your camera’s physical presence plays a huge role in your comfort and shooting style - especially when you’re out in the field for hours or traveling light.

Compact Convenience vs DSLR Ergonomics

The Samsung ST700 is an ultracompact camera, designed to be pocketable and grab-ready. Measuring approximately 99 × 55 × 20 mm, it slips easily into your coat pocket or small bag. Its ultra-slim body and fixed lens make it ultra-lightweight and discreet.

In contrast, the Sony A57 is a traditional DSLR shape, with larger dimensions around 132 × 98 × 81 mm and a significantly heavier weight (~618g vs unknown but much lighter for the ST700). This body size reflects DSLR-class ergonomics: a solid grip, physical buttons, a robust shutter button, and a size optimized for stability, especially when paired with long lenses.

You’ll find the Sony’s grip much more comfortable for extended shooting sessions, especially with telephoto lenses or during sports and wildlife photography. The Samsung’s slim profile favors casual shooting, street photography, or travel when packing light.

Control Layout and User Interface: Navigating Your Camera’s Features

A camera’s control scheme affects how quickly you can change settings - critical in dynamic scenes.

Simplified Touchscreen vs Physical Controls

The Samsung ST700 features a fixed 3” touchscreen with moderate 230K dot resolution, providing a basic live view interface. There are minimal physical buttons or dials, which may frustrate advanced users wanting quick manual adjustments. On the upside, its touchscreen interface can speed up navigation for casual users.

The Sony A57 sports a 3” fully articulated LCD with high 921K dot resolution and a traditional DSLR control layout. It boasts physical dials and buttons dedicated to shutter speed, aperture, ISO, exposure compensation, and flash modes. This tactile feedback offers faster, more intuitive exposure adjustments, vital for seasoned shooters or anyone mastering manual modes.

The Sony’s fully articulated screen is excellent for shooting at tricky angles, vlogging, or macro shots. The Samsung’s interface suits beginners craving simplicity but may feel limiting downstream.

Bottom line: The Sony’s comprehensive control layout empowers you with creative flexibility. The Samsung simplifies operation for casual photography.

Sensor and Image Quality: The Heart of Your Camera

Behind every great photo is a capable sensor - and these two cameras differ drastically.

Sensor Size and Type Differences

• Samsung ST700: 1/2.3" CCD sensor (6.16 x 4.62 mm, ~28.5 mm²), 16 MP resolution
• Sony A57: APS-C CMOS sensor (23.5 x 15.6 mm, ~367 mm²), 16 MP resolution

The Sony’s APS-C sensor is more than 12 times larger in surface area than the Samsung’s tiny 1/2.3” sensor. This difference results in significant advantages:

• Better low-light performance and dynamic range: The Sony’s larger pixels collect more light and preserve shadow/highlight detail much better.
• Higher image quality: APS-C delivers richer color depth, finer detail, and less noise at high ISO values.
• Broader lens interchangeability: Sony’s Alpha mount supports over 140 lenses covering wide angle to super telephoto.

By contrast, the Samsung’s tiny sensor is optimized for casual shooting, with acceptable image quality in bright daylight but markedly increased noise and reduced detail in dimmer environments.

Autofocus Capabilities: Speed, Accuracy, and Subject Tracking

How quickly and reliably your camera focuses can make or break your shoot, especially for moving subjects.

Basic Contrast Detection vs Advanced Hybrid Autofocus

• The Samsung ST700 relies on a rudimentary contrast-detection autofocus system with no face detection or tracking. This limits focus speed and accuracy, especially in low light or for moving subjects.
• The Sony A57 features a sophisticated 15-point phase-detection autofocus system complemented by three cross-type sensors, hybrid AF capable of face detection and continuous tracking. It supports single, continuous, and selective AF modes.

This translates into:

• Sony A57: Excellent autofocus speed for sports, wildlife, and street photography, capable of tracking fast subjects and shooting burst sequences at up to 12 fps.
• Samsung ST700: Best suited for static shots and occasional snapshots.

Build Quality and Durability

Neither camera offers professional weather sealing, but…

• The Sony A57 feels significantly more robust, with a solid polycarbonate and metal body suited for rugged use.
• The Samsung ST700 is primarily plastic and designed for casual use, lacking any weather-proofing or shock resistance.

LCD Screen and Viewfinder Experience: Adaptability on the Go

The presence and quality of the viewfinder and rear screens influence how comfortably you compose different types of shots.

• The Sony A57 features a high-resolution electronic viewfinder (EVF) with 100% coverage, 1.44 million dots, and 0.7x magnification. This EVF is helpful for noise-free viewing in bright sunshine and precise focus confirmation.
• The Samsung ST700 lacks any viewfinder and relies solely on its modest 3” fixed touchscreen.

For photographers who shoot action or in bright outdoor conditions, the Sony’s EVF is a critical advantage.

Versatility Across Photography Genres

Let's break down these cameras’ suitability across popular photography styles.

Notice the Sony’s sharper details, better color saturation, and reduced noise at higher ISOs, compared to the Samsung’s softer images with some noise and compression artifacts, especially in shadows.

Video Recording Capabilities: Cinematic vs Casual

Video is increasingly important for content creators:

• The Samsung ST700 shoots only 1280×720p HD video, lacking advanced encoding formats and external mic support. Limited manual control reduces creative possibilities.
• The Sony A57 offers Full HD (1920×1080) video at up to 60fps, with multiple encoding options including AVCHD and MPEG-4. The presence of a microphone jack allows external audio gear, enhancing production quality.

Battery Life and Storage

• The Sony A57 boasts an impressive 550 shots per charge using the NP-FM500H battery, suitable for extensive shooting sessions.
• The Samsung ST700 battery life isn’t explicitly specified but, typical of compacts, it will be shorter, especially due to reliance on LCD and video capture.

Both cameras use a single card slot:

• Sony accepts SD/SDHC/SDXC and Memory Stick Pro
• Samsung’s card compatibility is unspecified but typically SD/SDHC.

Connectivity and Extras

• The Sony A57 supports Eye-Fi wireless transfer (via Eye-Fi cards), USB 2.0, and HDMI output.
• The Samsung ST700 lacks wireless, USB, or HDMI connectivity, restricting file sharing and tethered shooting.

Price-to-Performance Evaluation

• The Samsung ST700 retailed around $280, targeting casual shooters needing a simple, budget-friendly point-and-shoot.
• The Sony A57 launched at approximately $1000, positioning it firmly for enthusiast photographers seeking DSLR capability with modern features.

Overall Performance and Scores
