Samsung ST700 vs Sony A7S III: An Expert’s In-Depth Comparison for 2024
Every photographer has unique needs, whether chasing the perfect portrait, capturing sweeping landscapes, or filming high-quality video. Over my 15+ years testing cameras, I’ve often contrasted entry-level compacts against professional mirrorless bodies - not simply to compare specs on paper but to understand how real-world use impacts image quality, versatility, and overall satisfaction.
Today, I’m laying bare such a contrast: the 2011 Samsung ST700 ultracompact versus the flagship Sony A7S III mirrorless from 2020. This is a testament to technological leaps, and an opportunity to unpack what each camera can - and cannot - offer in 2024. Spoiler: the gap reflects both technological evolution and divergent photographic ambitions.
Let’s dive deep into their design, image quality, versatility, and suitability across multiple photography disciplines.
Seeing Them Side-By-Side: Size and Ergonomics
Starting with the physical form, the Samsung ST700 is a petite ultracompact at 99x55x20 mm, designed to slip unobtrusively into a pocket or small bag. In contrast, the Sony A7S III is a full-featured SLR-style mirrorless camera at 129x97x81 mm - significantly larger and heftier. The Sony’s size stems from its robust build, larger sensor, comprehensive controls, and weather sealing.
Holding both reveals vastly different shooting experiences. The ST700 feels almost toy-like but benefits from extreme portability. However, its small size means cramped controls and a lack of physical dials, affecting intuitive use for serious photography.
The A7S III immediately projects professionalism: deep grips, button layouts tailored for photographers and videographers alike, and weather-sealed durability ideal for intense outdoor work. For users accustomed to minimalist design, this camera demands more space but rewards control precision and handling comfort.
Design and Control Layout: Navigating the Interface
Beyond size, control ergonomics dictate how a camera feels during shooting sessions.
The Samsung ST700 sports a simple top plate with minimal buttons, no analog dials, and a basic flash toggle. The touchscreen LCD is the primary interface - touch-enabled but limited by lack of manual exposure controls.
In contrast, the A7S III incorporates an advanced top plate replete with multi-function dials, customizable buttons, a dedicated exposure compensation dial, and a silent shutter switch. This layout is designed for fast adjustments on the fly - critical for dynamic shooting such as events or wildlife.
Sony’s touchscreen supports focus point selection and menu navigation, complimenting a high-resolution electronic viewfinder (EVF). The ST700 lacks an EVF entirely, restricting composition to the LCD - a disadvantage under bright sunlight or fast-action situations.
For serious photographers, the A7S III’s thoughtfully constructed interface accelerates workflow and improves responsiveness during shoots.
Inside Matters: Sensor Size, Resolution, and Image Quality
The heart of image quality is the sensor, and here the two cameras couldn’t be more different.
Samsung ST700: Equipped with a small 1/2.3" CCD sensor measuring 6.16x4.62 mm, with 16 megapixels, this compact sensor is standard in point-and-shoots of its era but limited by noise handling and dynamic range capabilities. The CCD sensor, while historically popular, is less sensitive in low light compared to modern CMOS technologies.
Sony A7S III: Boasting a full-frame back-illuminated CMOS sensor of 35.6x23.8 mm, the A7S III sports 12 megapixels optimized for extraordinary low-light sensitivity with a native ISO range extending from 80 all the way to 102,400 and boostable to 409,600. Its sensor area, nearly 30 times larger than the ST700’s, affords remarkable noise performance, wider dynamic range, and natural background blur at wide apertures.
This sensor difference translates directly into image quality gaps:
-
Dynamic Range: The A7S III delivers roughly 13.3 stops of dynamic range, enabling recovery of highlights and shadows flawlessly - critical for landscapes and high-contrast scenes. The ST700, by comparison, falls short, demanding careful exposure.
-
Color Depth: Sony’s 23.6-bit color depth ensures fine gradations and color fidelity, superior to the limited performance of the Samsung’s CCD.
-
Noise Handling: The A7S III remains remarkably clean at high ISOs, while the ST700’s image quality rapidly degrades in challenging light.
To photographers prioritizing image excellence, the A7S III’s sensor is a game-changer; the ST700’s sensor suits casual snapshots and bright daylight conditions.
Viewing and Composing: LCD and Viewfinders Compared
Good composition tools can make or break a shoot, especially under demanding conditions.
The Samsung ST700 offers a modest fixed 3-inch screen at 230k dots resolution, functional but prone to glare and limited detail. There is no option for an EVF or tilting/swiveling screen, restricting flexibility in unusual shooting angles.
On the other hand, the Sony A7S III features a fully articulating 3-inch LCD with an impressive 1.44 million dots - sharp, bright, and highly responsive to touch. Complementing this is an electronic viewfinder boasting a super-high resolution 9.44 million dots (or "9440" per specifications), vital for critical focusing and precise framing, especially in bright sun or low light.
The A7S III’s user interface supports extensive customization, quick menu access, plus sophisticated focus and exposure overlays for advanced photographers.
If you regularly shoot outdoors or crave flexible camera angles and precise framing, the A7S III clearly dominates.
Portrait Photography: Skin Tones, Bokeh, and Eye Detection
Portrait work demands subtle image quality nuances - accurate skin tones, creamy bokeh, plus fast and reliable autofocus to nail expressive eye contact.
-
Samsung ST700: The small sensor and fixed lens limit background separation. It has no face or eye detection autofocus, making sharp portraits harder, especially if your subject moves. Skin tones can be decent in good light but appear flat or over-smoothened due to internal processing.
-
Sony A7S III: Featuring advanced real-time Eye AF (including animal eye detection), 759 focus points, and phase-detection autofocus, the A7S III tracks eyes with surgical precision even in motion or low light. Depth of field control is superb with compatible fast prime lenses, delivering beautifully rendered bokeh to isolate subjects.
In my portrait sessions, the A7S III’s autofocus keeps pace with spontaneous expressions, while the ST700 struggles in dynamic settings.
Landscape Photography: Dynamic Range and Weather Sealing
Landscape photographers prize high resolution, extensive dynamic range, and durable construction.
-
The ST700’s smaller sensor limits detail and tonal depth, though it can produce sharp images on bright, flat-light days. Its plastic body offers no weatherproofing, so shooting in adverse environments is risky.
-
The Sony’s robust magnesium alloy chassis boasts weather sealing against dust and moisture - a boon when trekking to remote locations. The 12MP full-frame sensor may seem modest resolution but excels in delivering rich texture, shadow recovery, and highlight preservation.
As a long-time landscape shooter, I appreciate the Sony’s versatility and reliability; the Samsung cedes too much ground here.
Wildlife Photography: Autofocus and Burst Capture
Capturing fast-moving wildlife demands precise AF and good burst rates.
-
The ST700 lacks continuous autofocus and burst shooting capabilities. Its fixed lens and slow shutter top out at 1/2000s, insufficient for fast action. Without tracking AF or face/eye detection, many shots will be missed.
-
The Sony A7S III shines with 10fps continuous shooting, real-time subject tracking AF, 759 points, and compatibility with a wide telephoto lens ecosystem. Its shutter speeds extend to 1/8000s, perfect for freezing motion in bright light.
