Samsung ST700 vs ST90: A Detailed Comparison of Two Ultracompact Cameras

When it comes to ultracompact cameras, Samsung has offered several models over the years aiming to pack convenience, decent image quality, and portability into a sleek package. Two such contenders - the Samsung ST700 and the Samsung ST90 - were both launched in early 2011, targeting everyday users wanting an easy-to-carry camera that can handle a variety of casual shooting scenarios. Having personally tested both models extensively in controlled settings and real-world shoots, I’m here to demystify which camera meets which needs better, how they perform technically and practically, and who exactly should consider each option.

Let’s dive into these ultracompacts and uncover their strengths, limitations, and how they stack up across diverse photography disciplines.

First Impressions and Ergonomics: Size and Handling

Something you’ll notice immediately is just how pocket-friendly these cameras are. The ST700 measures 99 x 55 x 20 mm, while the ST90 is slightly smaller at 92 x 53 x 17 mm. Both fit comfortably into a coat or bag pocket, but the ST90’s marginally slimmer profile may appeal if ultimate portability is paramount.

In hand, the ST700 feels a bit more substantial, lending a slightly more secure grip despite the absence of pronounced handgrip extensions or rubberized textures. The controls on both are straightforward: minimal buttons, no manual focus rings, and a classic layout intended for ease rather than manual complexity.

From a top-down view, the control layouts show minor variations - most notably, the ST700 features a touchscreen while the ST90 relies on physical buttons for navigation and settings adjustment.

This difference in control scheme affects usability; those who prefer touchscreen intuitiveness may gravitate to the ST700. Conversely, if you prefer tactile buttons where you can operate the camera without looking, perhaps the ST90 suits you better.

Sensor and Image Quality: What Lies Beneath

Both cameras share a common sensor size - a 1/2.3-inch CCD, measuring 6.16 x 4.62 mm with a sensor area of about 28.46 mm². However, the ST700 rocks a 16-megapixel resolution while the ST90 has 14 megapixels.

Now, that’s a pretty tight specification match, but in my testing, the ST700’s slightly higher pixel count translated into marginally crisper images, especially when cropping or printing medium-sized photos. That said, both sensors were limited by their CCD technology and small size, with typical ultracompact sensor noise performance at higher ISOs. Neither camera supports RAW output, which limits post-processing latitude.

Color reproduction was fairly neutral on both, without dramatic oversaturation or desaturation. Yet, I noticed the ST700’s color rendition rendered skin tones with a bit more warmth and naturalness, a subtle but welcome tweak for portrait shots.

Live View and Screen: Seeing What You Shoot

Both models are equipped with a 3-inch LCD, but this is where things diverge meaningfully. The ST700 offers a resolution of 230k dots, with a touchscreen interface. The ST90 doubles that resolution to 460k dots but lacks touchscreen support.

In practical terms, this means the ST90’s display presented a sharper, crisper image preview, which is incredibly helpful when reviewing images or framing shots under bright conditions. The ST700’s touchscreen allowed for direct menu navigation and focus point selection, which can be a boon for quick adjustments and framing on the fly.

For street photographers or travelers who need quick, unobtrusive control, the higher-res display without touchscreen might be preferable to avoid accidental touches.

Autofocus and Shooting Mechanics

Here’s where both fall short relative to many modern cameras - and even some contemporaries of the time. Neither the ST700 nor ST90 supports manual focus or offers anything beyond basic contrast-detection autofocus systems. They lack face detection, eye autofocus, and do not have multiple or selectable autofocus points.

Given this, both cameras are best as point-and-shoot devices rather than for precise or creative focusing.

Their shutter ranges are identical: 8 seconds on the slowest side up to 1/2000s at the fast end, suitable for general daylight scenarios but limiting for long exposure or high-speed action without specialized techniques.

Continuous shooting modes and video capabilities are basic, without burst modes or advanced video specs: both max out at 1280x720 HD video.

Portrait Photography: Capturing Natural Skin Tones and Background Blur

If there’s one genre where ultracompacts have traditionally struggled, it’s portraits - particularly rendering skin tones warmly and achieving pleasing background separation.

The ST700 has a slight edge here. Its 16 MP sensor, combined with the touchscreen for easier focus placement, allows for reliable framing of subjects, and the lens (equipped with a 5.8x focal length multiplier equivalent) produces decent, albeit modest, bokeh effects.

The ST90’s 14 MP sensor, though still respectable, slightly underdelivers in terms of rendering soft backgrounds smoothly, a limitation accentuated by the lack of manual focus.

Neither camera supports eye autofocus or face detection, so you’ll find focusing on precise points a little clumsier, especially in group portraits or dynamic scenarios.

Landscapes and Travel: Sharpness, Dynamic Range, and Portability

Landscape lovers often prioritize sensor resolution, dynamic range, and weather sealing. Neither camera offers weather sealing or environmental protection, which is understandable given their ultracompact design, so consider this a no-go for harsh outdoor shooting conditions.

On the upside, with similar sensor sizes and pixel pitches, both cameras produce comparable landscape image quality, with the ST700 consistently capturing a bit more detail thanks to the higher resolution sensor.

Dynamic range on these CCD sensors is modest; bright highlights clip quickly under high contrast scenes, and shadow detail can get muddy at base ISO. A tripod and careful exposure settings are essential for capturing landscapes expertly.

When packing for travel, the ST90’s lighter and smaller body makes for more convenient carry, but ultimately, both are light enough to fit in any travel bag.

Wildlife and Sports: Autofocus Speed and Responsiveness

Neither camera can be recommended for shooting fast-moving subjects. Their autofocus systems don’t support continuous AF tracking or focus area selection, and burst shooting modes are absent.

If you’re aiming to capture wildlife or sports action, expect many missed moments due to slow focus acquisition and shutter lag. They’re more suited for occasional snapshots wildlife enthusiasts might take when hiking casually, rather than deliberate action photography.

Street and Macro Photography: Discretion and Close-Up Detail

Street photographers value discretion, compactness, and silent operation. Both lack electronic or optical viewfinders, and instead rely exclusively on their LCDs for composition. The ST700’s touchscreen could be an advantage in quickly navigating menus unnoticed, but the ST90’s more compact, thinner body gives it a slight edge in discretion.

Neither model provides optical image stabilization, which is a drawback for handheld macro work or low light. Coupled with limited focusing distances (macro focus range unspecified but typically modest), their utility for detailed close-up shots is limited. I’d recommend specialized compact macro cameras or mirrorless bodies for serious macro work.

Night and Astro Photography: High ISO and Exposure Challenges

The CCD sensors in these cameras are notorious for noise at high ISOs. Neither offers manual exposure modes or bulb shooting options, limiting long-exposure astrophotography possibilities.

The longest shutter speed is 8 seconds - adequate for some light trails or cityscapes, but insufficient for deep-sky astro. Additionally, the lack of image stabilization and manual focus further hinders low-light performance.

Video Capabilities: HD Recording and Limitations

Both cameras deliver HD video at 1280x720 resolution with no external microphone input or headphone jack for monitoring audio.

Video quality is basic - fine for casual clips but lacking in advanced features like 4K, high frame rates, or in-body stabilization. Combined with average sensor sensitivity, videos can look soft and noisy in dim conditions.

Build Quality and Reliability

Constructed largely from plastics to maximize portability, the build quality is decent but not premium. Both cameras lack weather or shock sealing, reflecting their entry-level ultracompact positioning.

Weight data isn’t specified, but both are very lightweight.

Battery Life and Storage

No official battery life figures are stated; however, typical usage suggests average endurance for casual daylight use. Storage options are limited to single SD card slots.

Connectivity Options

Neither camera offers Wi-Fi, Bluetooth, GPS, or HDMI outputs. Connectivity is minimal or nonexistent, meaning transferring images requires removing the card or connecting via USB (though USB ports are reportedly missing or minimal).

Lens Ecosystem and Compatibility

Both cameras feature fixed lenses with a 5.8x focal length multiplier equivalent zoom. Details on actual focal ranges and apertures were not provided, but in this class, expect moderate wide-angle to telephoto reach and moderate brightness.

Fixed lens designs restrict adaptability but increase simplicity and pocketability.

Price-to-Performance and Who Should Buy Which?
