Olympus TG-870 vs Samsung ST93: An Exhaustive Comparison for the Ultracompact Camera Enthusiast

Selecting the right ultracompact camera can be a nuanced decision, often balancing portability, image quality, and feature set against budget constraints. In this detailed comparison, I draw on over 15 years of extensive camera testing experience to dissect two notable but disparate models in this class: the 2016 Olympus Stylus Tough TG-870 and the 2011 Samsung ST93. Despite sharing a compact category classification, these cameras diverge significantly in technology, capability, and intended usage scenarios. This juxtaposition will help photographers - from casual shooters to discerning enthusiasts - understand which device better fits their photographic ambitions, offering a clear-eyed, data-driven perspective anchored in hands-on experience.

Getting Acquainted: Basic Physical and Design Contrasts

The fundamental appeal of ultracompact cameras often lies in small form factor and ease of carry. The Olympus TG-870, known for its robust build tailored to adventurous photographers, commands a larger but rugged presence with physical dimensions of 113x64x28 mm and a weight of 221 g. In contrast, the Samsung ST93 emphasizes minimalist portability, boasting a notably smaller chassis of 92x53x17 mm and lighter heft at just 110 g.

From a size and ergonomics standpoint, the TG-870’s larger grip and durability-oriented design is conducive to more confident handheld shooting, especially in challenging outdoor environments, whereas the ST93’s svelte profile favors inconspicuous street shooting or casual snapshots. My real-world tests confirm that while the ST93 excels in pocketability, the TG-870’s ergonomic contours and button layout yield superior operational stability during extended sessions and active shooting.

Control Layout and Interface: Navigating the Cameras

On moving beyond size into user interaction, the distinction between control philosophies becomes even clearer. The Olympus TG-870 features a top panel dense with tactile buttons and dials, catering to users who prefer manual adjustments and quick access to settings. This attention to control design reflects Olympus’s heritage in sport and outdoor cameras.

Conversely, the Samsung ST93 has a minimalist interface, embracing fixed-function simplicity with fewer buttons and no dedicated dials - essentially favoring auto-mode use and beginner-friendliness at the cost of creative control.

This divergence is palpable during testing: the TG-870’s control scheme supports rapid exposure tweaks and toggling of modes (important for travel or wildlife photography), while the ST93’s rigidity limits responsiveness. Users accustomed to adjusting parameters on the fly may find the ST93’s UI frustratingly sparse.

Sensor Technology: The Heart of Image Quality

Analyzing sensor architecture is critical because it fundamentally determines image fidelity, dynamic range, and noise performance. Both cameras utilize a 1/2.3-inch sensor dimension; however, sensor technology and processing diverge sharply.

The Olympus TG-870 employs a backside-illuminated (BSI) CMOS sensor with 16MP resolution, coupled with the TruePic VII processor. This pairing enhances light gathering efficiency - improving low light behavior - and translates into more vibrant color reproduction and improved dynamic range. The sensor area of approximately 28.07 mm² and the presence of an anti-aliasing filter maintain a balance between resolution and aliasing artifacts.

Conversely, the Samsung ST93 relies on a CCD sensor, also at 16MP but without BSI benefits, coupled with aging image processing technology. Its sensor area, comparable at 28.46 mm², does not compensate for CCD’s intrinsic limitations such as slower readout speeds, increased noise at higher ISO, and reduced dynamic range.

Empirically, the TG-870 regularly delivers cleaner images at ISO 800 and above, with less color noise and better shadow detail retention, whereas the ST93’s CCD sensor introduces generically higher noise levels starting at ISO 400, restricting its usable sensitivity range and impacting night and event shooting.

Screens and Viewfinders: Composing Your Shot

Both cameras eschew optical or electronic viewfinders, a common trait in ultracompacts aimed at casual or adventure users. They rely solely on rear LCD screens for framing and menu navigation.

The Olympus TG-870 sports a 3-inch tilting LCD with 921k-dot resolution, offering excellent brightness and flexible composition angles (critical for shooting at low or overhead perspectives) - a boon for macro, landscape, or street photography where varied vantage points enhance creativity.

The Samsung ST93 offers a fixed 3-inch screen at 460k dots, exhibiting lower resolution and no tilt functionality, limiting compositional versatility and making it harder to monitor fine detail outdoors in bright light.

During outdoor tests, the TG-870’s screen consistently proved superior for previewing focus and image detail, especially under bright sunlight - a scenario where the ST93’s fixed, lower-res screen struggled, increasing the necessity of trial-and-error shooting.
