Olympus TG-870 vs Samsung ST700: A Deep Dive into Ultracompact Photography Tools

Choosing the right ultracompact camera can be deceptively complex, especially when models come from varied eras with vastly different feature sets and design philosophies. Today, I’m bringing you a hands-on, comprehensive comparison between two such cameras: the Olympus Stylus Tough TG-870 (2016) and the Samsung ST700 (2011). Both are targeted at users wanting portable solutions without the bulk of larger cameras, yet their approaches diverge sharply.

I’ve spent well over a hundred hours shooting, testing, and analyzing these cameras under various conditions across portrait, landscape, wildlife, and travel photography to give you the clearest understanding of what each offers. Let’s unpack their specs, hands-on experience, and ultimately how they stand in the modern photography landscape.

First Impression: Size and Handling in Your Hands

When it comes to ultra-portable cameras, size and ergonomics immediately shape usability. The Olympus TG-870, despite its “tough” rugged ethos, remains compact but measurably larger and more robust than the Samsung ST700.

The TG-870 measures 113 x 64 x 28 mm and weighs a solid 221 grams, with grips and a sturdy exterior that inspire confidence if you’re hauling it on treks or beach trips. Its ergonomics reflect Olympus’s long experience in designing tough, easily handled compacts. The textured grip zones, well-placed buttons, and a decent heft that balances stability without fatigue make it a joy to hold.

On the flip side, the Samsung ST700 is significantly smaller and slimmer - just 99 x 55 x 20 mm - with a lightweight design. It’s pocket-friendly to the point that it disappears in your hand, but this comes at a tactile cost: the ST700 feels plasticky and borderline flimsy. In practical terms, I found the TG-870 easier to manage during extended handheld shooting sessions, especially in challenging conditions or when you want to steady the camera for macro or low light shots.

Design and Control Layout: User Interface Matters

Physical size only tells part of the story; control layout and interface responsiveness are central to a satisfying shooting experience.

The TG-870’s top view reveals an intentional control cluster: a shutter button front-and-center plied with zoom toggle; a dedicated movie record button, and a power switch all comfortably within thumb and forefinger reach. The absence of an electronic viewfinder is mitigated somewhat by the tilting LCD screen, which unlocks more creative shooting angles.

Contrast this with Samsung ST700’s restrained controls - optimized for simplicity but at the cost of versatility. The buttons are smaller, less tactile, and the camera lacks customizable dials or quick access to exposure settings. That touchscreen is convenient for menu navigation, but for shooting, having no physical shortcuts limits quick responsiveness, especially for action or macro shots.

Sensor and Image Quality: The Heart of the Matter

Sensor technology is the foundational pillar of image quality. Olympus equips the TG-870 with a 1/2.3” BSI-CMOS sensor offering 16 MP, whereas the Samsung relies on an older 1/2.3” CCD sensor with the same nominal resolution.

The difference between BSI-CMOS and CCD comes alive in practical use. BSI (backside illuminated) CMOS sensors, like in the TG-870, capture light more efficiently, reducing noise and improving dynamic range, especially at mid-to-high ISOs. In contrast, CCDs, which dominated compact cameras of the early 2010s, usually struggle in low light and have slower readout speeds.

In my lab tests, the TG-870 delivered notably cleaner images beyond ISO 800, while the ST700’s noise became intrusive past ISO 400 - something to keep in mind if you shoot in dim environments or indoors. Both cameras share the same sensor size, which caps their ultimate diffraction-limited resolution, but Olympus’s more modern processor (TruePic VII) optimizes color rendering and sharpness better.

Color accuracy and skin tone reproduction are critical for portrait shooters. The TG-870 produced lifelike, warm skin tones with subtle preservation of texture, even under mixed lighting. Samsung’s rendition skewed slightly toward cooler hues and less natural texture, making post-processing necessary to tame highlights.

Live View and LCD Screen Experience

Shooting without an electronic viewfinder demands a great LCD, so I paid extra attention to how both cameras perform here.

The TG-870 features a 3-inch tilting screen with 921k-dot resolution - bright, sharp, and versatile. Tilting the screen makes framing creative low- or high-angle shots intuitive, indispensable for macro or street photography where unusual perspectives add interest.

Conversely, the ST700’s screen is fixed, only 230k dots, and uses a touchscreen interface. While touchscreen navigation excels for quick menu browsing or image review, the lower resolution hampers confidence in critical focus checking. The fixed position frustrates framing flexibility, especially when trying unconventional angles.

Overall, the TG-870’s display offers a more professional-grade experience supporting accurate composition and critical evaluation in both bright sunlight and shadowed conditions.

Autofocus: Speed, Accuracy, and Tracking

Here’s a deal breaker for anyone shooting moving subjects: autofocus speed and reliability. The TG-870’s hybrid autofocus system relies on contrast detection with continuous autofocus and face detection. The ST700, meanwhile, lacks continuous or face detection autofocus and is limited to single AF with no tracking functionality.

In wildlife or sports shooting tests, the TG-870 shows acceptable tracking, locking onto centrally framed faces or subjects swiftly with reasonable accuracy. Continuous AF keeps pace during slow subjects’ movement but unsurprisingly struggles with high-speed action, typical for cameras in this class.

The ST700’s AF system often hunts in low-light or complex scenes, lacking the sophistication to maintain focus without manual intervention. Face detection is absent, making portraits a guessing game if your subject moves.

For shooting pets, kids, or casual sports, Olympus’s approach is markedly superior - not at the level of interchangeable-lens mirrorless systems, but respectable given the compact form factor.

Lens Capabilities and Macro Performance

Optical versatility can distinguish ultracompacts. The Olympus TG-870 sports a 21-105mm equivalent f/3.5-5.7 lens, with a 5x zoom range and a fantastic minimum focusing distance of 1 cm for macro work. Samsung’s ST700 lens specs are less clear, but it has the same focal length multiplier of 5.8x with limited aperture information and no true macro specification.

Macro photography is an area where TG-870 shines. Hands-on, I was able to capture sharp, close-focus detailed images of flowers, insects, and textures that the ST700 struggled to match. The optical image stabilization in the Olympus (absent in the Samsung) also lets you shoot handheld at close range with less blur - a big practical advantage.

In simple terms: If you value shooting tiny details, textures, or want to experiment with macro in an ultracompact, the Olympus’s lens is a clear winner.

Burst Rate and Shutter Specifications

For action and wildlife photographers, frame rate and shutter speed range are vital metrics. The TG-870 boasts a maximum continuous shooting rate of 7fps, which is solid among compacts, while Samsung does not provide burst rate info, likely due to its more limited processing speed.

Shutter speeds on both cameras top out at 1/2000 second, adequate for daylight and general use but not suited for freezing ultra-fast motion or ultra-wide aperture shooting.

The TG-870 also supports shutter speeds as slow as 4 seconds, enabling some creative long exposures, whereas Samsung’s minimum shutter speed is listed at 8 seconds with no additional manual exposure controls. Neither camera offers shutter or aperture priority modes.

Weather Sealing and Durability: Built for Adventure?

One of Olympus’s marquee selling points is environmental sealing. The TG-870 is waterproof (up to 15m), shockproof (2m drop), freezeproof (-10°C), and crushproof to 100kgf. This ruggedness elevates it from a simple compact to a true adventure camera. It’s the kind of device you can confidently take on hikes, snorkelling trips, or mountain biking.

Samsung ST700 has none of these protections. It’s designed purely for casual indoor or outdoor day use, without rugged ambitions.

For outdoor enthusiasts or anyone prone to rough handling, Olympus offers a critical edge with peace of mind.

Video Features: Full HD vs HD

Videographers often look to ultracompacts for casual video shooting, so let’s cover that.

The TG-870 records Full HD 1080p at 60fps, encoding in MPEG-4/H.264 - very good for a camera in this class. It also has a built-in LED illuminator but lacks external mic input or headphone jacks, limiting serious video production use.

Samsung ST700 records only 720p HD video at 30fps, an older baseline that may look dated on modern displays.

Neither camera provides 4K or “photo modes” like 4K burst photo capture. Video stabilization is optical on Olympus, absent on Samsung.

For casual videographers or travel vloggers, the TG-870’s higher resolution video, better stabilization, and frame rates provide a smoother, more professional feel.

Battery Life and Storage

Real-world shooting sessions demand robust battery life and flexible storage.

The Olympus TG-870 offers approximately 300 shots per charge using its proprietary Li-50B battery, which I verified in mixed shooting scenarios - enough for a day’s worth of outdoor work with some video mixed.

Samsung ST700’s battery life is unspecified, and it uses a non-proprietary but generally lower-capacity battery prone to faster drain. Charging convenience and spare availability may also be a consideration given its age.

Both cameras accept SD/SDHC/SDXC cards, but Olympus’s support for SDXC ensures future-proofing with higher-capacity cards.

Connectivity and Extras

Modern cameras increasingly rely on wireless connectivity as part of their appeal.

The TG-870 comes with built-in Wi-Fi and GPS, allowing geotagging your images on the fly and easy image transfer or remote control via smartphone apps. This integration streamlines workflows and travel shooting.

Samsung’s ST700 has no wireless connectivity features, no GPS, no USB port, and lacks HDMI output. In contrast, Olympus provides USB 2.0 and HDMI out, useful for instant on-camera image review or media offload.

Connectivity packages like these may sway travel and casual shooters who like smart features.

Comparing Sample Images: Real-World Results

I carried both cameras on urban strolls and wilderness hikes to compare output directly.

In daylight portraits, Olympus’s face detection and color science rendered skin tones warm and natural; Samsung’s cooler cast felt less flattering. Depth of field is shallow with Olympus’s longer-focal-length lens end, producing gently blurred backgrounds (good bokeh) that the Samsung can’t match due to lens and focus limitations.

Landscape shots revealed Olympus’s superior dynamic range - retaining highlight and shadow detail even under bright sun and shade dapple. Samsung images tended to clip highlights and lose shadow nuance.

In lower light, Olympus’s superior sensor and stabilization captured usable images with less noise and more detail. Samsung’s images frequently became soft and grainy at higher ISOs.

Performance Ratings at a Glance

Olympus TG-870 clearly outperforms Samsung ST700 across most areas: build quality, autofocus, image quality, video, and ruggedness. Samsung scores are hampered by aged sensor tech, lack of stabilization, and basic ergonomics.
