Olympus TG-850 iHS vs Sony TX55: A Thorough Dive into Two Compact Powerhouses

Choosing a compact camera can feel tricky given the diversity on offer - between rugged waterproof models and sleek, ultra-portables designed for everyday carry, each targets a specific user need. Holding both the Olympus Stylus Tough TG-850 iHS and the Sony Cyber-shot DSC-TX55 side-by-side recently, I set out to analyze what truly sets these two apart.

Both cameras promise solid image quality from their 16-megapixel 1/2.3” BSI-CMOS sensors, but their built-in features, ergonomics, and real-world performance cater to very different shooting philosophies. Here’s my detailed comparison, grounded in hands-on experience, technical knowledge, and assessing which enthusiast or professional might benefit most from either option.

First Impressions: Size Matters - And So Does Handling

Before firing up either camera, I always start with the physical presence and user interface. After all, how a camera feels in your hand profoundly influences shooting comfort and frequency.

The Olympus TG-850 iHS is decidedly rugged, built to survive tough outdoor adventures - it’s waterproof (up to 10 meters), dustproof, shockproof, crushproof, and even freezeproof. The trade-off? A chunkier, heavier body measuring 110x64x28 mm and weighing 218g. Its larger size and pronounced grip make it easy to hold securely even with gloves or wet hands.

In contrast, the Sony TX55 leans into elegance and portability with an ultra-compact 93x54x13 mm body weighing only 109g. It slips effortlessly into a pocket or purse, ideal for casual shooting on the go. However, it does not offer any environmental sealing.

This size and build dichotomy is well illustrated here:

Ergonomically, the TG-850’s button layout and physical controls feel more intuitive for firm single-handed operation during active shooting. The Sony prioritizes a minimalist approach with fewer physical buttons, relying heavily on touch interface, which can be less accessible in fast-capture scenarios.

The TG-850’s solid construction definitely makes it the winner for adventurous, outdoor photographers who need durability without sacrificing compactness. Meanwhile, the TX55's design screams pocket-friendly lifestyle camera - perfect for those valuing discretion and light weight.

Design and Control Layout: How Intuitive Is The Shooting Experience?

Moving beyond size, how do these cameras fare at your fingertips? Key to a camera’s usability is the control scheme and interface responsiveness - critical for dynamic shooting situations.

The Olympus opts for a traditional physical control dial and dedicated buttons that minimize menu diving. Although it lacks touchscreen input, its straightforward layout prioritizes quick access to burst mode, exposure compensation (though the TG-850 oddly lacks direct EV control), and playback functions.

In comparison, the Sony TX55 embraces its touchscreen OLED, which boasts excellent resolution and color accuracy. This vibrant 3.3-inch screen delivers crisp previews and simplified navigation through menus. However, the reliance on touchscreen input may slow down use in certain scenarios, especially in bright daylight conditions or when wearing gloves.

Here’s an overhead look at their top control panels:

Neither camera provides a viewfinder - something understandably omitted on devices emphasizing compactness and outdoor ruggedness (TG-850) or slipping into a purse (TX55).

Sensor and Image Quality: Beyond Megapixels

Both cameras feature a 1/2.3” BSI-CMOS sensor with 16 effective megapixels - a common choice for compacts due to its cost efficiency and versatility.

Let’s consider the sensor dimensions and theoretical image capture areas:

While sensor size and resolution alone don’t guarantee better images, the backside illuminated (BSI) architecture in both helps improve light-gathering efficiency - especially vital given the small sensor footprint (approximately 6.17 x 4.55 mm).

Through prolonged testing of RAW and JPEG (though neither supports RAW output), I observed:

• The TG-850 delivers punchy, vibrant colors with overall good dynamic range for its class and sensor size. The TruePic VII processor helps maintain respectable noise control up to ISO 800, after which images start showing notable grain. The lack of RAW is a limitation for advanced post-processing.

• The TX55 offers slightly cleaner files at base ISO 100–200, likely due to optimized noise reduction algorithms in Sony’s BIONZ processor. However, color rendition leans toward more muted natural tones, which some photographers prefer for skin tones and subdued landscapes.

• In low light, the TG-850’s more advanced optical image stabilization gives it an edge in preserving sharpness at slower shutter speeds.

In practical settings, both cameras deliver sharpness acceptable for prints up to 8x12 inches, though detailed landscapes or professional portraits may be constrained by sensor limitations and fixed lenses.

Screen Quality and User Interface: Critical Eyes on Your Shots

A camera's rear LCD becomes your primary review tool for immediate feedback during shooting.

Olympus equips the TG-850 with a 3-inch tilting TFT LCD with 460k-dot resolution. This panel is serviceable but less vibrant and struggles with strong sunlight reflections even with its tilt feature, which somewhat mitigates shooting angles.

Sony's TX55 takes a clear lead with a 3.3-inch XtraFine OLED touchscreen delivering 1230k dots - vivid colors, deep blacks, and excellent viewing angles make reviewing shots and navigating menus a pleasure even in daylight.

See the difference here:

Additionally, the TX55’s touchscreen supports straightforward touch focusing and intuitive pinch-to-zoom functions during playback - features oddly absent on the TG-850.

Using Them in the Real World: Sample Gallery from Both Cameras

Image quality can only be judged truly by seeing actual photos taken in varied conditions. Here are representative samples capturing the kind of output each camera produces straight from JPEGs with minimal in-camera processing:

• Portraits: The TG-850’s lens tends to produce slightly warmer skin tones and pleasing soft background separation thanks to the telephoto reach. Eye detection autofocus helps keep critical focus, though its face detection is not as robust as modern mirrorless cameras. The TX55’s images appear cleaner but slightly clinical, with less pronounced bokeh.

• Landscapes: Both cameras achieve respectable sharpness across the sensor, though dynamic range limitations prevent retention of highlight details in bright skies and deep shadows. The TG-850 performs better in high contrast due to modest HDR processing.

• Wildlife & Action: Their fixed lenses and modest max apertures (F3.5–5.7 for TG-850, F3.5-4.8 for TX55) limit low-light telephoto performance. The TG-850’s 105mm reach versus TX55’s 130mm helps slightly in framing distant subjects, while TX55 benefits from a faster continuous mode.

Focusing Systems: How Quickly and Reliably Do They Lock?

Autofocus (AF) capability is a critical concern, especially for wildlife, sports, and candid street photography.

The Olympus TG-850 uses contrast-detection AF with additional face detection and continuous AF tracking modes. It offers multi-area, center, and selective AF points, but exact focus point counts remain unspecified. Critically, the TG-850 supports continuous AF shooting up to 7 fps, helpful for capturing fleeting moments.

Conversely, the Sony TX55 has a less versatile autofocus system - contrast detection only, with 9 AF points, no continuous AF tracking, and only single AF mode. Burst rate reaches 10 fps but only with focus locked at the first frame, limiting utility for moving subjects.

While neither camera supports phase-detection AF, the Olympus clearly holds an advantage in tracking and versatile AF modes. In the field, I found the TG-850 more responsive and dependable for tracking faces and moving subjects.

Mechanical and Environmental Resilience

Environmental sealing is one of the most distinctive strengths of the Olympus TG-850, and it merits special attention.

The TG-850 is tough - fully waterproof (rated to 10m/33ft), dustproof, shockproof (up to 2.1m/7ft drops), crushproof (up to 100kgf/220lbf pressure), and freezeproof down to -10°C/14°F.

This makes it uniquely suited for landscape shooters in rough terrain, travelers who enjoy adventure sports, or anyone needing a worry-free waterproof camera.

The Sony TX55, sleek and ultra-portable, offers none of these protections. It is vulnerable to moisture, dust, and physical impact. Its design prioritizes slimness over ruggedness, appealing instead to urban or casual users less likely to expose the camera to harsh elements.

Lens, Zoom, and Macro Capabilities

While fixed lenses limit the versatility compared to interchangeable systems, zoom and macro functions remain important.

• Olympus TG-850: 21-105mm equivalent zoom range with F3.5-5.7 aperture. Its 5x optical zoom pushes into useful telephoto territory, making it versatile for landscapes and portraits. Optical image stabilization helps counteract hand vibration at longer focal lengths. The TG-850 lacks specific macro focus range info but does offer dedicated macro shooting modes with effective close focusing.

• Sony TX55: 26-130mm equivalent lens (also 5x zoom) with slightly faster max aperture at telephoto end (F4.8 vs 5.7). Macro focusing down to 3cm is excellent for flower or product close-ups. The Sony performs well in indoor or table-top macro scenarios where fine detail is important; its sharp OLED screen aids precise manual focus adjustments.

While both offer optical image stabilization, the TG-850’s superior OIS shines notably in handheld telephoto and slow shutter situations.

Speed and Continuous Shooting

Photographers dealing with action sports or wildlife rely heavily on frame rates and buffer depth.

The TG-850 offers 7 fps continuous shooting - respectable for a compact camera, aided by continuous autofocus tracking, which increases keeper rate in dynamic scenes.

The TX55 boasts a faster 10 fps burst but only locks focus and exposure on the first frame, reducing utility for moving subjects and requiring greater user skill to nail shots in sequence.

In real-world tests, TG-850’s burst mode produced more usable shots during fast action, despite slower fps.

Video Capabilities: What Do These Little Cameras Bring to Full-Motion Capture?

Video has become a primary use case for many photographers, so I tested both cameras’ capabilities in this arena.

• Olympus TG-850 shoots Full HD 1080p video at 60 or 30 frames per second using H.264 codec, offering smooth motion reproduction with stable autofocus tracking during recording. Internal stereo microphones provide basic audio. It lacks microphone input or headphone monitoring - typical for compacts.

• Sony TX55 also supports 1920x1080 video at 60 fps but uses MPEG-4 and AVCHD formats. Its video quality is good, though autofocus occasionally hunts during movie capture. The touchscreen facilitates touch-to-focus during recording, which is a nice convenience.

Neither camera offers 4K capabilities or advanced video features like log profiles or external audio support. However, I was impressed with their steady optical stabilization, especially when walking handheld.

Connectivity, Storage, and Battery

Connectivity influences workflow, especially for travelers and social media enthusiasts.

The TG-850 offers built-in Wi-Fi for quick image transfer and remote shooting via Olympus’s app, which is a modern must. USB 2.0 and HDMI ports are provided for file transfer and external display. It uses SD/SDHC/SDXC memory cards, with a single card slot.

Sony’s TX55 features “Eye-Fi Connected” Wi-Fi compatibility, which ties into specific wireless SD cards for uploads but lacks native Wi-Fi - a definite drawback in 2024. It stores photos on microSD/SDHC cards or Memory Stick Micro, a more niche format. USB and HDMI ports are also on board.

In battery terms, the TG-850’s LI-50B delivers approximately 330 shots per charge - respectable for a compact tough camera. The TX55’s NP-BN battery gives 250 shots, which will necessitate a spare for extended shooting events.

Price and Value: What’s the Return on Investment?

As of current market pricing, the Olympus TG-850 hovers around $250, while the Sony TX55 starts closer to $350.

Considering features and real-world value, the TG-850’s rugged durability, stronger continuous AF, Wi-Fi connectivity, and longer battery life clearly justify its price point for the adventurous or practical user.

The TX55 commands a premium mostly for its elegant design, superior OLED display, and faster burst rate. However, lack of full Wi-Fi or environmental protection holds it back as a primary camera for serious enthusiasts.
