Olympus TG-2 iHS vs Sony DSC-H55: An Expert Comparison for Photography Enthusiasts

Choosing the right compact camera often demands a well-informed balance between performance, features, and practicality. Today, I’m diving deeply into two intriguing options in the compact camera arena: the Olympus Tough TG-2 iHS and the Sony Cyber-shot DSC-H55. Each excels in different scenarios, offering contrasting strengths that cater to specific photography needs.

Having tested thousands of cameras myself over the past 15 years, I’ll walk you through everything you need to know - from sensor performance and ergonomics to autofocus speed and real-world usability. This guide is meant to give you a detailed, honest comparison to help you decide which model might best fit your photography style and budget.

Getting to Know the Competitors: Overview and Physical Attributes

Both the Olympus TG-2 iHS and Sony H55 are fixed-lens compact cameras with a 1/2.3" sensor size, but that similarity only scratches the surface. They target distinct user priorities. The TG-2 iHS is designed primarily as a rugged, tough camera for adventurous shooting, while the H55 leans towards offering an extensive zoom range in a pocketable form.

Here’s a quick snapshot of their physical profiles and key specs to set the stage:

Design and Build

The Olympus TG-2’s strong suit is ruggedness. Its crushproof and waterproof design (up to certain limits) makes it perfect for capturing shots in tough outdoor environments - something I’ve personally tested in harsh conditions, from mountain hikes to beach outings. The Sony H55 is more a travel and casual shooting option - compact, lightweight, but without weather sealing.

Looking at the form factor, the TG-2 is slightly bigger and heavier due to its reinforced body and internal components designed for shock and water resistance. The Sony has a more traditional small compact profile, great for slipping into a bag without adding noticeable weight.

Sensor and Image Quality: Delving Into the Heart of the Cameras

Sensor technology and resolution are critical for image fidelity, especially when you plan to crop images or print large.

• Olympus TG-2 iHS: Uses a 12MP 1/2.3" Backside Illuminated CMOS sensor, which improves light gathering and reduces noise - an asset in lower light scenarios. BSI sensor technology usually offers better dynamic range and color reproduction compared to traditional CMOS or CCD.

• Sony DSC-H55: Equipped with a 14MP 1/2.3" CCD sensor. CCD sensors, common in older compacts, often render colors nicely in bright conditions but tend to struggle with noise control and dynamic range compared to BSI-CMOS sensors.

Real-World Testing: When shooting outdoors in bright light, both deliver decent image quality with vibrant colors and sharp details. However, I noticed the Olympus TG-2 provides cleaner images at higher ISO settings (up to ISO 6400) compared to the Sony H55, which maxes out at ISO 3200 and shows more noise generally in dimmer conditions.

Resolution and Detail

While the Sony H55’s 14MP sensor sounds advantageous on paper, in practice, the CCD sensor technology doesn’t capture fine detail as crisply as the BSI-CMOS on the TG-2 when viewing on a monitor or making moderate-size prints. The Olympus also has a slight edge in dynamic range, preserving more shadow and highlight detail.

If image quality, especially in mixed or challenging lighting, is your priority, the TG-2’s sensor architecture gives it a practical advantage.

Lens and Zoom: Reach and Optical Capabilities

Both cameras feature built-in zoom lenses with different focal length ranges and aperture characteristics:

• Olympus TG-2: 25-100mm with a bright f/2.0 maximum aperture at the wide end. This lens allows good low-light capture and delivers a shallow depth of field for bokeh-rich portraiture despite its compact sensor.

• Sony H55: 25-250mm (10x zoom), but with a narrower aperture, maxing at f/3.5-f/5.5. This longer zoom is great for reaching distant subjects such as wildlife or sports but sacrifices light intake and shallow depth of field for flexibility.

What this means in practice:

• If you want a versatile lens with good light-gathering capability for portraits and moderate telephoto use, the TG-2's 4x zoom with wider aperture is impressive.

• If your focus is on distant subjects or landscapes where zoom reach matters more than aperture width, the Sony H55’s 10x zoom is particularly useful - though expect compromises in sharpness at the long end.

Autofocus Performance: How Fast and Accurate Are They?

Autofocus experience often separates a satisfying shooting experience from a frustrating one, especially for moving subjects.

• Olympus TG-2 uses contrast detection autofocus with face detection and tracking features. It supports single, selective, center, and multi-area AF modes. While it lacks phase detection, in my testing, the face detection is reasonably responsive outdoors, but hunting can occur in low light.

• Sony H55 also relies on contrast detection, but with 9 focus points and center-weighted AF. Unfortunately, it lacks face detection and tracking capabilities, limiting its performance for moving or complex scenes.

Continuous AF and Tracking: The TG-2 supports AF tracking, which can help keep moving subjects in focus. I tested this with pets and kids and found it noticeably more reliable than the Sony H55, which struggled to maintain focus on subjects in motion.

Shooting Speed and Burst Performance

For sports or wildlife, continuous shooting speeds can be important:

• Sony H55 offers a faster burst rate at 10 fps, useful for capturing quick action sequences despite its sensor limitations.

• Olympus TG-2 has a more modest 5 fps burst rate.

In practical shooting conditions, the faster fps of the Sony is good, but the autofocus tracking weaknesses limit its usefulness in fast-paced action compared to cameras with hybrid AF systems.

Stabilization and Handling in the Field

Both cameras feature image stabilization but differ in approach:

• TG-2 iHS: In-body sensor-shift stabilization delivers steady shots regardless of lens zoom, which particularly helps at the telephoto end or in video capture.

• Sony H55: Employs lens-based optical stabilization which is effective mostly at mid-range zoom.

My experiences show the Olympus system offers a more consistent stabilizing effect, especially when shooting handheld in lower light or at longer focal lengths.

User Interface, Screens, and Controls

• The TG-2 features a bright 3.0-inch OLED screen with 610k-dot resolution, making it easy to review images and frame shots in bright daylight.

• The Sony H55’s 3.0-inch LCD has just 230k dots resolution, noticeably dimmer and grainier, which can frustrate outdoor shooting or precise manual composition.

Neither model has a touchscreen or built-in viewfinder, but the Olympus’s brighter display adds to usability in challenging conditions.

The TG-2’s ergonomic design includes well-separated, tactile buttons and a simple control layout optimized for quick adjustments. The Sony has a more compact layout, which is functional but can feel cramped during prolonged shooting sessions.

Video Capabilities: Which Records Cleaner Motion?

For casual video shooters, here’s how the two compare:

• Olympus TG-2 iHS supports Full HD (1920x1080) recording at 30 fps in H.264, offering better video quality and detail.

• Sony H55 tops out at HD 720p resolution at 30 fps in MPEG-4, which is noticeably lower in quality compared to the TG-2.

Neither has microphone inputs or advanced video controls, limiting their use for serious videographers, but the Olympus camera is clearly better suited to casual Full HD video capturing.

Outdoor Durability and Special Features

The Olympus TG-2 iHS shines in durability. Its environmental sealing protects it against crushing forces and water immersion, backed by my hands-on testing in rugged conditions from rain-splattered hiking trails to dusty construction sites.

The Sony H55 offers no weather resistance, making it better suited to indoor or fair-weather shooting.

The TG-2 also incorporates GPS tagging, a useful feature for travel photographers wanting to log locations precisely, an absence on the Sony H55.

Battery Life, Storage, and Connectivity

• The TG-2 uses a rechargeable Li-ion Battery Pack (Li-90B) rated approximately 350 shots per charge, which I found sufficient for a day of active shooting. It accepts one SD card slot.

• The Sony H55 uses the NP-BG1 battery. Official shot counts vary but tend to be slightly lower in real use. It supports multiple formats including Memory Stick Duo and SD cards.

Both cameras offer USB 2.0 connectivity for file transfer but lack wireless or Bluetooth options, which is not surprising given their release eras.
