Sensor Technology and Image Quality

Sensor performance is the cornerstone of any camera’s image quality. The Olympus TG-870 and Sony A200 utilize different sensor types and sizes, greatly impacting dynamic range, noise handling, and resolution.

The Sony A200’s larger APS-C sensor provides a significantly greater surface area (over 13x larger) than the TG-870’s compact 1/2.3-inch sensor, yielding superior light-gathering ability, dynamic range, and color fidelity. Our experience confirms the A200 maintains better shadow detail, smoother gradations, and higher color depth, consistent with its measured DXOmark color depth (22.3 bits) and dynamic range (11.3 EV).

The TG-870’s backside-illuminated CMOS sensor, while advanced for a compact, is inherently limited by physical size, producing higher noise at elevated ISOs and reduced tonal gradation, especially beyond ISO 800. The lack of RAW output further restricts post-processing flexibility compared to the A200.

For critical image quality, especially in low light or high contrast scenes, the Sony A200’s sensor and RAW support are strong advantages for enthusiasts and semi-professionals.

LCD Screen and User Interface Interaction

Screen design dictates framing and image review quality. The Sony A200 and Olympus TG-870 offer very different implementations in size, resolution, and articulation.

• The TG-870 includes a 3-inch tilting TFT LCD with 921K-dot resolution providing good brightness, viewing angles, and flexibility for shooting at shoulder height or low angles.
• The Sony A200’s 2.7-inch LCD has a lower resolution (230K dots) and is fixed, limiting composition versatility and image review clarity, although its optical pentamirror viewfinder provides eye-level framing with 95% coverage and 0.55x magnification - a critical feature for traditional photographic technique.

For photographers who value live view composition and flexible LCD angles, the TG-870’s tilting screen is a practical benefit. However, the optically superior DSLR viewfinder on the A200 remains preferred for fast, precise framing in bright outdoor conditions where LCD visibility can suffer.

Lens and Autofocus Capabilities

Lens versatility and autofocus performance are crucial, particularly for applied shooting scenarios such as wildlife or sports.

• Olympus TG-870 has a fixed 21-105mm equivalent zoom lens (5x optical zoom, f/3.5-5.7), with macro focusing as close as 1 cm. It features optical image stabilization and contrast-detection autofocus with face detection, continuous, single, and tracking AF modes but no phase detection or eye/animal AF.
• Sony A200 utilizes the Sony/Minolta Alpha interchangeable lens mount with access to over 140 compatible lenses, from fast primes to super-telephoto zooms. It employs a dedicated phase-detection AF system with 9 autofocus points (center cross-type), supporting center, selective, and multi-area focus modes, though without face detection or live view AF.

The A200’s dedicated phase-detection AF system and broad lens ecosystem significantly outperform the TG-870’s fixed-lens contrast-detection system, particularly valuable for action photography, wildlife, and creative depth-of-field control. The TG-870’s macro functionality is commendable for its class, and image stabilization helps handheld shooting at telephoto settings.

Burst Shooting and Shutter Performance

Frame rate capability impacts sports and wildlife photography.

• Olympus TG-870 offers a burst shooting speed of 7 fps, a respectable rate for a tough compact enabling quick capture of fleeting moments.
• Sony A200 shoots at 3 fps, more modest by modern standards but adequate for beginner DSLR users. Its mechanical shutter range extends from 30 seconds up to 1/4000 sec, with flexible exposure modes including manual options.
• TG-870 has limited shutter speed range (4 to 1/2000 sec), no manual exposure modes or shutter/aperture priority, constraining creative control.

For high-speed sequences or dynamic subjects, the TG-870’s faster burst rate is a relative strength in its category, though overall autofocus speed and tracking favor the DSLR in practice.

Weather Sealing and Durability

Ruggedness and environmental resistance are paramount for outdoor and travel photographers.

The TG-870’s comprehensive environmental sealing and protection certifications make it an ideal companion for adventurous photographers who work in wet, cold, or rugged conditions. The Sony A200’s conventional DSLR construction lacks such protections, necessitating care in harsh environments or the addition of protective gear.
