Having spent over 15 years rigorously testing hundreds of cameras across genres - from landscape vistas to fast-motion sports - I bring to this comparison a hands-on, data-driven perspective that should aid serious enthusiasts and professionals alike in identifying which of these cameras might fit their photographic aspirations.

This comprehensive review breaks down the two cameras from every conceivable angle: sensor technology, ergonomics, autofocus, image quality, video capabilities, and genre-specific uses. We’ll also discuss real-world performance and value, supplemented by visual references to deepen understanding.

First Impressions: Size, Handling, and Build Quality

Understanding physical ergonomics is crucial for usability, especially in travel, street, or action photography where comfort and quick access govern image-making potential.

Olympus TG-3: At 112x66x31 mm and 247 g, the TG-3 is considerably larger and more robust than typical compacts. Its defining trait is environmental resilience - the camera is waterproof to depths of 15 meters (50 feet), shockproof from 2.1 meters, freezeproof to −10 °C and crushproof up to 100 kgf. This makes it a go-to choice for underwater, adventure, and harsh-weather photography. The textured, rubberized grip combined with well-placed buttons supports confident one-handed operation, crucial for challenging conditions.

Sony W320: Weighing a mere 117 g and compact at 93x52x17 mm, the W320 focuses on ultracompact portability. Its slim profile fits comfortably into pockets and purses, ideal for everyday street photography or casual snapshots. However, the trade-off is lack of any ruggedness or weather sealing, limiting versatility outdoors.

Top-View Control Layout: Intuitive or Minimalist?

The physical interface drives how quickly photographers can adapt and react to scenes.

Olympus’s TG-3 offers dedicated aperture priority and exposure compensation controls, enabling precise exposure manipulation - an advanced feature absent on the Sony. These tactile buttons convey Olympus’s user-centric design philosophy, promoting creative control even though it remains a fixed-lens compact.

Conversely, the Sony W320’s top surface is minimalist, with a power toggle, shutter release, and zoom rocker. This simplicity lowers learning curves for novices but limits exposure flexibility - a notable omission for enthusiasts wanting finer creative command.

Sensor: The Heart of Image Quality

Both cameras use a 1/2.3-inch sensor measuring 6.17x4.55 mm (approximately 28.1 mm²), a common size in compact classes, but the sensor technology differs markedly.

Olympus TG-3: Employs a 16MP BSI-CMOS sensor coupled with the TruePic VII processor. Backside illumination (BSI) significantly improves low-light sensitivity and noise characteristics compared to earlier sensor types, enhancing raw light capture ability - a critical factor in underwater and night photography.

Sony W320: Uses a 14MP CCD sensor, a dated technology that typically exhibits higher read noise and less dynamic range. Combined with no image stabilization, this sensor limits performance in dim conditions and fast-moving subjects.

In practical testing, the TG-3 delivers cleaner ISO 800 images with better retention of shadow detail and reduced chroma noise. The Sony sensor struggles above ISO 400, showing marked graininess and shadow clipping, restricting its low-light usability.

LCD Screens and Live View Experience

User interface via the rear screen is paramount for composition and image review.

The TG-3 sports a 3.0-inch fixed TFT-LCD panel with 460k dots, brighter and sharper than the Sony’s 2.7-inch 230k-screen. Without touchscreen functionality, the TG-3’s live view still offers engaging overlays, including histograms and a level gauge, aiding critical framing and exposure confirmation.

Sony W320’s lower resolution screen is sufficient for casual framing but lacks feedback overlays or brightness adaptability under sunlight, which can impair outdoor shooting confidence.

Image Quality and Lens Characteristics in Diverse Photography Styles

Both cameras sport fixed zoom lenses with approximately 4x range but differ in focal length extents and apertures:

• Olympus TG-3: 25-100 mm (equiv.), aperture F2.0–4.9
• Sony W320: 26-105 mm, aperture F2.7–5.7

The Olympus’s wider maximum aperture at the short end (F2.0 vs F2.7) allows more light in, improving low-light and shallow depth-of-field capabilities.

Portrait Photography

For capturing nuanced skin tones and pleasing bokeh, aperture and autofocus matter.

• The TG-3 applies face and eye detection autofocus (absent in Sony) with contrast-detection AF, improving accurate focus on subjects, especially important for tight headshot framing. The wider F2.0 aperture also helps create more subject-background separation, although the small sensor limits true bokeh creaminess.
• The Sony, lacking face detection and static aperture control, can struggle to isolate subjects effectively, producing flatter images with less subject pop.

Landscape Photography

• TG-3 processor excels at enhancing dynamic range, preserving highlight details and shadow gradations, especially beneficial in challenging lighting.
• Waterproof and hardy build allows shooting in adverse terrain without protective casing.
• Sony’s limited dynamic range, due to older CCD sensor, means skies and foliage lose nuance when shooting high-contrast scenes.

Wildlife and Sports Photography

• Olympus’s continuous AF and tracking, paired with a 5 fps burst shooting mode (vs Sony’s 1 fps single shot), positively impacts capturing fast-moving wildlife and sports scenes.
• However, a maximum burst of only 5 fps and modest buffer length make it less ideal for professional sports shooting.
• Sony’s limited AF capability and absent burst mode render it ill-suited for action subjects.

Street and Travel Photography

• The Sony W320 shines here owing to portability and discretion. Its silent shutter and small size can attract less attention.
• Olympus’s TG-3, though bigger and heavier, brings versatility with weather sealing - meaning spontaneous shooting regardless of conditions.
• Battery life favors TG-3 with rated 330 shots vs Sony’s unspecified but generally lower endurance.

Macro and Close-up Imaging

• TG-3’s standout macro ability focuses as close as 1cm with a high aperture lens (F2.0), delivering sharp, vivid detail in extreme close-ups.
• Sony requires 4cm minimum focus, limiting intimate detail capture.

Night and Astro Photography

• TG-3’s sensor and processor enable cleaner images up to ISO 6400 (nominal max), good for star fields and long exposures; its minimum shutter speed of 4 seconds (extendable via manual exposure) supports basic night photography.
• Sony’s max shutter speed of 1 second and ISO 3200 cap provide less flexibility under dark conditions.

Video Recording Capabilities

Both models provide video, but differences in resolution and codec matter.

• Olympus TG-3: Full HD 1080p at 30 fps, encoding in H.264 and Motion JPEG for reasonable compression and quality balance. Optical image stabilization (sensor-shift) markedly reduces handheld shake, a critical advantage during movement.

• Sony W320: Limited to VGA (640x480) at 30 fps, in Motion JPEG format only, yielding larger files with lesser quality. No image stabilization is a detriment for video creators.

Microphone and headphone ports are missing on both, limiting audio control. Olympus’s built-in GPS, however, tags location data, a boon for travel vloggers and documentation.

Autofocus Systems in Depth

The TG-3 features contrast-detection autofocus with face detection and continuous AF tracking modes, providing reliable and relatively fast focus acquisition despite the constraints of fixed-lens compacts. During testing, the TG-3 maintained sharp focus on moving subjects, though phase-detection AF (absent here) would offer faster response.

The Sony W320 relies on single-shot contrast-detection AF without tracking or face detection, resulting in occasional hunting and slower focus recomposition when subjects move unpredictably.

Battery and Connectivity

• Olympus TG-3 uses the rechargeable Li-92B battery, rated for approx 330 shots per charge; fairly robust considering rugged design and full HD video.
• Sony W320’s battery life is manufacturer-unspecified, but with smaller battery model NP-BN1 and limited functionality, expect shorter operational duration.
• Wireless connectivity is a strength for TG-3 (built-in Wi-Fi and GPS), supporting immediate sharing and geo-tagging. Sony forgoes wireless features altogether.
• Both cameras support USB 2.0 and HDMI out.
