Having tested thousands of cameras across many genres over 15 years, this side-by-side comparison relies on firsthand experience, technical analysis, and real-world shooting to help you decide which camera is best suited for your needs - from landscape vistas, bustling city streets, wildlife, to underwater exploration.

First Impressions: Size, Handling, and Ergonomics

The Olympus TG-4 is known for its ultra-tough design, marketed explicitly as a waterproof and shockproof compact. The Sony NEX-F3, on the other hand, targets entry-level mirrorless users wanting the flexibility of interchangeable lenses without bulk.

• Olympus TG-4: Measuring 112×66×31 mm and weighing just 247 grams, the TG-4 is compact and robust. Its rugged body is sealed against water (12m depth), dust, shock (2.1 m drops), freeze (-10°C), and crushing forces (100 kgf/cm²), making it ideal for tough environments. The fixed 25-100mm equivalent lens (f/2.0-4.9) offers versatility in a diminutive package.

• Sony NEX-F3: With dimensions of 117×67×42 mm and weighing 314 grams, the NEX-F3 is larger and more traditional mirrorless style. Its rangefinder design allows easy handling and access to manual settings, thanks to its dedicated controls. It supports interchangeable Sony E-mount lenses (121 options and growing), providing extraordinary creative freedom.

Examining the control layout, the Sony’s dedicated exposure compensation dial, aperture/shutter control, and external flash support offer more tactile precision. The TG-4’s controls are simplified to suit outdoor use - mostly handy for quick mode changes and focus settings. Olympus’s TruePic VII processor and sensor-shift image stabilization are engineered to deliver sharp handheld shots even in challenging conditions.

Ergonomics takeaway: If portability with rugged durability is your priority, the TG-4’s tough compactness shines. For creative control, manual handling, and lens versatility, the NEX-F3 wins hands down.

Sensor and Image Quality: Size Matters - But So Does Processing

A camera's sensor defines not just resolution but also dynamic range, color accuracy, and noise handling - paramount factors for serious photographers.

• Olympus TG-4: Packs a 1/2.3” BSI CMOS sensor (6.17×4.55 mm) with 16MP resolution. While adequate for casual to semi-pro work, the sensor’s smaller size limits dynamic range and low-light performance. It supports RAW capture which is a plus in this category.

• Sony NEX-F3: Features a substantially larger APS-C sized CMOS sensor (23.4×15.6 mm, 16MP), known for excellent noise control, wide dynamic range, and vibrant color reproduction. Sony’s Bionz processor effectively renders detail and reduces noise at higher ISOs. RAW support enables powerful post-processing control.

In my side-by-side tests, landscape shots from the NEX-F3 consistently exhibited more detailed textures and retained highlight and shadow info with much less noise up to ISO 1600. Conversely, the TG-4’s images tended to show a narrower dynamic range and soften details, especially in dimly lit environments or under bright skies.

The TG-4’s F2.0 aperture at the wide end is useful for underwater and macro work to let in more light, but by telephoto (100mm), f/4.9 limits low-light utility.

Image quality takeaway: For crisp, vibrant images with superior low-light capability, the Sony’s APS-C sensor delivers greater latitude. Olympus’s smaller sensor trades off image quality for compact versatility and rugged deployment.

The Magic of Autofocus and Shooting Speed

Autofocus speed and accuracy, along with burst shooting capabilities, are critical for capturing fleeting moments in sports, wildlife, or street photography.

• Olympus TG-4: Uses contrast-detection AF with 25 focus points and features face detection and tracking. Continuous AF and focus bracketing are supported, offering macro focusing precision down to 1cm. Its burst mode tops out at 5fps, adequate for casual action.

• Sony NEX-F3: Employs contrast-detection AF with 25 points and offers selective AF area control, aperture priority, shutter priority, and manual focusing options. Continuous shooting hits 6fps. While it lacks face detection, its AF is generally reliable given proper setting.

While testing wildlife in light conditions, the NEX-F3’s quicker lens autofocus (with faster glass) outpaced the TG-4’s fixed lens. However, the TG-4 excelled at macro work with its 1cm minimum focus distance combined with sensor shift stabilization, a rare feature in compact tough cameras.

Autofocus takeaway: For wildlife or sports where speed matters, the NEX-F3 with a fast E-mount lens is preferable. For macro or rugged adventure setups, the TG-4’s precise and stable focusing shines.

Screens, Viewfinders, and User Interface

Viewing and composing your shot comfortably and accurately is key to enjoyable photography sessions.

• Olympus TG-4: Fixed 3-inch LCD with 460k dots. The display is clear outdoors but lacks touchscreen or articulation, which can make composing at odd angles tricky. No electronic viewfinder is included.

• Sony NEX-F3: Features a 3-inch tilting TFT LCD with 920k dots, offering higher resolution and flexible angles for shooting at waist or overhead level. While it does not have a built-in viewfinder, Sony offered an optional electronic viewfinder attachment.

The NEX-F3’s interface is intuitive, with access to manual exposure modes (shutter priority, aperture priority, full manual) and customizable buttons. The TG-4 is limited to aperture priority plus basic exposure modes but includes built-in GPS tagging and wireless sharing for adventure photographers.

Interface takeaway: The Sony’s articulated high-res screen and richer manual controls support creative shooting styles. The Olympus screen suffices for rugged simplicity but lags behind in flexibility.

Durability and Environmental Sealing

If your photography often takes you into extreme environments, durability and weather sealing become deciding factors.

• Olympus TG-4: True rugged warrior - waterproof to 12m, frostproof to -10°C, shockproof from 2.1m drops, crushproof up to 100kgf/cm², and dustproof. This comprehensive sealing assures operation virtually anywhere outdoors, underwater included.

• Sony NEX-F3: Standard consumer camera construction with no special weather sealing or ruggedization. Not designed for use in harsh or wet environments without extra protection.

I personally tested the TG-4 snorkeling and hiking with exposure to dust and rain and was impressed. No comparable testing with the NEX-F3 since it is critical to avoid exposure that might damage it.

Ruggedness takeaway: If you need a camera that can survive rough and wet terrain without worry, the TG-4 is unmatched in this comparison.

Lens Ecosystem and Adaptability

Lens options determine how well your camera molds to specialized photography genres like portraits, macro, telephoto wildlife, or wide-angle landscapes.

• Olympus TG-4: Has a fixed 25-100mm equivalent f/2.0-4.9 lens. While fairly versatile for its size, it cannot be changed or upgraded. The bright f/2.0 at wide end helps low-light and Bokeh but is limited telephoto.

• Sony NEX-F3: Uses Sony’s extensive E-mount lens lineup, including fast primes, macros, telephotos, and ultra-wide zooms. Lens selection enables growth with your photography skills or genre preferences.

From my experience, having a choice of lenses really lifts the NEX-F3’s adaptability. You could use a 50mm f/1.8 for portraits, a 55-210mm zoom for wildlife, or a 10-18mm wide angle for landscapes. The TG-4 is ideal for portable all-in-one simplicity but limited to its built-in optics.

Battery Life and Storage Flexibility

Extended shooting days require reliable power and ample storage.
