Drawing on over 15 years of hands-on experience testing thousands of cameras across genres, this comparison offers an exhaustive breakdown of each model’s strengths, weaknesses, and practical performance, aimed particularly at enthusiasts and professionals looking for a detailed purchase guide.

Getting to Know the Cameras: Build, Ergonomics, and Handling

At first glance, the Olympus TG-850 iHS and Sony HX20V share a compact form factor; however, their physical design intentions are markedly different. The TG-850 iHS embraces a ruggedized approach, engineered with environmental sealing to sustain shocks, water immersion, dust, and freezing temperatures - ideal for adventure photographers or anyone needing a tough camera for challenging conditions. Conversely, the Sony HX20V opts for a superzoom compact design focused more on telephoto reach and versatility rather than durability features.

A side-by-side visual comparison vividly illustrates these differences:

Physical Measurements and Grip: The TG-850 (110x64x28 mm, 218 g) is slightly slimmer but packs a welded, sealed body that feels solid in-hand, complemented with textured grips suited for wet or gloved operation. The Sony HX20V (107x62x35 mm, 254 g) is thicker and heavier, accommodating the extensive 20x zoom lens assembly, which affects balance and pocketability.

Controls and Interface Layout: Both omit viewfinders, relying solely on their rear LCDs, but control philosophies diverge. The Olympus employs a simplified control set prioritizing ruggedness, with a tilting 3” 460k-dot TFT screen. Sony features a 3” 922k-dot fixed XtraFine TruBlack TFT, providing crisper preview quality but sacrificing some flexibility in framing angles:

Despite the TG-850's smaller LCD resolution, its tilting articulation grants compositional versatility unsuitable for selfies (no front-facing camera/large front screen) but helpful for waist-level or overhead shooting. Sony’s fixed screen, although sharper, limits ergonomic adaptability.

Sensor, Image Quality, and Processing Power

The heart of any camera’s imaging capability lies in sensor quality and signal processing. Both cameras utilize similarly sized 1/2.3” BSI-CMOS sensors measuring 6.17x4.55mm (28.07mm²), yet with differing resolutions: Olympus TG-850 offers 16MP native resolution, while the Sony HX20V boasts 18MP.

Although the difference in megapixels is modest, Sony’s slightly higher resolution affords larger prints and potentially finer image detail, presuming lens sharpness keeps pace. However, more megapixels on such a small sensor can sometimes result in higher noise levels in low light, as pixel pitch shrinks.

Image Processing Engines: Olympus’s TruePic VII processor and Sony’s BIONZ processor each support JPEG rendering and noise reduction but neither camera supports RAW output - a significant limitation for enthusiasts wanting maximal post-processing flexibility.

ISO Range and Low-Light Performance: The HX20V's ISO range extends from 100 up to 12,800 (compared to TG-850’s 125-6400), suggesting better potential in darker environments. Yet, in practical testing, both struggle above ISO 800, showing the typical noise and detail degradation expected from small-sensor compact cams.

Despite lacking RAW, both benefit from contrast-detection AF with face detection, which helps optimize exposure and focus accuracy under varied conditions. Olympus’s sensor benefits from the lack of electronic viewfinder, focusing solely on LCD previewing complemented by decent optical image stabilization (OIS) to remedy hand shake during slower shutter speeds or longer focal lengths.

Zoom Range and Lens Characteristics

Superzoom capability often guides the choice between compact cameras, especially for travel, wildlife, and sports photography. Sony HX20V shines here with its massive 20x optical zoom spanning 25-500mm (35mm equivalent), delivering reach seldom matched in this class. Its maximum aperture of f/3.2 at wide angle narrows only slightly to f/5.8 at telephoto - balancing light gathering with extended zoom.

The Olympus TG-850, by contrast, covers a 5x zoom range of 21-105mm with an aperture variable from f/3.5 to f/5.7. While less versatile telephoto-wise, its wider angle (21mm vs 25mm) better accommodates landscapes and group shots in tight spaces.

For macro enthusiasts, Sony offers a close focus down to 1 cm, resulting in impressive magnification for detailed close-ups - a functionality Olympus does not specify, limiting TG-850 mainly to standard focusing distances.

The Sony’s lens complexity and optical construction logically compromises its bulk and weight, while Olympus prioritizes a simpler, ruggedized lens assembly without sacrificing optical stabilization.

Autofocus and Performance Responsiveness

Autofocus performance, paramount for wildlife, sports, and street photographers, differs notably between these models. Olympus’s TG-850 features contrast-detection autofocus with continuous and tracking modes and face detection but lacks manual focus options (fixed-lens design prohibits ring manipulation). The number of AF points is unspecified, but practical testing reveals the system copes well in daylight, though struggle arises in low light, as expected from contrast-based AF.

Sony HX20V incorporates 9 focal area points with contrast-detection AF capable of single, continuous, and tracking modes. Unlike Olympus, it includes manual focus toggles, providing creative and precision control.

Rapid burst shooting capability further shakes out differences: Olympus can reach 7 fps continuous shooting for a limited set of frames, whereas Sony offers faster 10 fps bursts but only in single autofocus mode, constraining action capture flexibility.

This difference impacts sports and wildlife scenarios where decisive timing and reliable tracking dictate success. Sony’s superior frame rate combined with longer zoom makes it a more capable option for fast-moving subjects, while Olympus better suits casual shooters needing robustness over raw speed.

Display and User Interface

The rear LCD is a critical interface for composition and menu navigation. Conventional wisdom favors higher resolution and color accuracy in this regard.

While Olympus TG-850 sports a 3” 460k-dot tilting LCD, providing ergonomic advantages for challenging angles (crooked arctic shots or underwater framing), Sony HX20V has a fixed yet higher resolution 922k-dot screen delivering much crisper previews, useful for assessing image sharpness in the field.

Control complexity leans in favor of Sony with manual exposure modes (aperture and shutter priority) and exposure compensation, granting enthusiasts the ability to tailor image parameters precisely. Olympus limits users to auto and scene modes, favoring simplicity but restricting creative latitude.

Both cameras exclude touch interfaces, which nowadays might feel dated but suggest superior battery longevity unaffected by touch demands.
