In an era where photographic technology caters to increasingly distinct niches, the choice between a rugged compact camera and an entry-level mirrorless model can be challenging. Here, we compare two cameras that are fundamentally different yet hold appeal for enthusiasts seeking specialized or adaptable photographic tools: the Olympus Tough TG-2 iHS, released mid-2013 as a durable, waterproof compact, and the Sony Alpha NEX-5N, Sony’s 2011 foray into mirrorless rangefinder-style cameras offering an APS-C sensor and interchangeable lenses.

This comprehensive comparison dissects each model’s performance, strengths, and considerations across a wide spectrum of photographic disciplines, practical usability, and technical specifications. It draws from extensive hands-on testing experience, backed by precise measurement methodologies and real-world scenario evaluations.

Physical Design and Ergonomics: Handling Two Contrasting Philosophies

The Olympus TG-2 iHS and Sony NEX-5N present markedly different approaches to camera design due to their targeted userbase and operational contexts.

• Olympus TG-2 iHS: A compact, waterproof body measuring 111 x 67 x 29 mm and weighing 230 g, the TG-2 is engineered for durability and portability. Its ergonomic design favors users in outdoor, adventure, and harsh environment photography, offering a crushproof body and sensor-shift image stabilization within a ruggedized shell. The fixed lens simplifies operation but limits manual control.

• Sony NEX-5N: Measuring 111 x 59 x 38 mm and weighing 269 g, the NEX-5N’s “rangefinder-style” mirrorless body emphasizes compactness for an interchangeable-lens camera, featuring a tilting 3” TFT LCD and versatile grip profile typical for its class. An eye toward ergonomic customization and flexibility is evident but it lacks environmental sealing, which offsets suitability for inclement conditions.

The TG-2’s superior weather durability is a decisive ergonomic advantage for photographers active in extreme conditions. Meanwhile, the NEX-5N’s larger but unsturdy frame makes it better suited for controlled environments where handling precision and lens interchangeability matter more.

Sensors and Image Quality: Size and Performance Disparities

At the core of image quality differences lie sensor technologies and resolutions:

• Olympus TG-2 iHS: Employs a 1/2.3-inch BSI-CMOS sensor with 12 megapixels resolution. This sensor size (6.17 x 4.55 mm) is typical for compact cameras, limiting image quality in terms of dynamic range and noise performance, particularly in low light. The sensor incorporates an anti-aliasing filter and covers a sensor area of approximately 28.07 mm².

• Sony NEX-5N: Houses a significantly larger APS-C CMOS sensor (23.4 x 15.6 mm), delivering 16 megapixels effective resolution with no low-pass filter attenuation. This sensor area (365.04 mm²) is over 13 times greater than the TG-2, granting superior dynamic range (about 12.7 EV per DxOMark testing) and enhanced low-light performance, with maximum ISO up to 25,600.

In practical terms, the Sony’s sensor technology provides greater detail retention, better color depth (DxO score 23.6 bits), and markedly improved signal-to-noise ratios beyond ISO 800, critical for professional workflow and large print applications. The small compact sensor in the TG-2, although adequate for casual photography and output limited to online or small prints, will yield less flexibility for post-production or high-dynamic-range landscapes.

Autofocus Systems and Focusing Versatility

Autofocus (AF) performance critically impacts various photographic disciplines:

• TG-2 iHS: Uses contrast-detection AF with face detection and center-weighted metering, supplemented by limited tracking capabilities in stills. Manual focus is not supported. The fixed lens simplifies focusing but reduces versatility, especially for manual focus and precision macros.

• NEX-5N: Features 25 AF points employing contrast-detection augmented by a Bionz processor. It supports touch AF on a tilting screen, offering flexible focus point selection and improved focus accuracy. Manual focusing is available via interchangeable lenses, with support for focus peaking (in certain firmware), enhancing macro and creative control.

Testing reveals that while the TG-2’s AF is adequate for stationary subjects in bright light, it can be slower and less reliable in challenging focusing situations. The NEX-5N excels in autofocus speed (up to 10 fps burst) and precision, particularly for selective focus or shallow depth of field applications, essential for portraits and wildlife photography.

Lens Ecosystem and Optical Performance

This section embodies one of the most fundamental divergences between the two cameras:

• TG-2 iHS: Fixed 25-100mm equivalent f/2.0-4.9 zoom lens with a macro focus range down to 1 cm. While versatile for a variety of compact camera scenarios, this lens’s optical performance is tailored for waterproof and rugged conditions, often involving compromises in sharpness, distortion correction, and bokeh quality compared to larger, dedicated lenses.

• NEX-5N: Compatible with Sony E-mount lenses, which as of 2011 provided access to over 120 lenses including primes and zooms optimized for various applications - from ultra-wide to telephoto, macro, and portrait. This flexibility allows users to tailor their gear for professional needs or creative experimentation, including sharp fast-aperture optics with distinct rendering and depth-of-field control.

For photographers prioritizing ultimate image quality, selective aperture control, or specialized optics (telephoto for wildlife, macro for closeup work), the NEX-5N’s lens ecosystem provides significant advantages over the TG-2’s integrated solution.
