Selecting the right camera requires meticulous consideration of your photographic needs, technical performance, and the specific demands of your intended use cases. This comparison pits the Olympus TG-610 - a rugged, waterproof compact - from 2011 against the Sony NEX-5, a pioneering entry-level mirrorless from mid-2010. Both cameras target different markets but overlap somewhat in usability for enthusiasts looking at lightweight, portable options.

Having tested thousands of cameras under varying conditions and rigorously analyzed their sensor performance, autofocus reliability, and ergonomics, I aim to provide a comprehensive, unbiased breakdown of these two models. Readers can expect granular insights across all major photographic disciplines - including portrait, wildlife, landscape, and video - to help align choice with both practical requirements and budget constraints.

First Impressions: Handling, Size, and Build Quality

The Olympus TG-610 is designed with durability at its core. It is a compact, pocketable waterproof camera intended for rugged outdoor scenarios. In contrast, the Sony NEX-5 represents an early foray into mirrorless interchangeable lens technology, prioritizing image quality and flexibility over absolute compactness.

Olympus TG-610 Dimensions: 96 x 65 x 26 mm, 190 g
Sony NEX-5 Dimensions: 111 x 59 x 38 mm, 287 g

The TG-610’s noticeably smaller size and lighter weight make it unobtrusive for travel, hiking, or aquatic environments - especially important for photographers prioritizing portability and environmental resistance. The Sony NEX-5, while still compact compared to DSLRs, is thicker and heavier due to its mirrorless design and larger sensor.

Ergonomically, the TG-610 uses a simple, sturdy plastic chassis sealed for waterproof, dustproof, and freezeproof conditions - rated for water immersion up to 3 meters, dust ingress protection, and shock resistance from drops up to 1.5 meters. This makes it highly reliable in harsh weather or underwater shooting. However, its control layout is minimalistic, lacking manual exposure or focus controls, limiting creative flexibility.

Conversely, the Sony NEX-5 offers a more traditional camera grip with a rangefinder-style body. Its build is not weather-sealed, requiring caution in adverse conditions, but it provides superior handling for photography sessions where lens interchange and direct control are paramount.

From the top view, it is evident the NEX-5 includes a dedicated mode dial with aperture and shutter priority modes alongside manual exposure, which the TG-610 completely lacks. The Olympus’s streamlined control panel streamlines point-and-shoot simplicity but at a cost to user control.

Sensor and Image Quality: Compact CCD vs APS-C CMOS

The core difference in image capture technology fundamentally distinguishes these two models.

The Sony NEX-5’s APS-C CMOS sensor provides a much larger surface area - over 13 times greater than the TG-610’s 1/2.3" CCD sensor - enabling superior light gathering, dynamic range, and noise performance. This size advantage also supports much higher native ISO sensitivity (up to 12800), making it substantially better in low-light and night photography.

The smaller TG-610 sensor results in more noise at ISO above 400 and narrower dynamic range, inherently limiting image quality. Moreover, the lack of RAW support constrains post-processing flexibility for professionals and advanced hobbyists.

Despite the similar megapixel count, the NEX-5’s pixels are physically larger, translating into better color depth and reduced chromatic aberration. The TruePic III+ processor in the Olympus is adequate for typical compact camera needs but cannot match the Sony’s Bionz processor in refined noise reduction or image sharpening.

Autofocus Systems and Speed: Simple Contrast Detection vs Advanced Points

Autofocus is a decisive factor in usability across fast-paced scenarios like wildlife, sports, and street photography.

The TG-610 uses a modest contrast-detection AF system combined with basic face detection and single-area focusing. For simple snapshots and macro close-ups, it performs sufficiently, but it struggles with moving subjects and lacks continuous autofocus for tracking.

Sony’s NEX-5 improves autofocus versatility by offering 25 selectable autofocus points and both single-shot and continuous autofocus modes, making it more suited to dynamic photographic contexts such as sports or wildlife. However, it relies purely on contrast detection (no phase-detection), which means AF speed and tracking are adequate but not class-leading.

The Olympus’s face detection is convenient for portraits but limited without eye-detection or animal tracking features found in modern systems. The NEX-5, despite lacking face detect, can be supplemented with select manual focusing or focus peaking on compatible lenses for precise control.

Exposure Control and Manual Operation

The Olympus TG-610 adheres to a fully automatic exposure system without aperture, shutter priority, or manual shooting modes, which confines the user to the camera’s internal metering and exposure decisions. Exposure compensation is not available, inhibiting control over image brightness.

In contrast, the Sony NEX-5 provides full exposure control including aperture priority, shutter priority, and manual modes, supported by custom white balance and exposure compensation settings. This flexibility enables photographers to tailor the exposure and depth of field precisely for creative effect.

Lens Ecosystem and Compatibility

The Olympus TG-610 includes a fixed zoom lens with a 28-140mm equivalent focal length and maximum aperture range of f/3.9 to f/5.9. This lens covers wide-angle to moderate telephoto but offers limited low-light capability due to its modest aperture. There is no option to change lenses, and the macro focus distance is 3 cm, suitable for casual close-up shots.

Sony’s NEX-5 uses the Sony E-mount lens system, offering over 120 compatible lenses ranging from ultra-wide to telephoto primes and zooms, third-party manufacturers included. This makes the system highly versatile, capable of scaling from macro to wildlife photography, portraiture, and specialized applications.

The 1.5x crop factor must be considered when selecting lenses, but the overall adaptability far exceeds the TG-610’s fixed optics.

Video Capability

Video recording is a supplementary feature in both cameras yet differs significantly.

Sony’s NEX-5 supports full HD video at up to 60 fps, incorporating AVCHD compression for higher quality and smaller files. There is no microphone input or headphone jack, limiting audio control, but the video quality is notably better with larger sensor depth of field and reduced noise.

The Olympus TG-610 maxes out at 720p and uses more basic Motion JPEG compression, resulting in larger files and lower image quality. It does benefit from sensor-shift image stabilization, aiding smoother footage, whereas the NEX-5 lacks in-body stabilization and depends on lens-based solutions.

Display and Viewfinder

Both cameras forego an electronic viewfinder, relying on the rear LCD for composition and review.

• The Olympus TG-610 has a fixed 3.0" TFT Hypercrystal III LCD with 920k-dot resolution. The screen is bright and usable in daylight but cannot tilt or swivel, limiting composition flexibility for low or high angle shooting.
• The Sony NEX-5 includes a 3.0" tilting LCD with identical resolution. Although it lacks touchscreen capabilities, the tilt mechanism greatly enhances framing versatility, especially for street, macro, or video users.

Neither camera offers articulated EVFs or touchscreen implementation, which today might be constraining, but the NEX-5’s tilt screen confers a practical edge.

Environmental Resistance and Durability

The TG-610 is purpose-built for challenging environments, with sealed chassis protecting against submersion, dust ingress, and freezing conditions. This makes it ideal for underwater photography, hiking in inclement weather, or travel to rugged destinations.

The Sony NEX-5 lacks any official weather sealing or ruggedized elements, necessitating caution outdoors in wet or dusty conditions.

Battery Life and Storage

The Sony NEX-5 offers superior battery endurance, approximately 50% more images per charge - critical for travel or extended shoots without guarantee of recharging facilities. Both cameras share a single storage card slot, but the Sony’s compatibility with Memory Stick format alongside SD cards is a legacy flexibility benefit.
