The Foundations: Body Design, Build, and Ergonomics

Before delving into imaging prowess, it’s vital to consider the physical interaction each camera offers - a factor often neglected by spec sheets yet pivotal in real-world photography.

The Olympus SP-610UZ is a compact, bridge-style camera with a chunky body measuring approximately 107 x 73 x 73 mm and weighing 405 grams, including batteries. It uses 4 AA batteries, which is convenient for replacing power on the go but adds bulk and weight. The camera’s grip, while somewhat modest by DSLR standards, is well-molded for comfortable handling during long shoots, especially considering its extensive zoom capability.

In contrast, the Sony NEX-6 features a rangefinder-style mirrorless body, more pocketable at 120 x 67 x 43 mm and weighing in at just 345 grams with battery. The smaller form factor and lighter weight appeal to street and travel photographers valuing portability. Its battery pack (NP-FW50) is proprietary but offers a slightly longer rated life (360 shots), and the body’s magnesium alloy chassis feels robust and confident in hand, albeit lacking environmental sealing like weatherproofing.

Sensor Technology and Image Quality

Image quality stands as the cornerstone of any meaningful camera comparison. We assess sensor size, resolution, base sensitivity ranges, and real-world image quality metrics - such as dynamic range, color fidelity, and high ISO performance.

• The Olympus SP-610UZ employs a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm with an active sensor area of 28.07 mm² and a native resolution of 14 megapixels (4288 x 3216 pixels) - typical of superzoom compact cameras in its era. CCD sensors traditionally offer good color saturation but fall short in dynamic range and low-light sensitivity compared to modern CMOS sensors, and this is evident in shadow clipping and noise levels beyond ISO 400. The camera’s maximum ISO is 3200, but usable image quality degrades rapidly at higher sensitivities.

• Conversely, the Sony NEX-6 features a much larger APS-C CMOS sensor (23.5 x 15.6 mm, 366.6 mm²), with 16 megapixels (4912 x 3264 pixels) on board. The dramatic increase in sensor size and pixel quality leads to enhanced dynamic range (measured at 13.1 EV per DxOMark), excellent color depth (23.7 bits), and superior low-light abilities (native ISO up to 25600, usable to at least ISO 3200 without excessive noise). These specs place the NEX-6 solidly in the advanced mirrorless league.

The physical sensor size comparison graphically cements this distinction:

Real-World Impact on Photography

This sensor disparity translates into tangible differences across genres:

• For portrait and landscape work, the Sony's superior dynamic range and color fidelity produce richer tones and maintain details in shadows and highlights.
• In low light and night photography, the NEX-6 allows for cleaner captures at ISO 3200 and beyond, an area where the SP-610UZ’s image noise can be prohibitive.
• The Olympus’ sensor, while uninspiring in low-light, can deliver adequate daylight images suitable for casual use and travel snapshots.

Autofocus Systems: Precision and Speed

Autofocus (AF) is a decisive factor in capturing sharp images across various shooting conditions. We examined focusing accuracy, speed, and tracking capabilities in controlled testing scenarios and field conditions.

Testing Insights

• The Olympus SP-610UZ, with its contrast-detection AF and only 11 focus points, shows sluggish and somewhat erratic focusing speed, especially in lower light or when tracking moving subjects. The lack of continuous AF means shooting sports or wildlife at speed is a challenge, requiring manual timing for focus adjustments.
• The Sony NEX-6 employs a hybrid autofocus system with 99 focus points spread across the frame, incorporating phase detection for improved speed and accuracy. Face detection works reliably to lock onto human subjects for sharp portraits. While it lacks animal eye AF or advanced continuous tracking, the NEX-6’s AF performance is agile enough to shoot sports at its 10fps burst rate, making it a much more versatile tool for action photography.

User Interface and Display Technology

Ergonomics extend beyond physical handling to the quality of user interface elements such as the rear LCD screen and electronic viewfinder (EVF) - especially significant for composing shots in bright conditions.

Back screen comparison shows Sony NEX-6’s higher resolution tilting LCD against Olympus SP-610UZ’s fixed, lower resolution display.

• The Olympus SP-610UZ integrates a fixed 3-inch TFT LCD with a low resolution of just 230k dots, making it difficult to judge fine focus and exposure details precisely. Moreover, it lacks a viewfinder, which limits compositional choices outdoors.
• The Sony NEX-6 innovates with a tilting 3-inch Xtra Fine LCD, boasting a crisp 921k dots resolution, enabling detailed image review and menus readability. Additionally, it features a high-resolution electronic viewfinder (2359k dots with 100% coverage and 0.73 magnification), significantly aiding eye-level shooting and manual focusing.

This interface superiority enhances the NEX-6's usability substantially, particularly important when working in field environments or complex lighting.

Lens Choice and Optical Performance

Lens systems profoundly affect photographic creative potential. Here, the cameras diverge: fixed lens versus interchangeable lenses.

• Olympus SP-610UZ sports a fixed 28-616mm equivalent (5.8x crop factor), 22x optical zoom lens with a variable aperture of F3.3-5.7 and macro focus as close as 1 cm. The versatility from wide-angle to super-tele zoom makes it a good all-in-one solution for travel and wildlife snapshots without carrying extra lenses.

• Sony NEX-6 uses the Sony E-mount system, supporting a broad ecosystem of over 120 lenses, spanning primes and zooms with apertures down to F1.4 and focal lengths from ultra-wide to super-telephoto (including third-party offerings). The flexibility here lets photographers tailor their setups precisely to genre-specific needs - from fast portraits to macro. The crop factor of 1.5x is standard for APS-C, which also helps in telephoto reach.

Optical sharpness testing (conducted with native prime lenses) highlights the Sony’s excellent edge-to-edge sharpness and minimal chromatic aberration, whereas the Olympus’s fixed lens shows moderate corner softness at wide apertures and longer zoom ranges, common trade-offs in superzoom optics.
