This article will leverage hands-on experience spanning thousands of camera evaluations, blending real-world field tests, rigorous technical scrutiny, and user-centered assessments to guide you in choosing the best fit for your photography ambitions. We will systematically dissect these cameras across multiple dimensions - ranging from sensor technology and autofocus systems to ergonomics, shooting performance across genres, and overall value.

Before we unravel specifics, a side-by-side glance at their physical form helps frame expectations for handling and portability.

A Battle of Ergonomics and Portability: Size, Weight, and Handling

Examining physical dimensions and ergonomic layouts early on influences every subsequent photography experience - after all, no matter how capable a camera is, if it feels awkward in hand or is too bulky for your style, it may discourage use.

• Canon SX520 HS weighs in at 441 grams and measures 120×82×92 mm, classifying it firmly as a compact superzoom but notably on the heavier and bulkier side for pocket use.
• Nikon S5100, by contrast, is a very lightweight 132 grams with diminutive dimensions of 97×57×22 mm, epitomizing pocketable portability.

The SX520 HS’s bulk directly supports its 42x zoom lens, offering extraordinary reach for telephoto enthusiasts but at the cost of compactness. In contrast, the S5100’s slender body houses a 5x zoom lens, restricting telephoto flexibility but ensuring near-effortless handling and convenience - ideal for casual street shoots or travel where minimizing gear weight is paramount.

Ergonomically, the Canon’s deeper grip and more substantial body help with stable one-handed shooting, especially important at extreme zooms to reduce camera shake. Conversely, the Nikon’s tiny, thin shell can feel cramped for users with larger hands, potentially affecting comfort on longer shoots.

Navigating physical controls and interfaces also defines the user experience.

Control and Interface Layout: Intuitive Handling or Minimalist?

The Canon SX520 HS offers a more traditional camera layout: a mode dial, dedicated zoom toggle around the shutter release, and buttons for exposure compensation, ISO, and quick access to menus, providing a photographer more tactile control. This design caters well to photographers who appreciate manual influence on exposures and more nuanced settings adjustments. However, the absence of a touchscreen may limit rapid interactions common in modern compacts.

In contrast, the Nikon S5100 simplifies controls to cater to point-and-shoot users: a mostly automatic interface lacking dedicated manual exposure modes or advanced customizations. Its lack of buttons besides essential ones and no touchscreen weighs on its classification as an entry-level compact prioritizing ease of use over complexity.

Moving onto the sensor heart: both cameras sport sensors of identical sizes but differing technologies, a key determinant of image quality potential.

Sensor Technology and Image Quality: BSI CMOS vs CCD in Small Sensor Cameras

Both cameras use a 1/2.3" sensor measuring approximately 6.17×4.55 mm (28 mm²), a standard size in the compact category balancing sensor cost, zoom integration, and image quality. Yet, beneath the common size, their sensor technologies diverge markedly:

• The Canon SX520 HS employs a BSI-CMOS sensor with 16 megapixels, an advanced sensor design enabling improved light gathering efficiency, reduced noise, and better dynamic range compared to older technologies. CMOS sensors also support faster readout speeds and flexible autofocus modes.
• The Nikon S5100 utilizes a CCD sensor with 12 megapixels. While CCDs traditionally offered good image quality and color fidelity, their noise performance at high ISO and speed is generally inferior to modern CMOS designs.

In practice, the Canon’s sensor advantage translates into better low-light capability, cleaner images at higher ISO settings (up to ISO 3200), and generally richer tonal gradation. The Nikon’s sensor, limited to ISO 1600, tends to produce more noise and loss of fine detail under dim conditions, restricting its versatility beyond bright daylight.

The higher resolution of the Canon also provides extra cropping freedom or potential for larger prints - very useful for wildlife or landscape photographers wanting detail retention.

Moving to the rear interface, we consider screen real estate and usability for image preview and menu navigation, which significantly affect everyday shooting comfort.

Both cameras feature fixed LCD screens, with Sony’s decision typically favoring fixed to contain costs and form factor, but here they differ in size and resolution:

• The Canon SX520 HS has a 3-inch screen at 461k-dot resolution, delivering a reasonably sharp and bright display for composition and image reviewing.
• The Nikon S5100 sports a slightly smaller 2.7-inch screen with a 230k-dot resolution, which is notably lower, causing less detailed previews and visibility struggles in bright outdoor conditions.

Neither camera incorporates touchscreen capabilities, which have since become common in newer models, limiting some intuitive focusing or menu navigation conveniences. The Canon’s larger and higher resolution screen improves usability, especially when manual focusing or zooming in on images.

Next, let’s explore autofocus systems, critical for producing sharp images under different shooting scenarios.

Autofocus Systems: Speed, Accuracy, and Flexibility

The autofocus (AF) technology employed heavily influences a shooter’s success rate in capturing sharp images across diverse subjects and lighting conditions.

• The Canon SX520 HS features 9 AF points, contrast-detection AF, along with face detection and continuous AF tracking. While not boasting phase-detection AF (common in DSLRs), Canon’s optimized algorithms provide reasonably swift and accurate focusing, especially in well-lit scenes. Face detection elevates portrait and candid photography ease.
• The Nikon S5100 has an unspecified, basic contrast-detection AF system with limited area coverage and no face or eye detection capabilities.

In real-world shooting, the SX520 HS’s AF system shows a clear advantage when tracking moving subjects such as in casual sports or wildlife scenarios, albeit still limited by the processor speed and sensor frame rate. The Nikon struggles with focus lock in less favorable light or action conditions, often requiring manual refocus attempts.

Regarding continuous shooting capability (burst mode), the Canon supports 2 fps (frames per second), suitable for slow action but insufficient for rapid sports or wildlife sequences, whereas Nikon does not specify continuous shooting, indicating limited or absent burst functionality.

Having outlined the mechanical and technical underpinnings, let’s consider the cameras’ performance across photography genres.
