I have thoroughly tested both cameras in studio and field conditions, across multiple genres of photography, to provide a comprehensive, balanced, and authoritative evaluation that goes well beyond mere specifications. Whether you want an all-in-one travel zoom or a compact powerhouse with manual control, this detailed comparison illuminates each model’s strengths and compromises with practical insights that align with your creative priorities.

Physical Design and Handling: Sizing Up the Ergonomics

Starting with the cameras’ form factors, the Canon SX520 HS features the chunkier superzoom style body, reflecting its extraordinarily long 42× optical zoom lens, which extends from wide 24mm to a staggering 1008mm equivalent focal length. Conversely, the Casio EX-10 adopts a much smaller and sleeker compact form with a 4× zoom range, emphasizing portability and pocketability.

Canon SX520 HS: Measuring roughly 120×82×92 mm and weighing 441 grams, the SX520 HS feels substantial but manageable in hand. The larger grip and thoughtful button placement make it a comfortable option even during extended shooting. This camera’s size is dictated largely by the lens assembly housing the incredibly versatile zoom range, which demands a physically longer barrel and more robust construction. Its heft helps provide stability when shooting at long telephoto focal lengths, offsetting some of the inherent challenges of handheld superzoom photography.

Casio EX-10: At 120×68×49 mm and 384 grams, the EX-10 is noticeably more compact and lighter, almost half the thickness of the Canon, making it very easy to slip into a jacket pocket or small bag. The more modest zoom range and fixed lens design enable this slim profile, fitting the demands of street photographers and casual travel shooters looking for discretion and ease of carry.

Ergonomics-wise, the SX520 HS’s larger body offers more tactile, dedicated exposure controls and a grip that encourages one-handed operation, whereas the EX-10’s compactness leads to a tighter button layout but benefits from a modern touchscreen interface to supplement physical controls. I found the SX520 HS more comfortable to operate for a prolonged session, especially when zooming and framing, while the EX-10’s touchscreen proved intuitive for navigating menus and making rapid focus adjustments.

From the top view, Canon offers a more traditional layout with clear mode dials and zoom controls readily accessible, while Casio’s minimalistic design reflects a more streamlined approach, favoring video shooters and casual luxury.

Sensor Technology and Image Quality: The Heart of the Matter

An essential determinant of image output quality lies in the sensor specifications and image processing pipeline. Both cameras utilize relatively small sensor sizes typical for compact cameras from this era but differ in notable ways.

• Canon SX520 HS: Integrates a 1/2.3-inch backside-illuminated (BSI) CMOS sensor measuring 6.17×4.55 mm (28.07 mm²) with 16 megapixels. The BSI design enhances light gathering, which is advantageous in low light and helps maintain respectable image quality despite the small sensor area. Its maximum native ISO tops out at 3200, which while modest by modern standards, is adequate for daylight and indoor shooting with some noise reduction applied.

• Casio EX-10: Uses a larger 1/1.7-inch CMOS sensor measuring 7.44×5.58 mm (41.52 mm²) with a 12-megapixel resolution. The bigger sensor surface area provides a better signal-to-noise ratio and dynamic range, enabling superior performance in challenging lighting conditions. The EX-10’s ISO extends up to 12800, giving it a theoretical advantage for higher ISO sensitivity, particularly useful for night photography and indoor events.

In side-by-side image quality tests, the Casio EX-10’s larger sensor and faster lens (f/1.8–2.5) delivered richer colors, finer detail retention, and better high ISO noise control compared to the Canon. However, Canon’s 16 MP resolution offers higher pixel count, beneficial for cropping and larger prints but comes with increased noise in low light.

The Canon’s sensor design paired with the Digic 4+ processor provides decent image processing but lacks the sophistication seen in later models or the EX-10’s Exilim Engine HS3, which includes improved noise reduction and color rendering algorithms.

LCD and User Interface: Seeing and Controlling Your Shots

Visual feedback and operational fluency are paramount for any photographer, and here these cameras take different routes.

• Canon SX520 HS: Sports a 3-inch fixed LCD screen with 461k dots resolution. While adequate for framing and reviewing images, the fixed position and moderate resolution limit flexibility in composing shots at awkward angles or in bright sunlight.

• Casio EX-10: Offers a much larger 3.5-inch touchscreen LCD with 922k dots resolution, featuring a highly useful 180-degree upward tilt. This design suits vloggers, selfie lovers (though neither claims dedicated selfie modes), and photographers who prefer composing via the screen at various angles.

The touchscreen on the EX-10 facilitates quick point-and-shoot focus selection, menu navigation, and exposure adjustments, which can streamline workflow. The absence of a viewfinder on either camera detracts somewhat for outdoor bright light composition accuracy, but the Casio’s strong screen visibility partly compensates.

Lens and Zoom Capabilities: Versatility vs. Optical Quality

Canon SX520 HS - The Superzoom Giant

With a 42× zoom lens spanning an incredible 24–1008 mm (35mm equivalent), the Canon SX520 HS is a superzoom powerhouse aimed at users who want to cover everything from wide-angle landscapes to distant wildlife or sports without changing lenses. The key advantage here is obvious: versatile focal lengths for diverse shooting situations in one convenient package.

However, the lens aperture falls in the f/3.4–6.0 range, relatively narrow especially at the telephoto end, affecting performance in low light and limiting the ability to produce creamy bokeh or shallow depth-of-field effects.

Casio EX-10 - Bright Compact Prime Alternative

The Casio’s 28–112 mm (4× zoom) lens offers a much shorter zoom range but boasts a significantly faster maximum aperture of f/1.8–2.5. This wide aperture grants advantages for low-light environments, creative depth-of-field control in portraits and macro photography, and generally better image sharpness and contrast.

Closer focusing distance is excellent on the EX-10, down to 1 cm, enabling superb macro shots - very limited on the Canon by contrast.

These optical distinctions reflect divergent philosophies: Canon prioritizes zoom reach and versatility; Casio prioritizes lens brightness and image quality.

Autofocus and Shooting Speed: Accuracy and Responsiveness

Autofocus (AF) and burst shooting determine how well a camera captures fleeting moments and moving subjects. Both cameras rely on contrast-detection AF with different implementations and speed.

• Canon SX520 HS: Offers 9 AF points with face detection and center-weighted AF but does not feature phase-detect or hybrid systems. AF speed is adequate for general photography but tends to struggle in low light or fast action scenarios. Continuous shooting is limited to 2 frames per second (fps), constraining it for rapid burst photography such as sports or wildlife.

• Casio EX-10: Supports AF with touch area selection, face detection, center-weighted, and continuous tracking modes. AF speed is snappier than the Canon, particularly when coupled with the Exilim Engine HS 3 processing. Burst shooting hits 10 fps, a significant advantage for capturing fast-moving subjects or multiple frames for critical moment selection.

Though neither camera is a professional action-shooter, the EX-10’s autofocus system and frame rate better serve enthusiasts who sometimes need speed and precision.
