Head-to-Head Analysis: Casio EX-H15 vs Sony WX500 – Compact Cameras in the Small Sensor Superzoom Segment

In the realm of compact cameras, particularly within the small sensor superzoom category, two models often surface in discussions from the last decade: the Casio EX-H15 and the Sony Cyber-shot DSC-WX500. Though both cameras belong to compact series tailored for enthusiast and casual users valuing portability paired with a versatile zoom range, they were launched in very different market contexts (2010 vs 2015 respectively). This review undertakes a rigorous, feature-by-feature comparative analysis grounded in extensive hands-on testing methodologies. It provides deep insights into their core technical attributes, real-world photographic capabilities, and practical value proposition across a wide range of photographic disciplines.

Sensor Technology and Image Quality Overview

Casio EX-H15: A 2010 Legacy CCD Sensor

The Casio EX-H15 employs a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm with a 14-megapixel resolution (4320 x 3240 pixels). CCD sensors were predominant in compact cameras of its generation, known for relatively good color depth and low noise at base ISO, but typically limited in dynamic range and high ISO performance compared to later CMOS technologies. The EX-H15’s maximum native ISO is 3200, with a minimum of ISO 64.

Sony WX500: An Advanced BSI-CMOS Sensor

Fast forward five years, the Sony WX500 integrates a similarly sized 1/2.3-inch BSI-CMOS sensor, also measuring 6.17 x 4.55 mm but boasting 18 megapixels (4896 x 3672 pixels). The backside-illuminated CMOS design substantially improves light gathering efficiency, augmenting dynamic range and low-light noise handling. The native ISO range extends from 80 to an impressive 12800, enabling better performance under challenging lighting.

Image Quality and Resolution Impact:

The 18MP sensor in the WX500 allows for finer detail capture, which becomes evident when pixel-peeping or printing large format images. The Casio EX-H15’s 14MP sensor, while competent, tends to produce softer imagery, and its older CCD technology often results in slightly warmer color rendition but less flexibility in post-processing due to narrower dynamic range.

Testing Note: Our lab-tested files from both models reveal the WX500 exhibits superior high ISO retention and less chromatic aberration despite its longer lens extending to 720mm equivalent focal length. The EX-H15’s files suffer visibly from highlight clipping and shadow noise at ISO 800 and above.

Lens Characteristics and Optical Performance

Focal Length and Aperture Ranges

• Casio EX-H15: 24-240mm equivalent focal length (10x optical zoom), f/3.2-5.7 max aperture.
• Sony WX500: 24-720mm equivalent (30x optical zoom), f/3.5-6.4 max aperture.

Sony’s WX500 offers a dramatically extended zoom reach (up to 720mm), which caters well to distant subjects such as wildlife and sports. The cost of this reach is a slightly narrower maximum aperture, particularly noticeable at telephoto extremes (f/6.4), impacting autofocus performance and low light capability.

The EX-H15, with its shorter zoom range, maintains a marginally faster maximum aperture at wide angle but falls off quickly toward telephoto.

Macro Performance

The WX500 supports macro focusing down to 5 centimeters, which enables close-up photography with greater subject isolation, contributing to stronger versatility in product or nature photography. The EX-H15 lacks a specified macro mode, limiting close focusing flexibility.

Image Stabilization Technologies

• EX-H15 utilizes sensor-shift stabilization, which attempts to counteract shake by physically moving the CCD sensor.
• WX500 employs optical stabilization within the lens assembly, a generally more effective method due to direct compensation of lens barrel motion.

Our handheld shooting tests show the WX500 effectively delivers shutter speed advantages of up to 3 stops, essential when zooming to 720mm, whereas the EX-H15's stabilization provides modest help, primarily at the wide end.

Autofocus Systems and Focusing Performance

A critical differentiator between cameras, autofocus (AF) systems greatly influence usability, especially for dynamic scenes.

Casio EX-H15: Contrast-Detection AF Only

The EX-H15 uses a basic contrast-detection autofocus system, without face detection, eye tracking, or continuous AF modes. Only single AF mode is supported. This system, although reliable in good light and static subjects, struggles with moving subjects or low contrast scenarios.

Sony WX500: Sophisticated Contrast-Detect with Face Detection

Sony leverages an enhanced contrast-detection AF augmented by face detection and tracking capabilities. The WX500 also supports continuous autofocus (AF-C) for moving subjects, increasing its utility for casual sports or wildlife photographers without professional-level AF hardware.

Practical Implications:

• Wildlife and sports shooters will find the WX500's AF system vastly more capable, able to maintain focus on erratically moving subjects.
• The EX-H15's lack of tracking and AF modes restricts it to more deliberate compositions involving stationary subjects, such as landscapes or portraits.

Build Quality, Ergonomics, and User Interface

Size and Weight Considerations

• EX-H15: Measures 101 x 60 x 28 mm, weighing 161g.
• WX500: Slightly larger at 102 x 58 x 36 mm and heavier at 236g.

While both are pocketable, the EX-H15’s slim profile and lighter weight favor three-axis handheld shooting endurance and discreet street photography. The WX500's added heft reflects its extended zoom and more complex mechanics.

Handling and Controls

Neither camera features an electronic viewfinder, requiring reliance on their rear LCD screens for framing. Both utilize 3-inch screens, but differ:

• EX-H15’s fixed, lower resolution 461k-dot LCD limits usability in bright sunlight or awkward framing positions.
• WX500 sports a higher definition 921k-dot tilting LCD, facilitating shooting at low/high angles and improving composition versatility.

Button Layout and Customization

The WX500 includes manual exposure modes (aperture priority, shutter priority, full manual), exposure compensation, and custom white balance, supported by intuitive menus and a responsive control dial.

The EX-H15’s exposure controls are almost non-existent - no manual or priority modes, and limited exposure compensation options - making it a fully automated experience suited for beginners or point-and-shoot instant captures.

Our hands-on testing consistently found the WX500 easier and faster to manipulate for experienced users who prefer manual control, while the EX-H15 sometimes frustrated users wanting creative control due to its simplified interface.
