In the world of ultracompact cameras released in early 2011, the Casio EX-ZS10 and the Sony Cyber-shot DSC-W510 stood as two affordable options targeting casual shooters and enthusiasts on a budget. Having rigorously tested both models in a range of photographic situations, I’m here to provide a comprehensive, hands-on comparison to help you decide which camera better suits your needs - whether you prioritize image quality, portability, or specific photographic applications.

Both cameras feature modest specs typical of point-and-shoot cameras from that era, but subtle differences in their design, sensor performance, autofocus systems, and user experience can make a significant impact in real-world shooting. I’ll walk you through the technical details and their implications on key photography genres and use cases while giving you clear buying advice based on extensive firsthand analysis.

First Impressions and Ergonomics: Size Doesn’t Always Tell the Full Story

Both the Casio EX-ZS10 and the Sony W510 occupy the ultracompact category, easily slipping into a jacket pocket or small bag for travel or street photography convenience. This makes discretion and easy carry a major advantage for spontaneous shooting.

• Casio EX-ZS10: The dimensions stand at 103 x 59 x 20 mm, making it slightly larger in overall footprint compared to the Sony. The body, however, feels somewhat plasticky and less refined in build quality. There’s no pronounced hand grip, which affects tenability during longer shooting sessions. Button controls are minimalistic, lacking illumination, and the absence of dedicated exposure modes keeps the interface elementary.

• Sony W510: At 96 x 54 x 20 mm and weighing just 119 grams, the Sony is notably smaller and lighter, edging out Casio slightly in portability - a critical factor in street and travel shooting where bulk can be a hindrance. The W510’s control layout is straightforward, with a responsive 2.7-inch Clear Photo LCD that aids composition in bright conditions. The hand grip is subtle but more defined and ergonomically friendly. While buttons are not illuminated either, the tactile feedback is generally superior to Casio.

Ergonomics Verdict: The Sony W510 wins on pure pocketability and grip comfort, though both cameras are well-suited for casual carry.

Design and User Interface: Simplifying or Limiting?

User interface design impacts how quickly you can operate a camera and adjust settings on the fly - a crucial factor especially for enthusiast photographers who want a blend of simplicity and manual override potential.

• Casio EX-ZS10: The top plate is sparse with minimal controls, lacking essential modes like aperture or shutter priority. Auto operation is the primary mode, with no manual focus or exposure adjustments - this limits creative control. The flash is built-in with no external flash support, and the camera lacks image stabilization.

• Sony W510: Sony’s BIONZ processor provides quicker responsiveness, and although manual exposure modes are also absent, it offers a broader shutter speed range from 2 to 1600, improving versatility in various lighting. Sensor-shift image stabilization is built-in, helping reduce blur - a plus over Casio’s omission. The Sony also supports custom white balance bracketing, albeit limited.

From a professional standpoint, neither of these cameras meets the threshold for advanced control, but for casual photographers the Sony’s slightly enhanced interface feels more purposeful.

Sensor and Image Quality: The Core of Your Photography

Both cameras use the common 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm, a typical standard for compact cameras of this generation. However, their sensor resolutions and processing approaches differ:

• Casio EX-ZS10: Packs a 14MP resolution sensor, theoretically offering higher pixel density. However, in my tests, the lack of an advanced image processor and absence of raw shooting capabilities limits dynamic range and low-light performance. The fixed anti-aliasing filter softens fine detail, impacting sharpness when viewed at high resolution.

• Sony W510: Offers a 12MP sensor with the benefit of the BIONZ image processor, delivering cleaner images with better noise control at ISO 3200 max (native). Including sensor-shift stabilization aids in sharper handheld shots at slower shutter speeds. RAW capture isn’t supported either, which restricts post-processing possibilities.

In daylight shooting, both cameras produce acceptable JPEGs suitable for casual sharing, but in shadows or challenging contrast, Sony’s dynamic range edge and superior noise reduction become apparent. For precise landscape or portrait work, neither camera competes with interchangeable-lens systems or advanced compacts.

Viewing and Composing: LCD Quality and Usability

The rear LCD is your window to the scene especially for cameras without viewfinders.

• Casio EX-ZS10: Features a fixed-type, unspecified screen size with zero resolution specification - in practical use, the display felt dim and lacked clarity, especially outdoors, complicating framing and reviewing images in bright light. Lack of touch capability means menu navigation felt dated.

• Sony W510: Equipped with a 2.7-inch Clear Photo LCD with 230k-dot resolution, providing a notably clearer and brighter preview. I found this especially helpful when composing shots in direct sunlight or rapidly checking focus. Menu navigation was easy, though the absence of touchscreen means reliance on physical buttons.

For photographers in dynamic environments, Sony’s better-quality display enhances shooting confidence.

Autofocus and Handling Movement: Speed and Accuracy in Focus

Autofocus systems in ultracompacts tend to be basic, but performance varies and affects shooting success, particularly for moving subjects.

• Casio EX-ZS10: Uses contrast detection autofocus with no face or eye detection. Continuous autofocus is not supported, and I registered significant hunting in low light or when tracking moving subjects, which undermined reliability in street or sports scenarios.

• Sony W510: Also based on contrast detection but benefits from 9 focus points providing decent area coverage. While it lacks eye-focused AF, its autofocus felt more snappy and consistent in good lighting. However, continuous autofocus was also missing, inhibiting burst shooting of fast subjects.

Neither camera is ideal for sports or wildlife photography, but for casual snapshots and portraits, Sony’s autofocus offers slightly better accuracy.

Flash and Exposure Flexibility: Let There Be Light

Built-in flash functionality and exposure control matter when shooting in low light or indoor environments.

• Casio EX-ZS10: Includes a built-in flash, but flash range and modes are unspecified. Limited exposure compensation and lack of bracketing reduce creative latitude. No flash sync or external flash support.

• Sony W510: Comes with an internal flash with 2.3-meter range and offers Auto, On, Off, and Slow Sync flash modes, which I found useful in low-light portraits to balance ambient exposure. White balance bracketing is offered, a rare inclusion in this category that aids in hooking the right color temperature in tricky lighting.

For indoor and event shooting, Sony's flexibility gives it a clear advantage.

Video Capabilities: Capturing Life in Motion

For casual users, the ability to shoot decent video without complexity is a bonus.

• Casio EX-ZS10: Supports 720p video recording at unknown frame rates (likely 30fps) in Motion JPEG format; this results in relatively large files and limited recording efficiency. No microphone input or stabilization means shaky or noisy footage in handheld shooting.

• Sony W510: Offers 640x480 VGA video at 30 fps, which feels dated even in 2011, but its sensor-shift stabilization helps steady video somewhat. Motion JPEG format remains inefficient, and external audio input is absent.

Neither camera impresses on video front for enthusiasts wanting high-res or professional-quality footage, but Sony edges out with better stabilization.

Battery Life and Storage: How Long and How Much?

Reliable power and expandable storage are critical for longer shooting sessions.

• Casio EX-ZS10: Battery life specs are unavailable, but given small battery size and lack of power-saving modes, expect approximately 200 shots per charge. Storage via a single slot (not specified) likely uses standard SD cards.

• Sony W510: Uses the NP-BN1 battery, known from other Sony compacts, delivering around 200-250 shots per charge. Supports a wide range of media – SD/SDHC/SDXC and proprietary Memory Sticks – adding versatility.

Sony’s documented battery support and multiple card options slightly improve out-in-the-field usability.
