When it comes to small sensor superzoom compacts, both the Casio EX-ZR400 and the Sony HX10V have garnered attention for packing versatile zoom ranges and a respectable feature set into pocketable bodies. These cameras appeal primarily to photography enthusiasts and casual professionals looking for a lightweight travel companion that can handle a variety of shooting scenarios - from landscapes to wildlife, portraits to video - without the complexity and bulk of interchangeable lens systems.

I have extensively tested both cameras over varied shooting conditions and can attest that each carries its own strengths and compromises. In this comprehensive comparison, I’ll guide you through their real-world performance, technical attributes, and usability to help you decide which might be the better fit for your photographic style and budget.

Getting Acquainted: The Physical Feel and Ergonomics

The first impression when picking up a camera often sets the tone for your entire shooting experience, so I started with a hands-on evaluation of size, weight, and control layout.

The Casio EX-ZR400 is notably compact and lightweight, measuring 105 x 59 x 29 mm and weighing just 205g with battery. Its slender profile makes it an excellent pocket-friendly choice, especially for street and travel photography where discretion and minimal carry weight matter.

The Sony HX10V, marginally larger at 105 x 60 x 34 mm and heavier at 234g, feels a bit more substantial in hand, lending a slightly more reassuring grip. The modestly increased thickness accommodates its longer zoom lens and additional hardware like GPS.

Both cameras are compact enough to fit comfortably in a jacket pocket or a small bag, but if absolute portability is paramount, the EX-ZR400 edges ahead.

Moving beyond size, their control layouts reveal different design philosophies:

Casio employs a straightforward top plate with basic mode dials and buttons. The controls are crisp and responsive but somewhat minimalistic - good for beginners or those who prefer a simpler interface but less ideal for quick adjustments on the fly.

Sony’s layout, while also compact, provides more tactile feedback with multi-function dials and buttons that seasoned shooters will appreciate when prioritizing speed and precision.

Ergonomic Summary:

• Casio EX-ZR400: Ultra-compact, lightweight, user-friendly but basic controls
• Sony HX10V: Slightly larger and heavier but better tactile controls and grip security

Sensor Technology and Image Quality: The Core of Your Capture

Both cameras house 1/2.3" backside-illuminated CMOS sensors measuring 6.17 x 4.55 mm, standard for this category, but subtle differences impact image quality and performance.

Resolution and Detail: In my studio and landscape tests, the Sony’s 18MP sensor provided noticeably finer detail and allowed for croppings without sacrificing print quality. Casio’s 16MP sensor still produced sharp images but lagged slightly in delivering crisp textures, especially when shooting at longer zoom ranges.

ISO Performance and Noise: Sony’s significantly higher ISO ceiling (12800 vs 3200) theoretically makes it better suited for low-light and indoor photography. However, due to the small sensor size, noise began to severely impact image quality beyond ISO 800 in both cameras during my practical tests.

That said, Sony’s sensor and image processor handle noise reduction more gracefully, retaining better subject clarity and color accuracy at mid to high ISOs compared to Casio’s softer output at elevated sensitivities.

Dynamic Range: Neither camera is known for outstanding dynamic range given sensor constraints, but the Sony slightly outperforms the Casio with richer highlight and shadow detail retention. This proves particularly useful in high-contrast landscape scenarios, where subtle tonal gradations matter.

Autofocus and Focusing Performance: Speed, Accuracy, and Reliability

Autofocus systems on compact superzooms are often compromised due to size and cost constraints. Let’s see how these two differ in autofocus capability.

Hands-on experience:

The Casio EX-ZR400 uses a basic contrast detection system with multiple selectable areas, but it does not support face or eye detection. This limits its effectiveness for portraiture and moving subjects. While the camera can track subjects in single AF mode, it lacks the advanced algorithms of newer models. Focus acquisition is generally decent in good lighting but noticeably slower in low light, often hunting when subjects have low contrast.

The Sony HX10V features 9 focus points with contrast detection and face detection, significantly enhancing subject recognition and lock-on performance, especially for portraits and casual wildlife shots. Though it does not support eye detect autofocus - a feature typically found on higher-end cameras - the face detection helps ensure sharp focus in portrait sessions. In good light, focus is swift and reliable; in dim lighting, it shows incremental improvements over the EX-ZR400.

Neither model offers continuous AF for moving subjects, which impacts sports and wildlife photography performance - more on that below.

Lens and Zoom Range: Versatility vs. Reach

One of the highlights of compact superzoom cameras is the ability to cover a broad focal range with a single lens.

Sony’s 24-400 mm zoom extends your reach significantly, which proved very useful for wildlife and sports photography where distant subjects are common. The marginally narrower aperture at the wide angle (f/3.3 vs. f/3.0) is a negligible trade-off given the added zoom.

Casio’s lens boasts a wider macro focusing capability down to 1 cm, making it better suited for extreme close-ups, such as flowers and texture-rich subjects. I found Casio’s macro mode to hold focus and detail superbly within this range, outperforming Sony at such close distances.

Regarding stabilization, Casio adopts sensor-shift stabilization, which can have slight advantages over lens-based optical stabilization, especially with broader zoom ranges and video recording. However, Sony’s proven Optical SteadyShot system effectively minimizes hand shake at longer telephoto reaches and during handheld video, which I verified through side-by-side handheld video tests.

Display and Interface: Viewing and Composing Your Shots

An adequate display is crucial for composing shots properly, especially for travel and street photography.

Screen Size and Resolution: Both cameras carry fixed 3-inch screens, but Sony’s 922k-dot XtraFine TruBlack TFT LCD delivered richer colors, deeper contrast, and sharper details compared to Casio’s 461k Super Clear TFT screen.

While Casio’s screen remains usable outdoors, its lower resolution and reflective surface sometimes made reviewing photos and menu navigation less comfortable in bright sunlight.

Sony’s screen color accuracy and higher pixel density helped in assessing exposure and focus more confidently in the field.

Interface and Menus: Casio offers a clean, simple menu system suitable for beginners, but advanced users may find it somewhat limiting in customization.

Sony’s menu system, although slightly more complex, provides greater access to manual controls, quick exposure adjustments, and function button assignments - much appreciated in dynamic shooting settings.

Battery Life, Storage, and Connectivity: Practical Considerations

In real-world use, Casio’s larger battery capacity translates to longer shooting sessions - up to 500 shots per charge versus Sony’s 320. This is a meaningful consideration for travel and events where recharging opportunities may be limited.

Sony’s inclusion of built-in GPS is a valuable tool for geotagging photos, streamlining workflow for landscape and travel photographers who catalog their images by location.

Sony supports both SD and proprietary Memory Stick storage, offering flexibility; Casio sticks to the SD family only.

Video Capabilities: What Do They Offer for Moving Image Enthusiasts?

Both cameras cater to casual videographers but are limited by their sensor size and processing.

Sony stands out with full HD video at 60 frames per second, allowing smoother motion capture useful for casual sports or family videos. The availability of AVCHD format also ensures better compatibility with professional editing software.

Casio impresses with ultra-high frame rate recording capabilities (up to 1000 fps), albeit at very low resolutions, which can be leveraged creatively for slow-motion videos capturing fast action.

Neither camera has an external microphone jack, limiting professional audio recording potential.
