Casio EX-H20G vs Sony Cyber-shot DSC-W730: A Hands-On Comparison for Enthusiast Photographers

Choosing the right compact camera is often about balancing portability, image quality, features, and price - especially when considering models like the Casio EX-H20G and Sony Cyber-shot DSC-W730. Both are small-sensor compacts pitched at casual shooters looking for easy versatility without the bulk of interchangeable lenses. But behind their seemingly similar specs lies subtle yet impactful differences that can shape your photographic experience.

Having personally put these cameras through comprehensive testing across multiple photography styles - portrait, landscape, wildlife, macro, and more - I’ll take you through a detailed, side-by-side comparison grounded in real-world use and technical analysis. Whether you’re a keen enthusiast wanting a capable pocketable backup or a beginner looking for a step up from your phone, this guide will help you make the best choice.

Getting to Know the Contenders: Physical Size and Handling

Both cameras fall under the small sensor compact category, designed for portability. The Casio EX-H20G sports a slightly larger footprint than the Sony W730, owing to its longer zoom lens and bigger battery, but both remain comfortably pocketable.

• Casio EX-H20G: Measures 103 x 68 x 29 mm, weighs 216 g.
• Sony W730: More compact at 93 x 52 x 22 mm, lighter at 122 g.

From ergonomic testing, the EX-H20G’s thicker body offers a reassuring grip, especially when shooting at telephoto lengths. Buttons are well-spaced and feel tactile under the fingers, which is helpful for quick setting adjustments. In contrast, the Sony W730 is sleeker and lighter, making it ideal for travelers or street photographers prioritizing discretion and reduced pocket weight. However, the smaller size does trade off some handling comfort during extended shooting sessions or with larger hands.

Takeaway: If you value a stable, substantial feel and longer zoom reach, Casio’s size works in your favor. For ultimate portability without a big compromise on features, the Sony W730’s compactness is compelling.

Design and Control Layout: Intuitive or Compromised?

Control layout greatly influences shooting speed and workflow efficiency. Let’s take a look at the cameras’ top plates and button arrangements:

The Casio EX-H20G features a classic compact layout with a dedicated zoom rocker encircling the shutter button and a mode dial that’s easy to reach even while holding. The inclusion of a physical shooting mode dial is a big plus, letting you switch between Program, Auto, and Scene modes instantly - a convenience that makes sense for enthusiasts who crave creative control.

Sony’s W730, in contrast, strips down to essential buttons and eschews a mode dial. It relies on menu navigation for scene modes and adjustments, which can slow operation in dynamic shooting scenarios. The touchscreen, however, adds a layer of directness via touch-to-focus and settings access - although it’s smaller (2.7 inches vs Casio’s 3 inches) and has lower resolution.

Buttons on the Sony feel adequately clicky but smaller; the Casio’s are more generously sized and comfortable for quick tactile access, from my hands-on experience.

In summary:

• Casio EX-H20G: Physical controls and mode dial favor quick, confident shooting.
• Sony W730: Touchscreen offers flexibility but physical controls are minimalist and can slow rapid changes.

Sensor Technology and Image Quality Showdown

Both cameras use a 1/2.3" CCD sensor measuring 6.17 x 4.55 mm, typical for this class, but with different native resolutions:

• Casio EX-H20G: 14 megapixels (4320x3240)
• Sony W730: 16 megapixels (4608x3456)

The additional megapixels on the Sony offer a slight edge in terms of resolution potential for larger prints or cropping flexibility. Yet, sensor size being identical means physics limits their dynamic range and noise performance similarly.

In lab tests and field shooting under well-controlled light, both cameras deliver crisp results at base ISO with minimal noise, thanks to the CCD sensors known for natural color reproduction but weaker low light handling compared to modern CMOS.

When pushing ISO beyond 400, image degradation becomes apparent - grain and loss of detail increase noticeably. Between the two, the Sony slightly outperforms Casio in noise suppression and color consistency at mid ISOs, likely due to incremental sensor and processing advancements made three years after the Casio’s release.

Both cameras lack raw file support, meaning you’re limited to JPEG output, which restricts post-processing latitude.

Practical Note: For daylight portraits, landscapes, and travel photos, either camera suffices, but for demanding low light or shadow recovery, expect compromises.

LCD Screen and Interface: Clarity and Usability in Real Life

The rear LCD is your window to composing and reviewing images:

• Casio EX-H20G: 3.0-inch fixed screen with 461k-dot resolution.
• Sony W730: 2.7-inch TFT LCD touchscreen, 230k dots.

From usage, Casio’s larger, higher-resolution screen provides better clarity outdoors and more accurate framing. Sony’s touchscreen support is handy for selecting AF points directly, but the lower pixel density can make finer details harder to discern in bright sunlight.

Neither camera offers an electronic viewfinder, requiring eye-level shooting techniques or reliance on the LCD under all conditions - something to keep in mind if you prefer shooting with a viewfinder.

Autofocus and Shooting Speed: Who’s Quicker on the Draw?

Despite their compact form, autofocus performance varies notably between these two:

• Casio: Contrast-detection AF only, without face or tracking assists. Autofocus is single-shot; no continuous AF or tracking. Focus speed is moderate, sometimes hesitant in low contrast or dim environments.

• Sony: Contrast-detection with face detection and limited tracking support. You can touch the screen to set focus points. Autofocus is single-shot with tracking capabilities. From my testing, Sony locks focus faster on faces, especially in good lighting.

Continuous shooting speeds are slow in both:

• Casio: No continuous burst specified, effectively single-shot mode.
• Sony: 1 fps continuous shooting, which is very basic and unsuitable for action sequences.

For wildlife or sports, neither camera is designed to deliver high tracking accuracy or fast burst rates. If rapid focus or frame rates are priorities, these compacts lag behind enthusiast mirrorless or bridge cameras.

Lens and Zoom: Reach vs. Usability

Both cameras feature fixed lenses with equivalent zoom multipliers but differ in focal length:

Casio’s slightly longer reach makes it better suited to distant subjects like casual wildlife or sports from afar. The wider aperture maximums on both lenses are fairly slow, limiting shallow depth of field potential - expected in compact zoom lenses.

Sony’s closer macro focusing distance (5 cm) gives it a small edge for close-up work, letting you capture more detail on flowers or small objects within the frame. Both cameras leverage sensor-shift (Casio) or optical (Sony) image stabilization effectively, helping mitigate blur during telephoto shots.

Build Quality and Weather Resistance: Prepared for the Roads

Both cameras are consumer-grade compacts without weather sealing or ruggedized bodies. Neither is waterproof, dustproof, shockproof, crushproof, or freezeproof.

While the EX-H20G feels tankier in hand due to its size and weight, both should be protected from moisture and impact to ensure longevity.

Battery Life and Storage: Shooting Endurance

Sony’s W730 reports approximate 240 shots per full charge using its NP-BN battery, a modest figure that means carrying a spare battery or charger is wise for extended trips.

The Casio EX-H20G's battery life isn’t officially specified, but the larger NP-90 pack typically delivers moderate stamina in this class.

Both cameras accept SD/SDHC/SDXC cards, but Sony also supports Memory Stick options - an advantage for users with legacy accessories.

Connectivity and Extras: Modern Conveniences

The Casio offers built-in GPS for geotagging photos and Eye-Fi card compatibility for basic wireless image transfer. Sony W730 lacks wireless connectivity altogether.

Sony supports touchscreen AF and menu controls, offering a modern interaction style missing on the Casio.

Neither camera sports microphone or headphone jacks for video audio input or monitoring.

Video Performance: Modest, But Functional

Both record HD video at 1280 x 720 at 30 fps:

• Casio: H.264 format, no manual exposure controls in video mode.
• Sony: MPEG-4 and AVCHD formats, no advanced video features.

Neither camera includes in-body video stabilization beyond the still-image sensor shifts, nor do they provide manual focus or exposure controls during recording.

These are basic recorder tools - fine for casual clips but not suited to videographers seeking creative control.

Real World in Action: Sample Image Gallery

I tested both cameras across multiple shooting scenarios to gauge practical output quality:
