Sony RX10 IV vs Sony W800: A Deep Dive into Two Very Different Cameras

When comparing cameras, it's easy to get caught up in specs and marketing buzzwords. But from 15+ years of hands-on experience testing cameras of all types, I know the real questions buyers ask are: How do these cameras perform in everyday photography? Which one matches my needs and wallet? Today, we're peeling back layers on two Sony models - the premium Sony Cyber-shot DSC-RX10 IV (RX10 IV), a large sensor superzoom bridge camera, and the entry-level Sony Cyber-shot DSC-W800 (W800), a budget-friendly compact. Though they share a brand name, these cameras serve vastly different purposes.

I’ve spent extensive time evaluating both, pushing their autofocus systems, image quality, video, and ergonomics to determine what each excels at - and where compromises show. I’ll guide you through all major photographic disciplines, real-world use cases, and technical analyses, so you can confidently decide which camera belongs in your kit or if neither is quite right.

First Impressions: Size, Handling, and Build

Grabbing the RX10 IV and the W800 side-by-side immediately underscores their divergent design philosophies.

The RX10 IV is an SLR-style bridge camera with a substantial body weighing about 1095g. Its hefty grip, sizeable lens barrel, and rugged build with weather resistance signal a camera built for serious handheld shooting in diverse environments. The physical dimensions (133x94x145 mm) give it a commanding presence and plenty of room for extensive physical controls.

Contrast that with the W800, a tiny compact measuring just 97x55x21 mm and tipping the scales at a mere 125g. This ultra-portable design doesn’t offer weather sealing and focuses on lightweight convenience over ruggedness or tactile control.

My takeaway: If you want a camera to carry all day without fatigue, the W800 shines. But if you crave extensive handling options and a durable body, the RX10 IV aligns with professional enthusiast expectations.

Control Layout and User Interface: Fast Access or Simplified?

Looking down from above, the control differences are stark:

• RX10 IV: Numerous physical buttons, dials, and a top LCD display for quick setting checks. The extensive control scheme supports advanced features like aperture/shutter priority, manual exposure, and custom white balance with ease. A large electronic viewfinder (EVF) facilitates traditional framing, especially in bright conditions.

• W800: Minimal buttons and only a fixed 2.7-inch LCD screen without touchscreen capability. No EVF to speak of. Exposure modes are automated, with no shutter/aperture priority or manual modes.

The RX10 IV’s thoughtfully designed controls respond instantly and help craft shots in dynamic scenarios. The W800 leans toward absolute simplicity; perfect if you prefer point-and-shoot ease with minimal fuss.

Sensor and Image Quality: The Heart of the Matter

Here’s where the cameras part ways most dramatically:

The RX10 IV uses a significantly larger 1-inch BSI-CMOS sensor, yielding better low light performance, dynamic range, and color depth. Its back-illuminated design improves light gathering.

The W800’s smaller 1/2.3” CCD sensor - common in inexpensive compacts - lags in performance, especially at higher ISO settings where noise and detail loss become prominent. It does provide a comparable megapixel count, but without raw file support, post-processing flexibility is limited.

Real-World Image Insights:

• Portraits: The RX10 IV’s sensor and faster lens (f/2.4-4) allow pleasant background blur (bokeh) and nuanced skin tone rendering. Eye and animal eye autofocus further refine portrait sharpness. The W800 struggles to isolate subjects, resulting in flatter, less dimensional portraits.

• Landscape: The RX10 IV’s sensor dynamic range and resolution capture detail in shadows and highlights superbly across wide scenes. Weather sealing protects during outdoor shoots. The W800’s images often show limited tonal range, and weather sealing is absent.

• Low-light and Night: The RX10 IV shines with low noise at ISO 3200 and above, while the W800’s usable ISO tops out at 800 with noticeable grain and detail loss.

Autofocus: Precision and Speed Matter

Both cameras focus differently due to their tech and sensor sizes:

The RX10 IV’s advanced autofocus supports rapid, accurate eye detection and animal eye AF, coupled with continuous AF and impressive tracking for moving subjects (up to 24 fps burst). This transforms wildlife and sports shooting, especially in challenging light.

The W800 is more basic, with slow, contrast-only AF and no manual focus; it’s built for static scenes and slow-paced shooting. You’ll notice hunting focus and less reliability tracking heads or small fast-moving subjects.

Lens Versatility: Zoom Reach and Aperture

The RX10 IV’s incredible 25x zoom range covers wide-angle to super-telephoto, making it highly adaptable. Its fast aperture across the focal range aids depth of field control and low-light shooting. You can focus down to 3cm from the lens for semi-macro shots.

The W800’s 5x zoom with a narrow aperture range restricts versatility, especially in low light or reaching distant subjects.

Ergonomics and Display: Framing and Reviewing

Both cameras employ 3-inch screens, but their quality and usability vary:

• RX10 IV: A tilting touchscreen with 1.44M dot resolution provides bright, detailed live view and easy touch focus/select features. An electronic viewfinder (with 2.36M dots) offers eye-level framing and better visibility in bright environments.

• W800: Fixed 2.7-inch LCD with low resolution (230k dots) and no touchscreen, making menu navigation and focusing adjustments slower and less precise. No EVF means eye-level composition is out.

In hands-on shooting, the RX10 IV’s interface feels professional and fluid, the W800 caters to casual shooters content with simple controls.

Shooting Performance: Speed, Burst, and Buffer

For sports and wildlife photographers, the RX10 IV’s 24 fps burst rate with AF tracking is a serious advantage, capturing fleeting moments with reliability.

The W800’s single fps burst rate and slower shutter mean it’s suited mostly for still subjects or casual snapshots.

Video Capabilities: High-Definition or Basic Clips

The RX10 IV doubles as a powerful 4K video camera suitable for professional use, with clean HDMI output and microphone/headphone jacks for audio monitoring. Its lens-based stabilization helps keep footage steady.

The W800’s video is limited to basic 720p clips without manual controls or audio inputs, more for casual family videos than serious content creation.

Battery Life and Storage

The more power-hungry RX10 IV delivers solid battery life thanks to a large NP-FW50 pack, suited for all-day shooting. The W800’s battery life is modest, consistent with its entry-level design.

Connectivity and Extra Features

RX10 IV offers robust wireless features for remote control and wireless file transfers. Its weather resistance broadens shooting possibilities in inclement conditions.
