Sony RX10 IV vs Sony W690: A Deep Dive Into Two Distinct Cameras

When Sony launched the Cyber-shot DSC-RX10 IV and Cyber-shot DSC-W690, they aimed at vastly different users and photographic needs. Over the years, I’ve tested thousands of cameras across photography genres, and these two models represent opposite ends of the spectrum - from a high-performance large sensor superzoom bridge camera to an ultra-affordable, compact small sensor point-and-shoot. In this detailed review, I’ll unpack their technical specifications, real-world usability, and image quality across various photography disciplines to help you decide which makes sense for your photography style and budget.

Size, Build, and Ergonomics: How They Feel in Your Hands

A camera’s physical design impacts everything from shooting comfort to portability. I spent hands-on time with both, measuring and evaluating their ergonomics.

Sony RX10 IV: This bridge-style camera weighs 1095g and measures 133 x 94 x 145 mm. It features a robust grip and SLR-like handling with manual dials and dedicated buttons for direct access to settings. Weather resistance adds to its durability, making it suitable for fieldwork in diverse conditions. The articulating 3-inch touchscreen adds flexibility for creative angles and quick menu navigation.

Sony W690: Compactness defines the W690, weighing only 142g and sized 94 x 56 x 22 mm - pocketable and ultra-light. Its slim body is great for discreet street or casual travel shots, but lacks a viewfinder and any manual control dials. The fixed 3-inch screen is not touch-enabled, limiting interaction speed compared to the RX10 IV.

The RX10 IV’s heft and grip convey a professional feel you’d expect in heavier superzoom cameras, while the W690’s ultra-compact footprint suits casual users or as a backup camera.

Design and Control Layout: Intuitive or Minimalist?

Visualizing how controls are laid out in top-down views can clarify usability during fast-paced shooting.

Sony RX10 IV sports a thoughtful combination of classic shutter speed dial, aperture ring on the lens barrel, programmable function buttons, and a mode dial - offering complete manual control on the fly. The rear hosts a well-designed joystick for AF point selection, along with a customizable control wheel. This camera clearly targets enthusiast and professional users who want quick tactile control without delving into menus.

In contrast, the W690 keeps things simple: a zoom rocker, shutter button, and minimal mode selection squared with casual shooting. The absence of manual exposure modes or dedicated AF point controls limits creative control but keeps shooting easy for beginners.

Sensor Technology and Image Quality: Large vs Small Matters

Arguably the heart of any camera is its sensor - the bigger it is, the better the potential for image quality, dynamic range, and low-light capability. Here’s a side-by-side breakdown.

The RX10 IV utilizes a 1-inch back-illuminated CMOS sensor designed for excellent light gathering and low noise across a broad ISO spectrum. Its 20 MP resolution is ideal for large prints and cropping flexibility.

The W690’s smaller 1/2.3-inch CCD sensor sacrifices sensitivity and dynamic range, reflected in its limited ISO ceiling and lack of RAW output. Images tend to have lower detail and more noise in low light.

Real-world Experience: Testing both under controlled conditions, I observed the RX10 IV produce crisp details, smooth noise control up to ISO 3200, and punchy colors. The W690 images look acceptable for casual sharing but falter in shadows and low light.

Viewing and Interface: Screen and Viewfinder Quality

Comfort and accuracy in framing your shots depend on the camera’s display tech and electronic viewfinder (EVF).

• RX10 IV: Features a 3-inch tilting touchscreen at 1.44 million dots resolution paired with a bright 2.36 million-dot OLED EVF offering 100% coverage and 0.7x magnification for precise composition - especially helpful in bright outdoor conditions or fast action.

• W690: Has a fixed non-touch 3-inch LCD with only 230k dots resolution and no viewfinder. This screen is dimmer and less detailed, making it harder to verify focus or review images outdoors.

The RX10 IV’s dual display system supports varied shooting styles with rich feedback and control access. Meanwhile, the W690 streamlines simplicity at the expense of image preview accuracy.

Autofocus Systems: Precision and Speed Under Pressure

Autofocus technology determines how well a camera tracks moving subjects and quickly locks focus - essential for wildlife, sports, and street photography.

The RX10 IV leverages a hybrid AF system with 315 points, enabling rapid focus acquisition and reliable continuous tracking at up to 24 fps - outstanding for capturing fast subjects like birds or athletes. Its animal eye AF enhances wildlife portrait sharpness.

The W690’s basic contrast-detection AF offers modest accuracy and speed, suitable for static or slow-moving subjects. It also lacks continuous AF and burst modes.

My testing: The RX10 IV excelled in tracking erratic subjects and maintaining focus during rapid panning. The W690 occasionally hunted for focus under lower contrast scenes and struggled with moving targets.

Lens and Zoom Capabilities: Versatility and Reach

Both have fixed zoom lenses but differ drastically in focal length range, aperture, and zoom quality.

The RX10 IV’s bright zoom lens is a highlight - sharp from edge to edge across the focal length, with a wide F2.4 aperture supporting shallow depth of field effects and better low-light capture. The 600mm reach combined with image stabilization makes it adept at wildlife and sports telephoto shooting.

The W690 offers a smaller 10x zoom and slower aperture, limiting low-light versatility and background blur. Its macro mode focusing down to 5 cm still allows casual close-ups but lacks the precision or magnification of higher-end cameras.

Burst Shooting and Shutter Performance

Capturing fast action demands rapid shutter speeds and high burst rates.

In my shootouts, the RX10 IV’s electronic shutter allowed ultra-fast speeds and silent operation - crucial in quiet environments like weddings or wildlife settings. Additionally, its 24 fps burst captured fluid sequences, ideal for birds in flight or sports.

The W690’s limited 1 fps burst rate means it’s unsuitable for action photography.

Video Features: Quality and Flexibility for Filmmakers

Evaluating video capability is increasingly important as cameras become hybrid devices.

The RX10 IV stands out with professional-grade 4K video, clean HDMI output, and audio input/output jacks - features that videographers will appreciate for high-quality production and monitoring. Its lens covers a wide to super-telephoto range, letting you zoom dynamically without swapping lenses.

The W690’s video caps at 720p, adequate for casual clips but limited for serious video work.

Battery Life and Storage: Endurance for Long Days

Battery endurance and storage flexibility influence field shooting.

While neither camera offers dual card slots (a pro feature for backup), the RX10 IV’s longer battery life supports longer shoots without interruption.

Image Samples and Real-World Output Quality

Nothing replaces a hands-on look at actual images caught with each camera under diverse conditions.
