Sony RX10 II vs Sony W620: A Detailed Comparison for Every Photographer’s Needs

Choosing the right camera is a balancing act between your photography ambitions, budget, and practical needs. In this article, I’ll provide an expert, hands-on comparison of two very different Sony cameras - the Sony RX10 II bridge camera and the Sony W620 compact point-and-shoot. Both have their merits, but target distinctly different users.

With over 15 years of extensive testing behind me, I’ve evaluated both cameras’ core strengths across photography disciplines, alongside their tech specs, ergonomics, and real-world usability. Whether you’re a pro seeking a versatile walk-around superzoom or a casual shooter wanting simplicity and convenience, you’ll gain clear insights to make an informed purchasing decision.

First Impressions: Size, Handling, and Build Quality

The RX10 II and W620 could hardly be more different in size and build. The RX10 II is a large sensor superzoom bridge camera with an SLR-style body, while the W620 is a compact, lightweight small sensor point-and-shoot.

• RX10 II measures 129 x 88 x 102 mm and weighs a substantial 813g. Its robust body is built for enthusiasts who demand excellent handling and control.
• W620 is tiny at 98 x 56 x 20 mm, weighing only 116g, perfectly pocketable for casual outings.

Ergonomically, the RX10 II features a grippy, well-contoured body with professional-style controls, including a dedicated top LCD and customizable buttons for quick access. The W620 opts for a minimalist, button-sparse layout - adequate for beginners but limited if you want manual control.

The RX10 II’s tilting 3-inch 1229k-dot LCD and electronic viewfinder (EVF) provide flexibility in composing shots, especially in bright conditions. The W620 has a fixed 2.7-inch screen with just 230k dots and lacks any electronic viewfinder or touchscreen capability, which restricts its usability in challenging lighting or creative angles.

Sensor and Image Quality: The Heart of the Matter

At the core of image quality lies the sensor technology. The RX10 II uses a 1-inch BSI CMOS sensor (13.2 x 8.8 mm) with 20 megapixels, while the W620 uses a 1/2.3-inch CCD sensor (6.17 x 4.55 mm) with 14 megapixels.

Why does sensor size matter? Larger sensors gather more light, offering better dynamic range, lower noise, and enhanced creative control. The RX10 II’s sensor area is roughly 116.16 mm², over 4 times larger than the W620’s 28.07 mm² sensor. This translates directly into superior image quality especially in low light and wide dynamic range scenes.

In my tests, the RX10 II delivers crisp, detailed images with smooth gradations and pleasing color depth, scoring well in DXOMark measurements (score 70 overall). The W620's images, while fine in bright daylight, reveal more noise, reduced detail clarity, and a narrower tonal range when shooting shadows or higher ISOs.

The W620 max ISO tops out at 3200 native, with no RAW support, limiting post-processing flexibility. The RX10 II supports up to ISO 12800 (boosted 25600) with RAW files - valuable for professional workflows.

Autofocus and Shooting Performance: Fast and Accurate vs Basic and Reliable

The RX10 II features a contrast-detection AF system with 25 focus points and face detection, including continuous AF and tracking modes. Although not as advanced as Sony’s later hybrid AF systems, it’s remarkably fast and reliable for a bridge camera released in 2015.

The W620’s AF system is much simpler - single AF with face detection but no continuous tracking or touch AF, limiting its performance in dynamic scenes or when photographing moving subjects.

Here’s what I found in practical settings:

• Wildlife and sports: RX10 II’s continuous AF and 14 fps burst rate excel for capturing fast action. The W620’s 1 fps burst and sluggish AF make it unsuitable for such fast-moving subjects.
• Portraits: RX10 II’s face detection and accurate AF ensure tack-sharp eyes and pleasing bokeh thanks to its bright constant f/2.8 lens. W620’s smaller sensor and slower lens can’t match this.
• Macro: The RX10 II can focus as close as 3 cm with its stabilized zoom lens, offering sharp micro details. The W620’s minimum focus is 5 cm, with less detail resolution.

Lens Versatility: Zoom Range and Aperture

The RX10 II sports a high-quality *Zeiss Vario-Sonnar T 24-200mm (8.3x optical zoom) fixed lens with a constant f/2.8 aperture**, which is exceptional in this zoom range category.

The W620 offers a more modest 28-140mm (5x) zoom with a variable aperture of f/3.2-6.5 that quickly darkens at longer focal lengths.

The RX10 II’s constant f/2.8 aperture enables:

• Better low-light shooting throughout the zoom range
• Greater depth-of-field control for creative blur
• Consistent exposure without aperture shifting when zooming

In contrast, the W620 struggles in dim conditions beyond wide-angle due to its slower aperture, making photos look soft and noise-prone.

Build Quality, Weather Sealing, and Durability

The RX10 II stands out with its environmental sealing, resisting dust and light moisture - essential for outdoor landscape or wildlife photographers working in variable weather.

The W620 lacks such protections, better suited for casual, indoor or fair-weather use.

Display and Viewfinder: Framing the Shot

The RX10 II’s electronic viewfinder with 100% coverage and eye sensor is a boon in bright sunlight where LCD screens wash out. Its 0.7x magnification offers a comfortable shooting experience more akin to DSLRs.

The W620 has no viewfinder and a less bright LCD with low resolution, forcing you to rely on its screen in all conditions, which can be tough outdoors.

Video Capabilities: 4K and Audio Inputs vs Basic HD

The RX10 II supports 4K UHD video recording at 30p, plus Full HD at up to 60p. It also offers mic and headphone ports, giving control over audio quality and monitoring for more professional video production.

W620 only does 720p HD video in Motion JPEG format, with no external audio options - adequate for casual home videos but not serious filmmaking.

Connectivity and Storage

The RX10 II includes built-in Wi-Fi and NFC for instant sharing and remote control via smartphones, plus HDMI output for external monitors. It uses standard SD cards.

The W620 lacks Wi-Fi but supports Eye-Fi card compatibility, a more limited wireless approach. It uses smaller microSD or Memory Stick Duo cards.

Battery Life and Portability

With a larger body and power draw, the RX10 II’s NP-FW50 battery offers about 400 shots per charge. The W620’s smaller NP-BN battery yields approximately 220 shots.

Though RX10 II is heavier, its battery life and versatility make it suitable for all-day sessions, while the W620’s convenience and tiny form factor favor quick snapshots on the go.

Price-to-Performance: Who Gets the Best Bang for Their Buck?

The RX10 II launched around $1,000, reflecting its advanced features and build quality. The W620, priced near $100, targets budget-conscious buyers wanting straightforward point-and-shoot functionality.

Considering raw performance, image quality, and creative potential, the RX10 II justifies its price for enthusiasts and pros. The W620’s value lies in ultra-low cost and pocketability but with tradeoffs in image quality and speed.

• Those not interested in manual controls or the complexity of interchangeable-lens or advanced bridge cameras

Conclusion: One Camera, Two Worlds

These Sony cameras serve vastly different ends of the compact photography spectrum. The RX10 II is a mature, highly capable large sensor superzoom bridging prosumer features and enthusiast needs. It excels in every important technical and user-experience parameter, albeit at a higher price and larger size.

The W620 plays the role of a functional, ultra-budget point-and-shoot aimed at ease of use and portability. Its compromises on zoom, sensor size, and controls limit creative possibilities but make it an exceedingly convenient companion for casual users.

My testing confirms that if you want image quality, speed, flexibility, and professional video, the RX10 II is well worth your investment. Conversely, if you want a simple, pocket-friendly camera to capture everyday moments without fuss, the W620 delivers value that’s hard to beat at its price.
