Sony RX10 III vs Sony WX300

Choosing the Right Superzoom: Sony RX10 III vs Sony WX300 – A Deep Dive for Enthusiasts and Pros

Photography gear choices can sometimes feel overwhelming, especially when comparing cameras that, on the surface, occupy the same category: superzooms. Both the Sony RX10 III and Sony WX300 offer significant zoom reach, promising versatility. But unpacking what’s under the hood reveals an entirely different story. I’ve spent the better part of a decade testing cameras in every conceivable scenario - from landscape to wildlife, from low light to high-speed sports - and today I want to guide you through a thorough comparison of these two Sony superzoom models. We’ll dig into their strengths, shortcomings, and suitability across the broad spectrum of photography disciplines to help you make a clear, confident choice.

Let’s first get a sense of their physical and ergonomic differences.

Size, Handling, and Build: When Size Really Matters

At first glance, the Sony RX10 III looks like a traditional DSLR-style bridge camera with a hefty grip and an almost intimidating lens barrel, while the WX300 is a compact pocket-friendly model. Without handling them, you might underestimate how their size impacts usability and shooting comfort.

The RX10 III physically measures 133 x 94 x 127 mm and weighs around 1051 grams. In contrast, the WX300 is roughly 96 x 55 x 25 mm and only about 166 grams. This is a substantial difference in portability. The RX10’s SLR-like form delivers a comfortable, secure grip, especially useful with the long telephoto lens extended, while the WX300’s compact shape is perfect for travel and discrete street photography.

The weight and bulk of the RX10 III might feel cumbersome for casual or travel shooters but offer better control and stability, especially when shooting in burst mode or using manual settings. Those who prioritize ergonomics and direct physical control will appreciate the RX10’s robust build, weather sealing, and thoughtful design.

Next, take a look at the control interface which greatly influences how quickly you can work in dynamic shooting conditions.

Control Layout: Intuitive Interface Versus Simplified Operation

A camera’s control layout can make or break your shooting workflow, especially for enthusiast and professional users who demand rapid access to settings.

The RX10 III sports a comprehensive set of physical dials - including dedicated rings for aperture and zoom on the lens barrel, exposure compensation, ISO buttons, and a top LCD panel displaying exposure information. This setup empowers you to make quick adjustments without taking your eye off the scene, which is invaluable during fast-paced shooting like sports or wildlife.

Meanwhile, the WX300 offers a more minimalistic button layout befitting its compact design. It lacks dedicated manual controls for aperture and shutter speed, and the screen is fixed rather than articulated. The control simplicity makes it easy to shoot for beginners or those who prefer an automatic experience but limits creative control and responsiveness.

The RX10 III’s control complexity, while initially daunting, unlocks a much richer shooting experience - a tradeoff between convenience and capability.

Now, let’s move inward and examine the heart of the camera: the sensor.

Sensor and Image Quality: Size and Technology Count More Than Megapixels

Sensor size and technology often form the foundation for image quality. Let’s compare the photographic potential of these two cameras from a technical perspective.

The RX10 III uses a 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm with 20 megapixels, whereas the WX300 features a much smaller 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55 mm) with an 18-megapixel count.

What does that mean practically? The RX10 III’s significantly larger sensor area of about 116 mm² translates to superior light-gathering ability, better dynamic range (12.6 EV vs untested but visibly limited on WX300), and improved noise performance at higher ISOs. I conducted controlled low-light tests which showed the RX10 III maintaining sharpness and color fidelity up to ISO 6400, whereas the WX300 images rapidly deteriorated above ISO 800.

The RX10 III also supports RAW capture, essential for post-processing flexibility, while the WX300 lacks RAW support, limiting editing latitude. If image quality ranks high on your priority list - especially for portraits, landscapes, and night photography - the RX10 III’s sensor significantly outperforms the WX300.

While we’re on the topic of composing and reviewing images, let’s examine the rear LCD and EVF options.

Viewing Experience: Articulated Screen and High-Res EVF Make a Difference

Image composition is more than just framing; it’s about seeing the scene accurately and comfortably.

The RX10 III offers a 3-inch tilting LCD with a solid 1.2 million-dot resolution and a high-quality 2.36 million-dot OLED electronic viewfinder (EVF) with 0.7x magnification. This combination provides sharp, immersive framing - even in bright daylight - and offers considerable flexibility for shooting at awkward angles.

The WX300’s 3-inch screen is a fixed, low-resolution 460k-dot panel, and crucially, it has no viewfinder at all. While the LCD is adequate for casual shooting, it can be difficult to see clearly under direct sunlight, and the lack of an EVF can make composition less precise, especially for telephoto shots when holding the camera outstretched.

For anyone intending serious photography in variable lighting or composing more thoughtfully, the RX10 III’s superior viewfinder and screen technology give a tangible advantage.

Speaking of shots - performance hinges largely on autofocus and burst capabilities, especially for active subjects.

Autofocus and Burst Shooting: Precision and Speed for Fast-Paced Moments

Your camera’s autofocus (AF) system and shooting speed dictate its ability to capture decisive moments, whether you’re photographing birds in flight or athletes in action.

The RX10 III employs a contrast-detect AF system with 25 focus points and face detection, plus continuous AF modes that can track moving subjects efficiently, linked with a rapid 14 fps burst rate. In real-world testing, this results in accurate focus lock and tracking even on moderately fast wildlife or sporting events, although it can occasionally struggle in extremely low contrast scenarios.

The WX300 offers a single AF mode with face detection but lacks continuous AF and has a slower 10 fps burst rate with limited tracking capabilities. In practice, it’s fine for casual snapshots but unsuitable for demanding action photography.

That advanced AF combined with robust burst speed makes the RX10 III a more versatile tool for shooting subjects that won’t hold still.

How about the lenses since these cameras are superzooms?

Lens Versatility: Zoom Ranges and Aperture Advantages

Superzoom cameras promise versatility by packing extensive focal length ranges into a single lens body. But here, differences matter in terms of reach and image brightness.

The RX10 III’s fixed 24–600 mm equivalent lens offers an impressive 25x zoom range with a fast maximum aperture of f/2.4 at the wide end, narrowing to f/4.0 at 600 mm. This bright aperture range outperforms the WX300’s 25–500 mm (20x zoom) with a maximum aperture of f/3.5–6.5, meaning the RX10 III lets in substantially more light at the telephoto end.

This aperture advantage equips the RX10 III to create creamy bokeh for portraiture and isolate subjects with shallow depth of field, which is impossible on the WX300’s slower lens. The RX10 III’s macro capabilities, allowing focusing as close as 3 cm, also enable detailed close-ups for nature or product photography - a feature missing on the WX300.

Overall, the RX10 III delivers pro-level zoom reach with superior lens speed, while the WX300 prioritizes compact convenience with acceptable - but slower - telephoto reach.

Next, I’ll share how these translate across various photography genres.

Portraits: Skin Tones and Eye Detection

If beautiful, natural skin tones and sharp eye focus matter to you, the RX10 III is the clear winner. Its larger sensor and superior color depth (measured at 23.1 bits on DxO Mark) capture subtle tonal variations and better dynamic range. The external flash with a reach of 10.8 meters helps fill shadows naturally, essential in portraiture.

The face detection and eye autofocus systems in RX10 III accurately lock focus on eyes in both stills and videos, something missing or rudimentary on WX300. The WX300, with its smaller sensor and less capable AF, renders portraits flatter with less background separation and softer focus on critical areas.

Landscapes: Detail, Dynamic Range & Durability

Landscape photography demands high resolution, dynamic range for shadow and highlight recovery, and a durable build.

The RX10 III’s 20MP sensor resolution and 12.6 EV dynamic range provide plenty of detail and flexibility when processing RAW files. Weather sealing ensures reliability in adverse outdoor conditions - a notable advantage for hiking photographers.

The WX300’s lack of environmental sealing and its smaller sensor limit both image quality and durability outdoors. While the WX300 can serve beginners for casual landscapes, serious enthusiasts will find it wanting.

Wildlife Photography: Autofocus Speed and Telephoto Reach

Capturing elusive wildlife requires fast autofocus, long reach, and rapid shooting.

The RX10 III’s 600mm reach and 14 fps shooting aid in framing and freezing animal movement. Though it lacks phase-detect AF, its contrast detection combined with predictive tracking works well in daylight.

The WX300 maxes out at 500 mm but with the slower aperture and less accurate AF, making it harder to nail shots of quick or distant animals. Plus, the smaller sensor struggles with noise at higher ISOs needed in shaded forest environments.

Sports Photography: Tracking Performance in Action

For sports, continuous autofocus and fast burst rates ensure critical moments aren’t missed.

The RX10 III beats the WX300 here hands-down, delivering continuous AF tracking and a fast 14 fps burst with mechanical shutter. This lets you capture fast sequences like runners or cyclists reliably.

The WX300’s lack of continuous AF and slower shooting rate limits it to static or slow-moving targets.

Street and Travel: Discretion and Portability

Here size and portability play a big role.

The WX300 is ideal for street and travel shooters wanting a pocketable companion with decent zoom. Its lightweight compactness makes it easy to carry all day and less conspicuous in urban settings.

The RX10 III, while versatile, is bigger and heavier, less discreet but offers superb image quality and creative control for serious travellers willing to trade portability for performance.

Macro Photography: Close-Up Capabilities

Macro work thrives on close focusing and stabilization.

The RX10 III’s macro focus down to 3 cm and optical image stabilization make it reliable for sharp, detailed close-ups. The WX300 does not offer dedicated macro capabilities, so it’s less suitable for photographing small subjects.

Night and Astro Photography: High ISO Performance

Low light demands noise control and dynamic range.

RX10 III excels due to its larger sensor and good ISO performance, preserving details in shadows and highlights, even handheld at moderate exposures.

The WX300’s small sensor creates noisy, muddy images in dim conditions and lacks features like long exposure control for astrophotography.

Video Features: High-Quality Capture and Audio Support

These days, video is often as important as stills.

The RX10 III records 4K UHD video at 30p with XAVC S codec, supports built-in microphone input, and headphone monitoring - features essential for serious videographers.

The WX300 limits video to Full HD 1080p and lacks microphone or headphone jacks, reducing control over audio quality.
