Sony RX100 III vs RX100 VII: A Detailed Comparison of Two Iconic Compact Cameras

When it comes to premium large-sensor compacts, Sony’s RX100 line has long held a special place in the hearts (and pockets) of enthusiasts who demand serious performance in a truly pocketable package. Today, we’re diving deep into a head-to-head comparison between two notable entries in this lineage - the Sony RX100 III, announced in 2014, and its relatively recent descendant, the RX100 VII from 2019. Both pack a 1-inch sensor into a compact body with fixed zoom lenses, promising world-class image quality coupled with versatile handling, but they were designed for different eras and user expectations.

Over my 15+ years testing cameras across all genres, I’ve held many RX100 variants in my hands - so I’ll be weaving first-hand impressions, technical analysis, and real-world shooting insights to help you decide which of these cameras suits your style best. We’ll cover everything from sensor performance and lens capabilities to ergonomics and video chops, with a firm eye on how each stands up in portrait, wildlife, macro, travel, and more.

Let’s roll.

First Impressions: Size, Build, and Handling

Sony’s RX100 line is famous for delivering large-sensor quality in an ultra-portable chassis. Despite the years between these two models, their physical footprints are remarkably similar, with only minor weight and depth differences. The RX100 III weighs 290g and measures approximately 102x58x41mm - while the RX100 VII adds just a touch of bulk and weight at 302g and 102x58x43mm.

Handling-wise, both offer a similar form factor that feels confident in the hand, featuring a substantial grip for such compactness. However, subtle refinements in button placement and control layout on the RX100 VII enhance usability, especially during fast-paced shooting.

Looking at the top-down design, the RX100 III features a minimalist approach with a mode dial, shutter release, zoom ring, and a pop-up electronic viewfinder (EVF). The RX100 VII, though visually similar on top, introduces expanded control customization, improved button tactile feedback, and a more responsive electronic shutter system.

In practical handling terms, I found the RX100 VII to be more intuitive in prolonged sessions. The addition of a fully articulating touchscreen (absent on the RX100 III) significantly speeds up menu navigation and focus selection - a boon when you’re chasing critical focus in dynamic environments.

Sensor and Image Quality: The Heart of the Matter

Both cameras employ a 1-inch type BSI-CMOS sensor measuring 13.2 x 8.8 mm, offering 20MP resolution, which has become Sony’s signature sweet spot for balancing sensor size and compact portability.

Technical sensors specs are near-identical: same sensor size and approximate resolution, and both with anti-aliasing filters. However, subtle differences in processing and ISO handling set them apart:

• The RX100 III’s base ISO is 125 with max native ISO up to 12,800.
• The RX100 VII extends this range slightly further on the low end to ISO 64, touted as a low-boost ISO setting, which helps in bright conditions for wider apertures and lower motion blur.

On paper, the RX100 III boasts a slightly better DxO Mark overall score (67 vs. 63 for RX100 VII), with stronger color depth (22.4 bits vs. 21.8) and better low-light ISO performance (495 vs. 418), though the RX100 VII marginally improves dynamic range by 0.1 EV.

How does this translate to real-world use? In controlled studio conditions and daylight, both produce crisp, detailed files with typical 1-inch sensor characteristics: excellent for web and print up to A3 size, with minimal noise at ISO 125-400. The RX100 III edges out slightly in color depth - subtle but noticeable in delicate skin tones during portraits, preserving natural hues with less processing needed. Meanwhile, the RX100 VII’s improved dynamic range forgiveness gives it a slight advantage in high-contrast landscapes, recovering blown highlights with more latitude.

Autofocus Systems: Precision and Speed for Every Situation

Between 2014’s RX100 III and 2019’s RX100 VII, Sony radically improved autofocus technology - as you might expect over five years.

The RX100 III employs a 25-point contrast-detection autofocus (CDAF) system. It offers face detection and eye detection, but no phase detection pixels or advanced tracking. It performs well in good light but can struggle in low contrast or dim environments, sometimes hunting noticeably.

The RX100 VII is fitted with a hybrid AF system combining phase detection and contrast detection, significantly boosting acquisition speed and accuracy. Its autofocus features include:

• Real-time Eye AF for humans
• Real-time Tracking AF facilitated by AI algorithms
• Animal Eye AF for pets and wildlife - absent in RX100 III
• Touchpad AF on the LCD, enhancing focus point selection

This makes the RX100 VII a star in fast-moving subjects, wildlife photography, and action shots - a distinct advantage over the RX100 III’s more pedestrian AF.

Lens Versatility and Optical Performance

The biggest operational difference between the two is their respective fixed zoom lenses.

• RX100 III: 24-70mm (2.9x zoom) F1.8–2.8 aperture range - fast and sharp even wide open, ideal for portraits and low-light work
• RX100 VII: 24-200mm (8.3x zoom) F2.8-4.5 aperture - super versatile for wildlife, sports, and travel, but slower optics at the telephoto end

This difference shapes what types of photography each camera is best suited for.

The RX100 III’s bright aperture enables creamy, pleasing bokeh, particularly handy in portrait shooting. The shorter zoom range keeps distortion minimal, with excellent sharpness edge-to-edge through 70mm. Macro work benefits from a 5cm close-focus range with strong subject isolation.

On the other hand, the RX100 VII's zoom extends significantly into telephoto territory at 200mm, allowing you to capture distant wildlife or track athletes in motion - but at the cost of a variable aperture narrowing to f/4.5 at 200mm, reducing low-light capabilities and depth-of-field control. The macro focusing distance is slightly longer at 8cm, and while not poor, the bokeh is less creamy given the narrower max aperture.

In practice, during a landscape shoot, the RX100 III offers more uniform sharpness and superior control over depth of field at moderate focal lengths. If wildlife or telephoto reach is your priority, the RX100 VII’s impressive zoom serves admirably, albeit with diminished background blur and higher ISO needs in shadows.

Display and Viewfinder: Information at Your Fingertips

The rear screen and EVF are the main interfaces photographers interact with for framing and review. Sony has evolved these elements markedly.

The RX100 III sports a 3-inch tilting LCD screen with a resolution of 1229k dots - but unfortunately, no touchscreen functionality. It also includes a pop-up EVF at 1440k dots and 0.59x viewfinder magnification.

The RX100 VII maintains the 3” tilting screen but lowers pixel density slightly to 921k dots, compensating by adding a fully articulating touchscreen, enabling intuitive focus point selection and quick menu access. This makes the RX100 VII significantly more versatile for vlogging, selfies, and complex compositions.

Meanwhile, the RX100 VII's EVF sees a hefty upgrade: a 2360k-dot OLED, making focusing and exposure evaluation in bright light more precise and comfortable.

My testing confirms the RX100 VII’s screen vastly improves usability in varied shooting angles - street photography, macro close-ups, or overhead shots - while its EVF offers more detail and less lag.

Burst Shooting and Buffer: Catching the Decisive Moment

For sports and wildlife enthusiasts, buffer depth and shoot speed often make or break the experience.

• RX100 III: 10fps continuous shooting
• RX100 VII: 20fps burst, double the speed, with a substantial buffer for dozens of RAW shots

The RX100 VII also boasts a remarkable 1/32,000s electronic shutter for ultra-fast freezing of motion and silent shooting - capabilities the RX100 III lacks. This allows shooting wide-open in bright sunlight and capturing fast action discreetly.

In field tests at a local soccer match, the RX100 VII’s tracking AF and fast burst rate yielded considerably more usable frames of rapid movement versus the RX100 III’s respectable but slower approach.

Video Capabilities: Moving Image Excellence

Sony has steadily improved video functions in the RX100 series:

• RX100 III records Full HD 1080p up to 60fps with standard codecs (AVCHD, MPEG-4, XAVC S).
• RX100 VII supports 4K UHD video (3840x2160) at 30fps with advanced codecs and higher bitrates (XAVC S at 100 Mbps). It also includes slo-mo up to 960fps but limited to HD resolution.

The RX100 VII further adds a microphone input jack - a critical feature for serious vloggers and documentarians - missing from RX100 III.

Both have built-in optical image stabilization, but the RX100 VII incorporates improved algorithms and active electronic stabilization modes, resulting in smoother handheld clips.

I recorded night cityscapes and interviews with both: RX100 VII’s enhanced video quality and audio flexibility easily make it the preferred choice for video-centric users.

Battery Life and Connectivity: Staying Powered and Connected

Battery life differences favor the RX100 III, which offers around 320 shots per charge compared to 260 on the RX100 VII - likely a trade-off for the latter’s enhanced processing and screen features.

Both use the proprietary NP-BX1 battery model, so spare battery choice and charging accessories remain consistent.

Connectivity-wise, the RX100 VII adds Bluetooth alongside Wi-Fi and NFC, affording seamless pairing with mobile devices and location tagging. RX100 III offers Wi-Fi and NFC but no Bluetooth.

For photographers on the go, especially travelers and content creators, these connectivity upgrades provide tangible convenience.
