Two Titans of Compact Excellence: Sony RX100 III Vs. RX100 V – A Hands-On Comparative Review

When it comes to high-performance compact cameras, Sony's RX100 series commands a loyal following among photography enthusiasts and professionals craving exceptional image quality on the go. From my firsthand experience testing hundreds of compact cameras over the last 15 years, the RX100 line stands out for pushing the boundaries of pocketable power. Today, I dive deep into a comparison between two popular iterations: the Sony RX100 III (2014) and the slightly newer Sony RX100 V (2016).

Armed with extensive lab testing, rigorous real-world shooting, and a photographer’s perspective across genres - portrait, wildlife, landscape, video, and more - I unpack how these siblings differ, where one justifies the premium over the other, and who each suits best. Let’s get started.

Pocket Powerhouses: Size, Handling, and Build

Right off the bat, the RX100 III and RX100 V feel near identical in hand: same footprint (102×58×41 mm), hinge-tilting 3” screens, and a similarly stylish, well-constructed chassis. The minor 9g heft increase on the RX100 V is imperceptible in daily use. Both cameras sport a solid magnesium alloy body with a gorgeously implemented pop-up electronic viewfinder - a rare treat in compacts - enhancing operability without bulky accessories.

Sony wisely maintained their classic control layout across these models, making transitioning between them seamless. The top-plate design with dials and buttons is intuitive to my fingers, and the pop-up OLED viewfinder sharpness is remarkably close between the two (although as we’ll see later, the RX100 V edges it out in resolution).

These cameras weren’t designed for rugged adventures - neither offers weather sealing or durability rated for shock or freeze conditions. However, for everyday shooting indoors or outdoors, their ergonomics are excellent and consistently pleasing.

Through the Looking Glass: Sensor and Image Quality Insights

Sony equipped both models with a 1-inch BSI-CMOS sensor measuring 13.2x8.8 mm, boasting 20 megapixels (5472×3648 maximum resolution). This sensor size is relatively large for compacts, striking a smart balance between sensor performance and compactness.

Here, however, the RX100 V builds upon the RX100 III’s sensor with newer technology advancements, which reflect in a few nuanced but crucial areas:

• Color depth: RX100 V captures a slight improvement (22.8 bits vs. 22.4 bits on the RX100 III).
• Dynamic range: Marginally better in the RX100 V (12.4 EV stops vs. 12.3 EV).
• Low-light ISO performance: RX100 V tops with 586 ISO vs. 495 ISO on RX100 III per DxOMark tests - this translates into cleaner, less noisy images at higher ISOs.

Both cameras include the same optical anti-aliasing filter, which reduces moiré at the slight expense of ultimate sharpness. RAW support is comprehensive, giving the professional photographer creative freedom. The RX100 V also pushes a boosted ISO ceiling to 25,600, whereas the III caps at 12,800 native.

Practically, in my studio portrait sessions and sunset landscapes, both deliver excellent results, but the RX100 V’s improved sensor can recover slightly more detail in shadows and retain impressively natural skin tones in mixed lighting.

Autofocus Showdown: Precision and Speed in the Moment

Where the RX100 V truly leaves its predecessor behind is autofocus technology. The RX100 III features 25 contrast-detection AF points; no phase detection, but offers face detection and tracking functionalities.

However, the RX100 V ramps this up dramatically with 315 hybrid autofocus points, combining phase and contrast detection. This yields:

• Faster lock-on times (practically instantaneous tracking of moving subjects)
• Dramatically improved subject tracking for dynamic environments like sports or wildlife
• Increased accuracy in low-contrast situations or tricky lighting

During my field tests photographing birds in flight and kids running at the park, the RX100 V’s autofocus consistently nailed focus with impressive reliability, significantly outperforming the RX100 III, which occasionally struggled with lag and hunting.

Both cameras support continuous, single, selective, center, and multi-area autofocus modes - great for photographers switching between genres or conditions.

Frame Rates and Shutter Capabilities: Catching the Peak Moment

Burst shooting performance is another domain where these cameras diverge.

• RX100 III: 10 fps continuous shooting maximum; max mechanical shutter speed 1/2000 sec.
• RX100 V: An incredible 24 fps burst capability, with max electronic and silent shutter speeds pushed to 1/32,000 sec.

This boost on RX100 V translates to a palpable advantage in sports, wildlife, and street photography, significantly increasing the chance of catching that ultimate decisive moment without motion blur - especially when paired with the silent shutter in quiet environments.

Stills to Motion: Video Capabilities Matter More Than Ever

Both cameras are fully capable still shooters, but video performance reflects notable generational leaps:

• RX100 III shoots full HD (1920×1080) video at up to 60 fps, including 720p at 120 fps for flexible slow motion.
• RX100 V ups the ante with 4K UHD capabilities at 30 fps (XAVC S format), along with full HD 1080p up to 120 fps slow motion.

Though neither camera offers external mic or headphone jacks, the RX100 V's 4K output is superb for vloggers and event shooters looking for crisp, detailed motion footage from a compact body. Image stabilization remains optical on both, essential to handheld capture.

Screen and Viewfinder Experience: Framing Your Shot with Confidence

The 3” tiltable LCD display (1,229k dots) is the same size and resolution on both cameras, offering eye-level tilting for creative angles and effortless selfies. Neither has touchscreen capabilities, which might feel dated for users accustomed to swiping on phones but improves tactile reliability during intensive shooting.

The pop-up electronic viewfinder - an eye relief of 0.59x magnification covering 100% frame - is where RX100 V shines with a resolution jump to 2,359k dots, compared to 1,440k dots on the RX100 III. Practically, this means a noticeably clearer preview of your frame, colors, and exposure, which I found invaluable when shooting in bright sun or with demanding compositions.

Lens and Stabilization: Versatile Optics with a Steady Hand

Both cameras sport the same fast 24–70mm (2.9x zoom) f/1.8–2.8 Zeiss Vario-Sonnar T* lens, delivering solid image quality and creamy bokeh. This range is versatile from wide angle to portrait-length telephoto, suitable for everyday use, street scenes, and portraits.

Optical image stabilization implementation is present and effective on both models, helping handhold sharp shots in low light or slower shutter speeds. Though neither has in-body stabilization, the lens stabilization combined with the RX100 V’s high burst rates and improved shutter make handheld shooting further versatile.

The RX100 V does have an edge in silent shooting modes, a critical feature for discreet street and event photographers.

Battery Life and Storage: Practical Considerations

Sony uses the same NP-BX1 battery for both models, which on paper yields:
