Panasonic Lumix S5 vs Sony RX10 II: A Deep Dive Into Two Very Different Cameras

As a photography gear reviewer who’s logged thousands of hours with cameras across all price points and genres, I’m often asked: Which is better, a serious full-frame mirrorless or a large-sensor superzoom bridge camera? Today, let’s pit the Panasonic Lumix DC-S5 against the Sony Cyber-shot DSC-RX10 II to answer that. These two cameras represent completely different design philosophies and price brackets - but both have their loyal fans. By unpacking their strengths, weaknesses, and performance across real-world photography genres, I’ll help you figure out which makes more sense for your needs.

Size and Handling: Bulk vs. Bridge Camera Practicality

First impressions count, and grip comfort plays a huge role when you’re hauling a camera all day. The Panasonic S5 is a pro-level mirrorless with a classic DSLR-style body, whereas the Sony RX10 II is a large, bridge-style superzoom.

In-hand, the S5 feels substantial but balanced at 714 grams and a fairly compact 133 x 97 x 82 mm housing. Panasonic has nailed ergonomics here: the grip is firm without feeling bulky, and all buttons fall logically to the fingers. This camera is designed for extended shooting sessions - the kind pro shooters demand.

The Sony RX10 II, at 813 grams and chunkier dimensions (129 x 88 x 102 mm), leans into the bridge camera mold. It’s deceptively big for what is essentially an all-in-one zoom camera. The larger lens profile eats into portability slightly but offers convenience: no lens changes necessary.

For travelers or street photographers who prioritize size and fast handling, the Panasonic S5’s smaller footprint and better grip customization (though no illuminated buttons, a minor miss) take the lead.

Design and Controls: Intuitive Layouts with Pro Intent

Control layout can make or break the shooting experience - especially when you need to adjust settings on the fly.

The S5 offers a clean top-plate with direct access dials for shutter speed, exposure compensation, and a mode dial - all illuminated for quick night use (though without button illumination, pushing in the dark requires familiarity). The inclusion of dual SD card slots shows professional ambition, allowing simultaneous backups or overflow.

The RX10 II sticks to simpler controls with a single storage slot but compensates with a built-in pop-up flash and a top display panel (rare for bridge cameras) that gives quick status info. While fewer physical buttons slow manual fiddling, the mode dial and lens rings feel smooth and precise.

The Panasonic’s fully articulated 3.0-inch touchscreen with 1840k dots leads in versatility, supporting touch-to-focus and menu navigation - a boon in video and macro work. The RX10 II’s 3.0-inch tilting screen suffers with lower 1229k resolution and lacks touchscreen functionality.

If you want a camera that feels like a tool rather than a gadget - with all controls right where you want them - the S5 wins. But for casual shooters wanting quick zoom range in a small package, the RX10’s simpler controls suffice.

Sensor and Image Quality: The Full-Frame Edge vs. Compact Powerhouse

At the heart of any camera is its sensor, the key determinant of image quality and flexibility.

The Panasonic S5 boasts a full-frame CMOS sensor measuring 35.6 x 23.8 mm with 24 megapixels and no anti-aliasing filter, letting it capture incredibly sharp images with less moiré. This sensor size results in a generous 847.28 mm² surface area, greatly benefiting low-light performance, depth of field control, and dynamic range.

In contrast, the Sony RX10 II sports a 1-inch BSI-CMOS sensor (13.2x8.8 mm), notably smaller at 116.16 mm² and 20 megapixels resolution. While smaller sensors generally mean more noise in low light and less shallow depth-of-field control, Sony’s sensor tech and Bionz X processor work well to mitigate these limits.

According to DxOMark tests, the RX10 II scores an overall 70, with solid color depth (23 bits) and dynamic range (12.6 EV), but its low-light ISO performance peaks around 531 - noticeably inferior to full-frame standards.

Overall, for landscape, portrait, and professional-level work demanding maximum image quality, the Panasonic S5’s sensor outperforms by quite a margin. But for casual zoom shooters or video vloggers, the RX10 II’s sensor still produces very pleasing results if you keep ISO moderate.

Autofocus Systems: Precision vs. Speed in Different Contexts

The autofocus system dictates how fast and accurately cameras lock onto subjects - a decisive factor for wildlife, sports, and street photography.

The Panasonic S5 employs a 225-point contrast-detect AF system with face detection, touch focus, and continuous tracking. Although it lacks phase-detection pixels on the sensor (a bit surprising for this generation), Panasonic’s Depth From Defocus algorithm updates AF rapidly with good reliability. It also supports focus bracketing and focus stacking for macro enthusiasts and advanced portrait shooters.

Sony RX10 II features a more modest 25-point contrast-detect AF, no phase detection, and face detection support. Being an older design, it cannot match newer autofocus systems’ speed or subject tracking sophistication.

Neither camera offers animal eye AF, limiting their effectiveness for serious wildlife photographers relying on that tech.

Thanks to its advanced sensor readout and algorithms, the S5 wins in autofocus accuracy and tracking, especially in continuous mode. The RX10 II can still deliver quick autofocus on static subjects and benefits from optical image stabilization for handheld ease.

Burst Shooting and Buffer Depth: Catching the Unpredictable

When shooting sports or wildlife, burst speed and buffer size can be crucial for nailing the perfect moment.

The Panasonic S5 delivers a respectable 7 fps continuous burst, best for many enthusiasts and some semipro use. Buffer depth remains ample for 24 MP RAW files, thanks to decent onboard processing.

In contrast, the RX10 II shoots wildly faster at 14 fps, a throwback to its emphasis on action shooting - a rare speed for a bridge camera. However, its smaller buffer and older processor mean the sustained burst length is more limited, particularly in RAW.

For pro sports shooters, neither camera is ideal compared to flagship bodies, but the RX10 II offers burst speed advantages for wildlife or fast events, especially if you’re shooting JPEGs.

Image Stabilization: Sensor-Shift vs. Optical Solutions

Stability can make or break sharpness at slower shutter speeds or long focal lengths.

Panasonic’s S5 features a sensor-based 5-axis image stabilization, capable of compensating for pitch, yaw, roll, and shift movements. This system offers solid stabilization even with non-stabilized lenses, and combines nicely with stabilized Leica L lenses.

Sony RX10 II employs an optical image stabilization system built into the lens assembly, optimized for the fixed 24-200 mm f/2.8 lens. This works well for telephoto and hand-held shooting, though optical IS can be less effective than advanced in-body stabilization for extreme situations like macro or video gimbal use.

In practical shooting, the Panasonic S5’s IBIS wins by delivering more versatile and powerful stabilization across lenses and situations, especially useful in low light or handheld video.

Video Capabilities: Hybrid Shooting for Modern Creators

Both cameras push video beyond stills, but the S5 leads as a hybrid masterpiece.

Panasonic S5 supports 4K UHD recording up to 60p at 10-bit 4:2:0 internally or 4:2:2 externally via HDMI, codecs like H.264 and H.265, and offers advanced video features like V-Log recording, LUTs, and waveform monitoring. Dual card slots help continuous video recording or backup. Plus, a mic and headphone jack make it suitable for serious videographers.

The RX10 II offers 4K UHD at 30p max (no 60p) and HD up to 60p, with AVCHD and XAVC S codec options. It also includes mic and headphone ports. However, lack of 10-bit internal recording or advanced video features limit its suitability for pro video work.

If you plan significant hybrid work - mixing pro-grade photos and high-quality video - the Panasonic S5 has much more to offer.

Battery Life and Storage: Long Sessions vs. Moderate Usage

The Panasonic S5 uses a proprietary battery with a rated 440 shutter actuations per charge - good but not class-leading. Thanks to USB charging capability, it supports on-the-go top-ups from power banks - a massive plus for travel photographers.

Sony RX10 II’s older NP-FW50 battery is slightly less enduring at 400 shots per charge and lacks USB charging, demanding more careful power management.

Dual SD card slots on the Panasonic make offloading and data security easier for pros, whereas the RX10 II’s single SD slot and additional Memory Stick support reflect its age.

Lens Ecosystem and Flexibility: Fixed Zoom vs. Leica L Mount Support

The RX10 II is an all-in-one solution with a versatile 24-200 mm f/2.8 zoom, perfect for users who dislike changing lenses. This zoom covers wide-angle to moderate telephoto with a fast aperture - great for walk-around shooting and low light. The macro focusing distance of 3 cm is also impressive.

However, fixed lenses limit creative control and potential upgrades.

In contrast, the Panasonic S5 accepts Leica L-mount lenses from Panasonic, Sigma, and Leica themselves, landing a rapidly growing, high-quality lens ecosystem. The ability to swap primes and zooms for specialized use (macro, portrait, wildlife) vastly expands creative potential.

For enthusiasts or pros seeking ultimate versatility, the S5 clearly wins.

Build Quality and Weather Sealing: Ruggedness for Serious Use

Both cameras sport weather sealing and sturdy builds, though the S5 feels more solid with magnesium alloy chassis designed to withstand dust and splashes.

RX10 II's build is resilient for a bridge camera, with environmental sealing, but its plastic-heavy construction means it won’t hold up as well to heavy professional use or harsh environments.

For photographers shooting outdoors in tricky weather, the Panasonic’s pro build inspires greater confidence.
