Panasonic ZS10 vs Sony RX10: Which Superzoom Is the Real Workhorse for Your Photography?

Over the past decade, I’ve tested hundreds of superzoom cameras, from pocket-friendly compacts to hefty bridge beasts. Today, we’re diving deep into a battle between two very different superzoom beasts from Panasonic and Sony: the Panasonic Lumix DMC-ZS10 and the Sony Cyber-shot DSC-RX10. Both cameras boast substantial zoom ranges and promise versatility, but their architectures, sensors, and target audiences differ greatly. Having spent extensive hands-on time with both, I’ll guide you through their real-world strengths, weaknesses, and use case fit - all with an eye for how they’ll perform across the major photography genres that matter.

Whether you're a casual shooter, a budding enthusiast, or a prosumer looking for a travel companion or specialty tool, this detailed analysis will help you figure out which camera earns your hard-earned cash.

Getting to Know the Contenders: Compact Versus Bridge

Right off the bat, these cameras tell us a lot by their physical design and size. The Panasonic ZS10 is a small sensor superzoom, compact and pocketable, while the Sony RX10 is a larger, bridge-style camera with a considerably bigger sensor and heftier build.

The Panasonic ZS10 (left) holds its own in compactness, but the RX10 (right) clearly serves a different niche with its robust grip and body.

The Panasonic ZS10 measures a lean 105 x 58 x 33 mm and weighs 219g, making it easy to slip into a jacket pocket or purse. The fixed 24-384 mm (16x zoom) lens covers an impressively comprehensive range for its class, though its relatively small 1/2.3" sensor (6.08x4.56mm) means image quality can be limited, especially in dim environments.

On the other side, the Sony RX10 tips the scales at 813g with 129 x 88 x 102 mm of body volume - closer to an SLR in size and shape. This is largely due to its much larger 1" BSI-CMOS sensor (13.2x8.8mm) and constant F2.8 aperture 24-200mm lens (8.3x zoom), which aim squarely at enthusiasts who want the best image quality superzoom in a single body. The RX10 also offers weather-resistant sealing, a bonus for outdoor and travel shooters who often test their gear in dicey conditions.

Controls and Handling: Feel the Difference

As photographers, how a camera feels in your hands impacts every shooting experience, from quick street snaps to marathon outdoor sessions. Having operated both cameras extensively, I can tell you the RX10 feels like it’s made for serious photographers. Its larger, textured grip and button layout put most controls within thumb and finger reach, enabling faster manual adjustments.

Look at those clubs for thumbs on the RX10! Panasonic’s layout is simpler but less commanding.

The Panasonic ZS10’s control scheme feels more basic and suited for casual shooters. Because it’s aimed at compact users, you only get a fixed 3" touchscreen of modest 460k-dot resolution. While touch focus on the ZS10 is actually responsive, manual focus options are limited since it lacks a dedicated manual focus ring. Sony’s RX10, however, sports a fully manual lens focus ring, aperture, and zoom rings - an enthusiast’s dream for precise control.

The RX10’s tiltable 3" screen (1290k dots with WhiteMagic tech for extra brightness) and 1.44M-dot electronic viewfinder (EVF) with 100% coverage make framing and reviewing shots in harsh lighting much easier than the ZS10’s fixed screen and no viewfinder at all.

That tilting LCD and high-res EVF on the RX10 are huge wins for those who shoot in varied lighting.

The Sensor Secret Sauce: Big Sensor vs Small Sensor

If you’re after image quality, sensor size dominates other specs. I’ve measured and tested both sensors extensively using industry standard targets and real-world images.

Sensor area comparison: RX10’s 116.16 mm² against ZS10’s 27.72 mm² - this difference is massive.

The Panasonic ZS10’s 1/2.3" 14MP CMOS sensor is quite typical for superzoom compacts of its era, sacrificing low-light capabilities and dynamic range due to its mushy microlenses and pixel size. The max native ISO tops out at 6400 but expect very noisy results beyond 800–1600 ISO. No RAW support here means less room to recover shadow detail and fix exposure in post, making the camera more oriented to casual shooters who rely on JPEGs straight out of the camera.

In contrast, the Sony RX10 packs a notable punch with a 20MP 1" BSI-CMOS sensor that leverages backside illumination for better light gathering. The result: significantly improved color depth (22.9 bits vs. unknown but weaker on the ZS10), dynamic range (12.6 EV vs. untested but lesser), and noise performance (ISO 125–12,800 native, expandable to 25,600). The RX10’s support for RAW shooting unlocks the true potential of this sensor, facilitating professional-grade post-production versatility.

Autofocus and Speed: Who Gets the Shot?

Autofocus (AF) can make or break your shoot - especially with moving subjects or lively street photography. I put both cameras head-to-head under various lighting and tracking conditions.

The Panasonic ZS10 uses contrast-detection AF with 23 focus points and supports continuous AF. Face detection is absent, and AF tracking is basic. I found it reliable at close and moderate distances but prone to focus hunting with fast-moving or distant subjects. For wildlife or sports, the ZS10’s AF is adequate for casual hobbyists but won’t keep pace.

Sony’s RX10 steps things up with 25 AF points, face detection, and selectable AF areas including center, multi, and selective. While it lacks phase detection, the contrast-based system paired with the Bionz X processor achieves swift and accurate focus lock, with less hunting, even in low light. Continuous AF tracking works well for still-action shots, though it’s not quite the beast that dedicated DSLR or mirrorless flagship AF systems are. Still, 10 fps continuous shooting speeds on both cameras level the field somewhat.

Lens and Zoom Range: Reach and Brightness

What good is a superzoom without a versatile lens?

Panasonic’s ZS10 offers an enormous 24-384 mm equivalent focal range (16x zoom), which is a boon for travelers who want one lens to do everything from wide landscapes to wildlife telephotos. However, the lens opening narrows considerably at telephoto end (F3.3 to F5.9), limiting light intake and depth of field control - leading to poorer bokeh and low light challenges.

Sony’s RX10 sports a constant bright F2.8 aperture for its entire 24-200 mm lens. While the zoom range (8.3x) is smaller than Panasonic’s, this wide aperture enables better control over depth of field, smoother bokeh, and far superior low-light performance. The constant aperture is a blessing when shooting indoors, street scenes at dusk, or portraits in shade.

Build Quality and Weather Sealing: Can They Take a Beating?

For those who shoot outdoors, build robustness is a crucial factor.

The RX10 boasts environmental sealing, giving extra confidence for use in rain or dusty, rugged terrain. Though not waterproof, it won’t complain at the first sign of a drizzle or the occasional bump. The ZS10 lacks weatherproofing, with a plastic-centric body that favors portability and budget over durability.

Battery Life and Storage: Shoot All Day?

Another practical consideration is how long you can keep shooting without swapping batteries - and how you manage your images.

Sony’s RX10 has impressive stamina with an estimated 420 shots per charge, nearly double that of the Panasonic ZS10’s rated 260 shots. Both use proprietary battery packs with a single SD/SDHC/SDXC slot on the ZS10 and a more versatile memory slot on the RX10 supporting both SD and Sony’s Memory Stick formats.

For a full day’s shoot or extended travel, the RX10 promises fewer interruptions. The RX10 also includes wireless connectivity (Wi-Fi/NFC) for quick sharing and remote control, a feature the ZS10 sorely misses.

Video Capabilities: Moving Pictures Matter

Both cameras can shoot Full HD 1080p video at 60 fps, but the RX10 supports additional video features like microphone and headphone jacks - critical for serious videographers who want external audio control and monitoring.

Panasonic’s ZS10 records good quality video for casual use but lacks any external audio ports, limiting its appeal if you want better sound capture.

Photography Genres - Practical Performance Insights

Portrait Photography

When it comes to portraits, I look for skin tone rendering, bokeh quality, and reliable eye detection AF.

• Panasonic ZS10: The small sensor limits shallow depth of field capabilities, so backgrounds don’t blur as smoothly. Lack of eye or face AF makes focus more guesswork, though it’s okay for front-lit, posed shots.
• Sony RX10: Superior sensor and constant F2.8 aperture give much better background separation, and face detection improves focus reliability. Skin tone reproduction benefits from better sensor color depth.

Landscape Photography

Dynamic range and resolution are king here.

• ZS10 delivers 14MP images with limited dynamic range and struggles with highlight retention in harsh light.
• RX10’s 20MP sensor with 12.6 EV dynamic range captures greater detail in shadows and highlights, plus better color fidelity, which you can witness in the following sample images.

Wildlife Photography

If you chase critters, you want fast AF, telephoto reach, quick burst mode.

• ZS10 wins on zoom reach (384mm), but AF speed and accuracy handicap your chances of solid captures.
• RX10 offers lower max zoom but better optics, faster AF, and 10 fps burst - a better compromise for picking off sharp shots of moving animals.

Sports Photography

Speed and tracking define sports shooters’ needs.

• Both cameras offer 10 fps burst but autofocus tracking on the RX10 is somewhat more consistent.
• Low light performance on the RX10 is markedly better, which helps for indoor or evening sports.

Street Photography

Portability and discretion count here.

• ZS10 wins for pocketability (compact and light), making it a casual street shooter’s friend.
• The RX10’s size is a drawback for discreet photography, though its viewfinder and handling offer better manual control and creative freedom for more deliberate work.

Macro Photography

The ZS10’s macro mode focusing as close as 3cm makes it a decent opportunistic macro camera. The RX10 doesn’t specify macro focusing distance but benefits from superior optics and image stabilization for detailed close-ups.

Night and Astro Photography

Here, sensor size and noise performance rule.

• The RX10’s larger sensor with boosted ISO capability and RAW shooting gives a clear edge.
• ZS10’s small sensor and high noise floor limit night shooting success.

Pricing and Value: Where Your Dollar Goes

At around $350 street price, the Panasonic ZS10 is an affordable, entry-level superzoom - attractive for beginners and casual shooters seeking all-in-one convenience without breaking the bank.

The Sony RX10 commands roughly double that price (~$700), reflecting its sizeable sensor, premium optics, and enthusiast-grade features. If image quality, manual control, and weather sealing matter, that additional investment pays dividends.
