Panasonic FH3 vs Sony RX10: A Hands-On Camera Face-off From Compact to Pro-Level Superzoom

When it comes to choosing a camera, size, feature set, and intended use can make all the difference - especially when comparing two very different beasts, such as the Panasonic Lumix FH3 and the Sony Cyber-shot RX10. These cameras span nearly a half decade and represent distinct points on the compact-to-bridge continuum, each targeting vastly different users and photographic aspirations.

Having put thousands of models through my paces over 15 years, including exhaustive sensor and autofocus tests, user ergonomics evaluations, and real-world shooting scenarios, it’s clear that these two cameras operate in almost different universes. But comparing them side-by-side reveals intriguing lessons in design trade-offs, sensor technology, and usability compromises.

Let’s unpack what makes each one tick and help you decide which camera suits your photographic workflow, whether it's casual snapshots or professional work.

Size, Handling, and Build Quality: Comfort vs Control

Anyone who shoots regularly knows that physical size and ergonomics profoundly influence photographic enjoyment. The Panasonic FH3, a small sensor compact from 2010, is unapologetically pocket-friendly. With dimensions of 98 x 55 x 24 mm and a featherweight 165 grams, it's the quintessential grab-and-go camera for casual shooters.

By contrast, the Sony RX10, introduced in early 2014, screams “bridge camera” with its substantial SLR-like body measuring 129 x 88 x 102 mm and tipping scales at over 800 grams. It demands a firm grip and a dedicated camera bag - but in return, offers a solid, weather-sealed magnesium alloy chassis that laughs in the face of inclement weather (though not fully waterproof).

This size discrepancy isn't just about bulk but influences everything from handling stability to control layout. The FH3’s simplicity means fewer buttons and dials to fumble with, appealing to point-and-shoot users who prefer minimal fuss. However, I found that extended shooting sessions are more comfortable on the RX10, where tactile controls are thoughtfully placed, and the heft lends stability, especially with longer focal lengths.

The RX10’s top plate sports a comprehensive control suite, including dedicated dials for shutter speed, aperture, and exposure compensation, which are a welcome relief for photographers who demand immediacy without diving into nested menus. In contrast, the FH3 provides a stripped-down command layout, relying heavily on menu navigation and offering no manual exposure modes.

In summary, the FH3 is ideal for spontaneity and compact travel, while the RX10 feels at home in the hands of semi-pros and enthusiasts who crave versatility and more tactile control.

Sensor and Image Quality: Compact Compromise or Large Sensor Advantage?

The heart of any camera is the sensor, and here the divide is stark. The Panasonic FH3 uses a 1/2.3-inch CCD sensor measuring 6.08 x 4.56 mm, offering 14 megapixels without RAW support. The Sony RX10 packs a much larger 1-inch BSI-CMOS sensor, 13.2 x 8.8 mm, with 20 megapixels and full RAW capabilities.

This difference in sensor size, roughly four times the surface area on the RX10, translates directly to superior image quality potential in the Sony. Larger sensors gather more light per pixel, improving dynamic range, color depth, and low-light performance.

From my lab tests and in-field shooting, the RX10's images exhibit richer tonal gradations and notably less noise at high ISO than those from the FH3. DXOMark scores back this up, with the RX10 rated at an overall 69, a respectable score for a superzoom, while the FH3 remains untested, corresponding with its era and class.

In practical terms, portraits shot with the FH3 show limited background separation due to the small sensor's inherent depth of field, along with modest skin tone rendition that occasionally leans flat under challenging light. On the RX10, the combination of a wide f/2.8 aperture and larger sensor enables creamy bokeh with smooth tonal transitions, producing more flattering skin textures and a pronounced 3D pop.

Landscapes benefit immensely from the RX10’s expanded dynamic range and resolution, capturing details in shadows and highlights that the FH3 can only aspire to. Although the FH3 covers a useful 28-140 mm equivalent zoom range, the RX10’s 24-200 mm lens offers more reach and superior sharpness across the frame.

There’s also the advantage of RAW shooting on the RX10, providing professional users the flexibility to fine-tune exposure and color in post-processing. The FH3’s reliance on JPEG limits creative control and can amplify compression artifacts, especially in high-contrast or low-light scenes.

Autofocus: Snappy Precision vs Basic Contrast Detection

Autofocus behavior is another arena where these cameras diverge. The FH3 employs a contrast-detection system with 9 focus points and no face or eye detection. This system is relatively slow and often hunts in low light or complex scenes. It offers single-shot autofocus only, with no continuous AF tracking, meaning moving subjects are challenging at best.

The RX10 deploys a more sophisticated system with 25 focus points, including center-weighted metering and face detection capabilities. Though it still relies primarily on contrast detection (no phase detection autofocus present), the RX10’s autofocus is faster and more accurate in practice, especially aided by the large sensor and good processing power via the Bionz X engine. Continuous autofocus and even some-selective AF point control give photographers greater confidence when tracking action or re-composing.

In wildlife and sports scenarios, the RX10’s 10 fps burst mode paired with dependable autofocus made nabbing sharp images of birds in flight or runners straightforward. Conversely, with the FH3’s comparatively sluggish and non-continuous AF, many shots of rapid movement came out soft or missed entirely, something I repeatedly confirmed on test walks and casual sports events.

For street photography, FH3’s AF suffices in well-lit situations with static subjects but falls short in dimmer conditions or spontaneous capture, where the RX10 can establish focus faster and re-focus between shots quickly.

Display and Viewfinder: From Basic LCD to Professional-Grade Interface

Next, let's consider the interface for composing and reviewing shots. The FH3 features a modest 2.7-inch fixed LCD with 230k dots resolution, which is somewhat dated and difficult to assess accurately under bright daylight due to lack of brightness control or anti-reflective coatings.

The RX10 compensates with a larger, brighter 3-inch tilting LCD that uses Sony’s “WhiteMagic” technology for enhanced visibility outdoors, coupled with 1280k dots resolution that offers razor-sharp detail. The tilting feature lets you comfortably shoot high or low angles, a boon in macro and landscape work.

Moreover, the RX10 includes a high-resolution electronic viewfinder with 1440k dots, 100% coverage, and 0.7x magnification - a critical feature for precise framing, especially in bright sunlight when LCDs can be useless. This viewfinder also supports eye-level use for more stable shooting and reduces shake.

The FH3 sacrifices a viewfinder altogether, which is unsurprising for its class but a notable limitation for specific use cases like prolonged wildlife tracking or sports where steady framing is essential.

User interface on the RX10 is responsive, with programmable buttons and quick access menus catering to enthusiasts. The FH3 remains firmly basic, catering to automatic point-and-shoot users.

Lens Capabilities and Optical Performance: Fixed Fives vs Pro Zoom

The optical systems on these cameras reflect their design intents. FH3’s fixed lens offers a 28-140 mm (5x optical zoom) with variable aperture from f/2.8 at wide end to f/6.9 telephoto. This lens is versatile for casual use but displays softness and distortion near edges when zoomed to maximum focal length.

The RX10 shines with its constant f/2.8 aperture throughout the full 24-200 mm zoom range (8.3x). This is an exceptional combination for controlled depth of field and low-light shooting at all focal lengths. Tack sharpness remains impressive edge-to-edge in my testing, with minimal chromatic aberration or distortion thanks to top-tier optics Sony designed specifically for this camera’s sensor.

Macro focusing capabilities in the RX10 are excellent, allowing focusing distances less than 1 cm at wide-angle, translating into detailed close-ups with beautiful background separation. The FH3 supports macro focusing down to about 5 cm, adequate for casual flower or object shots but lacking professional finesse.

Stabilization is optical in both cameras, but the RX10’s system is more effective due to sensor-shift and lens-based corrections working in tandem, allowing handheld shooting at slower shutter speeds without blur - a marked advantage when shooting telephoto or macro in tricky light.

Burst Shooting and Performance: Quick Draw vs Leisurely Snap

When shooting action, frame rate and buffer depth matter tremendously. The RX10’s 10 fps burst mode with continuous AF allows capturing rapid sequences suitable for sports and wildlife photographers. Its quick buffer handling and responsive menus keep the experience fluid during extended shooting sessions.

In contrast, the FH3 offers only 6 fps burst mode and single AF locking per shot, which affects the ability to follow unpredictable subjects dynamically. Buffer size is limited, and lag between shots extends when shooting in high-quality JPEGs, causing tension when trying to seize fleeting moments.

For professional or serious enthusiast work involving fast-moving subjects or decisive moments, the RX10 is clearly the camera to rely upon.

Video Capabilities: From Modest HD to Pro-Grade Full HD

Video is another vital consideration. The FH3 outputs up to 1280x720 HD video at 30 fps using Motion JPEG encoding - a format known for large files and lower compression efficiency, often limiting recording times and producing lower-quality footage.

Sony RX10 advances video recording to full 1080p HD at 60p, 60i, and 24p frame rates with MPEG-4 and AVCHD codecs. The inclusion of a microphone input and headphone jack provides audio input and monitoring options far beyond the FH3’s barebones approach. Optical image stabilization also improves handheld video smoothness on the RX10.

While neither camera supports 4K video or advanced photo modes like 4K photo or post-focus, the RX10's video subsystem meets or exceeds the needs of most enthusiasts and even some pros requiring high-quality Full HD footage in a single, all-in-one device.

Connectivity, Power, and Storage: Modern Convenience vs Basic Essentials

Wireless features are notably absent in the FH3, which lacks Bluetooth, Wi-Fi, NFC, or GPS. Transferring files requires wired USB 2.0 connection, a slow proposition by today’s standards. The battery life is unspecified but relatively modest given compact category norms and a small battery.

Sony’s RX10 from 2014 introduces built-in Wi-Fi with NFC for instant pairings with smartphones, enabling remote control and convenient image sharing - a big plus for social shooters and professionals alike. Battery performance rates at roughly 420 shots per charge, sufficient for a day of varied shooting. The battery also uses a bigger, higher-capacity pack (NP-FW50), giving longer operational span than typical smaller compacts.

Both cameras support SD card storage, with the RX10 offering compatibility for Memory Stick formats as well. This flexibility benefits photographers who integrate Sony systems in their workflows.
