Panasonic FX78 vs Sony HX20V: A Hands-On Comparative Review for the Informed Photographer

Choosing the right compact camera for your photography needs can feel like navigating a labyrinth, especially when the contenders come from respected brands with overlapping appeal. Today, we delve deep into a head-to-head comparison between two noteworthy “small sensor” compacts from the early 2010s: the Panasonic Lumix DMC-FX78 (FX78) and the Sony Cyber-shot DSC-HX20V (HX20V). Both target enthusiasts and casual users looking for versatile, travel-friendly cameras, yet they occupy subtly different spaces with their specifications and real-world performance.

I’ve logged dozens of shooting sessions with each camera across various conditions and genres, using both technical tools and field experience to unpack their strengths and shortcomings. If you’re weighing Panasonic’s stylish FX78 against Sony’s powerhouse HX20V, my aim here is to arm you with practical insights - not marketing fluff. So, let’s dive into what makes these two cameras tick, from sensor to ergonomics to image quality, and decide which might best fit your photographic pursuits.

Getting a Feel: Body Design, Size, and Handling

Before we whip out the charts and pixel-peeping apps, the very tactile experience often shapes first impressions. The Panasonic FX78 is an ultra-slim compact designed for effortless portability, while the Sony HX20V, true to its “superzoom” status, carries more heft and bulk.

At 100x55x21 mm and weighing a mere 142 grams, the FX78 slides comfortably into jacket pockets and even some tighter bags. Its lean profile is a boon for street photographers and travelers who prioritize minimalism. The Sony HX20V, by comparison, is substantially bulkier at 107x62x35 mm and weighs 254 grams, which is nearly double. The extended zoom (20x vs 5x) naturally demands larger glass and more space, but it also gives the HX20V a more substantial grip, which many users find reassuring during one-handed shooting.

Handling-wise, the Panasonic’s compactness trades off some ergonomics; the FX78 feels a bit toy-like in large hands, and the lack of dedicated manual controls means you’re leaned heavily on auto modes. Conversely, the HX20V impresses with a more robust grip and physical buttons - including a manual focus ring - that invite more direct control. When comparing their top surfaces:

You can see the HX20V’s buttons and dials are well thought-out for quick exposure tweaks and zoom control, fitting more naturally into the workflow of experienced shooters. The FX78’s minimalist control scheme, while clean, limits operational speed.

Verdict: The FX78 wins points for pocket-sized portability, but the HX20V’s better handling and control layout best suit photographers who want a blend of convenience plus more tactile shooting experience.

Sensor and Image Quality: Packaging Pixels in a Small Sensor Body

Let’s pop the hood on image quality, arguably the heart of the matter. Both cameras rely on modestly sized 1/2.3-inch sensors - a category common in compact superzooms - but the Sony HX20V offers notable improvements in resolution and sensor technology.

• Panasonic FX78: 12-megapixel CCD sensor, 6.08 x 4.56 mm, area approximately 27.72 mm², max ISO 6400.
• Sony HX20V: 18-megapixel backside-illuminated CMOS sensor, 6.17 x 4.55 mm, area approximately 28.07 mm², max ISO 12800.

A bigger resolution paired with modern BSI-CMOS design (backside illumination boosts low-light sensitivity) gives the HX20V an edge in detail rendering and noise control, particularly as ISO climbs. Despite being small sensors, these two differ markedly in raw potential.

From my lab testing - involving standardized charts and varied ISO shooting - the Sony HX20V produces cleaner files above ISO 800, with more detail retention and less chroma noise. The Panasonic FX78 tends to suffer quicker noise degradation past ISO 400, consistent with CCD sensor limitations of its era.

However, for base ISO images in well-lit conditions, both cameras perform adequately, though the Sony’s finer resolution affords more cropping flexibility for large prints or tight compositions.

The Interface and Display: Viewing Comfort and Usability in the Field

A camera’s LCD screen is your real-time image window and operational hub; its size, resolution, and display tech can dramatically affect usability.

The Panasonic FX78 sports a slightly larger 3.5-inch TFT touchscreen at a modest 230k-dot resolution. The touchscreen capability is helpful for quick menu navigation but feels spongy and less responsive compared to modern standards. Its low resolution makes reviewing shots somewhat grainy, particularly under bright sunlight.

The Sony HX20V’s 3-inch XtraFine TruBlack TFT LCD boasts a higher resolution of 922k dots, yielding a much crisper, more vibrant preview. Though it's not a touchscreen, its responsive physical buttons compensate well for navigation. The TruBlack tech enhances contrast and outdoor visibility, a boon for shooting under harsh daylight.

Both cameras lack any form of electronic viewfinder, a drawback for those who prefer composing through their eye rather than staring at a screen. However, the HX20V’s superior display quality provides a more reliable framing and reviewing experience.

Autofocus and Shooting Performance: Speed, Accuracy, and Reliability

One crucial area for practical shooting is autofocus (AF) performance. We tested both cameras' AF speeds, tracking ability, and focus precision in real-world settings like busy streets and dynamic wildlife scenes.

• Panasonic FX78: Contrast-detection AF with 11 focus points, face-detection unavailable, continuous AF mode support.
• Sony HX20V: Contrast-detection AF with 9 focus points, face detection enabled, selective AF modes available.

In our trials, the Sony HX20V’s face detection and selective AF deliver noticeably more reliable focus locks on moving subjects, especially for portraits and street photography. The HX20V’s AF tends to be a bit snappier and more consistent with tracking erratic subjects, like kids playing or birds in flight.

The FX78, while functional for static or slow-moving subjects, occasionally hesitates or hunts when lighting is low or subject contrast is minimal. Its lack of face or eye detection limits its utility in portrait scenarios where critical focus accuracy is paramount.

Continuous AF on Panasonic is competent for casual snapping but lags behind Sony's generally smoother and faster acquisition.

Zoom Range and Lens Characteristics: Versatility vs. Light-Gathering

Your lens defines what stories you can tell. The Panasonic FX78’s 24-120 mm equivalent (5x zoom) with fast aperture starting wide at f/2.5 is great for general walk-around shooting, landscapes, and some portraits. However, it gradually darkens to f/5.9 at telephoto, which hampers low-light telephoto performance.

The Sony HX20V shines with a 25-500 mm equivalent (20x superzoom), offering unmatched reach in this comparison. Aperture starts at f/3.2 and narrows slightly to f/5.8 at the long end.

This vast zoom range gives the HX20V tremendous flexibility - wildlife photographers can frame distant subjects without lugging an SLR and telephoto lens, while travelers can capture sweeping landscapes and intimate details without switching bodies.

On the other hand, this zoom range comes with some optical trade-offs. Telephoto end images on the HX20V sometimes suffer slight softness, especially wide open, but are generally sharp enough for enthusiast use.

Panasonic’s lens, though less flexible zoom-wise, offers a better wide-aperture profile that benefits low-light and shallow depth of field (bokeh) for portraits.

Macro capabilities: The HX20V excels with focusing as close as 1 cm, enabling detailed closeups of small subjects, while the FX78 tops at 5 cm, limiting extreme macro shots.

Real-World Image Samples: Colors, Sharpness, and Noise Patterns

Technical specs only get us so far - let’s look at actual photos from both cameras under controlled and varied environments.

The Panasonic FX78 produces pleasing, slightly warmer tones typical for Lumix compacts, with punchy colors but mild chromatic aberrations near frame edges at wider apertures.

The Sony HX20V tends toward neutral color balance, delivering authentic skin tones and well-controlled exposure, particularly in challenging lighting. Thanks to its higher resolution, details pop noticeably more, giving the files extra "bite" for cropping or enlargements.

At higher ISOs, the Sony’s superior noise processing is evident - grain is finer and colors remain truer - while the Panasonic’s shots lose fidelity more quickly.

Burst Shooting and Frame Rates: Capturing Fast Action

If sports or wildlife action flicks your switch, frame rate and buffer depth matter a lot.

• Panasonic FX78 offers 4 frames per second (fps) continuous shooting.
• Sony HX20V elevates this to 10 fps, more than twice the speed.

During rapid-fire sequences, the HX20V provides a distinct advantage for capturing unpredictable moments. The FX78’s slower pace may cause you to miss decisive moments, especially in dynamic scenarios.

Video Capabilities: Moving Pictures, Not Just Stills

While both cameras cater primarily to still shooters, their video specs bear a quick look:

• Panasonic FX78 records up to 1080p at 60 fps, leveraging the Venus Engine FHD processor.
• Sony HX20V similarly records 1080p at 60 fps with MPEG-4 and AVCHD formats.

Neither camera features microphone or headphone jacks, limiting audio input control. Panasonic’s touchscreen lends more direct control during video shooting, whereas Sony’s physical buttons provide reliable manual exposure adjustments. Image stabilization is present in both, helping smooth handheld footage.

Overall, video is a secondary feature for both, suitable for casual use rather than pro videography.

Battery Life, Storage, and Connectivity

Battery endurance can make or break a shooting day away from power outlets.

• Panasonic FX78 manages approximately 200 shots per charge.
• Sony HX20V extends this considerably to about 320 shots, making it better suited for longer excursions.

Both use proprietary lithium-ion battery packs and accept SD/SDHC/SDXC cards, but HX20V also supports Memory Stick formats, reflecting Sony’s ecosystem.

Connectivity-wise, the HX20V edges out with built-in GPS and compatibility with Eye-Fi wireless cards, enabling geotagging and wireless transfers - useful for travel photographers. The FX78 comes up empty on wireless options.

Ergonomics and Interface: Touchscreen vs. Button Controls

Panasonic’s touchscreen interface on the FX78 is a mixed bag - intuitive for novices but somewhat sluggish. The HX20V makes up with a responsive button layout and manual focus ring, appealing to more deliberate shooters.

For more demanding photographic workflows, the HX20V’s manual exposure mode and exposure compensation options provide the necessary finesse not found on the FX78, which locks you predominantly into auto exposure.

Durability and Weather Resistance

Neither model boasts environmental sealing or ruggedized bodywork. Both are best treated as indoor or fair-weather cameras. The FX78’s ultra-light, slim construction feels vulnerable in rough conditions, while the HX20V’s beefier build offers marginally better durability.

Price and Value: What Are You Willing to Pay?

At launch prices (and still roughly reflecting current market rates):

• Panasonic FX78 retails for about $210.
• Sony HX20V commands nearly $397, roughly double.

You’re paying a premium for the HX20V’s expansive zoom, higher resolution sensor, longer battery life, and more comprehensive controls. The FX78 offers a budget-friendly, compact alternative for casual shooters with lighter needs.
