Panasonic FX78 vs Sony G3: Compact Camera Showdown for the Budget-Conscious Photographer

When you’re hunting for a compact camera that balances both affordability and reasonable image quality, the market can feel a bit like a jungle gym of confusing specs and unpronounceable acronyms. I’ve spent well over a decade digging into cameras of all shapes and sizes, and these two - the Panasonic Lumix DMC-FX78 and the Sony Cyber-shot DSC-G3 - stand out as interesting contenders in the small sensor compact category for photographers looking to step up from their phone cameras without spending a fortune.

In this deep-dive comparison, I’ll share my hands-on experience, testing insights, and clear-cut recommendations to help you decide which suits your style, budget, and photographic ambitions. Whether you’re a street shooter, vacation memory maker, or hobbyist portrait artist, this guide has something to help.

Let’s dive into the nitty-gritty.

Getting a Grip: Size, Feel, and Control Layout

At first glance, both the Panasonic FX78 and Sony G3 are classic compact cameras - you can stash them in almost any pocket. However, ergonomics and the physical design always matter, especially if you plan prolonged shooting sessions.

Panasonic FX78

• Dimensions: 100 x 55 x 21 mm
• Weight: 142 g
• Slim and lightweight, making it comfortable to slip in a jacket pocket or small bag
• Rounded edges lend to a cozy grip, although the thin body could challenge those with bigger hands

Sony G3

• Dimensions: 97 x 59 x 22 mm
• Weight: 185 g
• Slightly chunkier and heavier than the FX78, which provides a bit more heft and confidence when holding it steady
• The increased thickness adds a touch more comfort when resting in your hands, especially if you’re into shooting with a firmer grip

The Panasonic edges out the Sony for pure portability and weight, but the Sony’s form is arguably better suited for extended handheld use because of its slightly more substantial body.

First Impressions Matter: Top-View and Control Layout

Nothing breaks the flow of creativity more than fumbling for the right button or menu option. I took a close look at how each camera’s controls stack up, since user interface can make or break the shooting experience - especially when time is of the essence.

The Panasonic FX78 goes for a straightforward approach with fewer physical controls, which aids simplicity but restricts direct manual intervention. Its lack of dedicated manual focus or exposure controls may frustrate photographers who crave more hands-on fiddling. However, the FX78 compensates by incorporating a touchscreen that responds well and speeds up menu navigation.

The Sony G3, while also minimalist, offers manual focus, which I find invaluable for macro and creative shooting. Its buttons feel slightly more tactile, with a quicker physical zoom rocker and dedicated playback button. The downside? The absence of any manual aperture or shutter priority modes is a limitation either way.

In this matchup, if you want more tactile feedback and manual focus flexibility, the Sony wins. But if quick touchscreen operation and streamlined controls appeal, the Panasonic could be your cup of tea.

Sensor and Image Quality: The Heart of the Matter

Now, for what many consider the camera’s soul - the sensor. Both cameras pack a 1/2.3 inch CCD sensor, meaning smaller sensor size compared to DSLRs or mirrorless beasts, but ease of use and compactness.

Panasonic FX78

• Resolution: 12 MP (4000 x 3000 pixels)
• Sensor area: ~27.72 mm²
• Max native ISO: 6400
• Processor: Venus Engine FHD
• Anti-aliasing filter present to reduce moiré patterns

Sony G3

• Resolution: 10 MP (3648 x 2736 pixels)
• Sensor area: ~28.07 mm²
• Max native ISO: 3200
• Processor: undisclosed

From my detailed sensor testing protocol, which involves shooting standard test charts under controlled lighting and various ISO settings, the Panasonic FX78 edges out Sony in resolution and dynamic range. Its 12 MP sensor yields crisper details, which are particularly noticeable in landscape and macro shots. The Venus Engine FHD processor handles noise suppression fairly well up to ISO 800 and produces pleasing colors, albeit with the typical CCD signature of slightly warmer tones.

The Sony G3’s sensor, while similar in size, has a lower maximum ISO, constraining its low-light usefulness. Images can become softer at higher ISOs, and noise becomes more pronounced after ISO 400. However, the G3 maintains a nice color balance and decent exposure latitude in well-lit conditions.

Bottom line: For sharper images, better high-ISO performance, and more flexibility in post-processing, Panasonic has the advantage.

Live View and LCD Screen: How You See Your Shot Matters

Many casual photographers rely heavily on the rear display for composing shots, so screen quality and usability deserve scrutiny. Both cameras feature a 3.5-inch fixed LCD screen, but how they compare in resolution and readability makes a difference, especially outdoors.

The Sony G3 boasts a significantly higher-resolution screen - 921k dots versus the Panasonic’s modest 230k dots. This translates to a much clearer and sharper display when framing your shots, reviewing photos, or navigating menus. In bright sunlight, the higher pixel density and better contrast of the Sony’s screen consistently beat the Panasonic’s dimmer, lower-res screen.

The Panasonic employs a touchscreen, giving it an edge in menu navigation speed and touch focusing, an unexpected bonus for such an affordable compact. The Sony’s lack of touchscreen functionality means you’ll rely solely on physical buttons.

My advice? If you rely on the LCD for precise focusing, exposure confirmation, or prefer touchscreen control, lean Panasonic. If you prize sharp display quality and don’t mind button-driven menus, the Sony’s screen wins.

Autofocus Performance: Speed and Accuracy in Real World Use

Autofocus is often the Achilles heel in compact cameras, especially with small sensors and contrast-detection systems.

Panasonic FX78

• Contrast-detection AF with 11 focus points
• Single, continuous, and tracking autofocus available

Sony G3

• Contrast-detection AF with 9 focus points
• Single AF only; no continuous or tracking modes

From extensive hands-on testing involving moving subjects (walking people, cars, pets), the Panasonic FX78 consistently outperformed Sony’s G3 in autofocus speed and reliability. The FX78's wider coverage and continuous tracking deliver significant advantages for casual street and wildlife shooting, reducing missed shots.

The Sony G3’s autofocus felt sluggish and sometimes hunted noticeably before locking. Its lack of continuous AF makes it less suited for action or unpredictable subjects.

Bottom line: Panasonic FX78 has a more responsive and versatile AF system, which offers better real-world usability.

Lens and Zoom: Flexibility Counts

Both cameras feature fixed lenses, but their focal ranges and maximum apertures influence their usefulness across genres.

Panasonic’s wider 24mm equivalent wide-angle is a big plus for landscapes, travel, and cramped interiors, giving you more compositional freedom. Its faster f/2.5 aperture at the wide end ensures brighter images and better shallow depth of field effects for portraits and low light.

Sony’s lens zooms in farther (140mm vs 120mm equivalent), which helps for tight framing of distant subjects but suffers from the extremely slow f/10 aperture at telephoto end, which strongly limits low-light performance and bokeh quality.

The Panasonic’s macro ability down to 5 cm is a genuine bonus if you enjoy close-up photography.

In practice, I found Panasonic’s lens more versatile and better suited for general snapping, while Sony leans more toward telephoto reach but compromises light gathering.

Flash and Low Light: What Happens When the Sun Goes Down?

For those shoot-in-the-dark moments or dim party rooms, flash performance and high-ISO capability can save the day.

Panasonic FX78

• Built-in flash range: 5.6 m
• Flash modes: Auto, On, Red-eye reduction, Slow Sync
• Max ISO: 6400 with reasonable noise control up to ISO 800-1600

Sony G3

• Built-in flash range: 4.3 m (Auto ISO)
• Flash modes: Auto, On, Red-eye, Slow Sync
• Max ISO: 3200, but noise kicks in harshly past ISO 400

The Panasonic’s superior flash range and higher ISO ceiling translate into more usable images indoors or at night without relying solely on flash. The optical image stabilization on both models helps reduce blur in low light, but Panasonic's better sensor-wide ISO headroom means more graceful noise handling.

I tested both in candlelit environments and found the FX78 captured far cleaner images - with better skin tones and less grain.

Video Capabilities: Can They Replace Your Handycam?

Video specs often get short shrift in point-and-shoot cameras, but both models provide some level of HD capture.

• Panasonic FX78: Full HD 1920x1080 at 60 fps, AVCHD and MPEG-4 formats
• Sony G3: VGA 640x480 at 30 fps, Motion JPEG format

No contest here - Panasonic takes the crown for video without question. The FX78’s Full HD 1080p at 60 frames per second is exceptionally smooth for this class and budget, delivering sharp, colorful footage suitable for casual vlogging, family events, or content sharing. The AVCHD compression format helps maintain quality while keeping file sizes manageable.

Sony’s G3 only records low-res VGA video, which feels very dated and generally only suitable for tiny clips or fun experiments.

Bonus point to Panasonic for this category.

Battery Life and Storage: How Long and How Much?

A camera that dies after 200 shots will leave you scrambling, and storage options matter for workflow practicality.

Panasonic FX78

• Battery life: Approx. 200 shots per charge
• Storage: SD/SDHC/SDXC card compatible, internal storage available

Sony G3

• Battery life: No official figure cited; in my tests roughly equivalent or slightly less than Panasonic
• Storage: Memory Stick Duo/Pro Duo, internal storage

Here, Panasonic’s use of universally available SD cards is a big advantage over Sony’s proprietary Memory Stick format, which remains less common and more expensive. For any serious shooting, having cheap, high-capacity SD cards available is a must.

Battery life is modest for both - typical for these small compacts - so carrying a spare or charging frequently is wise.
