When it comes to small sensor compact cameras, two contenders that often draw attention among budget-conscious photographers are the Panasonic Lumix DMC-FH7 (FH7) and the Sony Cyber-shot DSC-G3 (G3). Both cameras are designed for casual use but bring distinct features to the table that influence the shooting experience, image quality, and versatility.

Having extensively tested compact cameras with similar sensor technologies, I’ll guide you through a comprehensive comparison covering technical details, real-world handling, and performance across a broad range of photography genres. This should help you make an informed decision based on your needs, whether you’re a beginner or a seasoned enthusiast looking for a portable second camera.

First Impressions: Size, Ergonomics, and Handling

Let’s start by examining physical size and ergonomics, essential factors for portability and comfort during long shooting sessions or street photography.

• Panasonic FH7: Extremely compact and pocket-friendly with dimensions of 95 x 56 x 19 mm and weighing just 126g. Its minimalist design implies easy one-hand operation, suited for quick snaps.

• Sony G3: Slightly larger and chunkier at 97 x 59 x 22 mm, weighing 185g. The extra heft gives a bit more presence in hand, which some photographers find adds stability.

From an ergonomics perspective, both lack a dedicated viewfinder, relying exclusively on their LCDs for framing. The FH7’s slim profile is ideal for travel and street use where discretion matters. The G3 offers a marginally larger grip area, which may be more comfortable for prolonged shooting, especially with its slightly longer focal range lens.

Control Layout and Interface: How Intuitive Are These Cameras?

Ease of access to controls defines how quickly you can react to changing scenes.

• The FH7 features a simple button layout with a touchscreen-enabled 3-inch display, though screen resolution is quite low at 230k dots. The touchscreen aids in quick focusing and menu navigation, despite the resolution limiting image preview fidelity.

• The G3 offers a larger 3.5-inch touchscreen with a notably higher resolution of 921k dots. This means clearer previews and smoother touch responsiveness for operations like zooming and setting the focus point.

Neither model includes a traditional viewfinder or advanced manual controls such as aperture priority or shutter speed priority modes. Both rely on automatic exposure and limited user input, making them best suited for casual photographers or entry-level users.

Sensor Technology and Image Quality: Where Pixel Count Meets Performance

Both cameras use the popular 1/2.3” CCD sensor technology, standard in budget compacts, yet the details matter.

Feature	Panasonic FH7	Sony G3
Sensor Type	CCD	CCD
Sensor Size	1/2.3" (6.08 x 4.56 mm)	1/2.3" (6.17 x 4.55 mm)
Resolution	16 Megapixels	10 Megapixels
Max Native ISO	6400	3200
Anti-alias Filter	Yes	Yes
Maximum Resolution	4608 x 3456	3648 x 2736
ISO Range	100 - 6400	80 - 3200

The FH7 boasts a higher resolution sensor (16MP vs 10MP), which theoretically can capture more detail - particularly advantageous for landscape and portrait work where cropping or large prints are desired. However, higher megapixels on a small sensor can introduce more noise at elevated ISO levels.

The G3’s max native ISO is capped at 3200, while the FH7 goes up to 6400, though practical usability of these ISOs is limited. Both cameras, using CCD sensors from older generations, tend to produce noise earlier than modern CMOS sensors, so you’ll want to keep ISO low for best image quality.

Autofocus and Shooting Speeds: Locking Focus in the Moment

For many photographers - especially those shooting wildlife, sports, or street scenes - autofocus speed and accuracy are vital.

Autofocus Feature	Panasonic FH7	Sony G3
AF System	Contrast Detection	Contrast Detection
Number of AF Points	11	9
Face Detection	Yes	No
Continuous AF	Yes (tracking)	No
Continuous Shooting Rate	4 fps	2 fps

The FH7 benefits from face detection autofocus, which helps keep skin tones sharp during portraits - a strong advantage if you mostly shoot people. Its continuous autofocus with tracking can capture moderate movement better than the G3. The FH7 allows continuous bursts at 4 frames per second, doubling the G3’s 2 fps, which can be helpful in simple action shots.

The Sony G3’s autofocus is a bit more basic, offering single AF mode only without face detection or continuous tracking, which may limit performance in dynamic scenes. However, its manual focus capability is a plus for macro and creative control - a feature the FH7 lacks.

LCD and Viewfinding Experience: Your Window to the World

Without an EVF, the LCD screen quality becomes your primary viewfinder.

• The Sony G3's 3.5-inch touchscreen with 921k dots clearly outperforms the FH7’s 3-inch 230k dot display, making composing and reviewing shots more comfortable, especially in brighter outdoor conditions.

• Both screens are fixed (non-articulating), so you must adjust your shooting posture for low or high angles.

For vloggers or travelers, the G3’s larger, crisper panel gives a better visual experience, although neither camera offers modern articulation or vari-angle screens.

Lens Comparison: Focal Range and Aperture

The fixed zoom lenses define the versatility for framing different subjects. Here’s how they compare:

Feature	Panasonic FH7	Sony G3
Focal Length (35mm eq)	28-112mm	35-140mm
Zoom Factor	4x	4x
Maximum Aperture	f/3.1 - f/6.5	f/3.5 - f/10.0
Macro Focus Range	5 cm	Not specified

The Panasonic FH7’s slightly wider start at 28mm is great for landscapes and environmental portraits, giving you more room indoors or tight spaces. While the FH7’s aperture starts brighter at f/3.1 compared to f/3.5 on the G3, both quickly narrow (down to f/6.5 and f/10 respectively) at telephoto lengths, limiting shallow depth-of-field and low light capabilities telephoto zoom.

The FH7’s close macro focus at 5 cm offers some macro shooting potential - good for flowers or food photography - whereas the G3’s lack of detailed macro specs suggests less emphasis here.

Image Stabilization and Low-Light Performance

Both cameras employ optical image stabilization, which is essential to counteract handshake, especially at telephoto zoom.

• The FH7’s optical IS is effective but limited by its small sensor noise characteristics.
• The G3 also provides optical stabilization but struggles beyond ISO 800.

Neither camera excels for shooting in low light or night photography given their older sensors and narrow maximum apertures. Long exposures must rely on steady hands or tripods.

Video Capabilities: Basic but Serviceable

If video is part of your creative workflow, here’s how they stack up:

Feature	Panasonic FH7	Sony G3
Max Video Resolution	1280x720 at 30fps	640x480 at 30fps
