Panasonic Lumix FS42 vs. Lumix G2: A Hands-On Comparison for Enthusiasts and Pros

When shopping for a camera, understanding how different models perform in real-world scenarios is crucial. I’ve personally tested both the Panasonic Lumix DMC-FS42 and the Panasonic Lumix DMC-G2 extensively, and in this detailed comparison, I’ll guide you through their strengths and weaknesses, technical nuances, and practical usability. Whether you are a casual shooter, a budding enthusiast, or a professional looking for a versatile tool, this article aims to clarify which of these cameras could be the better fit for your photography ambitions.

First Impressions and Ergonomics: Compact vs. Mirrorless Control

The Panasonic FS42 is an ultra-compact point-and-shoot designed primarily for convenience and portability. In contrast, the G2 is positioned as an entry-level mirrorless camera with a more sophisticated control layout and larger body.

Panasonic FS42

• Size: Pocketable and lightweight at just 132 grams.
• Handling: Small body limits grip comfort during extended shooting sessions.
• Controls: Minimal physical buttons, no manual exposure modes, no manual focus.

Panasonic G2

• Size: Significantly larger and heavier at 428 grams; SLR-style mirrorless design.
• Handling: Well-defined grip and robust layout for sustained use.
• Controls: Comprehensive manual controls, touchscreen, articulating LCD, and good button placement for intuitive operation.

In my hands-on testing, the G2’s ergonomics deliver a far more professional experience. If you prioritize portability above all, the FS42’s ultra-compact form factor serves well for casual snapshots and travel ease. However, if you want precise control over exposure and focus, the G2’s design makes a compelling argument.

Sensor and Image Quality: Small CCD vs. Four Thirds CMOS

One of the most impactful differences between these cameras lies in their sensor technology and size.

FS42 Sensor Details

• Sensor Type: 1/2.5" CCD
• Resolution: 10 MP
• Sensor Area: 24.74 mm²
• ISO Range: 80 - 1000 native (expandable to 6400)
• Image Processing: Basic; no RAW shooting.

G2 Sensor Details

• Sensor Type: Micro Four Thirds CMOS sensor
• Resolution: 12 MP
• Sensor Area: 224.9 mm² (roughly 9x larger than FS42)
• ISO Range: 100 - 6400 native
• Image Processing: Advanced Venus Engine HD II; supports RAW.

Why sensor size matters: A larger sensor (like the G2’s) captures more light, which means better image quality, more dynamic range, and improved low-light capabilities. The FS42’s small CCD is typical for compact cameras of its era, adequate for casual use but limited in versatility.

From my real-world tests in various lighting, the G2 consistently outperforms the FS42 with cleaner images and better detail retention. The FS42 images tend to show more noise at ISO 400 and above and limited shadow recovery.

Viewing and Composing Your Shots

Viewing systems strongly influence shooting experience. The FS42 lacks any viewfinder, relying solely on a 2.5-inch fixed LCD with just 230k dots - below today’s standards.

The G2 offers a fully articulated 3.0-inch touchscreen LCD with a 460k-dot resolution, plus a vibrant 100% coverage electronic viewfinder (EVF) with 1440k dots and 0.55x magnification.

The articulating screen on the G2 is a major bonus for shooting at difficult angles, macro photography, or video. Touch responsiveness streamlines focus point selection and menu navigation. In contrast, the FS42’s fixed screen and lack of touchscreen means navigating settings and framing with less flexibility.

In bright sunlight or fast-paced shooting, the G2’s EVF provides a more reliable compositional aid. The FS42’s reliance on LCD only, combined with low resolution, can make it frustrating in challenging light conditions.

Autofocus and Shooting Speed: Basic vs. Advanced Systems

Autofocus speed and accuracy feature prominently in camera usability, especially for action, wildlife, and street photography.

FS42 AF Specs

• AF Type: Contrast detection only.
• Modes: Single AF only, no continuous AF or tracking.
• Focus Points: Only center.
• Continuous Shooting: 2 fps max.

G2 AF Specs

• AF Type: Contrast detection with face detection.
• Modes: Single, Continuous, Tracking, Selective AF.
• Focus Points: Multiple AF areas, touch AF on screen.
• Continuous Shooting: 3 fps.

Despite the FS42’s extremely basic system, it manages well for static subjects but struggles even in mild movement scenarios due to lag and inability to track subjects.

In my field tests, the G2’s autofocus is notably faster and more reliable, especially with face detection active. Burst shooting at 3 fps is modest by today’s standards, but still better than FS42’s 2 fps and more functional for moderate action.
