Your first interaction with a camera sets the tone of your user experience for months or years. Both the Panasonic G10 and Sony NEX-3 have distinctive designs with unique ergonomics aimed at beginner photographers stepping into mirrorless systems.

Physical Comparison & Ergonomics

The Panasonic G10 sports a more traditional SLR-style body with a pronounced grip. Its dimensions are 124×90×74 mm conserving a feel closer to DSLRs, weighing 388 grams. This makes it more robust and easier to handle for photographers transitioning from DSLRs accustomed to a solid grip and viewfinder.

The Sony NEX-3 adopts a rangefinder-inspired compact design, measuring 117×62×33 mm and weighing just 297 grams - making it one of the lightest cameras in its category at launch. This ultra-portability benefits street and travel photographers who prioritize discretion and minimal bulk.

Insights:

• Panasonic G10: Better for photographers wanting DSLR ergonomics and grip confidence.
• Sony NEX-3: Appeals to those valuing compactness and ease of carry with a sleek design.

Top Controls and User Interface: Let's Talk Controls

How a camera feels in your hands when adjusting settings affects your shooting rhythm - vital in fast-paced scenarios like sports or street photography.

The G10’s top panel deploys dedicated mode dials and buttons with tactile responsiveness. The familiar layout supports quick access to shutter speeds, exposure compensation, and flash controls. Control placement feels mature for its class, supporting both novice learning and quicker adjustments by advanced users.

Sony NEX-3, conversely, streamlines controls to achieve its compact profile. It offers fewer physical buttons and relies more on the rear LCD interface. While sleek, this can slow down setting changes if you prefer manual control. The NEX-3 lacks a viewfinder, focusing all framing and exposure work on the screen.

Sensor and Image Quality: The Heart of the Matter

Image quality stems directly from sensor size, resolution, and image processing. Let’s compare the sensors and evaluate real-world impacts.

Sensor Specs at a Glance

Sony’s APS-C sensor size advantage yields better dynamic range, deeper color depth, and improved noise handling at higher ISOs. These translate to better image quality in landscapes and low-light environments, critical for all disciplines requiring detail and tonal range.

Panasonic’s smaller Four Thirds sensor sacrifices some low light prowess but benefits from a 2.1x crop factor, enabling more reach with telephoto lenses - a plus for wildlife and sports with budget lenses.

Real-World Observations:

• Sony’s images generally show superior shadow detail retention and cleaner high ISO results.
• Panasonic’s output is respectable with vibrant color but can show more noise in dim conditions.

LCD and Viewfinder: Framing Your Shots

The LCD and viewfinder are your primary framing tools - let’s see how these cameras compare in practice.

Display Characteristics

Panasonic’s electronic viewfinder provides a DSLR-style shooting experience, beneficial in bright settings where screens wash out. However, the relatively low EVF resolution makes it less detailed compared to modern standards. Sony lacks a viewfinder entirely, meaning you depend on the rear LCD - beneficial for video but not always ideal for stills under strong sunshine.

The NEX-3's tilting screen enables flexible shooting angles - useful in street or macro scenarios, or capturing spontaneous moments without distracting your subjects.

Autofocus Systems: Accuracy vs Speed

In our experience, autofocus (AF) systems often make or break shooting quality, especially outdoors and with moving subjects.

The NEX-3 incorporates 25 contrast-detect AF points, distributed to enable fairly flexible focusing options. Contrast detection, however, tends to be slower in continuous AF compared to phase-detection systems emerging at that time.

The G10 uses contrast detect AF with no detailed count of points, performing adequately for stationary subjects but slower on moving ones.

Our shooting tests revealed the NEX-3 is better suited for capturing moderately moving targets thanks to more AF points and faster burst rates (3 fps for G10 vs. 7 fps for NEX-3). However, both cameras lack phase-detect AF, limiting performance on fast action photography.

Performance Across Photography Disciplines

Understanding how these cameras perform in your favorite photography genres clarifies which model aligns with your style.

Portrait Photography

Skin tones and bokeh (background blur) define good portraits.

• Panasonic G10: The smaller sensor yields deeper depth-of-field at similar apertures, resulting in less subject separation. However, it offers face detection AF aiding sharp focus on eyes.
• Sony NEX-3: APS-C sensor enables softer backgrounds naturally. Face detection and multiple AF points contribute to sharp eye focus. Higher resolution benefits portrait detail.

Recommendation: Sony NEX-3 is superior for portraits due to its sensor advantage and focusing coverage.

Landscape Photography

Dynamic range and resolution are king, plus weather sealing is common in travel gear.

• Panasonic G10: Decent dynamic range but less than Sony. The body lacks any environmental sealing, meaning caution is needed.
• Sony NEX-3: Better dynamic range and 14 MP sensor give more detail when cropping. No weather sealing; both are sensitive in harsh weather.

High-resolution images and wide ISO latitude favor Sony for serious landscape work.

Wildlife and Sports Photography

Fast autofocus, burst rate, and reach define success here.

• Panasonic G10: 2.1x crop factor helps telephoto reach using affordable Four Thirds lenses. Burst rate of 3 fps is modest.
• Sony NEX-3: 7 fps burst rate doubles the Panasonic’s speed for capturing split-second action. 1.5x crop factor means slightly less reach but better sensor performance.

Autofocus speed is similar, but burst advantage gives Sony the edge.

Street Photography

You want a discreet and fast camera capable in low light.

• Panasonic G10: Bulkier and heavier, less discreet.
• Sony NEX-3: Compact, lightweight, with tilting screen to avoid raising camera to eye, perfect for candid shots.

Sony’s compactness wins here.
