Both cameras heralded new mirrorless designs in their era and remain relevant in understanding early mirrorless technology evolution.

We’ve personally handled and tested thousands of cameras over the years, including these two classics, so in this detailed comparison, we’ll unpack everything you want to know about these cameras - from sensor sizes and autofocus capabilities to ergonomics and real-world shooting scenarios. Our goal? Help you figure out which system is better aligned with your creative ambitions, photography style, and budget.

Let’s get started.

Size, Build, and Handling: Feel the Difference

Before you even snap a shot, how a camera feels in your hands and how intuitive the controls are makes a world of difference.

• Panasonic G1: It embraces a classic SLR-style mirrorless design with a pronounced grip and well-spaced buttons. Despite its age, it feels robust for an entry-level camera weighing around 360 grams. Its fully articulated 3-inch screen with modest 460k dots resolution helps with framing at challenging angles, particularly when shooting low or high. The presence of an electronic viewfinder (EVF) covering 100% of the scene provides a camera-like experience akin to DSLR users but in a compact body.

• Sony NEX-C3: Sony took a different path here. The NEX-C3 features a rangefinder-style, more minimalistic body that is notably lighter at 225 grams and more compact (110x60x33 mm). The camera lacks an EVF, instead relying solely on a bright, 3-inch tilting LCD with an excellent 920k dots resolution. This gives the NEX-C3 an attractive size-to-screen quality ratio, making it ideal for those prioritizing portability.

In-hand, the G1 feels more secure for longer handheld sessions or with larger lenses, while the NEX-C3 favors discreet shooting and spontaneous street photography. Neither camera has advanced environmental sealing, so consider weather and dust protection carefully if you shoot outdoors often.

Sensor Technology and Image Quality: More Than Megapixels

Sensor technology is the heart of any camera. It determines not only your image resolution but also dynamic range, noise performance, and color fidelity.

The larger APS-C sensor in the NEX-C3 naturally provides better image quality potential. It captures more light, resulting in cleaner images at higher ISO values, which is crucial if you shoot in low light or require the flexibility for night and indoor photography.

Dynamic range is also notably higher on the Sony, allowing you to retain more detail in highlights and shadows. The G1’s Four Thirds sensor, while smaller, still delivers good results - fine for daylight and moderately controlled environments. Its 12MP resolution is respectable, providing acceptable prints up to A3 sizes but can lag behind the NEX-C3’s 16MP advantage, which offers more cropping and detail extraction capability.

Color depth and tonal gradation feel more natural on the NEX-C3, a bonus for portrait and landscape photographers looking for subtlety in skin tones and sky gradients.

Autofocus Performance in Real-World Situations

Let’s talk focus: the speed and precision of autofocus (AF) can make or break moments, especially in sports, wildlife, or street environments.

• Panasonic G1 relies on contrast-detection AF only, with 3 continuous fps shooting and basic multi-area focusing. It lacks face, eye, or animal detection autofocus, and does not offer AF tracking. This means while the system works well in ample light and controlled scenes, it can slow down or “hunt” in tricky focus conditions, such as moving subjects or low contrast scenarios.

• Sony NEX-C3 also uses contrast-detection AF but improves responsiveness with 25 focus points, more focus area flexibility, and support for AF bracketing and white balance bracketing - a useful bonus. Though the NEX-C3 lacks phase-detection AF and face detection (somewhat expected for its era), its autofocus system feels quicker and more confident than the G1’s for tracking moving subjects.

For wildlife or sports enthusiasts, neither camera is ideal by today’s standards, but the NEX-C3 offers noticeably better tracking and faster burst rates, doubling the G1’s 3fps limit.

Design and Control Layout: How Intuitive Is Your Workflow?

Shooting proficiency depends heavily on how well you can access key settings quickly and confidently.

• Panasonic G1’s SLR-inspired layout gives you dedicated dials for shutter speed, exposure compensation, and an electronic viewfinder. Its fully-articulated screen supports creative compositions. However, the button labeling and menu systems feel a little dated and can present a learning curve for newcomers.

• Sony NEX-C3 adopts a more minimalist control scheme with a tilt-angle LCD that helps with overhead or low shooting. The absence of an EVF saves weight but demands reliance on the screen in bright daylight, which can be challenging. The menus are straightforward, and the 25 AF points help you focus and recompose quickly.

The G1's deeper grip and button arrangement suit photographers who want more manual control and an EVF experience, while the NEX-C3 aims for simplicity and compactness.

Viewing and Image Review: The Display Matter

Your LCD screen or viewfinder is your window to framing and reviewing images.

• Panasonic’s fully articulated 3-inch LCD (460k dots) means you can rotate the screen to almost any angle, ideal for video shooters and macro enthusiasts. Despite modest resolution, it suffices for most framing and reviewing needs.

• Sony’s tilting 3-inch TFT Xtra Fine LCD at 920k dots doubles the resolution, delivering crisper image previews and menu readability. Unfortunately, it does not articulate fully, limiting extreme angle shooting. No EVF means you always operate via LCD, which may be less convenient outdoors.

For vloggers or heavy video users, the articulation on the G1 may be a bigger draw. For photographers who prioritize sharp, clear previews, Sony excels in LCD resolution quality.

Lens Ecosystem and Compatibility: Craft Your Vision

Choosing your camera is only half the story; the lenses you invest in often dictate the system’s long-term usefulness.

• Panasonic G1 uses the Micro Four Thirds mount, which is extensively supported. Today, you have access to over 100 lenses ranging from ultra-wide to super-telephoto, including third-party options from Sigma, Tamron, and more. The smaller sensor means a 2.1x crop factor, which influences focal length equivalents - a standard 25mm lens frames like a 50mm on full frame.

• Sony NEX-C3 adopts the Sony E-mount, introduced with the NEX series, quickly growing into a strong system with about 120 lenses available at varying price points. The APS-C crop factor is 1.5x, which is less aggressive than the G1, preserving wider angle perspectives.

Both mounts support manual focusing lenses well, but Sony's E-mount offers better integration with modern autofocus lenses and more options from major manufacturers and fast primes.

Battery Life and Storage: Keep Shooting Longer

• The Panasonic G1 offers approximately 330 shots per full battery charge using the Li-Ion battery pack. This is typical for cameras of its class but warrants spare batteries for extended shoots.

• The Sony NEX-C3 pushes the number higher with about 400 shots per charge, giving it an edge for travel and event photographers needing more uptime.

Both cameras use a single SD card slot, and the NEX-C3 crafts increased versatility with additional Memory Stick support.

Video Capabilities: Basic, But Practical

If you’re considering hybrid use for photo and video, here’s what each camera offers:

• The Panasonic G1 does not support video recording, restricting its multifunctional use scenario. This can be limiting if you want to mix stills and video, especially in this era where mirrorless cameras’ video capabilities are expected.

• The Sony NEX-C3 supports 720p HD video at 30fps with MPEG-4 format. Although basic by today’s standards, the quality and ease of use make it a good entry point for casual video creators and vloggers, especially when paired with interchangeable lenses and accessory microphones (note: no dedicated mic input).
