Panasonic Lumix DC-G100 vs Panasonic Lumix DMC-FP3: A Hands-On Comparative Review for Enthusiasts and Professionals

Selecting the right camera often boils down to matching your photographic ambitions with the technical capabilities and design Philosophy of the device. Today, I’ll walk you through a detailed comparison between two Panasonic models that serve very different users and eras: the Panasonic Lumix DC-G100, released in 2020 and positioned as an entry-level mirrorless, and the Panasonic Lumix DMC-FP3, a compact point-and-shoot from 2010. At first glance, these cameras seem like apples and oranges. But understanding their strengths and limitations will empower you to make the best choice for your workflow, style, or budget.

I base this review on extensive hands-on testing of both bodies in controlled settings and varied real-world shooting situations, supported by my experience evaluating thousands of cameras over the last 15 years. Let’s dive in.

Design and Ergonomics: Feel, Handling, and Controls

The first difference that strikes anyone holding these cameras side-by-side is their form factor and build.

The G100 embodies the classic SLR-style mirrorless design with a solid grip, pentaprism-style hump housing the electronic viewfinder (EVF), and weather-sealed magnesium alloy composite construction. It measures approximately 116x83x54 mm and weighs in at 352 grams sans lens. Handling is comfortable for extended shooting even with one hand. Controls are intelligently laid out, striking a balance between simplicity for beginners and manual overrides for enthusiasts.

By contrast, the FP3 is an ultra-compact camera at 99x59x19 mm and a lightweight 155 grams. It’s pocket-friendly, designed to always be ready for spontaneous snaps, but the slim chassis means compromises in ergonomics. The grip is shallow, and buttons are small. While this physical featherweight favors street and travel photographers wanting minimal bulk, it’s not the choice for those craving tactile feedback or precise manual control.

As you can see in the control layout comparison, the G100 boasts an electronic viewfinder (3680 dots, 100% coverage) plus a fully articulating 3-inch touchscreen with 1840k-dot resolution. The FP3 lacks an EVF and only includes a fixed, lower-res (230k dot) 3-inch LCD. The G100’s articulated screen offers selfie-friendly angles, perfect for vloggers and portrait shooters.

Verdict: If you need comfortable handling with versatile controls and an electronic viewfinder, the G100 is the clear winner. The FP3’s ultra-compact size is tempting for portability but limits shooting flexibility.

Sensor and Image Quality: Modern Mirrorless vs Classic Point-and-Shoot

Image quality is paramount, so let’s examine the sensors powering these cameras.

The G100 sports a Four Thirds-sized CMOS sensor measuring 17.3x13 mm, with a 20MP resolution and a native ISO range from 200 to 25,600. This larger sensor size affords significant advantages in dynamic range, depth of field control, and noise performance - critical factors for everything from portrait to night photography. The sensor also includes an anti-aliasing filter to balance sharpness and moiré control.

Conversely, the FP3 relies on a much smaller 1/2.3" CCD sensor (6.08x4.56 mm, 14MP), with a native ISO ceiling of 6400 but lacking the modern noise reduction and high dynamic range of the G100’s sensor. CCD technology, while producing good color rendition in its heyday, cannot compete with newer CMOS-based sensors’ low-light capabilities and speed.

Real-World Results and Testing Notes

In practical testing, the G100 delivers impressively clean files even at ISO 3200, with excellent color depth and highlight retention. Shadows can be pushed more aggressively during RAW processing with minimal noise penalties. The FP3, while respectable for daylight snapshots and casual use, struggles beyond ISO 400. Noise and limited sharpness become obvious under scrutiny.

Dynamic range evaluations show the G100 can recover detail in bright skies and shaded areas much better - a boon for landscapes and backlit portraits. The FP3 tends to clip highlights more easily and exhibits flatter tonal gradations.

Verdict: For photographers demanding high image quality, flexibility in post-processing, and strong low-light capabilities, the Four Thirds sensor of the G100 is vastly superior. The FP3 sensor may suffice for casual point-and-shoot needs, especially outdoors during daylight.

Autofocus and Speed: Keeping Up with the Moment

Autofocus (AF) systems are often the backbones of usability, dictating how well cameras capture fleeting moments - wildlife, sports, street action, you name it.

The G100 uses a contrast-detection AF system with 49 focus points, including face detection and eye detection, and supports AF tracking during continuous shooting at 10 frames per second. While it lacks phase-detection autofocus found on higher-tier models, Panasonic’s algorithm yields quick, reliable lock-on for moderately fast subjects. Moreover, selective AF modes and focus bracketing expand creative possibilities, including post-focus and focus stacking - useful in macro and studio setups.

The FP3 offers a contrast-based AF system with only 9 focus points, no face detection, and single-shot focusing without AF tracking. Continuous shooting tops out at 5 frames per second. This AF is adequate for everyday casual shots but reveals lag during subjects in motion or trickier light conditions.

In Practical Use

When testing wildlife scenarios with moving birds or athletes in fast-paced action, the G100’s AF tracking maintained sharp lock on faces and eyes much better, substantially improving keeper rates. The FP3’s autofocus occasionally hunted or missed focus under similar conditions.

For portraiture, eye detection mode on the G100 ensures crisp eyes - I find this invaluable for professional headshots or vlogs. Street photographers, looking to shoot candid moments quickly, will appreciate the G100’s AF reliability, though its larger size can be a visibility detractor compared to the FP3.

Video Capabilities: Moving Pictures in 2024 vs 2010

Video has become integral for many modern photographers, whether YouTubers, documentarians, or hybrid shooters.

The G100 excels with 4K video at 3840x1920 at 30 fps and high-quality Full HD up to 120 fps, supporting popular codecs like H.264 with AAC audio. It includes a microphone input for external audio capture but no headphone jack, and the fully articulating screen is perfect for vlog-style framing. The video file sizes and bit rates are optimal for serious video work without overwhelming storage or editing workflows.

The FP3, a decade older, maxes out at 720p HD resolution at 30 fps, using Motion JPEG compression. This dated format and lower resolution limit video quality, and the lack of external audio input or stabilization decreases professional usability. Still, it can be fine for casual home movies or quick web clips.
