Panasonic Lumix DMC-FS42 vs Panasonic Lumix DMC-G10: A Practical Showdown Between Ultracompact Simplicity and Mirrorless Versatility

In the ever-evolving landscape of digital photography, the choice between an ultracompact camera and an entry-level mirrorless model often boils down to striking the right balance between portability and capability. Today, I’m diving deep into two Panasonic Lumix models that exemplify this contrast: the diminutive Panasonic FS42 and the more ambitious Panasonic G10. Having spent countless hours testing cameras, lenses, and shooting across genres, I’m eager to peel back the specs and real-world performance of these two distinctly different tools.

If you’re a photography enthusiast - or perhaps a pro looking for a capable second body - this comparison will dissect the strengths, weaknesses, and ideal use cases for each camera. And yes, lurking behind raw numbers, sensor sizes, and specs are the stories of what it’s like actually holding, shooting with, and living alongside these two cameras.

First Impressions and Size Matters: Pocket Friend or Versatile Companion?

Before even popping a memory card in, size and ergonomics make or break the relationship between you and your camera. The Panasonic FS42 is a textbook example of an ultracompact point-and-shoot: small, lightweight, and easy to chuck in a pocket or a tiny bag. The G10, true to its mirrorless SLR-ish heritage, commands a more substantial presence, fit for hands that appreciate a proper grip and physical controls.

At just 98x55x22mm and weighing a mere 132 grams, the FS42 is effortless to carry everywhere. Its appeal is instant for casual photographers, travel junkies wanting a backup cam, or anyone who despises lugging gear. That said, the FS42’s petite stature demands compromises in handling and button placement.

Conversely, the G10 weighs in at 388 grams with a 124x90x74mm footprint - noticeably chunkier but still very manageable, especially compared to DSLRs of its time. Quartz-fine lines, a substantial grip, and well-placed dials make it a comfortable companion for longer shooting stints. Ergonomically, it’s a clear step up if you value tactile control and a firm hold.

This size and ergonomics difference informs everything that follows: from lens interchangeability to shooting speed, and ultimately, creative potential.

Exploring the Controls: Button Bonanza or Minimalist Simplicity?

Having the right controls at your fingertips isn’t just about convenience; it’s about creative freedom. The FS42 keeps things minimal with basic shooting modes and little in the way of manual override. The G10, on the other hand, is the kind of camera that encourages you to tinker, tweak, and take full charge.

Take a peek at their top decks:

The FS42 features a straightforward layout with a simple mode dial and shutter button. It’s ideal for point-and-shoot users who want quick access but little else. No exposure compensation, no aperture priority, no manual shutter speed - just aim and press.

The G10 offers an SLR-style top plate, including dedicated dials for shutter speed, aperture, exposure compensation, and a flexible mode dial. For those who enjoy creative control, it’s a breath of fresh air compared to typical ultracompacts.

Bottom line: If you crave manual exposure or creative modes (shutter priority, aperture priority), the G10 wins hands-down. The FS42 aims squarely at simplicity and quick snapshots.

Sensor Technology and Image Quality: Size Isn’t Just About Bulk

Here we hit one of the fundamental differences between these two cameras: their sensor size, technology, and resulting image potential.

The FS42 uses a 1/2.5-inch CCD sensor measuring just under 25mm² with 10MP resolution. CCD sensors, while historically capable of high color fidelity, have limitations in low light and dynamic range. Their smaller size results in higher noise levels at ISO above base settings. The G10 features a much larger Four Thirds CMOS sensor measuring approximately 225 mm² and packing 12MP. This sensor type typically delivers better image quality, higher dynamic range, and improved low-light performance.

From my hands-on testing with both models:

• The G10’s sensor produces cleaner images with richer color depth thanks to its better DxO Mark color depth scores (21.2 vs. untested for the FS42) and dynamic range (~10.1 EV).
• ISO performance in the G10 is superior, with usable ISO 400 and above images, whereas the FS42 tops out ISO 1000 but is considerably noisy past ISO 400.
• Detail retention is markedly better on the G10, aided by higher native resolution (4000x3000 px vs 3648x2736) and lack of heavy noise reduction.

Put simply: the G10 is the serious choice for image quality, while the FS42 serves casual shooters satisfied with JPEGs from a compact sensor.

The Rear Interface: Viewing World Through LCDs

In live compositions and reviewing your shots, display quality is critical. The FS42 has a 2.5-inch fixed LCD with a low resolution of 230k dots - functional but limited in detail and brightness. The G10 ups the ante with a sharper 3-inch TFT LCD sporting 460k dots, providing greater clarity and color fidelity when framing and reviewing shots.

While neither are touchscreens or fully articulating, the G10’s larger screen and electronic viewfinder (EVF) with 202k dot resolution add a layer of versatility. The EVF coverage of 100% and 0.52x magnification offers eye-level composition - something the FS42 lacks entirely.

For me, the EVF is crucial when shooting in bright daylight or situations where the LCD’s visibility falters. It’s one reason the G10 feels more pro-grade despite being an entry-level mirrorless.

Autofocus Systems: Snappy or Sluggish?

Autofocus technology evolves rapidly, but even a decade ago, there was a significant gap between compact fixed-lens cameras and mirrorless interchangeable-lens models.

The FS42 relies on a contrast-detection AF system with a single focus mode. It’s slow, often hunting in low light, and neither face detection nor tracking AF is available. Meanwhile, the G10 features an enhanced contrast-detection system with multiple focus areas, face detection, continuous AF, and tracking capabilities.

Shooting a few fast-moving subjects side-by-side highlighted the difference: the G10 locks focus briskly, tracks subjects reliably, and provides more creative control through AF area selection. The FS42, on the other hand, is better suited for benign scenarios - static subjects, good light, and low expectations of speed.

Shutter and Burst Rates: Capturing the Action

Neither the FS42 nor the G10 will win speed awards in today’s high-performance arena, but there’s a clear contrast here as well.

• FS42: Max shutter speed 1/2000 sec, continuous shooting 2 FPS.
• G10: Max shutter speed 1/4000 sec, continuous shooting 3 FPS.

While these frame rates may seem low compared to professional sports cameras (some bust past 10 FPS effortlessly), the G10’s faster shutter and burst speed, combined with continuous AF, make it more usable for casual sports, kids, or wildlife photography.

Lens Ecosystem: Fixed or Flourishing?

One of the most significant considerations when choosing a camera system is the lens lineup. FS42’s fixed 33-132mm (35mm equivalent) f/2.8-5.9 lens simplifies choices but limits zoom reach, aperture flexibility, and creative optical control.

The G10, sporting the Micro Four Thirds mount, benefits from an extensive ecosystem of over 100 compatible lenses spanning ultra-wides, fast primes, macro lenses, and long telephotos. This diversity enables photographers to tailor their kit to specific genres - from macro closeups to wildlife telephotos.

For serious photographers (or those aspiring), the lens ecosystem advantage is a huge factor favoring the G10.

Versatility Across Photography Genres: Who Shines Where?

Let’s break down how each camera performs across major photography disciplines based on my practical testing and experience:

Portrait Photography

• FS42: The lack of manual aperture control and a small sensor means shallow depth of field and creamy bokeh are hard to achieve. Without face or eye detection AF, portraits risk being slightly soft or poorly focused.
• G10: With manual aperture, face detection, and access to fast primes, portraits are better controlled. Skin tones render more naturally due to better sensor color depth.

Landscape Photography

• FS42: Dynamic range is limited; shadows and highlights tend to clip quickly. The fixed lens’s moderate wide-angle coverage restricts framing options.
• G10: Larger sensor, RAW support, and manual controls allow more nuanced treatment of landscapes. The ability to bracket exposures helps tackle tricky lighting. Weather sealing is absent in both, though.

Wildlife Photography

• FS42: Limited zoom, slow AF, and low burst rate hamper capturing action or distant wildlife.
• G10: Faster AF, better burst mode, and a matched telephoto lens can help capture wildlife moments better, though still far from professional sports cameras.

Sports Photography

• FS42: Practically a no-go outside perfect scenarios.
• G10: While modest, the G10’s continuous AF and burst speed can capture casual sports scenes.

Street Photography

• FS42: Its small size makes it unobtrusive and easy to carry - great if you prioritize portability over control.
• G10: Larger and more conspicuous but offers better image quality and control. Shooting discreetly might require practice.

Macro Photography

• FS42: Macro focus as close as 5cm is nice for casual snaps but lacks focusing precision.
• G10: With dedicated macro lenses and better manual focus aids, macro photography is more rewarding.

Night and Astro Photography

• FS42: High noise at elevated ISOs, no long exposure modes.
• G10: With manual exposure modes, long shutter speeds, and better ISO performance, the G10 is more capable for night and star shooting.

Video Capabilities

• Both capture Motion JPEG video, but the G10’s max resolution is 1280x720 at 30 fps, compared to FS42’s 848x480 max. Neither offers advanced video features or stabilization, but the G10 supports HDMI output for more versatile monitoring.

Travel Photography

• FS42: Ultralight and pocketable - a no-brainer for travel convenience.
• G10: Bulkier but more versatile. Battery life is significantly better (380 shots vs unknown FS42 longevity), making it the better companion for intensive travel shoots.

Professional Work

• The FS42 is clearly not intended for professional workflows; no RAW, no manual exposure, limited image quality. The G10 offers RAW shooting, manual overrides, and better sensor performance - helpful for professional or serious amateur use.

Real-World Image Gallery: Seeing Is Believing

Numbers are one thing; real images tell the full story. Here’s a selection of photos shot under various conditions (portrait, landscape, macro, and low light) with each camera.
