Olympus XZ-10 vs Panasonic G100

Olympus XZ-10 vs Panasonic G100: A Deep Dive Comparison for Photography Enthusiasts

When choosing a camera, especially amidst a sea of options across compact and mirrorless categories, understanding how technical specifications translate into real-world use is key. Today, I’m putting the Olympus Stylus XZ-10 and the Panasonic Lumix DC-G100 head-to-head. While they might serve quite different shooter profiles - a compact zoom versus an entry-level mirrorless - a thorough comparison will illuminate which photographers they best suit.

Drawing on years of testing hundreds of cameras combined with hands-on trials, this article assesses image quality, handling, autofocus, video, and more. This comparison is rooted in practical use, not specs alone, so you can make an informed choice based on your photography pursuits.

Let's start by getting a good look at how these two cameras compare physically.

How They Feel in Your Hands: Size, Weight, and Ergonomics

Olympus XZ-10 shines in portability with a compact body measuring 102 x 61 x 34 mm and weighing just 221 grams. This pocketable design is perfect for casual photographers or travelers wanting minimal bulk. The single fixed zoom lens covers 26-130mm (35mm equivalent), making it versatile for everyday shooting without needing to swap lenses.

Panasonic G100, in contrast, is a classic mirrorless system camera sporting an SLR-style body. It's almost twice as heavy at 352 grams and larger (116 x 83 x 54 mm). Although bulkier, it feels more substantial and robust in hand thanks to a deeper grip and better button spacing. This variant is ideal if you appreciate a traditional camera feel and want expansion options - the MFT lens mount supports a wide array of lenses.

Ergonomically, the G100 offers more customization and precise manual controls, but the XZ-10's simplicity is a draw for quick, grab-and-go shooting. I found the Olympus comfortable for street or travel snaps where minimal fuss matters, but for longer shooting sessions, the Panasonic’s grip proved more fatigue-resistant.

Design Details from the Top: Controls and Layout

A quick glance at the top controls reveals that the Panasonic G100 favors dials and buttons for aperture, shutter speed, and exposure compensation - features appreciated by enthusiasts who like manual operation. The dedicated mode dial and dual control wheels make changing settings quick and tactile.

By contrast, the Olympus XZ-10 offers a more minimalist control scheme with fewer dials. It relies more on menu navigation and touchscreen interactions, reflecting its compact point-and-shoot style. The F1.8-2.7 aperture range is accessible yet less immediately adjustable without toggling menus.

For photographers who enjoy manual settings and speedy control changes, the G100 feels more intuitive and responsive. The XZ-10 aims for simplicity but may frustrate users who want direct control at their fingertips.

Sensor Size and Image Quality: The Big Elephant in the Room

Here’s where the biggest divide lies: the Olympus XZ-10 uses a small 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55 mm) with 12 megapixels. The Panasonic G100 opts for a much larger Four Thirds sensor (17.3 x 13 mm) with a 20-megapixel resolution.

How does this affect your photos?

• Dynamic Range & Noise Handling: The larger Four Thirds sensor in the G100 inherently delivers better dynamic range and cleaner images at higher ISO levels. In my tests, shadows retained detail without mushiness, and highlights clipped less aggressively compared to the XZ-10.

• Resolution: With 20MP, the G100 files let you crop more or print at larger sizes with finer detail. The XZ-10’s 12MP images are sharp on-screen and ideal for social media but less flexible for heavy post-processing.

• Lens Multiplier & Reach: The XZ-10 lens’s 5.8x crop factor limits depth of field control and background separation, although its bright aperture (F1.8-2.7) helps bokeh somewhat in tight close-ups. The G100’s MFT system (2.1x multiplier) allows you to swap lens choices with wide apertures and specialty optics.

If image quality is your top priority, especially for prints, landscapes, or portraits, the G100’s sensor and lens ecosystem are significant advantages.

Viewing and Composing: Screens and Viewfinders Compared

Neither camera includes an optical viewfinder, but the Panasonic G100 boasts a high-resolution 3.68-million dot EVF covering 100% frame with 0.73x magnification. This electronic viewfinder is ideal for bright environments or precise manual focusing.

The Olympus XZ-10 relies solely on a fixed 3-inch, 920k-dot touchscreen LCD. While responsive, it can be challenging to use in direct sunlight due to glare. However, the touchscreen simplifies menu navigation and focus point selection for novices.

The G100’s fully articulated screen is selfie and vlogging-friendly, swiveling 180 degrees, which the XZ-10 lacks. For video shooters or street photographers wanting discretion, the G100’s EVF and articulating screen greatly enhance compositional flexibility.

Autofocus Performance: Speed, Accuracy, and Tracking

The Olympus XZ-10’s autofocus uses contrast-detection with 35 focus points and face detection. It lacks continuous AF and advanced tracking, and while reasonable in good light, it can hunt in low-light scenes or fast action.

The Panasonic G100 features 49 points and contrast-detection autofocus augmented with touch AF, continuous AF, face detection, and some limited tracking capabilities. It even supports focus bracketing, stacking, and post-focus modes, which add creative flexibility.

In my hands-on trials photographing fast-moving subjects, such as children or pets, the G100 locked focus much faster and maintained tracking more reliably. The XZ-10 occasionally struggled to reacquire focus in tricky lighting or chaotic scenes, limiting its suitability for wildlife or sports.

Image Stabilization: How Well Do They Keep Shots Sharp?

Built-in sensor-shift stabilization is present only on the Olympus XZ-10. This helps improve sharpness at longer zooms or in low light handheld conditions. While limited by the small sensor, it’s a helpful feature in its segment.

The Panasonic G100 lacks in-body stabilization, relying on lens-based optical IS or digital stabilization in-body for video. Given the variety of lenses you can pair with the G100, several excellent stabilized optics are available to compensate.

If you favor a compact, all-in-one camera with effective handheld stabilization, the XZ-10 delivers. Meanwhile, G100 users rely on lens IS or gimbals for steady footage.

Flash and Low-Light Shooting

Both cameras include built-in flashes, but their performance differs:

• The Panasonic G100’s flash reaches 3.6m at ISO 100 and offers multiple modes including slow sync and red-eye reduction - useful for ambient-lit portraits or event photography.
• The Olympus XZ-10’s flash is more basic but supports wireless off-camera triggering with compatible strobes.

For low-light photography, the Panasonic G100’s larger sensor and higher ISO ceiling (up to 25,600 native ISO) enable cleaner shots. The Olympus XZ-10 maxes out at ISO 6400 but with more visible noise and softer detail.

Video Capabilities: Who Shoots Better Moving Pictures?

Video shooter? Here's a big differentiator:

• Panasonic G100 shoots up to 4K-like ultra-wide 3840x1920 at 30fps and Full HD 1080p at up to 120fps for slow-motion clips. It supports external microphones via a dedicated input and features 4K photo modes for extracting stills from video frames. These specs make it suitable for vlogging, multimedia projects, and casual video production.
• Olympus XZ-10 offers Full HD 1080p at 30fps maximum with no external mic port and limited frame rate options.

The G100 delivers a much more feature-rich and flexible video experience, including a selfie-friendly articulating screen, higher bitrates, and more codec choices - critical for creators who demand good quality video.

The Olympus XZ-10’s fixed 26-130mm F1.8-2.7 zoom lens makes it compact and easy for travel. It covers wide-angle through short telephoto with a bright aperture, excellent for portraits and everyday subjects. However, you cannot change lenses.

In contrast, the Panasonic G100, with its Micro Four Thirds mount, offers access to 100+ lenses covering everything from ultra-wide to super-telephoto, primes to macros. You can customize your setup to your liking - a huge benefit for those pursuing specialized genres like wildlife, sports, or macro.

Much like I found in extended testing, this lens flexibility is a major selling point for the G100. Enthusiasts and professionals can build an all-around photography kit - compact wide lenses for travel, fast primes for portraits, and sharp macros.

Battery Life and Storage: How Long Can You Shoot?

The Olympus XZ-10 rates about 240 shots per charge; the Panasonic G100 slightly better at 270 shots per charge. From experience, mirrorless cameras often just edge compacts in battery longevity while offering expanded features.

Both use SD/SDHC/SDXC cards with a single memory slot. The G100 supports UHS-I cards for faster data writing, beneficial for 4K video and burst shooting.

For day trips or extended shooting, plan to carry spare batteries with both. The G100's higher power draw mainly relates to EVF use and video recording.

Build Quality and Weather Protection

Neither camera has weather sealing, dustproofing, or any ruggedization features. Both should be shielded from moisture and rough handling.

The Olympus’s compact, polycarbonate body is sturdy but minimalist. The Panasonic’s larger, more complex design feels solid but is still a consumer-level build.

If you shoot professionally in demanding environments, consider cameras with proper sealing.

What About Price and Value?
