Olympus 550WP vs Panasonic Lumix G100: A Hands-On Comparison for Every Photographer’s Needs

When the hunt begins for the right camera, it’s easy to get overwhelmed by specs sheets and marketing jargon. As someone who’s tested thousands of cameras over the past 15 years, I know firsthand the value of cutting through the noise with practical, real-world insights. Today, I’m diving into a detailed comparison of two very different cameras: the ultra-compact Olympus Stylus 550WP (a budget-friendly rugged compact from 2009) and the more recent Panasonic Lumix DC-G100, an entry-level mirrorless boasting modern features designed with vloggers and enthusiasts in mind.

At first glance, they couldn’t be more different in design and purpose, yet each offers compelling benefits depending on your use case and budget. So, buckle up as we run through everything from sensor technology to autofocus, image quality, ergonomics, and their suitability across diverse photography styles. Whether you’re a travel junkie, a budding videographer, or a sports shooter looking for speed, this comparison will steer you right.

Size and Ergonomics: Pocketable vs. Club for Your Thumbs

Starting with form factor, these two are in different universes. The Olympus 550WP is a compact point-and-shoot weighing just 167g, with physical dimensions of 94 x 62 x 22 mm. It’s pocket-friendly, lightweight, and designed for casual shooting and easy carry - it fits comfortably in a coat pocket or small bag.

The Panasonic G100, meanwhile, is decidedly bulkier by compact-camera standards, weighing 352g with dimensions of 116 x 83 x 54 mm, sporting an SLR-style mirrorless body. This gives it more heft, grip, and a design intended for more serious handheld use with interchangeable lenses.

For photographers who appreciate minimalism and easy transport, the Olympus wins hands-down. But if you want physical dials and a camera that feels sturdy and snappy in hand during prolonged shoots, the Panasonic feels like a club for your thumbs in all the right ways.

The Olympus lacks any form of illuminated buttons or comprehensive manual controls, meaning you’re mostly shooting on auto or scene modes. Conversely, the Panasonic G100 is built with manual exposure control, shutter/aperture priority modes, and customizable buttons - essential features if you like having creative control at your fingertips.

Sensor and Image Quality: Small Sensor Compromises vs. Modern Micro Four Thirds Powerhouse

Here’s where the gulf widens. The Olympus 550WP uses a 1/2.3" CCD sensor, measuring 6.08 x 4.56 mm, yielding about 10 megapixels. It’s a sensor typical of compact cameras from that era - small, limited dynamic range, and prone to noise at anything beyond ISO 400. Its maximum native ISO tops at 1600 but expect image quality to degrade significantly before reaching that.

In contrast, the Panasonic G100 boasts a larger Four Thirds CMOS sensor, 17.3 x 13 mm, with 20 megapixels resolution. This sensor size approximately quadruples the surface area over the Olympus’s, enabling much better light-gathering ability, resulting in superior low-light performance, dynamic range, and color depth.

From practical testing, the G100 produces punchier, cleaner images up to ISO 3200 with usable noise levels, whereas the 550WP’s images get muddy and desaturated by ISO 800 at the latest. Resolution also counts here; the Panasonic’s 20MP file allows larger prints and more cropping flexibility, while the Olympus caps at 10MP - fine for small prints or online sharing but limiting for heavy editing.

Design and Controls: Analog Feel with the Olympus vs. Versatile Touchscreen Interface on Panasonic

The Olympus 550WP has a neat, simple control scheme: a fixed 2.5-inch LCD with modest 230k-dot resolution, no touchscreen, no live exposure preview except in live view, and no electronic viewfinder (EVF). It’s all very basic - think “point and shoot and hope for the best.” There’s no eye-level finder for precise framing in bright sunlight, and shooting menus can be slow.

The Panasonic G100 ups the ante with a fully articulating 3-inch touchscreen LCD at 1,840k dots that supports touch AF, menu navigation, and self-recording for vloggers. The electronic viewfinder is sharp at 3,680 dots with 100% coverage and 0.73x magnification, making it easy to compose in any lighting.

Both have built-in flashes, but Panasonic’s external flash compatibility adds flexibility missing on the Olympus.

Olympus fans get rugged, simplistic controls, but Panasonic users enjoy modern UI conveniences and expanded manual tweaking.

Autofocus and Burst Shooting: Slow and Steady vs. Fast and Flexible

If you’re shooting wildlife, sports, or any action-packed scenes, autofocus and burst rate matter most. Unfortunately, the Olympus 550WP can only manage single autofocus with contrast detection, no continuous AF or tracking - meaning it hunts in low light or with moving subjects.

The Panasonic G100, while lacking phase detection autofocus (which some higher-end mirrorless cameras have), offers contrast detect autofocus with 49 focus points, face detection, continuous AF, tracking, and selective AF modes. It also supports focus bracketing, stacking, and post-focus features, which are game changers for macro and creative shooting.

Burst shooting is similarly divergent. The Olympus doesn’t advertise continuous shooting, certainly not at speed. The Panasonic hits a solid 10 fps, which is respectable for entry-level mirrorless and perfectly capable for casual sports and wildlife shooting.

Real-World Photography Use Cases

Let’s break down how these two cameras serve across popular photography disciplines:

Portrait Photography

• Olympus 550WP: Limited manual control and fixed lens zoom (38-114mm equivalent, f/3.5-5.0) means limited bokeh and subject isolation. No eye-detection AF means focus is manual or center-weighted only. Skin tones are acceptable in bright light but can lack nuance due to small sensor and JPEG processing.

• Panasonic G100: With interchangeable lenses and face/eye AF, the G100 excels in portraits. The larger sensor allows better background separation and attractive bokeh when paired with a fast prime. Custom white balance and raw shooting provide nuanced color rendering.

Landscape Photography

• Olympus’s modest dynamic range and small sensor limit shadow and highlight detail. The fixed lens’s 38mm wide angle is acceptable but not expansive.

• Panasonic’s 20MP sensor delivers superior detail and dynamic range for landscapes, and weather sealing might be missing, but lens choices cover everything from ultra-wide to super-telephoto.

Wildlife and Sports Photography

• Olympus’s slow contrast detect AF and no burst make it ill-suited for these genres.

• Panasonic’s 10 fps burst and continuous AF make it far better for tracking moving subjects, though its autofocus might struggle in very low light compared to phase detection systems.

Street Photography

• Olympus’s compact size and discreet profile make it a winner in street shooting, coupled with decent image quality for casual shots.

• Panasonic is bulkier but still relatively portable. Its articulating screen and EVF help capture candid moments without drawing too much attention.

Macro Photography

• Olympus allows macro focusing down to 7 cm but limited lens control and digital image stabilization limit quality.

• Panasonic supports focus stacking and bracketing with compatible lenses, enabling much sharper and creative macro work.

Night and Astrophotography

• Olympus’s ISO limit and sensor noise don’t lend well to night shooting.

• Panasonic’s higher ISO capabilities and manual controls allow more long-exposure flexibility.

Video Capabilities

• Olympus offers basic 640x480 VGA video at 30 fps, insufficient by today’s standards.

• Panasonic G100 is a strong video contender: 4K video up to 30p, Full HD at up to 120p for slow motion, built-in mic input, and a fully articulated screen make it ideal for vloggers and casual filmmakers.

Travel Photography

• Olympus’s small size and weather resistance make it perfect for hiking and travel in rough conditions, but the image quality and controls are basic.

• Panasonic’s versatility and interchangeable lenses cater to those who want quality in varied situations but at a cost of size and weight.

Professional Work

• Olympus 550WP lacks raw format, manual control, and professional features needed for critical work.

• Panasonic supports raw, offers flexible exposure modes, and fits into a professional workflow far better.

Build Quality and Weather Resistance

While the Olympus 550WP boasts environmental sealing, it does not claim waterproof, dustproof, shockproof, or freeze-proof certifications. That said, its compact rugged build is surprisingly resilient for a point and shoot.

The Panasonic G100 lacks weather sealing or rugged protection, so caution is needed in harsh environments, but the metal-and-plastic build is solid for regular use.

Battery Life and Storage

• Olympus uses proprietary battery models (details scarce) with modest battery life, but saving grace is its small sensor and low-res screen, which are less power-hungry.

• Panasonic offers approximately 270 shots per charge, fairly average for mirrorless cameras, with SD/SDHC/SDXC card support (UHS-I).

Both have a single card slot setup; Panasonic supports more modern and reliable SD cards, contrary to Olympus's older xD-Picture and microSD formats.

Connectivity and Wireless Features

The Olympus provides no wireless connectivity - no WiFi, Bluetooth, or GPS.

The Panasonic G100 brings built-in WiFi and Bluetooth (great for instant sharing and remote control), HDMI out, and a mic port, underscoring its video and social media-friendly design.

Price-To-Performance: Budget Basics vs. Modern Versatility

Currently priced around $399 for the Olympus 550WP (though this is a legacy camera, so availability is limited) versus around $698 for the Panasonic G100, the two sit at very different value levels.

For cheapskates or casual shooters wanting something small and rugged for snapshots, the Olympus still holds charm. But for anyone seeking more control, better image quality, and video - especially vloggers and enthusiasts - the Panasonic G100 delivers a clear step up.
