Olympus 550WP vs Olympus TG-4: A Hands-On Deep Dive from an Experienced Camera Tester

Choosing a camera in the compact rugged category can feel like comparing apples to oranges – sometimes even within the same brand. As someone who's handled a mountain of gear over 15+ years, I’m here to unravel the real practical differences between two Olympus compact models separated by six years: the 2009 Olympus Stylus 550WP (hereafter "550WP") and the 2015 Olympus Tough TG-4 ("TG-4"). Both compact, both rugged-ish, both carrying Olympus’ heritage, but targeted at very different photographers.

In this piece, I’ll walk you through every aspect that matters - from sensor tech and shooting experience to real-world use cases like travel, underwater adventure, and macro photography. I’ll aim to answer: Which one is worth your hard-earned cash? And for whom? Let’s not junk this with specs alone; instead, I’ll share hands-on experience, testing insights, and practical verdicts.

Breaking Down First Impressions and Ergonomics

Before you even power these cameras on, how they feel in your hands and what physical features they offer can shape your shooting mood and usability dramatically.

The Olympus 550WP is a slim, pocketable compact with body dimensions of 94x62x22mm and weighing only 167g. Its design screams “casual shooter,” a simple rectangular block with minimal controls and no viewfinder - relying solely on a fixed 2.5-inch screen with low resolution (230k dots). There’s no touchscreen, no articulated screen, and frankly not much in the way of physical controls - just a cluster of dinky buttons without illumination. It manages to have environmental sealing but crucially it’s not truly waterproof, shockproof, or freezeproof.

Contrast that trim figure to the TG-4, a chunkier beast at 112x66x31mm and 247g, clearly built like a rugged wrist-anchored tank. Olympus really set out to make this camera a tough companion: waterproof to 15m, shockproof from 2.1m, freezeproof to -10°C, dustproof, and crushproof. Plus, it’s got a beefier, larger 3-inch 460k dot LCD - still fixed, but easier on the eyeballs and usability in bright daylight.

Controls on the TG-4 are leagues ahead: dedicated dials, well-placed buttons for exposure compensation, ISO, mode, and a quick access menu. The TG-4 sports Olympus' typical “clubs for thumbs” grip – sturdy and secure even with gloves. No viewfinder here either, but with true weather sealing and grip, it’s ready for rough adventure.

If you’re a prepper for rough outdoor use or rugged travel, the TG-4’s build and ergonomics make it a no-brainer. But if pocketability and simplicity rule your day, the slimmer 550WP is easier to pocket, just remember it’s less ready for abuse.

Sensor, Image Quality, and Processing: The Heart of the Matter

Both cameras employ a 1/2.3” sensor size, but that is where similarity ends. The 550WP leverages an older 10-megapixel CCD sensor - a technology that was common around 2009 but has since been mostly replaced by CMOS in compact cameras due to better speed, low-light performance, and flexibility.

The TG-4 shoots with a 16-megapixel backside illuminated CMOS sensor (BSI-CMOS), a significant upgrade in terms of dynamic range, noise control, and resolution. Both have an anti-aliasing filter, but the TG-4’s sensor has slightly larger physical dimensions (6.17x4.55mm vs 6.08x4.56mm), offering a modestly larger sensor area (28.07mm² vs 27.72mm²).

From my lab tests and field experience:

• Dynamic range and Color Depth: TG-4 outperforms by offering more latitude in shadows and highlights, rendering better skin tones and richer colors - crucial for portrait and landscape enthusiasts. The 550WP’s CCD sensor produces slightly flatter files, with less room for recovery in post.

• ISO Performance: The TG-4 extends native ISO up to 6400 with useable results up to 1600-3200, whereas the 550WP tops out at ISO 1600 but with significant noise creeping in as soon as you nudge past ISO 400. Low-light shooting or night photography severely favors the TG-4.

• Resolution and Sharpness: TG-4’s higher megapixel count and better processing pipeline yield sharper files with richer detail. Both cameras apply anti-aliasing filters, so fine detail resolution is naturally tempered to avoid moiré, but TG-4 still nails finer detail for landscapes and wildlife alike.

In short, if image quality and flexible shooting are priorities, the TG-4’s sensor and processor combo give it a substantive edge - even when viewing larger prints or cropping in tight.

Lens and Shooting Range: Flexibility across Focal Lengths and Aperture

The fixed zoom lens on a compact camera is mission-critical, especially when you can’t swap glass. Let’s compare:

• Olympus 550WP: 38-114mm equivalent (3x zoom), maximum aperture f/3.5-5.0
• Olympus TG-4: 25-100mm equivalent (4x zoom), maximum aperture f/2.0-4.9

What this means in practice is that TG-4 starts wider (25mm vs 38mm), great for landscapes and street scenes, where you want more context or a wider field of view. The 4x zoom offers slightly less reach at the telephoto end (100mm vs 114mm), but honestly, the 14mm difference is unlikely to sway most shooters.

The much faster aperture at the wide end (f/2.0 on TG-4) is a boon for low-light and shallow depth of field (DOF) shots, something the 550WP struggles with at f/3.5, especially indoors or dusk. The TG-4 shines for macro as well, with a minimum macro focus distance of 1 cm compared to the 7 cm on the 550WP, allowing you to get exquisitely close and capture fine details with lovely natural bokeh.

This, combined with the TG-4’s focus bracketing and stacking capabilities (non-existent in the 550WP), makes it a strong contender for macro shooters and nature photographers.

Autofocus and Shooting Speed: Timing is Everything

Here’s where technology leaps show significant impact. The 550WP’s autofocus is contrast-based, single point only, without continuous or tracking modes. That’s fine for static subjects, but frustrating if your scene involves movement or unpredictable subjects - the 550WP will often hunt or miss focus altogether.

By 2015, the TG-4 boasted 25 autofocus points (including center-weighted and multiarea), continuous autofocus, face detection, and even autofocus tracking. This means that for sports, wildlife, or kids running around, the TG-4 is far more reliable in locking focus swiftly. It can shoot at 5 frames per second burst, which the 550WP lacks entirely (no continuous shooting mode at all).

If you plan to shoot moving subjects or want a relaxed shutter lag, the TG-4 leaves the 550WP in the dust. I tested both on a flock of pigeons in flight and the TG-4’s tracking kept up, while the 550WP missed most shots or focused on the background.

Weather Sealing and Durability: Ruggedness Tested in Real Life

If you’re an adventurous photographer, your kit must survive more than just friendly environments.

The 550WP is environmentally sealed but not waterproof or shockproof. This limits its use in wet conditions or dusty environments. Personally, I’m wary of taking it underwater or into harsh settings despite manufacturer claims for basic weather sealing.

The TG-4, by contrast, is an all-out rugged camera. Waterproof to 15 meters, shockproof against drops up to 2.1 meters, freezeproof to -10°C, dustproof, and crushproof - it is purpose-built for harsh environments and adventure photography. Whether shooting in rain, snow, under water, or in dusty deserts, I trust the TG-4 to soldier on where the 550WP would shy away.

From day hikes with mud, ocean dips, to macro sessions on frosty mornings, the TG-4 has proven tough and durable, better suited for hands-on explorers and outdoor shooters.

Screen and Interface: What You See Is What You Get

The TG-4 sports a brighter, larger 3-inch 460k dot LCD, improving framing accuracy and playback visibility, particularly in bright conditions. The 550WP’s 2.5-inch 230k LCD is smaller and dimmer, which strains the eyes when shooting in sunlight or trying to confirm focus.

Neither camera has a viewfinder (optical or electronic), so you rely fully on the rear screen. The 550WP’s lack of touchscreen or even illuminated buttons means fumbling in low-light shooting. The TG-4 offers better button placement, easier access to menus, and is generally easier to operate quickly.

Video Capabilities: Basic to Functional

While these cameras are primarily photographic tools, video is often an afterthought in compacts.

The 550WP only manages VGA (640x480) at 30fps in Motion JPEG - essentially legacy standard, low-detail, and clunky file sizes. No HD video, no mic ports, and no modern codecs.

The TG-4, while no 4K superstar, shoots Full HD 1080p at 30fps with H.264 compression, offering decent quality video for casual clips. No microphone input or headphone jack limits audio customization, but in-camera stabilization helps during handheld recording.

For vloggers or video-centric content creators, neither is ideal, but TG-4’s video is far more serviceable and modern.

Battery Life and Storage

If you hate swapping batteries mid-shoot, the TG-4’s 380-shot battery life (using the LI-92B pack) is respectable for a compact of this type. The 550WP’s battery life specs are unavailable but generally shorter, reflecting older battery tech and less efficient components.

Both cameras use single memory card slots with differing card types: the 550WP accepts xD-Picture Cards or microSD cards - a now-defunct standard that makes sourcing cards tricky. The TG-4 uses SD/SDHC/SDXC cards - all still widely available today. The TG-4 also includes some internal memory for emergencies.

Connectivity and Extras

Neither camera offers Bluetooth or NFC, but the TG-4 includes built-in GPS for geotagging your adventures - a notable advantage if you want to track your shooting locations and organize trips by place.

The TG-4 supports HDMI output for viewing images and video on larger screens, while the 550WP does not.

Real-World Sample Photos: Who Shines Where?

Having shot side-by-side in nature, indoor portraits, macro, and street scenarios, the TG-4 consistently delivers cleaner images with better detail and color fidelity. Skin tones are more natural, dynamic range wider, and images crisper thanks to the higher resolution sensor.

The 550WP photos tend to lack vibrancy and sharpness, with slower focusing that leads to missed moments outdoors. Under macro conditions, 550WP struggles to focus closer than 7cm, losing bokeh artistry and tiny details the TG-4 captures effortlessly.

For casual snapshots or budget buyers, the 550WP can suffice, but professionals or enthusiasts will quickly find the TG-4’s output better fit for portfolio or serious work.

• • based on current street prices and features for photography enthusiasts

Which Camera Fits Your Photography Style?

• Portraits: TG-4 wins hands-down with richer skin tones, faster AF face detection, and wider aperture. 550WP’s lack of manual control and slower AF is a turnoff.
• Landscape: TG-4 has better dynamic range, wider angle lens, and weather sealing for the outdoors - ideal for serious landscape shooters.
• Wildlife: TG-4’s continuous AF and burst mode help here, plus better focal length range; 550WP isn’t suited for action or fast subjects.
• Sports: Shooting fast-moving subjects favors TG-4’s autofocus and burst capabilities. 550WP offers no continuous shooting, so skip it.
• Street: 550WP is smaller and more pocketable, better for stealth street shooting, but image quality compromises may hurt. TG-4 is bulkier but better in low light.
• Macro: TG-4’s 1cm macro focus, focus bracketing, and stacking give it the crown. The 550WP can’t compete at that level.
• Night and Astro: Neither camera excels, but TG-4’s higher ISO range and stabilization fare better in lower light.
• Video: TG-4 clearly better with HD recording and stabilization, though neither is great for serious videography.
• Travel: TG-4’s ruggedness and versatility trump 550WP’s compactness unless extreme portability is top priority.
• Professional Use: 550WP lacks manual controls and RAW, making TG-4 better suited for serious workflows, albeit still a compact enthusiast camera rather than pro-level gear.
