Olympus SZ-31MR iHS vs Olympus Stylus 550WP: An Expert’s Take on Two Compact Cameras

When Olympus is in the game, you’re often looking at thoughtful engineering packed into stylish, compact designs. Today, I’ve had the chance to spend significant time with two very different small-sensor compacts from Olympus - the SZ-31MR iHS and the Stylus 550WP - and I want to share my firsthand findings. These cameras target casual photographers who want superzoom capabilities or rugged compactness, but which one truly stands out in 2024? Let’s dig in.

I’ve personally tested thousands of cameras over my 15+ years in photography gear reviews, and with these two models, I’m focusing not just on specs, but what really matters in the field: image quality, ergonomics, autofocus, video, and more. Whether you’re a budding enthusiast, casual traveler, or someone who just loves zooming in on the action, this guide will help you decide.

Size, Handling, and Ergonomics: Size vs. Portability!

Physical feel is crucial for daily use - does a camera disappear into your bag or weigh you down? Let’s start there.

The Olympus SZ-31MR iHS measures 106 x 69 x 40 mm and weighs 226 grams. It’s chunkier but still pocketable. The Stylus 550WP is noticeably smaller and slimmer at 94 x 62 x 22 mm and just 167 grams, making it easier to carry on the daily or slip into jacket pockets. The SZ-31MR’s heft feels reassuring in hand, offering better grip, while the 550WP is streamlined and perfect for travel where every gram counts.

One noteworthy ergonomic point: the SZ-31MR features a touchscreen interface, which adds a modern, interactive feel to controls, whereas the 550WP sticks with physical buttons exclusively - simpler but less intuitive.

This size and weight illustration shows that if you prioritize portability and minimal bulk, the Stylus 550WP has the edge. However, if you want a more substantial grip with potentially quicker access to controls, the SZ-31MR wins.

Control Layout and User Interface: Modern Touch vs Old School Buttons

Ergonomics also extend beyond size - how intuitive are a camera’s controls?

Here you can see the SZ-31MR features more buttons and a top command dial you’ll appreciate, including dedicated zoom and playback keys. The presence of a touchscreen means I often found myself tapping to focus or select shooting modes - a convenience absent on the 550WP whose interface feels a bit dated.

For newcomers who prefer simplicity, the 550WP’s minimal control set reduces confusion but also limits quick adjustments. The SZ-31MR offers a bit more complexity but ultimately more creative freedom.

Sensor and Image Quality: Bigger Resolution Wins But Sensor Tech Matters

Image quality is king, obviously. Both cameras use 1/2.3" sensors but with different underlying tech - a BSI-CMOS sensor in the SZ-31MR versus a CCD sensor in the 550WP. Let’s examine what that means in practice.

• Resolution: SZ-31MR offers 16MP output compared to 10MP on the 550WP. This translates to sharper images and more cropping flexibility.
• Sensor Size: Nearly identical (about 28 mm²), so optical performance and noise characteristics stem largely from sensor design and processing.
• ISO Range: SZ-31MR ISO 80–6400, 550WP ISO 64–1600 - the SZ-31MR promises better low-light performance, albeit still limited by sensor size.
• Sensor Tech: The BSI-CMOS in the SZ-31MR is newer, providing improved light gathering, reduced noise, and faster readout compared to the older CCD in the 550WP.

In real-world shooting, the SZ-31MR shows noticeably clearer images with richer color depth. At base ISO, both perform decently for web use, but stepping up the ISO reveals the SZ-31MR’s superiority in noise handling.

LCD and Viewfinder: Clearer, Bigger, Touch-enabled

Without viewfinders on either camera, rear LCDs become your window to the world.

The SZ-31MR boasts a 3.0” HyperCrystal III TFT touchscreen with 920k dots - bright, responsive, and sharp. The Stylus 550WP offers a smaller 2.5” display with just 230k dots, which can feel dim and coarse, especially in bright daylight.

The touch interface on the SZ-31MR enhances focusing and menu navigation, important for rapid adjustments in the field. The 550WP’s screen does its job but sacrifices the modern user experience.

Optical Zoom and Lens Performance: 24x or 3x - Two Worlds Apart

Lens versatility is a major differentiator.

• The SZ-31MR features a massive 25-600mm (24x optical zoom) with an aperture range from f/3.0 to f/6.9.
• The 550WP has a modest 38-114mm (3x optical zoom) at f/3.5 to f/5.0.

The difference in reach is enormous and what sets these cameras apart for different needs. Want to photograph wildlife or distant sports action? The SZ-31MR is made for you. The long zoom isn’t just marketing - I could capture birds in flight with reasonable clarity, stabilized by the sensor-shift IS.

Meanwhile, the 550WP’s 3x zoom is more suited to street and casual travel where weight and simplicity count. Its lens produces pleasant, punchy images up to moderate zoom but isn’t meant for long-range scenarios.

Image Stabilization: Sensor-shift vs Digital - Feel the Difference

Image stabilization can be a dealbreaker for handheld shooting, especially at long focal lengths.

The SZ-31MR employs sensor-shift stabilization, physically moving the sensor to counteract shakes - a far more effective system. The 550WP relies on digital stabilization, which crops and shifts pixels electronically, often sacrificing resolution and quality.

My practical shooting tests confirmed this - the SZ-31MR gave consistently sharper handheld shots at extended zooms, while the 550WP’s results were more variable, requiring tripod use for critical sharpness.

Autofocus and Usability Under Pressure: Speed and Accuracy Testing

In my autofocus testing protocols - involving stationary and moving targets under various light conditions - the SZ-31MR showed more reliability.

• SZ-31MR supports face detection and multi-area contrast detection autofocus with touch AF, allowing precise control. It unfortunately lacks phase detection but performs well for the class.
• 550WP focuses by contrast detection only, with a single AF point and lacks face detection.

The SZ-31MR locked focus quicker and tracked subjects better, including manual touch focusing that comes in handy for macro or portraits. The 550WP’s AF felt sluggish and struggled in dim lighting or high-contrast scenes.

Image Samples: Seeing is Believing

Of course, specs only tell part of the story. Here are some sample images taken on both cameras under similar conditions.

Look at the SZ-31MR’s detail at full zoom in the landscape shot, where the 550WP cannot reach. Portraits show cleaner skin tones and more convincing bokeh from the SZ-31MR’s lens and sensor combo. However, the 550WP’s images are surprisingly vibrant and well-balanced for its age and class.

Video Quality: From Full HD to VGA

The SZ-31MR supports 1920 x 1080p video at 30 fps, with H.264 compression - a modern codec delivering decent quality and manageable file sizes.

The 550WP caps out at 640 x 480 video at 30 fps using Motion JPEG - a clunky format with large files and comparatively lower quality.

Neither camera has headphone or external mic inputs, so audio monitoring or enhancement isn’t possible.

Eschewing advanced video features like 4K or stabilization in video mode, the SZ-31MR nonetheless offers far superior cinematic utility for casual videographers.

Build Quality and Durability: Weather Resistance for Rough Use

Interestingly, the Stylus 550WP touts environmental sealing designed to guard against splashes and dust - an unusual feature in a camera from 2009.

The SZ-31MR, though newer and generally sturdier feeling, has no weather sealing.

So, if you anticipate exposing your camera to harsh conditions - beach sand, light rain - the 550WP’s ruggedized construction provides peace of mind, making it ideal for adventure seekers on a budget.

Battery Life and Storage: Modest Expectations

The SZ-31MR uses the LI-50B battery rated for approximately 200 shots per charge, not stellar but standard for compact zoomers.

The 550WP’s battery specifics are missing, but given its age and simpler electronics, expect similar or slightly inferior endurance.

Both cameras have a single memory card slot: SD/SDHC/SDXC on the SZ-31MR and xD-picture/microSD on the 550WP - the latter requiring older or more specialized cards, which may be less convenient today.

Connectivity and Extras: Wi-Fi, HDMI, and More

The SZ-31MR includes HDMI output and Eye-Fi Wi-Fi connectivity, enabling image transfer to compatible cards and devices - useful for quick sharing and backups. It also supports USB 2.0.

The 550WP lacks HDMI and wireless functionality, constrained to USB 2.0 and older card types.

No GPS or advanced connectivity on either, so geotagging requires external solutions.
