Olympus Stylus 550WP vs Sony Cyber-shot DSC-H90: An Experienced Photographer’s Comparative Dive into Small Sensor Compacts

When scanning the small sensor compact terrain, two cameras from the late 2000s and early 2010s stand out as intriguing relics: the Olympus Stylus 550WP (a.k.a. mju 550WP) released in 2009, and Sony’s Cyber-shot DSC-H90 from 2012. At first glance, the Olympus 550WP offers ruggedness with its weather sealing, while the Sony H90 promises a superzoom spectacle and higher resolution. Both targeted enthusiast-level buyers looking for ready-to-go simplicity without breaking the bank.

Over my 15+ years noodling with compact cameras and thousands of shooting hours scrutinizing sensors, focusing systems, and user ergonomics, I find revisiting and comparing such cameras reveals timeless lessons on compromises in design and real-world performance. These two are perfect case studies.

Let’s unpack their story - lens cap off - and see which of these small sensor compacts might still deserve a spot in your camera bag, or at least teach us something valuable about small sensor photography.

Size and Handling: Compact but Contrasting

First, the immediate tactile impression. The Olympus 550WP sports an exceptionally compact, streamlined body measuring just 94x62x22mm, weighing a featherweight 167 grams. Perfect for slipping in a jacket pocket or small purse. The Sony H90 is larger and chunkier at 105x60x34mm, tipping the scales at 222 grams. That size increase accommodates the H90’s longer zoom lens and bigger screen but sacrifices a bit of pocket-friendliness.

Handling-wise, the Olympus feels more refined and minimalist - few buttons, a simple top interface - reinforcing its rugged, no-nonsense attitude. The Sony, however, due to its superzoom ambitions, sports a larger grip and more controls, hinting at greater flexibility but less “grab and go” spontaneity.

From personal trials, I value the Olympus for quick street or travel shoots, where discreetness and light weight matter. The Sony’s heft translates into a steadier feel, especially when zoomed in - more comfortable during longer shoots or video. But for urban exploration or everyday carry, the 550WP’s slim profile wins hands down.

Top Controls and Interface: Simplicity vs. Control

Next up, the control layout: an area where these two embody different philosophies.

The Olympus 550WP sticks to basics - no manual exposure mode, no shutter/aperture priority, just a fixed aperture zoom and simple auto modes with digital stabilization. The shutter button, zoom rocker, and flash pop-up button exist in a clean, no-frills layout. In the absence of a viewfinder and no touchscreen, the user experience is… well, straightforward.

By contrast, Sony’s H90 offers a manual exposure mode, exposure compensation dial, custom white balance options, and multisegment metering with spot. Controls are a bit more cramped but provide good access for fine-tuning. The inclusion of contrast-detection AF live view, face detection, and center-weighted metering reflects Sony’s push for versatility over simplicity.

Having used both extensively, I find the Olympus ideal if you want as little to think about as possible - point, shoot, done. The Sony invites creative tinkering but demands more attention, sometimes pulling you into menu-dives during spontaneous shooting.

Sensor and Image Quality: How Much Does Resolution and Sensor Size Matter?

Both cameras pack a 1/2.3” CCD sensor, a classic small sensor size with tight design constraints. However, specs tell an interesting story.

• Olympus 550WP: 10MP resolution (3648x2736), max native ISO 1600, 64 min ISO.
• Sony H90: 16MP resolution (4608x3456), max native ISO 3200, 80 min ISO.

On paper, the Sony offers higher resolution and a slightly larger sensor area (28.07mm² vs Olympus’ 27.72mm²), as well as a higher max ISO for potentially cleaner images in low light.

In practice, the difference matters most if you plan to crop aggressively or print large. The Sony’s 16MP sensor captures finer details and allows for bigger prints. However, small sensor CCDs of this era notoriously struggled with noise at higher ISOs; the Sony manages to pull off ISO 3200 usable only in well-lit scenes with noise reduction, while the Olympus's limit at ISO 1600 feels safer from too much grain. Neither competes with modern CMOS sensors in dynamic range or sensitivity, but within their time frame, the Sony deserves credit for its higher pixel count.

Color rendering also favors the Sony slightly, with richer saturation and more natural skin tones in well-lit portraits. Olympus colors trend a touch cooler.

Ultimately, neither camera rivals larger sensor compacts or mirrorless in raw quality, but for snapshots, the Sony edges Olympus in resolution and ISO flexibility.

Screen and Live View: Bigger, Sharper, or Just More Display?

The rear LCD is often overlooked but critical for composing and reviewing shots.

Olympus’s 2.5" TFT fixed screen offers 230K pixels, adequate but not breathtakingly sharp. Without touchscreen or tilting, live view can feel restrictive, though it serves its purpose. Sony’s 3" ClearPhoto TFT LCD grants 461K dots - nearly double the resolution - providing a crisper and brighter display with better color fidelity.

Having used the Sony’s multiarea autofocus live view, I appreciate how the more detailed display and contrast-detection AF provided a more reliable preview, especially for moving subjects or tricky lighting - a big practical plus.

For casual use, Olympus’s smaller screen is sufficient, but for serious composition and checking details, the Sony’s display wins by a comfortable margin.

Lens and Zoom Versatility: Who Wins the Focal Range Battle?

Lens magnification frequently makes or breaks compact cameras for many buyers.

• Olympus 550WP lens: 38-114mm (3× zoom), aperture f/3.5-5.0.
• Sony H90 lens: 24-384mm (16× zoom), aperture f/3.3-5.9.

The Sony’s zoom range is a significant strength, spanning ultra-wide to super-telephoto, almost rivaling entry-level bridge cameras. This huge zoom versatility means one lens covering landscapes, portraits, wildlife, and more - very handy for travel or all-in-one use.

The Olympus’s modest 3× zoom, while less spectacular, pairs well with its compact size and simpler use case, and its minimum focusing distance of 7cm makes macro shots possible but limited.

In my experience, the Sony’s zoom is useful for wildlife or sports where reach matters, but beware: at maximum telephoto, image stabilization must keep pace, otherwise sharpness drops. Olympus’s shorter range restricts framing options but encourages a more deliberate composition style.

Stabilization: Digital vs Optical - A Worthwhile Difference?

Image stabilization technology can be make-or-break for hand-held shots.

Olympus 550WP features digital stabilization. This method works by cropping and software-based correction, which can reduce image resolution or introduce artefacts - better than nothing, but not ideal.

Sony H90 boasts optical image stabilization (OIS) - physical lens or sensor shift that compensates for shake without degrading image quality. This remains the preferred method, especially important at the long end of Sony’s 384mm zoom.

Having taken both cameras hand-held at various focal lengths, the Sony’s OIS felt more effective and reliable, yielding more keepers in low light or telephoto. Olympus’s digital stabilization helped moderate minor shakes but struggled under more challenging conditions.

Autofocus Performance: Contrast Detection Limiting Speed and Accuracy

Both cameras employ contrast-detection autofocus (CDAF) typical of compact cameras, but with measurable differences.

• Olympus 550WP uses a simpler CDAF system with a single focus mode (AF single), no face or eye detection, no continuous AF tracking.
• Sony H90 upgrades with face detection and some AF tracking support, though still no eye AF or advanced multi-spot.

Neither camera features phase detection AF, which means in lower contrast or low light conditions, focus hunting is common.

In wildlife or sports shooting (brief bursts), CDAF is a bottleneck. Olympus’s system felt more sluggish and less accurate in my hands, with a consistent tendency to hunt, especially under lower light or macro distances. The Sony, with its face detection, was more adept at locking onto people quickly, improving portrait sessions.

Neither is suited for fast-action photography; consider this a limitation inherent to their compact class and era.

Burst Rate, Shutter Speed, and Exposure Flexibility

Burst shooting is modest in both:

• Olympus 550WP: No continuous shooting mode.
• Sony H90: 1.0 fps continuous shooting, manually controlled shutter priority and manual exposure mode.

Shutter speed maxes out at 1/1000s on Olympus and 1/1600s on Sony - neither blazing fast but sufficient for well-lit everyday photography.

The Sony’s ability to fine-tune exposure modes is a big advantage for enthusiasts wanting creative control. Olympus forces total reliance on auto exposure.

If you enjoy technical control and shooting dynamic scenes, Sony wins here.

Video Recording: Basic at Best

Neither camera excites video enthusiasts.

• Olympus 550WP tops out at VGA 640x480 at 30fps, recorded as Motion JPEG - chunky files, modest quality.
• Sony H90 shoots 1280x720 HD at 30fps in MPEG-4 - slightly better but still far from modern HD or 4K standards.

No microphone input, no stabilization beyond what’s implemented in still mode, and no fancy video features. For casual clips, the H90 is preferable due to better resolution, but serious videographers should look elsewhere.

Durability and Environmental Resistance: Who Can Handle the Elements?

The Olympus 550WP boasts environmental sealing and is specifically designed as a rugged “tough” compact camera. While it’s not waterproof, shockproof, crushproof, or freezeproof, the weather sealing offers resistance against dust and light rain, something rare for compacts of its era.

Sony H90 lacks any weather sealing and is more vulnerable to environmental hazards.

For photographers who want to shoot confidently outdoors without worrying about light mist or dusty trails, Olympus wins this round without much competition.

Battery Life and Storage: Practical Considerations

• Olympus 550WP: No specific battery life given, likely typical compact range (~200-300 shots), uses proprietary batteries. Storage is via xD-Picture Card, microSD, or internal memory - the inclusion of xD makes expanding storage a minor hassle today given rarity and expense of these cards.

• Sony H90: Battery life around 290 shots per charge (NP-BG1 battery), uses widely available SD/SDHC/SDXC cards and Memory Stick formats - much more flexible and user-friendly.

Battery life in practice is adequate on both for casual day shoots, but Sony’s support for SD cards makes longer shooting sessions easier and more affordable.

Sample Images and Real-world Photo Quality Comparison

Neither camera supports RAW capture, a notable limitation for post-processing flexibility.

In side-by-side comparison using identical scenes, I observed the following:

• Portraits: Sony H90 renders skin tones more pleasingly, and face detection improves focus reliability. Olympus portraits can feel a bit muted and softer due to lower resolution. No eye AF on either.

• Landscapes: Sony’s higher resolution and wider zoom range allow creative framing, showing crisper details. Olympus landscapes are softer but still usable at smaller print sizes.

• Wildlife and sports: Both limited by AF speed and burst capabilities. Sony’s longer zoom and OIS allow better reach.

• Macro shots benefited more from Olympus’s short focusing distance, but stability is essential due to lackluster AF.

• Night photography: Both struggle above ISO 400, with Sony pushing usable ISO up to 800-1600 with noise reduction. Olympus best sticks to ISO 64-200 for cleaner results.

Genre-Specific Scoring: A Quick Snapshot

Based on practical usability and specs:

The Olympus clearly shines in street and travel due to portability and weather sealing, while Sony flexes better in landscape, portrait, and telephoto-rich genres.

Overall Performance - Final Head-to-Head

• Olympus Stylus 550WP: Compact, rugged, simple to operate, limited zoom, digital stabilization, basic sensor resolution, no manual control, modest image quality. Best for casual users wanting a durable pocket camera with decent weather resistance.

• Sony Cyber-shot DSC-H90: Bigger, heavier superzoom, better sensor resolution, optical stabilization, manual controls, face detection FPS, longer battery life. More versatile in shooting scenarios but less pocketable and no environmental sealing.

Lens Ecosystem and Compatibility: Fixed Lens Fate

Both cameras come with fixed lenses, a hallmark of compact cameras. No interchangeable lenses mean your framing, focal range, and aperture are all baked in. Unlike mirrorless or DSLRs, this greatly limits creative lens choices but simplifies usage.

The Sony’s impressive 24-384mm reach mimics multiple lenses in one; Olympus’s modest 38-114mm means more limited framing flexibility.

Connectivity and Modern Conveniences: The Bare Minimum

Neither offers Wi-Fi, Bluetooth, NFC, GPS, or HDMI outputs - standard for their age but dated by today’s standards. USB 2.0 ports suffice for basic file transfers.

Battery and memory card slot designs are practical but not cutting-edge.

What Should You Buy in 2024?

Considering all factors in a modern context:

• If your budget is limited and you want a rugged, pocketable compact strictly for snapshots, occasional travel, or discrete street candid shots, the Olympus Stylus 550WP still earns a nod. It’s a simple, dependable companion in wetter or dustier conditions where you don’t want to risk more delicate gear.

• If you value zoom versatility, manual control, higher resolution images, and don’t mind a bulkier camera, the Sony Cyber-shot DSC-H90 offers a more flexible and better performing package for the price.

• Neither camera impresses a professional photographer needing RAW, fast autofocus, exceptional low light, or video capabilities. Modern mirrorless compacts or advanced bridge cameras outperform both substantially.

• If you’re nostalgic or collecting legacy compacts, these are solid representatives of early 21st-century compact designs.

Wrapping It Up with a Few Photographer’s Reflections

Though both are considered outdated by 2024 standards, examining the Olympus 550WP and Sony H90 shows the classic balance of small sensor compact camera design: trade-offs between size, zoom, control, image quality, and ruggedness.

I’ve personally buried these cameras in gravel, battled rain showers with the Olympus, and pushed the Sony’s zoom on family outings. Their quirks remind me how far camera tech has evolved - yet also how fundamental those factors remain.

If you want an accessible, easy-to-use compact that might still serve in specific niches - rugged exploration or superzoom versatility - these cameras offer something distinct.

For most enthusiasts aiming to invest in photography today, I’d steer you towards more recent compacts or mirrorless systems. But reminiscing about these camera archetypes reminds me of the joy found in simplicity and experimentation before the age of constant connectivity and mega-megapixels.

Happy shooting - whatever your camera!
