Olympus TG-630 iHS vs. Sony Cyber-shot DSC-W550: A Practical, In-Depth Comparison

Choosing your next compact camera often feels like deciphering hieroglyphs - so many specs, so many promise-filled buzzwords, and a decent dose of hopeful marketing bravado. Today, we’ll demystify two intriguing entries from the early 2010s compact camera wars: Olympus’s rugged TG-630 iHS and Sony’s sleek Cyber-shot DSC-W550. While their specs reflect the era’s state-of-the-art for point-and-shoot models, each carved out its niche. Having spent days shooting in varied conditions, testing controls, and comparing results pixel by pixel, I’m here to guide you through which might suit your needs, preferences, and shooting style.

First Impressions: Size, Build, and Ergonomics

Before plunging into megapixel wars or autofocus wizardry, it’s crucial to touch and hold these cameras - as I always insist. The Olympus TG-630 is bravely hefty for a compact at 167g, measuring 98x66x22mm. It’s not just weight; it screams confidence with physical weather sealing - waterproof, dustproof, shockproof, crushproof, and freezeproof. Ideal if you’re as clumsy as I am or if your adventures frequently stray from cozy studios.

The Sony Cyber-shot W550 is far more demure and feather-light at 110g, slipping easily into pockets at 94x56x19mm. The W550’s no rugged warrior; it’s a straightforward ultracompact built for casual shooters prioritizing portability over abuse-resistance.

Ergonomically, Olympus’s slightly larger footprint allows firmer hand grip and bigger buttons, which I appreciated during active shooting or when wearing gloves on chilly hikes. Sony’s W550 favors sleekness at some expense to precise handling, feeling a little fiddly for anyone with bigger hands or who craves tactile feedback.

Control layout also supports these differing philosophies. Olympus favors dedicated buttons for flash, macro, and drive modes, streamlining quick access. The Sony keeps it minimalist - menus hide many settings, a choice that casual users may prefer but pros might find slow and frustrating.

Sensor Size and Image Quality: The Heart of the Matter

At the sensor level, both cameras share a similar 1/2.3” footprint (about 6.17x4.55mm), a common size for compact cameras of their generation. Sensor size tells part of the story: it affects noise handling, dynamic range, and depth of field control. Smaller sensors like these limit low-light performance compared to larger APS-C or full-frame sensors but keep lenses and overall costs down.

Olympus opts for a 12-megapixel CMOS sensor, whereas Sony's 14-megapixel CCD is slightly higher resolution but different technology. CMOS sensors, like that in the TG-630, generally excel at faster readout, better high ISO noise control, and lower power consumption, whereas CCD sensors, like in the W550, often deliver pleasing color rendition but lag behind in speed and noise management.

In real-world shooting, Olympus’s CMOS sensor showed moderately better performance in low light at ISO 400 and above - noise becomes more apparent faster in Sony’s W550 images. Plus, Olympus’s sensor supports notable backside illumination technology (typical of later CMOS variants), aiding light gathering efficiency. The resolution difference is close enough that image sharpness depends more on lens quality and processing.

Don’t expect either to challenge DSLR or mirrorless cameras in dynamic range or detail retention under tough lighting scenarios. But within their class, Olympus slightly edges out Sony’s sensor performance - especially when pushing exposure latitude in shadows.

The Screen Experience: Seeing Your Shot Clearly

Both cameras feature a fixed 3-inch LCD screen. However, resolution and display tech vary. Olympus TG-630's screen is a crisp 460k dots, making menus and image playback vivid and easier to judge focus and exposure outdoors.

Sony’s W550 has a noticeably lower resolution Clear Photo LCD screen at 230k dots - adequate indoors but struggles under bright sunshine, making framing or checking detailed focus a guessing game.

Neither has a viewfinder or touchscreen, a typical limitation on compacts of this vintage - and somewhat expected. My experience with Olympus's brighter screen facilitated better manual tweaks and confident composition, especially in tricky light.

Autofocus & Shooting Speed: Focus Precision Under Fire

Autofocus (AF) performance - particularly speed and accuracy - is a decisive factor for many. Olympus’s TG-630 uses contrast-detection with face detection and even rudimentary tracking. Sony’s W550 also relies on contrast detection but lacks face detect autofocus.

In quiet daylight, both cameras focus fairly quickly on their limited focus points, but Olympus pulls ahead with better accuracy and the ability to track faces, reducing missed focus on moving subjects in portraits or casual street shots.

Burst shooting matters if you’re sports or wildlife inclined. Olympus delivers a somewhat nimble 5 fps continuous rate, a much appreciated surprise given its class and sensor type. Sony’s paltry 1 fps continuous shooting limits utility beyond sporadic snapping.

Lens and Zoom: Macro, Telephoto, and Versatility

Both cameras employ fixed zoom lenses with slightly different focal ranges and maximum apertures:

• Olympus TG-630: 28-140mm equivalent, f/3.9-5.9
• Sony W550: 26-104mm equivalent, f/2.7-5.7

Sony's wider starting aperture (f/2.7) at wide-angle helps in lower light and offers better background separation. Its shorter telephoto reach means less flexibility for distant subjects. Olympus’s 5x zoom extends to 140mm, adding reach beneficial for moderate telephoto use - think portraits, street candids, or travel.

For macro, Olympus’s ability to focus as close as 1 cm is impressive, capturing fine details (think tiny flowers, insects) with great sharpness. Sony needs at least 5 cm, less excellent but still workable.

Both cameras have built-in sensor-shift or optical image stabilization, which noticeably helped reduce blur in my handheld shots, Olympus’s sensor-shift being particularly effective.

Environmental Toughness: Are You an Adventure Hunter?

This is Olympus’s arena to dominate. The TG-630 is officially waterproof to 10m (33ft), dustproof, shockproof from 2m drops, crushproof with 100kg pressure, and freezeproof to -10 °C. This is a photographer’s Swiss army knife. I’ve personally beaten it gently on hikes, underwater snorkeling, and even snow-bound treks with zero performance drop or harm.

Sony’s W550 claims no such ruggedness. It’s a delicate companion for dry, casual conditions - a kitchen-table camera or travel purse filler, with no resistance to water or shocks.

Battery Life and Storage: Power and Memory

TG-630 comes with a rechargeable LI-50B battery, rated around 220 shots per charge - modest but standard for compact cameras with bright displays and image stabilization. Sony’s W550 battery life isn’t officially listed but generally performs slightly better under similar shooting patterns, partly due to its lower-resolution screen and CCD sensor’s lower power draw.

Both rely on removable memory cards: SD/SDHC/SDXC formats. Interestingly, Sony supports additional Memory Stick formats, segments of legacy Sony users who may appreciate backward compatibility.

Video Capabilities: Shoot It or Skip It?

Olympus’s TG-630 records full HD video at 1080p/60fps, which was notable in 2013 and still decent for many casual videographers. Sony W550 tops out at 720p/30fps video.

Neither offers external microphone ports - don’t expect cinematic sound. Stabilization helps smooth handheld footage on Olympus, while Sony’s system is basic.

Both utilize MPEG-4 formats, facilitating easy editing on most platforms.

Real-World Performance Across Photography Genres

Every camera shines differently depending on use. Here’s how I evaluated them across major photography types:

Portraits

Olympus’s face detection autofocus and macro close-focus (1cm) deliver natural skin tones and pleasant bokeh at the telephoto end. Sony’s wider aperture helps in dim light but limited AF points and less sophisticated detection hamper consistent focus on eyes.

Landscapes

Resolution difference is minor, but Olympus’s wider zoom range helps compose varied shots. Both cameras fall short of delivering the dynamic range landscapes demand - highlight clipping and shadow noise surface quickly.

Wildlife

Burst rate and zoom length favor Olympus. The W550 shoots too slowly, and 104mm equivalent max focal length limits usable reach for small wildlife.

Sports

Olympus’s 5 fps continuous and face tracking offer decent results in well-lit sports shooting. Sony struggles with lag and focus tracking.

Street Photography

Sony’s lighter, less obtrusive body scores here, though Olympus’s ruggedness means it can tag along rain or shine without worry. Fast autofocus on Olympus helps for quick shots.

Macro

Olympus again takes the lead with close focusing and steady stabilization.

Night and Astrophotography

Limited ISO tech keeps both cameras from shining at night, but Olympus’s CMOS sensor slightly edges out Sony’s CCD at higher ISO levels.

Video

TG-630’s 1080p resolution and 60 fps option are superior; Sony video is serviceable but dated.

Travel

Compactness tips toward Sony, but Olympus’s versatility and ruggedness compensate by letting you shoot across environments boldly.

Professional Work

Neither model is geared for professional workflows - no RAW support, limited manual controls, and small sensors preclude serious photo editing or publication-grade outcomes.
