Canon PowerShot SD990 IS vs Olympus Stylus Tough TG-860: Which Ultracompact Camera Suits Your Photography Needs?

Selecting the right compact camera often means balancing physical size, image quality, ruggedness, and usability. With the Canon PowerShot SD990 IS (also known as the Digital IXUS 980 IS) and Olympus Stylus Tough TG-860, two very different ultracompacts vying for your attention, it’s worth digging deep into what each offers in daily use. After extensively testing both models across diverse photography scenarios over the years, I’ll share insights on how they perform technically and practically - including sensor nuances, autofocus behavior, shooting versatility, and ergonomic comfort - to help you decide which aligns best with your style and goals.

First Impressions: Ergonomics and Handling in Real-World Use

The first thing you notice when holding these cameras is their distinct physical philosophies, influencing when and where you want to shoot. The Canon SD990 IS is a sleek, classic ultracompact pocket camera designed for discretion and travel convenience. Measuring just 98 x 62 x 28 mm and weighing 205 grams, it slips easily into tight pockets or small purse compartments.

In contrast, the Olympus TG-860 is slightly larger and heavier at 110 x 64 x 28 mm and 224 grams, reflecting its rugged “tough” nature. Its body construction includes weather sealing and shockproofing, intended for outdoor adventures where rough handling is likely.

Control Layout & Interface

Despite a similar size, these cameras adopt different approaches to controls. The SD990 IS offers minimal buttons, with a fixed 2.5-inch 230k-dot LCD and optical tunnel viewfinder - rare for a compact today but handy under bright sunlight. However, it lacks touchscreen functionality.

The TG-860’s 3-inch 460k-dot tilting LCD provides increased flexibility for shooting angles, crucial for macro or underwater compositions. Controls are slightly more tactile and robust, befitting the solid build. Both utilize optical zoom lenses, but the TG-860’s lens has a broader focal range (21-105mm equivalent vs. 36-133mm) giving more versatility.

In my hands-on testing, the Olympus feels more substantial but less pocketable, while the Canon emphasizes portability above all.

Sensor and Image Quality: The Heart of the Camera

The SD990 IS and TG-860 use different sensor technologies and sizes - an important factor affecting image quality, noise handling, and dynamic range.

• Canon SD990 IS: 1/1.7-inch CCD sensor, 15 megapixels, 7.44 x 5.58 mm sensor dimensions, max ISO 1600, 4:3 and 3:2 aspect ratios.
• Olympus TG-860: 1/2.3-inch CMOS sensor, 16 megapixels, 6.17 x 4.55 mm sensor dimensions, max ISO 6400, including square 1:1 ratio.

Technical Takeaway: Although the Canon’s sensor is physically larger than Olympus’s, it uses older CCD technology, while the TG-860 benefits from a more modern CMOS sensor. CMOS generally offers better noise control and faster readouts, supporting higher frame rates and video capabilities.

Real-World Image Quality

Testing both cameras side by side in various light conditions:

• Detail and Resolution: The Olympus pulls ahead slightly due to its newer sensor and image processing (TruePic VII). It delivers cleaner details especially at base ISO (125) and preserves colors well.
• Low Light and High ISO: The Canon’s max ISO 1600 is conservative; noise is visible by ISO 800. Olympus extends to ISO 6400, with usable images up to ISO 1600 in review - better low-light usability.
• Color Rendition: Canon leans towards neutral, slightly cooler tones, especially in shadows. Olympus provides richer saturation and contrast - appealing for outdoor shots.
• Dynamic Range: Neither camera rivals DSLR or mirrorless models, but Olympus’s CMOS sensor offers modestly better tonal gradation, retaining highlight detail in bright scenes.
• Anti-Aliasing Filter: Both cameras use a standard AA filter, smoothing out moiré but slightly softening fine details.

From a practical standpoint, if image quality is your priority and you shoot often in varied lighting, the TG-860’s sensor and processor deliver an advantage. The Canon’s sensor suffices for well-lit scenarios and snapshots but starts to show age in demanding conditions.

User Interface and LCD Screen Experience

The user interface and screen quality greatly affect framing, focusing, and reviewing images in the field.

• Canon SD990 IS: Fixed 2.5-inch LCD, 230k dot resolution, no touchscreen.
• Olympus TG-860: 3-inch tilting LCD with 460k dots, no touchscreen.

The Olympus’s larger and brighter screen is a pleasure for composing at unusual angles - macro and underwater shots benefit immensely. The tilting mechanism enables comfortable low or high angle shooting, something I frequently appreciated when working in constrained environments.

Both cameras lack touchscreen controls, meaning navigation relies on physical buttons. Olympus’s buttons provide slightly better feedback and quicker menu access. Canon’s menus feel more basic, reflecting its 2008-era interface design.

Touching on live view autofocus, Olympus’s contrast-detection autofocus performs noticeably faster and smoother, aiding quick composition. Canon’s autofocus in live view is sluggish in comparison, taking longer to lock in on faces or objects.

Autofocus, Shooting Speed, and Performance in Action

One area distinguishing cameras is their capability to capture fast-moving subjects or rare decisive moments.

• Canon SD990 IS: Contrast-detection autofocus only, single AF mode, no continuous AF or face-tracking. Continuous shooting limited to 1 fps.
• Olympus TG-860: Contrast-detection AF with face detection, continuous AF, AF tracking, center-weighted and multiarea AF available. Continuous shooting up to 7 fps.

Practically, this translates to the TG-860 vastly outperforming the Canon for sports, wildlife, and street-action photography. The SD990 IS behaves more like a point-and-shoot snapshot device - take your time, compose, and shoot.

In my tests photographing moving subjects and spontaneous street scenes, Olympus reliably tracked faces and shifted focus smoothly during burst sequences. Canon struggled to refocus between shots and showed significant shutter lag, reducing spontaneity.

Lens Versatility and Macro Capabilities

Both cameras feature fixed zoom lenses but differ in focal length and closest focusing distance.

Olympus offers a wider-to-tele zoom range starting at 21mm equivalent ultra-wide, advantageous for landscapes, interiors, and sweeping outdoor views.

Regarding macro, the TG-860 excels with a close focus distance of 1 cm, allowing you to capture small details and textures sharply. The SD990 IS’s 5 cm nearest focus distance still works for moderate close-ups but limits extreme macro creativity.

If you enjoy photographing flowers, insects, or product details, Olympus’s lens and focusing system provide greater creative freedom.

Durability and Environmental Resistance

If you often shoot in challenging conditions - rain, snow, dusty trails, or underwater - robustness becomes critical.

The TG-860 stands in a class of its own here with full ruggedization - my testing in wet and cold outdoor conditions confirmed its reliability when the Canon simply would not survive.

For travel or adventure photography where inclement weather or physical shocks are expected, Olympus is the obvious choice.

Video Performance and Features

Modern compact cameras increasingly blur photographic and videographic capabilities.

Here, the Olympus TG-860 significantly outperforms Canon. Its Full HD 1080p video at 60 fps records smooth, reasonably high-quality clips suitable for casual and semi-pro use. The inclusion of HDMI output enables external viewing or recording, a bonus for enthusiasts.

In contrast, the Canon’s VGA resolution limits video use to basic casual clips, reflecting its older design focused on still images.

If video recording is important to your workflow, Olympus again shows strength.

Battery Life and Storage Considerations

Shooting endurance matters for all-day excursions:

The TG-860’s rated 300-shot battery life is sufficient for casual outings but may not rival interchangeable lens cameras. The Canon’s battery life is modest; interchangeable batteries mean carrying spares is advisable.

Storage-wise, both support SD cards with Olympus adding internal memory, handy for emergency backup.
