Canon PowerShot S90 vs Canon SD980 IS: An In-Depth Hands-On Comparison for Photography Enthusiasts

When compact cameras first began to incorporate DSLR-style controls and image quality, they became compelling tools for photographers wanting serious capabilities packed into pocketable bodies. Among these, Canon's PowerShot S90 and SD980 IS stand out as lookalikes on paper but with distinct design philosophies and feature sets. Having tested both extensively over years of varied shooting scenarios, I aim to provide an authoritative, experience-driven comparison to guide photographers - whether casual shooters, enthusiasts, or pros seeking a reliable second camera.

This article will dive deeply into all relevant aspects: technical specifications, ergonomics, image quality, autofocus systems, video capabilities, and their real-world performance across diverse photography genres and applications. I’ll share granular insights from my direct hands-on trials, including long-term usage and side-by-side shoots to uncover nuances beyond the spec sheet. Let’s embark on this detailed examination and see which Canon compact fits your photographic style best.

A Tale of Two Canons: Designing Compact Cameras with Different Missions

Both the Canon S90 and SD980 IS belong to the small sensor compact category. Introduced around 2009–2010, they represent Canon’s approach to high-end pocket cameras predicated on accessible form factors with quality optics. They share a Digic 4 processor, CCD sensors, and a host of Canon’s classic image processing algorithms. Yet, their physical design, handling, and core capabilities reveal divergent user priorities.

Examining their size and shapes illustrates this well. The S90 (100 x 58 x 31mm, 195g) is bulkier and heavier but shaped for grip and manual control. It features a classic S-series design, thicker body with a textured grip front and rear, and a range of dials and buttons aimed at experienced shooters who want quick tactile adjustments. The SD980 IS (100 x 53 x 23mm, 150g), by contrast, is more pocketable, slimmer, and lighter, mimicking the stylish, minimalist design ethos of Canon’s Digital IXUS line with a focus on clean lines and simplicity.

Top Controls and Ergonomics: The Photographer’s Interface

I spent ample time handling both cameras side-by-side to see how their control layouts affected shooting fluency.

Canon S90 – Designed for Control

The S90 features a dedicated aperture ring around the lens barrel - a rarity in compact cameras - alongside an exposure compensation dial on top. These tactile controls accelerated my ability to adjust settings on the fly without diving into menus. This camera clearly targets users who understand aperture priority and manual exposure.

Buttons are well shaped and responsive, with minimal lag or ambiguity. I found the shutter release notably pleasant, encouraging decisive shooting. The hotshoe is absent, but Canon’s accessory ecosystem includes adaptors and custom grips.

Canon SD980 IS – Sleek Simplicity

The SD980 IS chose a more streamlined approach. It lacks manual focus control and an aperture ring. Exposure compensation is available but buried deeper in menus. The top panel is mostly smooth with minimal buttons, and while the touchscreen is implemented (a rare and progressive feature at that time), it suffered from sluggish responsiveness and limited multitouch functionality in my hands-on tests.

This camera favors casual or travel shooters who prefer point-and-shoot simplicity over manual control.

Sensor Technology and Image Quality - The Heart of the Matter

While sensor technology has advanced dramatically since these cameras launched, their respective CCD sensors still reveal important differences.

Canon S90’s 1/1.7-inch CCD Sensor

The S90 sports a larger 1/1.7-inch sensor with a 10-megapixel resolution, yielding 3648x2736 max image resolution. The sensor size (approximately 41.5mm²) allows better light gathering than the SD980 IS’s sensor, directly impacting low light performance and dynamic range.

Per DxO measurements, the S90 scores 46 overall, with notable color depth at 20.2 bits and an impressive 11 stops dynamic range. Low light ISO is rated at 185, highlighting respectable noise control for its sensor class and era.

These characteristics translate into cleaner files with smoother skin tones, less digital noise at higher ISO levels, and better preservation of highlight and shadow details - key for portrait and landscape photographers. The S90 fully supports RAW capture, enabling professional-grade postprocessing flexibility I tested thoroughly.

Canon SD980 IS’s Smaller 1/2.3-inch CCD Sensor

With a 12-megapixel resolution (4000x3000 pixels) crammed onto a smaller 1/2.3-inch sensor area (about 28.1mm²), the SD980 IS aims for higher resolution at the expense of increased pixel density and generally reduced light gathering per photosite.

This smaller sensor results in more noise in low-light conditions and less dynamic range, making it less forgiving in harsh lighting or shadow recovery scenarios. RAW support is absent, limiting creative latitude in postproduction. Color depth and dynamic range data are not available from DxO, reflecting its more basic positioning.

Nevertheless, the tighter pixel pitch trades-off with a longer zoom range, making it versatile for telephoto shots during casual outings.

LCD and Live View: An Intuitive Experience?

Viewing and framing photos effectively is critical for any camera, especially compacts without electronic viewfinders.

Canon S90 – Superior Screen Resolution

The S90 employs a 3-inch fixed LCD with a sharp 461k-dot resolution. The screen delivers crisp live view framing, helpful for manual focusing and critical mode adjustments. In bright daylight, I found it sufficiently bright and color-accurate for composing vivid scenes. The lack of a touchscreen is a missed opportunity but doesn’t hinder operation given extensive physical controls.

Canon SD980 IS – Touchscreen and Limitations

The SD980 IS matches the 3-inch size but only offers 230k dots, resulting in a notably softer display. The touchscreen interface is a novel feature for its time, facilitating navigation and touch autofocus point selection. Yet, in practice, the response lag and occasional misreads detracted from smooth operation. The screen’s lower resolution also made it challenging to judge sharpness or fine details, especially in bright sunlight.

Autofocus and Performance: Speed Meets Accuracy

Autofocus speed and precision can make or break photography in fast-moving situations such as wildlife, sports, or street photography. Both cameras use contrast-detection systems with nine focus points.

Canon S90 – Reliable AF for Still Subjects

The S90 autofocus performs competently in good light, locking focus quickly with minimal hunting. However, the contrast detection method means it can struggle in low contrast scenarios or dim conditions. Its lack of continuous AF for moving subjects somewhat limits action shooting.

Unfortunately, face and eye detection are not incorporated; I found manual focus assistance and peaking insufficient, requiring patience for macro or fast-paced portrait sessions.

Canon SD980 IS – Slightly Slower And Less Flexible

The SD980 IS AF system mimics the S90’s nine-point contrast detection array but often felt slower to lock and more prone to focus hunting in my tests. Touch-to-focus helps but doesn’t overcome the inherent sensor limitations.

Neither model supports continuous or predictive AF, limiting both for sports or wildlife photography. For street or casual travel use, AF responsiveness is adequate but not stellar.

Lens and Zoom Range: Versatility Versus Brightness

The optics significantly affect what you can capture beyond sensor performance.

• Canon S90: 28-105mm (3.8x zoom), F2.0–4.9 aperture range
• Canon SD980 IS: 24-120mm (5x zoom), F2.8–5.9 aperture range

The S90’s lens starting at a bright f/2.0 aperture at wide angle allows better light intake, offering shallower depth of field and smoother bokeh in portraits or close-ups. The relatively modest 3.8x zoom still covers a useful focal range with quality optics.

The SD980 IS extends zoom reach to 5x, useful in travel or casual wildlife snaps. However, its smaller max aperture (f/2.8 at wide to a dimmer f/5.9 telephoto) restricts low-light capability and bokeh potential. The faster S90 lens also benefits macro photography with a minimum focus distance of 5cm versus 3cm on the SD980 IS, though SD980’s extra reach compensates for framing flexibility.

Real-World Photography Across Genres

Let me share field experiences using both cameras across diverse scenes to contextualize all these specs with practical relevance.

Portraits

The S90 shines here. Its larger sensor and swift f/2.0 aperture create pleasing bokeh that isolates subjects against softly blurred backgrounds. Skin tones render naturally with fine gradations, aiding flattering portraits indoors and out.

The SD980 IS, while capable of capturing sharp faces, struggles to separate subjects from backgrounds due to higher depth of field and noisier output at indoors ISO. Its fixed lens limits creative framing somewhat.

Landscapes

Dynamic range and detail retention favor the S90, with vivid colors and shadow detail readily apparent in my landscapes shot at golden hour. The SD980 IS produces sharper but slightly noisier images which don’t scale as well in postprocessing.

Lack of weather sealing in both demands caution in rugged shoots, though I compensated by keeping them protected.

Wildlife

Neither camera is a fast-action specialist, but the SD980’s longer 120mm equivalent zoom gave an edge for distant animals in daylight. Conversely, the slower, less responsive autofocus meant many missed moments.

The S90’s brighter lens allowed better low light wildlife captures, but focal length feels limiting.

Sports

Both cameras lack high frame rates or sophisticated AF tracking, falling short for demanding sports. Their single-frame continuous shooting rates capped at 1fps make capturing peak action frustrating. I found these models better suited for casual or behind-the-scenes photography rather than high-octane sports.

Street Photography

The SD980 IS’s slim profile and quiet shutter aided discretion, letting me unobtrusively capture candid moments. The touchscreen autofocus was a boon for quick shooting.

The S90’s thicker body made it less discreet, but manual controls offered creative exposure options for street scenes. Both perform satisfactorily in low light, though the S90’s sensor adds low light headroom.

Macro

Both cameras impress in macro with close focusing of 3-5cm. The S90 benefits from the brighter lens aperture, producing more background blur and sharper fine detail (with careful manual focusing). Image stabilization helped compensate for hand shake at close distances.

Night and Astro

The S90’s maximum ISO 3200 and cleaner output enable longer handheld night shots with less noise penalty. I used it to capture starscapes under clear skies, aided by manual shutter priority mode and optical stabilization.

The SD980 IS maxes out at ISO 1600 with a noisier result, limiting usability in astrophotography.

Video

The SD980 IS surprisingly edges the S90 with HD video recording at 1280×720/30fps alongside standard resolutions. Audio capture is basic with no mic input on either.

The S90 is limited to 640×480 resolution, making it less suitable for today’s video needs. Neither model features advanced video stabilization.

Professional Workflow Compatibility and Connectivity

Neither camera was designed for studio or professional workflows requiring tethering or robust connectivity.

• Both support SD/SDHC cards and output JPEGs (S90 adds RAW support)
• USB 2.0 for data transfer only; no Wi-Fi, Bluetooth, or GPS features
• Neither offers external flash support, limiting off-camera lighting

Battery life is average for compacts of their time, with both sharing the NB-6L battery model but real-world runtimes typically requiring spares for long days.

Durability and Build Quality

Both models lack weather sealing, shockproofing, or freeze-proofing, so use them carefully in harsh climates. The S90’s heavier, robust body felt more durable in my hands, while the SD980 IS prioritizes lightness and elegance but at the expense of a premium feel.

Price and Value: What Do You Get for Your Investment?

At launch, the Canon PowerShot S90 commanded a higher price (~$600) reflecting its enthusiast-grade capabilities. The SD980 IS targeted budget-conscious travelers and casual shooters with a lower price point.

Their market positions remain consistent in the used and refurbished market. The S90 offers greater long-term value for serious photographers seeking manual control and RAW files, whereas the SD980 IS appeals for casual everyday use, especially with its longer zoom and touchscreen.
