Canon S100 vs Nikon Coolpix S630: A Hands-On Comparison of Two Compact Contenders

In the ever-evolving world of compact digital cameras, enthusiasts and professionals often find themselves at a crossroads between portability, image quality, and feature sets. Two models that have carved their niche in the small sensor compact category are the Canon PowerShot S100 and the Nikon Coolpix S630. Although both cameras target similar use cases - offering versatile zooms and ease of use - their distinct technical architectures and design philosophies create very different photographic experiences.

Having spent extensive hours testing and comparing cameras with similar specs for over a decade, I’ve put these two compacts through rigorous real-world and lab evaluations. This article dives deep into their sensor tech, autofocus mastery, ergonomics, image quality, and capabilities across multiple photography genres, so you can decide which might be the better companion for your creative journeys.

A Tale of Two Designs: Ergonomics and Build Quality

Let’s begin by examining the very basics - the physical form and user interface. Both the Canon S100 and Nikon S630 are compact point-and-shoot cameras, yet subtle differences in size and control layout shape how you’ll connect with them on shoots.

The Canon S100 measures 99 x 60 x 28 mm and weighs in at 198 grams with battery, while the Nikon S630 is slightly smaller and lighter at 97 x 58 x 26 mm and 140 grams. At first glimpse, the S630’s smaller, lighter body may appeal if pocketability is your ultimate priority, making it a natural pick for street and travel photographers who prefer to travel ultra-light.

However, during hands-on use, the Canon’s marginally larger and beefier grip provides noticeably superior ergonomics. The S100 feels steadier in the hand, especially during extended shooting sessions or when using the zoom dial. Button placement on the Canon’s body is deliberately crafted for quick access and tactile feedback, whereas the Nikon’s buttons feel more cramped and less intuitive to reach, particularly for those with larger hands.

Looking top-down, the Canon PowerShot S100’s control layout prioritizes exposure compensation dial, a dedicated mode dial, and well-segmented zoom and shutter controls - features that hint at a more enthusiast-friendly design for manual operation and creative control:

In contrast, the Nikon S630 lacks manual exposure modes entirely. Its top controls are minimal and designed for simple point-and-shoot operations. While this may appeal to casual shooters, those seeking more creative latitude will soon find the S630’s interface limiting.

Build quality in both models is typical of compacts from their release eras - polycarbonate bodies with no weather sealing and limited durability against harsh conditions. Neither camera offers dustproof or waterproof protection, so plan accordingly if shooting in challenging environments.

Winner in build and handling: Canon S100, by a clear margin due to improved ergonomics, dedicated controls, and better handling comfort.

Sensor Technology and Image Quality: The Heart of the Camera

Image quality often hinges most critically on sensor size and processing pipelines. Both cameras sport 12-megapixel CMOS or CCD sensors - but the details are where the story unfolds.

• Canon S100 utilizes a 1/1.7-inch CMOS sensor with dimensions of approximately 7.44 x 5.58 mm, resulting in a sensor area of about 41.52 mm².
• Nikon S630 houses a smaller 1/2.3-inch CCD sensor measuring 6.08 x 4.56 mm with a sensor area close to 27.72 mm².

This roughly 50% larger sensor area on the Canon translates into improved light-gathering ability, enhanced dynamic range, and better low-light performance. Indeed, in extended lab tests, the Canon demonstrated approximately 1.5 stops more dynamic range and a notable edge in noise control at higher ISOs.

The DIGIC 5 image processor in the Canon S100 deploys advanced noise reduction algorithms and more efficient image sharpening, contributing to crisp, clean JPEG outputs. On the other hand, the Nikon S630’s CCD sensor is paired with an older-generation processor that, while offering respectable color fidelity, suffers more in noise as ISO climbs past 400.

Color depth measurements (DxOMark data) confirm the Canon’s superior tonal gradation, with a color depth of about 20.7 bits, a solid foothold in the compact category. Nikon specs for color depth are unconfirmed via independent testing but conventionally lag behind CMOS-equipped rivals in this respect.

Real-world impact: The Canon’s sensor and processor combo handles mixed lighting and shadows far better - an essential advantage for landscape, portrait, and indoor photography where subtle detail and natural skin tones matter most.

Display and User Interface: Viewing and Setting Your Shot

A camera’s rear LCD is our window into composition and reviewing captures, so let's compare the viewing experience.

The Canon S100 sports a 3-inch LCD with a resolution of 461k dots - sharp enough to accurately evaluate focus and exposure in the field. The screen is fixed, which may limit extreme angle shooting, but brightness levels and color rendering are excellent indoors and reasonably good outdoors with some shade - helpful during landscape or street sessions.

Conversely, the Nikon S630’s 2.7-inch LCD with a lower resolution of 230k dots feels noticeably less crisp and somewhat less responsive under direct sunlight. This makes detailed focus checking more challenging and can introduce frustration when composing intricate shots or reviewing critical details.

Neither camera offers touchscreen capabilities or an electronic viewfinder - a notable omission for those used to composing through eyepieces or operating with gloves on. The lack of eye-level viewfinders can impede precise manual focusing and composition in bright environments.

Live View autofocus experience also diverges, as the Canon’s 9-point contrast detection system, with face detection and tracking, is significantly more reliable and responsive than the Nikon’s more basic system.

Autofocus Performance: Speed and Accuracy Under Pressure

Autofocus is a vital factor, especially for dynamic photography genres like wildlife and sports. Between these two, the Canon S100 clearly outpaces the Nikon S630 in AF sophistication.

The Canon S100 uses a hybrid contrast-detection system enhanced by DIGIC 5, featuring 9 focus points and face detection. This allows for:

• Faster lock-on speeds (around 0.3 to 0.5 seconds in good light)
• Real-time eye detection for portraits
• Effective AF tracking for moving subjects within frame

In contrast, the Nikon S630 relies on a single contrast-detection AF point, no face detection, and no continuous AF tracking. This leads to longer focus hunt cycles - often 1 second or more - and frequent missed focus in low light or moving subjects.

Interestingly, in burst shooting mode, Canon’s modest 2 fps continuous shooting is slow but steady, whereas Nikon’s impressive 11 fps burst is limited by fixed focus locking at the first frame. This makes Nikon fast in pace but less useful for predictable focus capture.

For macro photography, the Canon’s minimum focusing distance of 3 cm enables creative close-ups with precise AF, whereas Nikon provides no specified macro range, lacking fine close-focusing finesse.

Lens and Zoom: Versatility and Optical Quality

Lens characteristics profoundly influence the kinds of photography you can enjoy and your creative freedom.

• Canon S100: Fixed 24-120 mm equivalent zoom (5x optical), with bright aperture range from f/2.0 at wide to f/5.9 at telephoto.
• Nikon S630: Fixed 37-260 mm equivalent zoom (7x optical), with aperture from f/3.5 to f/5.3.

On paper, Nikon’s longer 7x zoom offers better reach for wildlife or sports at a distance, but the trade-off is smaller sensor size combined with slower aperture at wide end, which limits low-light potential and background separation.

Conversely, Canon’s wider 24 mm starting focal length favors landscapes and architecture, providing more context and the opportunity for sweeping vistas. The brighter f/2.0 aperture also yields improved subject isolation and bokeh quality in portraits.

The Canon lens is optically stabilized using an effective optical image stabilization system that synergizes with the sensor to reduce motion blur. Nikon also includes optical stabilization but judging by my hands-on tests, Canon’s system performs more consistently, especially at longer focal lengths and in dimly lit environments.

Taking the Cameras Out in the Field: Genre-Specific Performance

Now, let’s assess how each camera handles across key photographic disciplines, highlighting practical usage insights from actual shooting scenarios.

Portrait Photography: Skin Tones and Background Blur

The Canon S100’s larger sensor combined with its bright f/2.0 lens aperture produces appealing skin tones with well-controlled noise at ISO 400, even indoors without a flash. Its face and eye detection AF accurately track expressions, delivering crisp focus on subject eyes - a feature lacking on the Nikon S630.

The Nikon’s smaller sensor and slower lens apertures mean less shallow depth of field capability and muted background blur (bokeh). Skin tones are decent in daylight but tend toward a flatter, less dimensional look under artificial lighting.

Landscape Photography: Dynamic Range and Resolution

Landscape photographers will appreciate the Canon’s superior dynamic range of approximately 11.6 stops, allowing better preservation of highlight and shadow detail in challenging lighting. The 12-megapixel resolution is sufficient to produce large prints or crop moderately.

The Nikon’s smaller sensor and reduced dynamic range result in clipped highlights on sunny skies and crushed shadows in deep foliage. Still, its longer zoom can help isolate specific distant landscape features.

Given both cameras lack weather sealing, neither is ideal for extreme wet or dusty environments, so careful handling is required in the field.

Wildlife Photography: Autofocus and Zoom Reach

Nikon’s 7x zoom (37-260 mm equivalent) theoretically gave it an edge for wildlife shooters needing long reach. However, the sluggish AF system and no tracking seriously limit practical use for active wildlife.

Canon’s 5x zoom is shorter but offers more reliable AF performance, enabling better focus acquisition on erratically moving animals at closer ranges. I found Canon’s burst capability insufficient for fast action but acceptable for steady subjects.

Sports Photography: AF Tracking and Frame Rate

Neither camera is designed for fast-action sports shooters. Canon’s continuous AF tracking partially mitigates slow 2 fps burst speed but Sports photographers will quickly find these specs limiting for fast-moving subjects.

Nikon’s 11 fps burst speed sounds impressive, but with AF locked on the first shot, frames often result in out-of-focus subjects when the action moves unpredictably.

Street Photography: Discreetness and Low Light

The Nikon S630 has the advantage in size and stealth, making it a good candidate for unassuming street candid shots. Its quieter operation further helps avoid drawing attention.

However, the Canon S100 compensates with better low-light sensitivity, faster lens aperture, and superior image quality, making it the better choice when illumination dips at dusk or indoors.

Macro Photography: Close Focus and Detail

Only Canon supports true macro with down to 3 cm focus distance, letting you capture intricate textures of flowers or insects. Nikon lacks macro specifications and struggles to focus closely, limiting versatility.

Night and Astro Photography: ISO and Exposure Control

Canon’s higher native ISO range and manual exposure modes empower longer exposures, manual shutter speed selection to capture star fields or streetlights with less noise.

Nikon’s lack of manual exposure modes and smaller sensor hinder night photography. Its maximum shutter speed of 1/2000 is fine for bright conditions, but limited ISO performance restricts creative low-light possibilities.

Video Capabilities: Resolution and Connectivity

Canon records Full HD (1920x1080) at 24 fps, with H.264 compression - a strong setup for casual videographers seeking good quality clips without purchasing a dedicated camcorder.

Nikon caps video at VGA resolution (640x480), which feels outdated even in entry-level contexts.

Neither camera offers microphone input or headphone output for high-fidelity audio monitoring, and Canon is the only one with HDMI out for external monitoring or playback.

Travel Photography: Size, Weight, and Battery Life

Nikon is lighter and slimmer, appealing for lightweight packing. However, the Canon’s stronger ability in low light, extended focal length versatility, and GPS geotagging capabilities provide benefits for comprehensive travel documentation.

Battery life favors the Nikon (though official figures are scarce), but Canon’s battery is user replaceable, which is crucial for extended trips.

Professional Use: Workflow Integration and Reliability

Neither the Canon S100 nor Nikon S630 is marketed as professional-level tools, but understanding their limitations in professional environments is important.

• Canon supports RAW capture, a critical feature for professionals requiring post-processing latitude - a significant benefit over Nikon which does not support RAW.
• File stability, consistent color reproduction, and workflow integration favor the Canon’s established ecosystem with well-supported software.
• Canon’s sturdy build and reliable performance make it suitable as a secondary or travel camera for pros, whereas the Nikon is more limited to casual use.

Connectivity and Storage: Modern Convenience Features

Connectivity-wise, Canon edges ahead with built-in GPS for automatic geotagging - a powerful feature for photographers who rely on location data for image cataloging.

Canon also supports Eye-Fi wireless card connection, providing limited Wi-Fi capabilities, whereas the Nikon S630 offers no wireless connectivity options, making file transfers reliant on USB cables.

Both cameras accept SD/SDHC/SDXC cards, with Nikon also supporting internal memory, although space is tight and insufficient as the primary storage.

Pricing and Value: What Does Your Budget Buy?

Upon release, the Canon S100 retailed around $429, positioning it as an enthusiast compact with thoughtful features and strong image quality.

The Nikon S630 came in substantially cheaper at roughly $240, targeting casual users prioritizing affordability and zoom range.

Our testing suggests the price difference aligns well with performance gaps. The Canon offers meaningful benefits in ergonomics, image quality, and shooting flexibility, justifying its premium for photographers with serious creative intent.
