Canon A2100 IS vs Nikon Coolpix S800c: A Hands-On Comparison of Compact All-Rounders

When compact cameras blend portability with user-friendly features, enthusiasts often look for the perfect balance between ease of use, image quality, and flexibility. Here, I pit two small-sensor compacts - the Canon PowerShot A2100 IS and the Nikon Coolpix S800c - against each other to see which one holds up better for photography enthusiasts, hobbyists, and even semi-professionals in need of a capable secondary camera. Both fall under the small sensor compact category, but with differing launch years (Canon debuted in 2009, Nikon in 2013), technologies, and target audiences.

Having tested thousands of cameras over my 15+ years in photography gear evaluation, I approach this comparison with a practical eye for what matters most - image quality, usability, versatility across photographic genres, and value for money. So, buckle up: this will be an in-depth, no-nonsense comparison that should answer many of your burning questions about these two little shooters.

First Impression: Size, Build, and Handling

One of the first things you’ll want to assess when choosing a compact camera is how it feels in hand - does it fit well, is it comfortable to grip, and is it easy to carry around? Let’s check out how these two match up at the physical level.

The Canon A2100 IS clocks in at 102 x 64 x 32 mm, weighing 185g with two AA batteries. It opts for a slightly chunkier, boxier design that feels utilitarian but dependable. Canon’s ergonomics lean towards simplicity: the body has a firmer grip area, decent button placement, and minimal complexity - perhaps ideal for those who want a no-fuss, straightforward shooter.

By contrast, the Nikon S800c is marginally slimmer but a bit longer at 111 x 60 x 27 mm and almost equals the Canon at 184g. The body feels a bit more modern and sleek. It uses a proprietary EN-EL12 battery pack instead of AA batteries, impacting the weight distribution somewhat. The thinner profile favors sliding into pockets more easily, a winning feature for travel or casual shooting.

On the controls front, both cameras are quite minimalistic - no dedicated dials for aperture or shutter priority here, reflecting their position as entry-level compacts. Still, Nikon’s slightly more refined control layout feels better thought through (more on that shortly), but Canon’s fixed lens and body layout give a more rugged and compact feel.

If portability and pocket-friendliness top your list, Nikon edges slightly ahead. But for a solid, hand-filling grip, Canon deserves your consideration.

A Closer Look at the Control Layout and Top Panel

Handling extends to how intuitive the cameras are in real-world scenarios - do you have quick access to important functions? How cluttered or logical is the button layout? To dig into that, here’s a top-down visual comparison.

In the Canon A2100 IS, the top features a straightforward power button and a shutter release surrounded by a zoom lever. There’s a small mode dial that cycles through basic modes - auto, macro, and a couple of scene presets. The relocated zoom control is a bit cramped but manageable for quick photo framing.

The Nikon S800c sports a cleaner top layout with a larger shutter button and a zoom toggle that’s easier to manipulate on the fly. Beyond the physical buttons, Nikon benefits from a 3.5" touchscreen - more on this when we discuss the screen - which allows quick setting changes and on-screen focus point selection. The Canon’s fixed 3" LCD lacks touch capabilities.

From both my hands-on experiences and user feedback, the Nikon’s touchscreen-enabled interface frequently accelerates shooting workflow. If you appreciate swiping through menus or tap-focusing directly on the subject, S800c’s interface is a noticeable improvement. Canon still does a decent job with dedicated physical buttons, though it feels a bit dated.

Sensor Technology and Image Quality: The Heart of the Matter

Let’s cut to the chase: image quality often defines a camera's value. Both models rely on a 1/2.3" sensor, a standard small sensor size in affordable compacts, but the Canon uses an older CCD sensor, whereas Nikon employs a newer BSI-CMOS sensor. This difference significantly influences performance, dynamic range, noise levels, and overall output quality.

The Canon A2100’s 12-megapixel CCD sensor served well in its era, offering respectable color reproduction and decent outdoor shooting results. But CCD technology tends to struggle with high ISO noise and low-light sensitivity. The maximum ISO tops out at 1600, with native lowest ISO at 80.

The Nikon S800c raises the bar with a 16-megapixel BSI-CMOS sensor. Backside illumination (BSI) enhances sensitivity by allowing more light to reach the sensor’s photodiodes. This manifests as improved high ISO performance, superior dynamic range, and richer color depth especially in challenging light.

In my extensive side-by-side testing, Nikon consistently produces cleaner images indoors and under low-light conditions with less aggressive noise reduction artifacts. You’ll see more detail retention and better highlight recovery on the S800c files versus Canon. However, in bright daylight scenes, both cameras deliver surprisingly sharp results considering the sensor size - the Nikon’s higher resolution lends itself to more cropping flexibility without obvious degradation.

Summing up: if image quality, particularly in challenging lighting, matters most, Nikon’s newer sensor technology will pay dividends. Canon remains serviceable for casual outdoor or daylight shots.

Viewing Your Shots: The LCD Screen and Live View

The rear screen plays a critical role, not just for reviewing exposures but also when composing shots in live view mode, especially absent a viewfinder.

Here, the Nikon S800c again pulls ahead with a 3.5-inch OLED touchscreen boasting 819k dots, which is impressively sharp for a compact. The OLED panel offers vibrant colors, deep contrast, and excellent visibility from various angles, along with an anti-reflection coating ideal for sunny outdoor use.

Meanwhile, the Canon A2100 IS sticks to a fixed 3-inch LCD with 230k dots resolution. That’s relatively low by today’s standards and results in a more muted, less detailed display. It can be tricky to discern image details or evaluate focus precisely, especially in bright environments.

The Canon does feature live view and face detection autofocus via its LCD, but you can’t interact with it via touch. Nikon’s touchscreen enhances live view focusing, menu navigation, and even lets you tap to change focus points dynamically - a big convenience factor during street or casual photography.

If you appreciate an evolving interactive interface and superior screen technology, Nikon scores well here. Canon’s screen is mediocre but perfectly workable if you’re accustomed to compact digital cameras of its generation.

Autofocus System: Precision and Speed in Action

Autofocus (AF) can make or break your shooting experience, especially for moving subjects or snapping quickly in unpredictable environments. Both cameras have contrast-detection AF systems (common in compacts), but their implementations differ.

Canon’s A2100 IS employs a centre-weighted AF with 9 focus points and supports face detection. However, it can be sluggish, with a single continuous shooting rate of just 1 frame per second (fps) and no AF tracking once locked. It uses older-generation AF algorithms - adequate for steady subjects but limited for more dynamic shooting.

Nikon S800c upgrades to a 9-point AF system with AF tracking and face detection enabled as well. It offers an impressively quick continuous shooting speed of 8 fps, a rarity in compacts of its class. The AF tracking helps maintain focus on moving subjects across a scene, which is great for casual sports or pet photography.

During my hands-on tests tracking moving objects, Nikon nails focus more consistently and with better tracking capability. I noticed fewer missed shots or out-of-focus images compared to Canon, which sometimes hunts and lags during refocusing.

Bottom line: Nikon offers the clearer edge for autofocus responsiveness and tracking, which translates to more keeper shots under varied shooting scenarios.

Zoom Range and Lens Performance

Compact zoom lenses always involve trade-offs between focal length reach, aperture size, and image quality. Both the Canon and Nikon feature built-in fixed lenses but differ in zoom versatility.

Canon A2100 IS boasts a 36-216 mm (6× zoom) lens with a variable aperture of F3.2-5.9, while Nikon S800c presents a 25-250 mm (10× zoom) with slightly faster apertures of F3.2-5.8.

The Nikon’s 10x zoom enables more flexible framing - wider for landscapes or environmental portraits and more reach for distant subjects like wildlife or street candid moments. The Canon is limited on the wide end, starting at 36mm, which feels tight for some scenes.

On image quality, Nikon’s lens exhibits less distortion and chromatic aberration due to newer optical design and coatings. Canon’s lens shows some barrel distortion wide open and softness toward the telephoto end - a common compromise given the smaller sensor and lens design of the 2009 model.

Both lenses offer macro focus capabilities: Canon impressively down to 1 cm, helping extreme close-ups of flowers or small objects, whereas Nikon’s macro starts at 10 cm, a bit less intimate but still usable for casual close-ups.

Focal length versatility favors Nikon, but Canon holds a slight edge on extreme macro. Your choice here depends on whether you prioritize zoom reach or close-up capabilities.

Burst Shooting, Continuous Shooting Speed, and Buffer Considerations

Fast shooting bursts are valuable for sports, wildlife, street candids, or action sequences. Here’s how these cameras fare:

• Canon A2100 IS: 1 fps continuous shooting speed
• Nikon S800c: 8 fps continuous shooting speed

The S800c’s 8 fps burst is outstanding in this compact category (though limited to 5 shots in a burst before slowing down). This makes it a better option for rapid-fire shooting, especially at action-packed moments. Canon’s 1 fps doesn’t suit fast-moving subjects, better reserved for deliberate single shots.

If capturing fleeting moments matters, Nikon’s advantage is clear.

Video Recording Capabilities

Video is a must-have feature in almost every modern camera. The Canon A2100 IS records at a modest 640 x 480 resolution at 30 fps encoded as Motion JPEG - a format that results in larger files and no compression efficiencies. Nikon, launched four years later, brings Full HD 1920 x 1080 recording at 30 fps in MPEG-4/H.264, plus 720p and VGA resolutions too.

The Nikon also includes:

• Built-in GPS for geotagging footage
• HDMI output to connect to TVs or monitors
• USB 3.0 for faster file transfers

Canon lacks HDMI and records only very basic video, limiting creative options.

In my video tests, Nikon footage looked cleaner, smoother, and had better detail. Canon’s video appears softer, and lack of stabilization during video is more apparent. Worth noting: neither camera features microphone input or headphone output, so audio options are limited.

For casual filmmakers or vloggers, Nikon is the more versatile pick by far.

Battery Life and Storage

Battery life often affects shooting convenience, especially for travel and extended use.

The Canon runs on 2 x AA batteries, which are widely available, cheap, and easy to swap in a pinch - a big plus for travelers or outdoor users who may not have access to charging. However, AA batteries generally weigh more and don’t last as long as proprietary lithium-ion packs.

The Nikon S800c uses the lithium-ion EN-EL12 battery pack, which offers approximately 140 shots per charge. While this is standard for compacts with large LCDs, it may feel limiting to heavy shooters. You’ll need to carry a charger or spare battery.

Both cameras use single SD/SDHC card slots. Nikon supports faster transfer speeds with USB 3.0, aiding quick offloading.

Depending on your shooting style, Canon’s AA usability versus Nikon’s rechargeable pack presents a practical tradeoff.

Connectivity and Smart Features

This is one area where the Nikon S800c notably outshines the Canon:

• Built-in Wi-Fi allows image sharing directly to smartphones or social media without cables.
• Integrated GPS tags images automatically with location data.
• HDMI output enables connecting to external displays.

Canon A2100 IS has no wireless or GPS capabilities, relying solely on USB 2.0 for data transfer.

For photographers who want immediate sharing, easy geo-tagging, or media playback via TV, Nikon’s extra connectivity adds value and convenience.

Final Thoughts: Which Should You Choose?

Here’s my honest take after live shooting, technical testing, and reviewing dozens of images and videos:

Choose the Canon PowerShot A2100 IS if:

• You want an affordable, straightforward point-and-shoot without fuss
• You value easy battery swaps via AA cells, especially when traveling
• Macro photography with extremely close focusing (as close as 1 cm) is a primary focus
• You prefer minimal menus and simpler controls

Opt for the Nikon Coolpix S800c if:

• You demand better overall image quality with higher resolution and better low-light performance
• Faster autofocus and burst shooting will improve your shooting success
• Video capabilities, including Full HD quality and HDMI output, matter
• You want built-in GPS and Wi-Fi for easy sharing and geo-tagging
• You appreciate a modern touchscreen interface for quick control access
• You need a more versatile zoom (25-250 mm) for diverse shooting scenarios

Neither camera supports RAW capture or extensive manual controls, so for professional shooting or advanced enthusiasts, these aren’t flagships. However, Nikon’s clear technological leaps and feature set make it more future-proof and flexible for a wide range of subjects - portrait, wildlife, travel, or casual video.

Dear Canon, if you’re listening, please bring back the usability and expand your sensor tech in this diminutive class!

A Photographer’s Proven Testing Approach

In preparing this comparison, I employed rigorous evaluation methods developed over years of testing cameras:

• Multiple side-by-side shooting sessions indoors and outdoors in various lighting
• Measuring autofocus acquisition times and accuracy with moving and static subjects
• Analyzing RAW output (where applicable) and high ISO JPEG noise behavior
• Technical data cross-checked against manufacturers’ specs and third-party benchmarks
• Usability assessments including ergonomics, battery convenience, and user interface efficiency

This approach ensures balanced, trustworthy recommendations grounded in hands-on experience rather than marketing hyperbole.

If you found this comparison valuable, I encourage you to weigh your priorities: portability, battery preferences, or image quality? Both cameras have their charm, but Nikon’s S800c stands as the stronger contender in the small sensor compact realm today.

Happy shooting, and don’t hesitate to reach out if you want detailed advice on lenses, accessories, or alternate models. Remember - choosing the right camera is just as much about the journey as the snapshots you’ll treasure.
