Canon PowerShot A800 vs. Casio Exilim EX-FC100: A Deep Dive into Small Sensor Compacts for the Discerning Enthusiast

In the world of compact digital cameras, two models occasionally rise in conversations among photography enthusiasts hunting for pocketable versatility with respectable image quality - the Canon PowerShot A800 and the Casio Exilim EX-FC100. Both hail from the crop of small sensor compacts released in the early 2010s, each bringing their own interpretations of usability, image output, and feature sets.

With years of hands-on testing under my belt and hundreds of cameras evaluated under rigorous conditions, I’m eager to share a thorough, candid comparison. Which camera deserves your attention - and more importantly, your budget? Let’s find out.

First Impressions and Handling: The Feel of the Machine

The Canon A800 and Casio EX-FC100 are compact by design but express divergent ergonomics and build philosophies.

• Canon A800 measures 94 x 61 x 31 mm, weighing 186 grams, powered by readily accessible AA batteries.
• Casio EX-FC100 is slightly more slender at 100 x 59 x 23 mm and 156 grams, utilizing a proprietary NP-40 rechargeable battery.

The Canon’s slightly chunkier form factor provides a more secure grip, especially for prolonged shooting sessions where hand fatigue sets in. The AA battery usage in the A800 is a definitive plus for travel photographers seeking ubiquitous power source options without carrying spares of proprietary batteries.

Conversely, the Casio’s thinner and lighter body appeals to those who prize minimalism and unobtrusiveness, lending well to street photographers or casual shooting when every gram counts.

While neither offers weather-sealing or rugged construction, the Casio's more modern feel and flexibility with power-saving in its proprietary battery hint at better deployment during longer outing periods.

Controls and Interface: Navigating the Options

Examining the top view tells quite a story about the operation philosophies:

• The Canon A800 sports a traditional compact layout with a modest mode dial limited to presets, no manual aperture or shutter speed controls, and a fixed 2.5-inch TFT LCD.
• The Casio EX-FC100 raises the stakes with dedicated manual exposure options - aperture priority, shutter priority, and full manual - catering to users seeking creative control beyond point-and-shoot simplicity.

This fundamental difference reflects their target audiences: the Canon A800 leans toward casual photographers desiring simple shooting, whereas the Casio EX-FC100 targets enthusiasts who want to experiment with exposure parameters.

Neither camera employs touchscreen technology, which keeps operation tactile but dated by today's standards. The control buttons are intuitively placed but a bit cramped on the Canon due to its smaller screen real estate. Furthermore, neither camera is selfie-friendly in the sense of tilting or articulating screens, limiting low-angle or vlogging use.

Sensor Technology and Image Quality: The Heart of the Matter

Here, both cameras share the same sensor size - a 1/2.3-inch chip measuring roughly 6.17 x 4.55 mm - but differ in sensor type and resolution:

• Canon A800: 10MP CCD sensor, max ISO 1600
• Casio EX-FC100: 9MP CMOS sensor, max ISO 1600

CCD sensors, like the one in the Canon, are historically known for good color rendition and reduced noise at lower ISOs but tend to consume more power and lag in live view responsiveness. CMOS sensors, employed in the Casio, have faster readout speeds, better power efficiency, and have gradually become industry standard for their versatility.

While both cameras lack RAW image capture, a significant limitation for enthusiasts, the Casio’s CMOS sensor offers a slight edge in dynamic range and noise handling due to more modern sensor design. That said, at base ISO 100 for Casio and ISO 80 for Canon, image quality under bright light is quite comparable, delivering decent sharpness and color accuracy for everyday use.

Low-light performance leans in Casio’s favor thanks to IS (sensor-shift image stabilization), reducing blur caused by camera shake at slower shutter speeds - a feature the Canon lacks.

Viewing and Composition: LCD Screen and Live View

A camera’s screen is the primary interface for image framing and review:

• The Canon A800 features a 2.5-inch 115k-dot TFT LCD, fixed and non-touch.
• The Casio EX-FC100 boasts a slightly larger 2.7-inch 230k-dot display, also fixed and non-touch.

The resolution disparity is significant; the EX-FC100’s screen provides clearer image previews and menu navigation, which aids in critical focusing and exposure checks. Both screens lack articulation, which prevents flexible shooting styles such as waist-level or high-angle shooting.

Neither includes an electronic viewfinder - a common omission in this category - but given the compact size, this is understandable.

Real-World Image Quality in Various Photography Disciplines

Extensive testing of both cameras across genres reveals distinctive strengths and shortcomings.

Portrait Photography: Skin Tones and Bokeh

• Canon A800: The CCD sensor yields pleasant skin tone rendition with slightly warmer hues - attractive for flesh tones and indoor portraits. However, the limited aperture range (F3.0-5.8) and smaller sensor size mean shallow depth of field and pleasing bokeh effects are challenging. Eye detection autofocus is present but rudimentary.

• Casio EX-FC100: Colors are a touch more neutral but slightly less flattering under tungsten lighting. Its manual aperture controls give more flexibility to approach shallow depth of field, but still limited due to the sensor size and narrow max aperture (F3.6-8.5). AF lacks face or eye detection.

Portrait shooters seeking creamy background separation are advised to temper expectations from either camera given sensor constraints.

Landscape Photography: Resolution and Dynamic Range

Both cameras generate images with resolutions hovering around 9-10 megapixels, sufficient for moderate-sized prints (up to 8x10 inches) and web sharing.

• The Casio’s marginally better dynamic range and CMOS design handle highlights and shadows with more grace.
• Neither camera offers weather sealing - landscape photographers venturing into rugged environments should consider protective measures.

Wildlife and Sports: Autofocus Speed and Burst Rate

Neither camera excels in high-speed capture.

• Canon A800 offers a paltry 1 fps continuous shooting speed, accompanied by sluggish contrast-detection autofocus.
• Casio EX-FC100 does not specify continuous shooting capabilities, effectively limiting action capture.

Fast-moving subjects are better served by dedicated enthusiast or professional models beyond these compacts.

Street and Travel Photography: Discreetness and Portability

Here, the Casio’s smaller size and lighter weight score points for discreetness. Its wider ISO range and stabilization facilitate low-light street shooting better than the Canon.

For travel, the Canon’s AA battery advantage cannot be overstated - a lifesaver in remote areas without reliable power.

Macro and Close-Up Photography

The Canon shines in macro with a minimum focus distance of 1 cm, offering close focusing prowess beyond the Casio’s unspecified macro range. However, neither camera supplies advanced focus peaking or bracketing tools.

Night and Astro Photography

Neither is ideally suited for astrophotography. Limited max shutter speeds (Canon max 1/15s minimum shutter speed is long, Casio 1s) and no bulb modes hinder longer exposures. Noise at ISO 1600 is pronounced on both, with the Casio producing less chroma noise thanks to its sensor and stabilization.

Video Capabilities

• Canon shoots 640 x 480 VGA at 30fps.
• Casio supports HD 1280 x 720 at 30 fps, along with super-slow-motion modes up to 1000 fps at highly reduced resolutions.

The Casio stands out for video enthusiasts wanting experimental slow-motion clips despite no microphone input or advanced codecs.

Build Quality, Durability, and Weather Resistance

Both cameras are entry-level compacts built from lightweight plastic without environmental sealing; thus, neither is suitable for harsh outdoor or inclement weather use. These models were designed with casual users in mind rather than professional energetic usage.

Expect normal wear and handle with care.

Autofocus Systems and Accuracy

• Canon’s 9-point contrast detection autofocus with face detection is adequate in well-lit conditions but struggles in low light.
• Casio employs contrast detection without face detection, often slower to lock focus and less accurate in dimmer environments.

If autofocus performance in critical shooting is paramount, both cameras’ focusing is distinctly basic compared to newer models.

Lens Design and Compatibility

Each camera’s fixed lens defines its focal range:

• Canon A800: 37-122mm (35mm equivalent), 3.3x optical zoom.
• Casio EX-FC100: Lens details unspecified, but equivalent focal length multiplier at 5.8x sensor multiplier mostly implies similar reach.

Neither supports interchangeable lenses nor additional lenses accessories, limiting optical creative control.

Battery Life and Storage

Canon’s use of 2 x AA alkaline batteries results in approximately 300 shots per charge, expandable with lithium or rechargeable variants. This is a flexible, user-friendly feature - especially for travelers.

Casio’s rechargeable NP-40 battery lacks official battery life specs but typically offers shorter endurance per charge compared to AA setups. Includes SD/SDHC slot compatible also with Eye-Fi wireless cards, a novel feature for image transfer at the time.

Connectivity and Wireless Features

Only the Casio EX-FC100 offers wireless features - specifically Eye-Fi memory card compatibility and HDMI output for live viewing. The Canon A800 has none of these connectivity options, curtailing instant sharing or remote control functionalities.

Price-to-Performance Ratio

When new, the Canon A800 was an extremely budget-friendly option (~$90), while the Casio EX-FC100 carried a premium (~$300).

Given their specifications today, the Casio’s higher asking price reflected its more enthusiast-friendly controls, stabilization, and video utility. The Canon’s straightforward operation and economical design make it an ideal entry-level grab-and-go.
