Canon PowerShot A800 vs Casio Exilim EX-S12: Battle of the Budget-Friendly Compact Cameras

When it comes to entry-level compact cameras on a shoestring budget, the Canon PowerShot A800 and Casio Exilim EX-S12 have stood the test of time as affordable, no-frills options for casual shooters and beginners. Announced in the early 2010s, both models target those who want simple, point-and-shoot usability without breaking the bank. But as someone who’s tested thousands of cameras across all price ranges, I can tell you that not all compacts are created equal - and the devil is really in the details for these two small-sensor compacts.

In this head-to-head, I dive deep into every aspect - from sensor specs and image quality to ergonomics and real-world shooting scenarios - so you can get a clear picture of which camera genuinely suits your style, needs, and wallet.

A Tale of Two Compacts: Physical Size and Handling

Physically, both cameras are pocketable and lightweight, but there are subtle differences that affect how they feel in hand. The Canon A800 is a bit chunkier at 94 x 61 x 31 mm and weighs 186 g, powered by common AA batteries, whereas the Casio EX-S12 is sleeker at 95 x 60 x 23 mm and lighter at 111 g, with a proprietary NP-60 rechargeable battery.

In practical use, the A800's grip offers a more confident hold, especially for folks with larger hands who dislike tiny, slippery bodies. The Casio’s ultra-slim profile is great for stuffing into a purse or jacket pocket, but I found its narrow edges less ergonomic over extended shooting. Plus, the heavier Canon feels a bit more stable, minimizing that annoying camera shake you get when you try to shoot one-handed, especially at telephoto.

The weight and thickness difference also extend to usability; I often prefer a little heft as it lends a natural steadiness - especially useful when you don’t have image stabilization (more on that later).

Design & Controls: How User-Friendly Are They?

Being a compact shooter myself for years, I always emphasize how intuitive camera controls are for beginners and casual users. The Canon and Casio both embrace simplicity but differ on layout and usability.

Looking down from above, the Canon A800 sports clearly labeled buttons and a well-sized mode dial that doesn’t feel like juggling clubs for your thumbs. Its control scheme focuses on basic modes (auto, scene selections) and straightforward navigation, which aligns well with a first-timer’s mindset.

The Casio EX-S12 is more minimalistic, consolidating options into fewer buttons, but frustratingly, some essential functions get buried under menus. The lack of tactile feedback on some buttons means that in low light or quick-shoot situations, it can feel a bit fiddly. Notably, the EX-S12 offers manual focus - a surprise at this level - but navigating it is tedious without dedicated dials.

Neither camera has touchscreens or electronic viewfinders, which you might expect at this price, but the Canon’s 2.5-inch 115K-dot LCD feels dimmer and lower-res than Casio’s brighter 2.7-inch 230K-dot panel.

In daily use, that brighter Casio screen makes a difference when composing outdoors, though neither display excels in sunlight. From an ergonomic standpoint, the Canon’s buttons are easier to press and more logically placed, which means less frustration during casual shoots.

Sensors and Image Quality: Small Sensors with Big Compromises

Here’s where these compacts meet their biggest challenges: tiny 1/2.3-inch CCD sensors with limited physics - and that’s a polite way of saying image quality is never going to rival larger-sensor cameras (DSLRs or mirrorless). Still, within their category, differences emerge.

The Canon packs a 10-megapixel sensor, while the Casio pushes that to 12-megapixels. On paper, that sounds like a Casio win. But pixel count means less than you might think here - sensor size and quality count more.

Both sensors measure approximately 6.17 x 4.55 mm offering an active area of around 28 mm². Their CCD nature delivers respectable colors and resolution for web and casual print, but suffers in dynamic range and low light.

In controlled tests, images from both cameras show typical small-sensor issues:

• Noise at ISO 400 and above becomes apparent, with the Canon surprisingly maintaining slightly smoother grain compared to the Casio at ISO 800 and 1600.
• Dynamic range is very limited; highlights clip aggressively, especially in scenes with both bright skies and shadows.
• Color depth shows moderate saturation but leans somewhat towards cooler tones on the Canon, while the Casio renders warmer skin tones.
• Sharpness is constrained by their simple lenses and anti-aliasing filters, leading to soft edges wide open.

In practical shooting, I recommend you keep ISO low (80-100 native on Canon, 100 on Casio) and expose carefully to avoid highlights clipping.

Autofocus and Speed: How Snappy Are They?

Compact cameras notoriously lag behind DSLRs in speed and autofocus performance, and these two small-sensor hunters are no exception.

The Canon A800 offers 9 focus points with contrast-detection AF and face detection, while the Casio EX-S12 uses contrast-detection AF with no face detection and only single-point autofocus.

The Canon’s face detection feature is a small boon for portrait shooters seeking to nail focus on eyes, especially in casual snapshots. However, its AF speed is modest - focus acquisition took about 1.5 seconds in good light and longer under low contrast or dim conditions.

The Casio’s autofocus is slower and more prone to hunting. Manual focus is an available workaround - rare and appreciated in this class - but difficult without dedicated controls.

Continuous shooting is another area where the Canon edges out, capping at 1 fps under burst mode (slow by modern standards), while the Casio doesn’t offer continuous shooting options.

Lens Performance and Versatility: Fixed Glass Here, Friend

Neither camera has interchangeable lenses; their fixed zoom lenses offer limited focal reach:

• Canon A800: 37-122 mm equivalent (3.3x zoom), max aperture f/3.0-5.8
• Casio EX-S12: 36-108 mm equivalent (3x zoom), max aperture f/2.8-7.9

The Canon’s slightly longer reach at the telephoto end is a bonus for casual wildlife or candid portrait composition, though both lenses close down fast at longer focal lengths, limiting low-light utility.

The Canon boasts a very close macro focus distance of around 1cm, allowing for compelling close-ups of flowers or small objects - a nice edge over the Casio which doesn't specify macro focusing.

Neither lens includes image stabilization, which heavily impacts everyday shootability, especially at longer zoom or in low light.

Shooting Modes & Features: Simplicity Over Sophistication

In terms of exposure modes, neither camera offers manual control, aperture priority, or shutter priority - they rely on fully automatic shooting or basic scene modes. The Canon includes exposure compensation and custom white balance; the Casio offers custom white balance but no exposure compensation.

Both models provide built-in flash with limited range (Canon’s flash reaches approx 3 meters), helpful in close quarters but prone to harsh lighting.

White balance options are useful for daylight tweaking, but without RAW support on either camera, fine post-processing flexibility is minimal.

Video Capabilities: Not Designed for Videographer Dreams

Both cameras support low-resolution video modes:

• Canon A800 tops out at VGA (640 x 480) at 30fps
• Casio EX-S12 offers HD 720p at 24fps

Neither supports external microphones or headphone outputs, and both record Motion JPEG, an inefficient codec producing large file sizes with modest quality.

If video is on your radar for vlogging or content creation, the Casio’s HD mode is modestly better but still falls behind even mid-tier modern smartphones in quality and features like stabilization.

Battery Life and Storage: Practical Considerations

The Canon’s use of 2x AA batteries is a double-edged sword; AA batteries are easy to find anywhere - a plus for travel or emergencies - but tend to weigh the camera down and aren’t as long-lasting as proprietary lithium packs.

The Casio EX-S12’s NP-60 rechargeable lithium-ion battery keeps the weight down but requires you to have the charger handy. Unfortunately, official battery life specs are missing, but typical usage suggests around 200-250 shots per charge.

Both support SD/SDHC cards for storage.

Connectivity and Extras: Minimal, but Casio Offers a Touch of Wireless

Neither model offers Bluetooth or NFC, but the Casio EX-S12 is “Eye-Fi connected,” meaning it can work with Eye-Fi SD cards for limited wireless transfer (a feature popular a decade ago, now largely obsolete).

The Canon lacks this, relying solely on USB 2.0 for transferring images.

Real-World Photography with These Budgets Guns

Now, how do these specs translate into the kind of photography you might enjoy?

Portrait Photography

Both cameras shoot decent casual portraits under good light, but the Canon’s face detection autofocus improves sharpness on faces, especially eyes. Skin tones look more neutral, while Casio’s warmer renditions might be a stylistic choice.

The Canon’s wider aperture at the short zoom range produces softer backgrounds, rendering a bit of bokeh - albeit modest, given small sensor size.

Landscape Photography

Neither camera lets you control aperture, limiting depth of field creative control. The Canon’s longer zoom helps frame distant landscapes better.

However, the lack of RAW and limited dynamic range means highlights blow out quickly in high contrast scenes. Neither has weather sealing; so outdoor shooting requires care.

Wildlife and Sports Photography

For active subjects, both cameras fall short. Slow autofocus and low burst frame rates mean missed moments. The Canon edges slightly with longer zoom and continuous autofocus, but these compacts aren't designed for action.

Street and Travel Photography

For portability, the Casio wins with its slim form, but its limited handling and slower AF may frustrate quick candid shots.

The Canon’s better ergonomics and AA battery option make it more reliable for travelers who want straightforward shooting without worrying about recharging.

Macro Photography

Canon’s 1 cm macro focus distance makes it a fun toy for nature close-ups. The Casio falls short here.

Night and Astro

Both cameras struggle with high ISO noise and have no special astro or night modes; they’re best avoided in low light scenarios.

Image Gallery: Sample Shots Side by Side

For a visual comparison, here are some sample images under varied conditions from both cameras:
