Canon PowerShot A2100 IS vs Casio Exilim EX-ZR800: A Real-World Compact Camera Showdown

When exploring compact cameras, especially in the small sensor category, you quickly realize the diversity in design goals and user demands across models, even within the same class. Today I’m diving deep into two interesting offerings from Canon and Casio - the Canon PowerShot A2100 IS (2009) and the Casio Exilim EX-ZR800 (2013). Both pack a wealth of features but cater to slightly different priorities.

I’ve handled hundreds of compacts from this era and beyond, testing them in my personal workflows and professional assignments. In this comparison, you’ll find a thorough breakdown from sensor technology to ergonomics, and a practical guide to who each camera will best serve - from casual travelers to early enthusiasts building skills in varied photography genres.

Let’s start by sizing up these two contenders.

Physical Size and Handling: Ergonomics Matter

In compact cameras, size, grip comfort, and control layout dramatically impact user experience - especially if you shoot for longer than a handful of minutes or in dynamic environments.

The Canon A2100 IS is noticeably more petite, measuring 102x64x32mm and weighing just 185g (using lightweight AA batteries). Its compactness makes it pocket-friendly but offers less substantial grip real estate, which may affect handling with larger hands or when using extended zoom ranges. The fixed zoom rocker is a bit on the small side, typical for budget compacts.

The Casio EX-ZR800, by contrast, is slightly larger at 108x60x31mm and comes in heavier at 222g with its proprietary battery. This added heft gives it a sturdier feel and better balance with its superzoom lens. The body’s slim profile and subtly textured surfaces help in steady handling, although it’s less pocketable than the Canon.

Between the two, Casio’s ergonomics win if you’re shooting telephoto or need longer sessions without fatigue, whereas Canon’s slim form factors appeal to those who prize portability above all else. Personally, I find Casio’s balance more versatile - a bit like having a camera you can carry all day without strain but still pack in a small bag.

Design and Controls: Keeping Things Under Your Fingers

Ergonomics extend beyond the grip - intuitive control layouts and feedback mechanisms influence your shooting fluidity and speed.

Looking from above, Canon sticks with minimalistic controls with a modest mode dial and a straightforward power/shutter button setup. No dedicated exposure compensation or advanced mode buttons here, reflecting its beginner-friendly orientation. The zoom lever doubles as a control rocker, but manual input options are sparse.

Casio offers a more intricate interface - a mode dial with PASM (Program, Aperture, Shutter, Manual) modes caters to users wanting creative control, plus dedicated buttons for exposure compensation and quick access functions. The shutter button nestles inside a thoughtfully contoured zoom ring, which feels smooth and precise in use.

Neither camera has illuminated buttons or touchscreens - common for the era - but Casio’s higher screen resolution (922k dots) vastly improves menu legibility over Canon’s basic 230k LCD.

For users looking to graduate from snap-and-go to more hands-on experimentation, Casio’s control set is far superior. Canon works well for novices who want simple point-and-shoot operation without distraction.

Sensor and Image Quality: The Heart of the Matter

Now, under the hood, both cameras feature 1/2.3" sensors - the standard small sensor size for compact cameras - but with different underlying technologies and resolutions.

• Canon A2100 IS uses a 12MP CCD sensor.
• Casio EX-ZR800 features a newer generation 16MP CMOS sensor.

CCD sensors are known for pleasing image colors and smooth tonal gradations, while CMOS sensors tend to offer better noise handling and faster readout speeds. Here, the Casio’s higher pixel count means more detail capture, but it comes with the usual trade-offs of smaller photosites potentially impacting low-light performance.

My standardized lab tests reveal the Casio excels in dynamic range and high ISO noise performance, producing cleaner images at ISO 800 and beyond where Canon’s grain becomes quite evident. Canon’s images have a slightly nostalgic warmth and punchy color rendition but fall behind in shadow detail and noise control.

If you’re shooting landscapes or want more flexibility in post-processing, Casio’s sensor satisfies better with its increased resolution and cleaner files. Portrait shooters cherishing classic color tones might find Canon’s CCD aesthetic more agreeable, but the inability to shoot RAW on either model limits professional-grade workflows.

Live View and Display Interfaces

Both cameras lack electronic viewfinders, relying solely on LCD screens for composition - critical on bright days or tricky angles.

Canon’s 3-inch fixed LCD is utilitarian, with only 230k pixels. Colors look washed out, and visibility under strong sunlight requires shading or creative angling. Casio’s 3-inch “Super Clear TFT” display with 922k pixels offers brighter, higher contrast visuals, making framing and menu navigation much easier.

Neither display offers touchscreen inputs or articulation, so shooting at low or high angles can be challenging. While both support live view autofocus, Casio’s AF system is notably faster to lock compared to Canon’s sluggish focusing, crucial for unpredictable subjects.

For quick feedback and precise framing - especially in outdoor conditions - Casio’s LCD wins hands down.

Autofocus and Shooting Speeds: Catch the Moment?

AF performance can make or break dynamic photography like sports, wildlife, or fast street scenes.

• Canon A2100 IS: 9 contrast-detection points, face detection enabled, continuous AF not supported, single shot continuous shooting capped at 1 fps.
• Casio EX-ZR800: Unknown number of AF points but with contrast detection, face detection, center weighted focus, plus AF tracking available, 3 fps burst shooting.

My real-world testing demonstrates the Casio tracks moving subjects with reasonable accuracy and consistency, a surprise for a point-and-shoot. The 3 fps burst, while modest, is usable for casual action sequences.

Canon’s slow 1 fps and no continuous AF make it unsuitable for anything beyond static subjects. Face detection works on both, but Casio’s AF is more reliable and quicker re-acquisition means fewer missed moments.

Wildlife or sports shooters, even at an entry level, will appreciate Casio’s autofocus edge. Casual family snapshot takers or general travel photographers may accept Canon’s simplicity if burst speed and tracking are low priorities.

Zoom Range: Flexibility in Framing

Let’s talk optics - no interchangeable lenses here, so native zoom reach matters.

• Canon A2100 IS offers a 36-216mm equivalent 6x zoom with max apertures of f/3.2-5.9.
• Casio EX-ZR800 boasts a whopping 25-450mm equivalent 18x zoom with f/3.5-5.9 maximum apertures.

The Casio’s lengthy telephoto reach triples Canon’s reach, which opens up wildlife, sports, and travel photography possibilities. Optical image stabilization helps counter handshake at long focal lengths - Canon’s optical IS works well but Casio’s sensor-shift stabilization is slightly more effective from my experience.

However, with longer zoom comes the usual challenges: smaller apertures at the tele end, increased susceptibility to camera shake, and potentially slower autofocus. Casio mitigates some of these with advanced IS and AF tracking modes.

Outdoor and travel photographers requiring zoom versatility will find Casio’s lens a clear knockout, especially when packing light is non-negotiable.

Macro Performance: Closer Look Capabilities

Macro or close-up photography is often overlooked but can be rewarding in a compact camera.

• Canon focuses down to 1 cm in macro mode - impressively close for a compact.
• Casio focuses down to 4 cm - decent but noticeably less intimate.

Canon’s ability allows you to fill the frame with smaller subjects like flowers or insects, enhancing detail capture. Casio offers more convenience with manual focus assistance but its minimum focusing distance limits intense macro shoots.

If macro photography ranks high on your list, Canon’s close focus might surprise you in a good way. Casio remains a generalist here.

Video Features: What’s Under the Hood?

Video remains an essential consideration for many, but these older compacts offer very different experiences.

Canon focuses on basic capture:

• 640 x 480 VGA at 30 fps
• Motion JPEG format (large files, limited quality)
• No external mic, no advanced features

Casio significantly upgrades video:

• Full HD 1920 x 1080 at 30 fps with H.264/MPEG-4 compression
• Slow-motion at various frame rates up to 1000 fps (!) in low resolution
• HDMI out for easy playback
• No external mic inputs - limiting in serious sound recording

Casio blows Canon out of the water on video quality and capability. Those wanting usable video for casual or creative use will appreciate Casio’s versatility and higher resolutions.

Battery and Storage: Powering Your Adventures

Canon relies on 2 AA batteries - a blessing in some ways as these are easily replaced almost anywhere worldwide, albeit at the cost of less efficient power usage. Battery life varies but generally less than modern lithium-ion packs.

Casio uses the NP-130 proprietary lithium-ion battery, rated around 470 shots per charge - respectable but requires spare batteries for extended outings.

Both use a single SD card slot, but Casio supports SDXC, allowing higher capacity storage - crucial given the EX-ZR800’s much larger image and video file sizes.

For casual users or those traveling to remote spots, Canon’s AA batteries offer peace of mind and adaptability. Power users will prefer Casio’s longer-lasting but less universally replaceable lithium pack.

Connectivity and Extras: How Connected Are These Cameras?

Neither camera offers wireless connectivity such as Wi-Fi, Bluetooth, or GPS - not surprising given their release dates.

• Casio edges forward with HDMI output for direct playback on TVs or monitors.
• Canon sticks to basic USB 2.0 data transfer.

None have touchscreens or articulating displays, which limits ease of use in some modern shooting scenarios.

Weather Sealing and Durability: Shooting Into the Elements?

Neither camera features weather sealing, shockproofing, or any ruggedization outright. They’re best kept away from heavy moisture or drops.

If you travel extensively or shoot outdoors frequently, you’ll want to consider protective cases or alternative bodies.
