Canon SX170 IS vs Casio EX-ZR800: An Expert’s Take on Two 2013 Small-Sensor Superzooms

In the realm of compact superzoom cameras from around 2013, the Canon PowerShot SX170 IS and the Casio Exilim EX-ZR800 stand out as popular choices for enthusiasts craving versatile focal range in a pocketable form. Both sport 16MP 1/2.3" sensors, extended zoom lenses, and handy automatic features - but which one’s really the better buy for different photographic pursuits in today’s evolving market? Having tested thousands of cameras over the years, I’ll peel back the specs and dive deep into actual handling, image quality, and feature sets, giving you a detailed yet accessible side-by-side assessment.

Let’s uncover not just the data sheets, but how these cameras hold up for photographers seeking solid performance across portraits, landscapes, wildlife, sports, street, macro, night scenes, video, travel, and even professional workflows.

Getting a Feel for It: Design, Dimensions, and Handling

Before you judge a camera by its sensor, you’ll want one that feels good in hand during long shooting sessions. After a week of field testing both, the physical distinctions are immediately obvious.

The Canon SX170 IS is chunkier, measuring roughly 108x71x44 mm and weighing 251 grams. The more slab-sided body feels solid but somewhat bulky, reflecting typical Canon ergonomics with a generous grip that prevents slips. Meanwhile, the EX-ZR800 is more compact at 108x60x31 mm and edges lighter at 222 grams. Casio’s slender dimensions and smoother curves make it snappier to slip into a jacket or small bag, a boon for discreet street or travel shooting.

When shooting handheld for extended periods, I preferred the SX170 IS thanks to the firmer grip and larger buttons that feel more deliberate under the fingers - especially if you’re wearing gloves or want to adjust settings on the fly. The Casio’s tighter button layout and thinner form factor feel a tad cramped, which might slow quick manual tweaks. Granted, this comes down to personal preference, but I’d give a slight edge to Canon’s handling comfort.

Speaking of controls...

The Canon’s top plate boasts a clear mode dial with dedicated manual, aperture, and shutter priority modes - a feature more enthusiast-oriented than many compacts of this era. The EX-ZR800, while sporting shutter and aperture priority too, relies more heavily on automated modes and scene presets, suggesting a gentle lean toward casual users.

Although both cameras lack viewfinders, the Canon relies purely on the rear LCD for composing, as does the Casio, meaning bright daylight shooting will challenge both to some degree.

Inside the Image: Sensor and Image Quality Analysis

At the heart of any camera’s photo quality is its sensor and processor. Both models share a 1/2.3" sensor size (exactly 6.17 x 4.55 mm sensor dimensions), and both capture 16MP stills at a maximum resolution of 4608x3456 pixels. However, their sensor technologies differ notably.

The Canon SX170 IS uses a CCD sensor paired with Canon’s DIGIC 4 processor. CCD sensors have traditionally delivered appealing color rendition and noise control at low ISO settings but struggle at higher ISO sensitivities and with power consumption. Canon’s DIGIC 4 processor was top-notch for its time, albeit overshadowed by newer designs in speed and noise management back then.

In contrast, the EX-ZR800 features a CMOS sensor with Casio’s EXILIM Engine HS 3 processor. The CMOS design allows for faster readout, better high-ISO noise handling, and significantly improved video capabilities compared to CCD. The CMOS’s native sensitivity extends up to ISO 3200 (versus Canon’s 1600 max), offering more flexibility in lower-light scenes.

From my practical tests, the EX-ZR800 cratered less noise at ISO levels above 800, making it more forgiving indoors or at dusk, whereas the Canon’s images stopped looking clean after ISO 400 to 800. Detail retention is marginally better on the Canon at base ISO 100, owing to its CCD’s slightly more natural color rendition, but the difference is subtle and may not be noticeable outside of pixel peeping.

In terms of dynamic range, neither camera offers the latitude to compete with larger-sensor compacts or mirrorless models - expect some highlight and shadow clipping in tricky lighting. Still, both perform adequately for casual landscape and travel photographers on a sunny day.

Viewing and Composing Your Shots

How you see and interact with a camera’s image-making process matters. Both cameras lack electronic viewfinders (EVFs), so the rear LCD is your primary window.

Here the Casio’s EX-ZR800 shines, thanks to its “Super Clear TFT” 3-inch LCD displaying at a notably higher 922k-dot resolution. This results in crisper preview images, making manual focusing and exposure adjustments a bit easier, especially under overcast or shaded conditions.

The Canon SX170 IS’s 3-inch LCD is fixed and a bit dimmer, with a 230k-dot resolution, meaning images look grainier on the screen and fine details can be difficult to assess. The lack of touchscreen is a limitation on both models, though not unusual for their generation.

Neither offers tilting or articulating screens, so high- or low-angle compositions require some contortions.

Autofocus and Shooting Speed: Snapping the Moment

Both cameras utilize contrast-detection autofocus systems with face detection capabilities but no phase-detection sensors, limiting autofocus speed compared to hybrid systems in more advanced compact cameras.

The Canon SX170 IS provides basic single AF with center and multi-area focus. It offers face detection but does not support continuous autofocus tracking for moving subjects, which limits its usability for sports or wildlife.

The Casio EX-ZR800 slightly improves with an AF tracking system and continuous AF mode, helping to lock focus on moving targets - not professional grade, but effective for casual action photography.

Let’s talk frame rates:

• Canon SX170 IS shoots roughly 1 frame per second in continuous mode, which is very slow compared to modern standards or the Casio.
• Casio EX-ZR800 can shoot at 3 FPS continuously - better but not blazing fast.

If your primary interest is shooting fast-moving subjects - kids, wildlife, sports - the Casio’s autofocus and burst speed offer tangible advantages.

Lens and Zoom Capabilities: Stretching Your Reach

Both cameras come equipped with fixed superzoom lenses tailored to small sensor formats.

• Canon SX170 IS: 28-448 mm equivalent zoom (a 16x zoom), max aperture f/3.5-5.9.
• Casio EX-ZR800: 25-450 mm equivalent zoom (approximate 18x zoom), max aperture f/3.5-5.9.

Despite similar reach, the Casio’s slightly wider 25 mm focal start endows it with a marginally better wide-angle ability - useful in cramped interiors or sweeping landscapes.

Neither lens has a constant aperture, which narrows light intake when zooming long. Expect slower shutter speeds and increased ISO at full telephoto.

Both lenses offer macro focusing - Canon down to 1 cm, Casio to 4 cm. The SX170 IS’s aggressive close focusing distance means you can get impressively detailed flower or product shots just centimeters away, whereas the Casio needs a bit more room.

Optical image stabilization is present in both, but Casio uses sensor-shift stabilization which tends to be more effective for both photos and video, while Canon implements lens-shift stabilization.

Focusing on Different Photography Styles

Portrait Photography

When shooting portraits, skin tone fidelity, face detection accuracy, and pleasing bokeh come into play.

• Both cameras detect faces, but without eye-detection AF or animal eye AF, focusing precision is average.
• Skin tones on Canon’s CCD sensor come out slightly warmer and more natural - a subtle plus for skin color accuracy familiar to many Canon shooters.
• Casio tends to produce slightly cooler tones but compensates with post-processing sharpening and saturation.
• Both cameras’ small sensors deliver limited background blur; at full aperture and telephoto, some bokeh exists but don’t expect creamy defocus. The EX-ZR800’s lens aperture and sensor-based IS assist in nail-sharp portraits even in lower light.

Landscape Photography

Landscape shooters care about resolution, dynamic range, and weather durability.

• Both produce 16MP JPEGs at 4608x3456 pixels - sufficient for moderate prints and cropping.
• Dynamic range is limited; highlight clipping in bright skies is typical; moderately tricky, so shooting RAW would help, but neither supports RAW output.
• Weather sealing is absent in both, so be wary shooting in harsh conditions.
• Casio edges Canon with slightly better high ISO performance, helpful for twilight landscapes.
• The Casio’s wider 25mm wide-angle offers more expressive compositions.
• Canon’s warm color bias supports classic landscape tones out of camera.

Wildlife and Sports Photography

Here, fast autofocus, continuous shooting speed, and zoom reach are critical.

• Canon’s slow 1 FPS burst rate makes it poorly suited for dynamic subjects.
• Casio’s 3 FPS burst speed and AF tracking give it a modest edge.
• Telephoto reach is basically equal, but Casio’s faster AF and IS aid in capturing clearer, sharper wildlife shots.
• Neither camera excels in low light; increasing ISO leads to image noise.
• Sports shooters will find both cameras limiting for fast movements; consider alternatives for professional use, but casual users may manage.

Street Photography

For discreet, quick-shooting street photography...

• The Casio’s smaller size and lighter weight fit street shooting and travel better.
• Slightly faster AF and burst modes help capture decisive moments.
• Both have no viewfinder, so composition via LCD in bright light may frustrate.
• The EX-ZR800’s higher-resolution screen clarifies scenes for framing.
• Both cameras offer silent shutter modes? No - both have mechanical shutters, so neither is truly stealthy.

Macro Photography

• The Canon's 1 cm minimum focusing distance is very impressive, making it a better option for macro enthusiasts on a budget.
• Casio’s minimum focusing distance of 4 cm is decent, but less competitive.
• Stabilization helps here - Casio’s sensor-shift IS is a plus for handheld macro work.

Night and Astro Photography

• Canon’s maximum ISO 1600 and CCD sensor limits noise performance.
• Casio’s ISO 3200 and CMOS sensor (plus EXILIM processor) allow for cleaner images in dark environments.
• Neither camera offers specialized astro modes, but Casio’s timelapse recording is a plus for night time lapse projects.
• Maximum shutter speeds: Canon: 1/3200 sec minimum 15 seconds, Casio: max 1/2000 sec, minimum 4 seconds - so Canon allows longer exposures, favorable if you wish to expose long for stars without bulky accessories.

Video Capabilities

Here’s where the Casio clearly outshines the Canon:

• Canon SX170 IS max video resolution is 1280x720 at 30 fps.
• Casio EX-ZR800 offers 1080p Full HD video at 30 fps, plus slow-motion modes at up to 1000 fps (albeit at extremely low resolutions).
• Casio supports HDMI output; Canon does not - important if you want to do external recording.
• Neither camera has external mic or headphone ports.
• Sensor-based image stabilization on the Casio makes handheld video steadier than Canon’s lens-based.
• Timelapse recording only present on the Casio.

Neither camera offers environmental sealing or splash resistance, so pay attention if you frequently shoot outdoors in adverse weather.

Casio’s lighter plastic body feels less robust than Canon’s denser plastic shell - not a deal breaker but worth noting if durability is a consideration.

Battery Life and Storage

Canon SX170 IS uses NB-6LH battery, rated for approximately 300 shots per charge.

Casio EX-ZR800’s NP-130 battery substantially outperforms with 470 shots per charge in testing - nearly 50% more endurance, making longer days easier without charging.

Both cameras use a single SD/SDHC/SDXC card slot only.

Connectivity and Extras

• Canon supports Eye-Fi cards for wireless photo transfer - handy in its day.
• Casio lacks wireless connectivity.
• Canon lacks HDMI output; Casio includes HDMI.
• Neither has Bluetooth or NFC.

Pricing and Value

At launch, the Casio EX-ZR800 retailed around $429, whereas the Canon SX170 IS was more budget-friendly (retail price around $200-$250 at launch, now often found used or discounted).

Given the Casio’s significantly superior video features, longer battery life, better AF and burst rates, and higher resolution screen, its price premium is justified for enthusiasts seeking more versatile performance.

Conversely, the Canon appeals to buyers prioritizing straightforward still photography with better ergonomics and a slightly more natural color signature at base ISO, on a tighter budget.
