Canon SX30 IS vs Casio EX-ZR300: A Hands-On Comparison of Two Small Sensor Superzooms

In the vast landscape of digital cameras, the small sensor superzoom category offers an accessible way to cover a wide range of focal lengths without the complexity or expense of interchangeable lenses. Today, I’m diving deep into two noteworthy contenders from the early 2010s - the Canon PowerShot SX30 IS and the Casio Exilim EX-ZR300. Both carved out their niches with distinct strengths, yet they share many baseline characteristics, including 1/2.3" sensors and all-in-one zoom versatility. Through rigorous hands-on testing and careful evaluation, I’ll unpack everything from optics and sensor performance to ergonomics and video capabilities.

Whether you’re a photography enthusiast seeking a budget superzoom or a professional in need of a reliable backup, this comparison will provide the thorough, experienced insight necessary to make an informed decision.

Putting Them Side-by-Side: Size, Build, and Handling

The physical presence and user interface of a camera often define our shooting experience more than pixel counts or lens specs. Handling nuances can make or break spontaneous moments, especially in fast-paced scenarios like street or wildlife photography.

Starting with the Canon SX30 IS, this bridge-style camera takes its cues from DSLR ergonomics. It sits confidently in the hand with a pronounced grip and substantial weight - about 601 grams. The dimensions are 123 x 92 x 108 mm, reflecting its robust build and versatile control layout. This abundance of physical control and a somewhat bulkier form favors photographers who prioritize manual settings and comfortable handling over ultimate portability.

By contrast, the Casio EX-ZR300 is a compact powerhouse, weighing a mere 205 grams and measuring 105 x 59 x 29 mm. The design is minimalist, favoring pocketability and travel-friendly form factors typical of point-and-shoots. This slim profile, however, comes at the expense of an electronic viewfinder - a feature Canon provides but Casio does not.

The difference is stark when you see the two together.

Ergonomic takeaway: Canon offers a DSLR-like feel with a secure grip and more physical controls, ideal for deliberate shooting styles. Casio’s slim design favors casual snapshots and portability but lacks some tactile feedback and the compositional advantage of a viewfinder.

Top Deck Controls and User Interface: Who Wins the Button Race?

Looking at their top layouts provides immediate clues about workflow priorities.

The Canon features a generously sized mode dial, dedicated exposure compensation dial, and a shutter release surrounded by zoom toggle. Buttons are spaced for easy thumb access on the rear and top, speeding up manual mode adjustments. The camera sports a fully articulated 2.7" screen with 230k resolution - functional, though somewhat underwhelming in pixel density by today’s standards.

The Casio makes do without an EVF or dedicated exposure control dials. Its fixed 3" touchscreen boasts a crisp 461k resolution, making it excellent for reviewing photos outdoors. Despite the lack of touchscreen input for setting focus or menus, the LCD clarity does impress, especially in bright lighting.

Here's a visual of their top view control difference:

Interface assessment: Canon’s approach serves photographers who frequently shift between exposure modes and manual adjustments, enhancing creative control. Casio suits users who prefer an intuitive LCD screen for framing and playback but can sacrifice direct button access for a cleaner design.

Sensor Tech and Image Quality: Small Sensors, Big Differences?

Under the hood, both cameras rely on a 1/2.3-inch sensor measuring 6.17 x 4.55 mm (around 28 mm²), which is pretty standard for their class. However, the Canon SX30 IS houses a CCD sensor with 14 MP resolution, while the Casio EX-ZR300 employs a more modern 16 MP backside-illuminated (BSI) CMOS sensor. BSI CMOS technology generally improves low-light sensitivity by allowing better photon capture, an edge Casio holds in theory.

Looking at sensor specs side by side:

When put to practical tests:

• Dynamic range: Casio’s BSI CMOS sensor delivers slightly better dynamic range, preserving more highlight and shadow detail in tricky lighting such as landscapes with bright skies and dark foregrounds.
• Noise and ISO: Casio’s sensor maintains usable detail and lower noise levels up to ISO 800, with gradual degradation at ISO 1600 and above. Canon’s CCD sensor shows more aggressive noise from ISO 400 upwards, making low-light photography more challenging.
• Resolution and detail: Casio’s 16 MP edge pushes slightly crisper images, particularly visible in macro and fine-texture scenarios. However, the difference is subtle and partly mitigated by lens quality.

Conclusion on image quality: If image fidelity, especially in varied light, is critical, Casio’s sensor technology provides a modern boost. Still, with careful ISO management and good lighting, Canon’s images hold their own.

Optical Reach and Lens Performance: Zoom vs Versatility

Canon’s flagship spec here is a staggering 24-840 mm equivalent zoom lens (35x optical zoom), with aperture ranging from f/2.7 at wide-angle to f/5.8 at telephoto.

Casio offers a 24-300 mm equivalent lens (12.5x zoom) with an aperture of f/3.0 to f/5.9.

This difference is significant, particularly for wildlife or sports photographers who rely on long reach.

While Canon’s lens is versatile, the extended zoom range brings compromises in image sharpness and aperture consistency at the telephoto end. Optical stabilization (Optical Image Stabilizer) helps counteract handshake but not subject motion blur.

Casio’s lens, while more modest in zoom, benefits from sensor-shift image stabilization that performs well and lens sharpness that remains surprisingly consistent across the zoom range.

Macro focusing: Casio also edges out with an impressive close-focus distance starting at 1 cm, enabling detailed macro shots with clarity and depth. Canon’s macro range is essentially 0 cm nominally, but in practice, it cannot match Casio’s close-up finesse.

The Viewfinder and Screen Experience: To See or Not to See?

The presence of a quality viewfinder can be a game-changer, especially in bright outdoor conditions.

Canon’s electronic viewfinder - though not remarkably high-res - allows shooting with eye-level stability, shielding the display from sun glare and improving manual focus precision.

Casio entirely lacks a viewfinder, relying solely on the fixed 3-inch LCD.

The fully articulated 2.7" screen on Canon, despite its lower resolution, allows shooting from creative angles such as low or overhead positions - valuable in street and macro photography. Casio’s screen is fixed but packs more pixels for sharper previews and better detail inspection.

Here is how their back screens compare:

Verdict: Canon’s EVF plus articulated screen combo bests Casio’s simpler single LCD for compositional versatility and focus confirmation.

Autofocus Systems and Speed: Eyes on the Prize

Both cameras use contrast-detection autofocus, which naturally lacks the speed and predictive accuracy of modern phase-detection AF.

Canon’s autofocus system offers 9 focus points and can switch between single AF and multi-area AF modes but has no continuous tracking. It performs adequately for static subjects but struggles with fast-moving or erratically moving subjects such as sports or wildlife.

Casio’s autofocus points count is unknown, but it supports AF tracking (albeit restricted in complexity) and provides face detection. However, in real-world use, tracking moving subjects at long zoom and low light can be sluggish.

The burst shooting capabilities also differ starkly: Canon shoots at a modest 1 fps Continuous mode, ideal for deliberate framing but impractical for action sequences. Casio’s highest burst shooting is unspecified, with no continuous burst specification provided, limiting utility for fast sports or wildlife shots.

Video Recording Capabilities: Is There a Winner?

The video stakes have evolved significantly in recent years, but from the specs, we can see that:

• Canon SX30 IS records max video resolution at 1280 x 720 (HD) at 30 fps using Motion JPEG codec, an older and less efficient format, resulting in larger file sizes.
• Casio EX-ZR300 offers 1920 x 1080 (Full HD) at 30 fps using H.264 codec, providing better video quality and smaller file sizes. It also supports slow-motion capture at high frame rates (up to 1000 fps in low-resolution modes) - quite a novelty for its time.

Neither camera offers microphone or headphone jacks, limiting audio control and monitoring options for serious video producers.

Image stabilization during video is active on both, but Casio’s sensor-shift mechanism delivers smoother motion in handheld clips.

Battery Life, Storage, and Connectivity

Canon’s models use the NB-7L battery, but official battery life specifications are vague. In testing, shooting with LCD or EVF results in approximately 200-250 shots per charge under moderate use.

Casio’s NP-130 battery advertises up to 500 shots per charge, a significant advantage for travel and extended shoots without frequent recharge.

Both cameras accept SD/SDHC/SDXC cards, but Casio’s model supports additional MMC variants.

Wireless connectivity is limited exclusively to Eye-Fi card compatibility in both, with no Bluetooth, NFC, or built-in Wi-Fi. USB 2.0 and HDMI outputs come standard.

Portraiture

• Canon: The longer zoom range offers flexibility for tight headshots from a distance. Skin tones remain natural under daylight but sometimes lose warmth indoors due to CCD sensor limitations and less advanced white balance. The 9 AF points help moderately but no eye detection. Bokeh is limited by smaller sensor size and lens aperture.

• Casio: Slightly better color reproduction and face detection AF help capture more pleasant portraits. However, shorter telephoto reach may require close shooting, impacting candid capture opportunities.

Landscape

• Canon: Decent dynamic range rendering but falls short in high-contrast scenes under harsh sunlight due to sensor technology. The articulated screen aids in creative framing.

• Casio: BSI sensor shines here, revealing more tonal gradation and shadow detail. The sharper LCD aids composition though lack of EVF can frustrate in bright conditions.

Wildlife

• Canon: The impressive 840 mm equivalent zoom allows distant subjects to fill the frame. However, slow AF and 1 fps burst severely limit usability for birds or fast mammals. Manual focus remains an option but challenging.

• Casio: Specs favor sharper optics at shorter zoom, but limited telephoto reach restricts wildlife framing. Faster autofocus tracking is a small consolation but handheld shooting stability is better.

Sports

Neither model is optimized for sports.

• Canon: Burst too slow, and AF sluggishness cause many missed moments.

• Casio: Similarly limited, though video options provide alternative capture strategy.

Street Photography

• Canon: Heavier and less discreet but offers greater control.

• Casio: Compact, discreet, fast awake times, and pocketable, making it better suited for street use despite lacking EVF.
