Canon PowerShot SX700 HS vs. Casio Exilim EX-Z16: A Detailed Analysis of Two Compact Cameras in Distinct Eras

In the realm of compact cameras, distinctions between models can be subtle or stark depending on their intended audience and release period. The Canon PowerShot SX700 HS (2014) and the Casio Exilim EX-Z16 (2010) represent two generations of compact camera technology, designed for casual yet somewhat ambitious photographers prioritizing portability and zoom capability. This analysis systematically compares the two models across critical technical dimensions and usage scenarios, aiming to equip photography enthusiasts and professionals with the necessary insights to make informed decisions.

Understanding the Fundamentals: Build, Dimensions, and Handling

Physical design and ergonomics fundamentally shape user experience in compact cameras. The Canon SX700 HS and Casio EX-Z16 adopt distinctly different form factors influenced by their generation and target use.

The SX700 HS is categorized as a “small sensor superzoom,” embodying a relatively compact body with a substantial zoom lens. Its dimensions measure approximately 113 x 66 x 35 mm, and it weighs 269 grams, including battery and memory card. In contrast, the EX-Z16 is an ultracompact design with approximately 101 x 59 x 20 mm dimensions and an unspecified, but markedly lighter body weight given its ultrathin profile.

The Canon’s larger, thicker body facilitates a more confident grip during extended shooting sessions, especially when telephoto focal lengths increase lens mass and potential camera shake. Conversely, the Casio’s ultra-slim form prioritizes pocketability and spontaneous street shooting, albeit at the expense of handling comfort and extended operational control.

Key observations:

• Canon SX700 HS: Ergonomically preferable for extended wear; button placement tailored for one-handed zoom and exposure adjustments; suitable for users valuing control and superzoom versatility.
• Casio EX-Z16: Ultra-portable and convenient for quick snapshots; minimal physical controls reflecting a simplified user interface; best suited for casual use with prioritization of lightweight carry.

Sensor Technology and Image Quality: BSI CMOS vs. CCD

Sensor architecture significantly influences image quality potential, particularly in low light and high-detail scenarios. Both cameras incorporate similarly sized 1/2.3-inch sensors (~28.07 mm²), which is standard for compact models, but their sensor technologies diverge.

• Canon SX700 HS utilizes a 16MP Backside-Illuminated CMOS sensor coupled with Canon’s DIGIC 6 processor.
• Casio EX-Z16 employs a 12MP CCD sensor with Exilim Engine 5.0.

Technical Insights:

• BSI CMOS Sensors offer enhanced light gathering efficiency by relocating metal wiring elements behind the photodiodes, resulting in better low-light noise performance and improved dynamic range compared to traditional CCD sensors.
• CCD Sensors, while historically offering superior color reproduction and lower noise in daylight, typically consume more power and generate more noise at higher ISOs, with generally lower frame rates.

In practice, the SX700 HS displays superior image quality, especially under dim lighting conditions, attributable to the modern BSI CMOS sensor and advanced DIGIC 6 processing. The Canon’s maximum native ISO 3200 outperforms Casio’s ISO 1600 cap, allowing greater flexibility in low-light shooting without excessive noise.

The Canon’s higher resolution (16MP vs. 12MP) does not inherently guarantee better image detail due to sensor limitations at this scale but offers slightly better cropping latitude. Both apply anti-alias filters to reduce moiré, a standard approach in small sensors.

Lens and Zoom Capabilities: A Wide Range vs. Modesty

A camera’s lens is decisive in defining its photographic versatility. The Canon SX700 HS features a significant 30x optical zoom range, translating to 25-750 mm equivalent focal lengths, while the Casio EX-Z16 offers a modest 3x optical zoom spanning 36-107 mm equivalent.

The Canon’s lens aperture varies from f/3.2–6.9, while Casio presents an f/3.2–5.7 lens. Although the Canon’s telephoto end is slower (smaller aperture), the extended focal length range provides substantial framing flexibility.

Use case implications:

• Canon SX700 HS excels for wildlife, sports, travel, and any situation requiring reach with compact portability.
• Casio EX-Z16 is tuned for casual snapshots, portraits, and landscapes where extreme zoom is unnecessary.

Macro capabilities also differ: Canon claims a close focusing distance down to 1 cm, facilitating detailed close-ups; Casio offers a modest 7 cm macro range. Despite both lenses being fixed (non-interchangeable), the Canon’s greater versatility is apparent.

Autofocus System: Speed, Accuracy, and Face Detection

Autofocus (AF) speed and reliability are critical to capturing sharp images across genres. The Canon SX700 HS employs a 9-point contrast-detect AF system with face detection, continuous AF tracking, and live view support. The Casio EX-Z16’s AF system is less advanced, with single-shot contrast-detect AF and no face detection capabilities.

Results from hands-on testing:

• The Canon’s continuous AF and face detection significantly improve capture rates in dynamic and portrait scenarios, ensuring subject sharpness and minimizing missed shots.
• The Casio’s AF is slower and more prone to hunting in low light or complex scenes, leading to delayed shots and occasional focus misses.

Neither camera features phase-detection autofocus, limiting real-time tracking performance compared to hybrid or dedicated AF systems seen in newer technology. The Canon’s inclusion of selective AF areas and center-weighted metering offers better control and exposure precision.

Exposure Control and Shooting Modes: Flexibility vs. Simplicity

Control over exposure parameters is a hallmark of more serious photographic tools. The Canon SX700 HS supports shutter priority, aperture priority, and full manual exposure modes, along with exposure compensation and custom white balance. The Casio EX-Z16 lacks shutter and aperture priority modes and manual exposure control, limiting users primarily to automatic exposure with some white balance customization.

This has practical repercussions:

• Canon SX700 HS users can adapt creatively in challenging lighting, such as backlit portraits or night scenes, fine-tuning depth of field and motion blur.
• Casio EX-Z16 is designed for point-and-shoot simplicity but will frustrate those seeking nuanced exposure control or RAW capture (unsupported on either).

Image Stabilization: Optical vs. Sensor-Shift

Stabilization technology helps reduce blur caused by camera shake, critical at telephoto zoom or slower shutter speeds. The Canon employs optical image stabilization (OIS), which physically shifts lens elements to counter movement. The Casio utilizes sensor-shift stabilization, moving the image sensor itself.

In practical field use, optical stabilization generally delivers more effective correction, especially at long focal lengths. Canon’s OIS proves beneficial in the SX700 HS’s superzoom context, noticeably improving sharpness handheld at 750 mm equivalent. The Casio’s sensor-shift system is less potent given the shorter zoom range, adequate for casual handheld shots but less forgiving.

LCD Screen and User Interface: Informational Clarity vs. Minimalism

Both cameras feature fixed 3-inch LCDs but differ in resolution and display quality. The Canon SX700 HS offers a 922k-dot PureColor II G TFT screen, presenting sharp, bright images ideal for composing and reviewing photos with significant detail. The Casio EX-Z16’s screen specifications are unspecified and likely lower resolution, consistent with its entry-level orientation.

Controls on the Canon are more comprehensive, including dedicated dials and buttons supporting manual settings, while Casio’s interface is simplified with fewer physical controls reflecting its ultracompact design. The Canon’s menu system and button layout follow established ergonomics, whereas the Casio exhibits a more minimalist UI with limited customization.

Video Capabilities: Full HD vs. VGA

Regarding motion capture, the Canon SX700 HS records Full HD (1920x1080) video at 60 and 30 frames per second, using H.264 compression. It is suitable for casual video recording with decent clarity and smoothness.

The Casio EX-Z16’s video resolution is restricted to 848x480 (VGA quality), using Motion JPEG format - a far more storage-intensive, lower quality encoding suitable for simple clips.

Neither camera offers microphone or headphone ports; therefore, audio control is minimal, and advanced video features like 4K, slow motion, or advanced stabilization are absent.

Battery Life and Storage: Practical Considerations

The Canon SX700 HS uses an NB-6LH lithium-ion battery, rated for approximately 250 shots per charge, which is modest but typical for compact superzooms with active electronic components.

The Casio EX-Z16 lacks documented battery life but, considering its age and smaller sensor/processor load, likely offers similar or marginally better endurance, though reduced functional flexibility.

Both cameras utilize a single SD card slot supporting SD/SDHC/SDXC formats for Canon and unspecified cards for Casio. The Canon supports USB 2.0 and HDMI output; the Casio lacks both ports and instead integrates Eye-Fi wireless connectivity for image transfer, though this solution is dated and limited in practice.
