Sensor and Image Quality: Technology, Resolution, and Real-World Performance

Both cameras employ a 1/2.3-inch sensor, a common size for superzoom compacts, but differ markedly in sensor technology and resolution.

• Canon SX40 HS: 12MP backside-illuminated CMOS sensor, measuring 6.17 × 4.55 mm (28.07 mm²)
• Olympus SZ-15: 16MP CCD sensor, same size (1/2.3"), 6.17 × 4.55 mm

The Canon's BSI-CMOS sensor affords better light-gathering efficiency compared to the older CCD in the Olympus, typically resulting in improved high-ISO noise performance and dynamic range. Unfortunately, neither camera has been tested by third-party sensor evaluation platforms (e.g., DxOMark) so insights rely on direct testing and photographic output analysis.

Resolution and Detail

Olympus’s 16MP sensor translates to a maximum image size of 4608 × 3456 pixels, whereas Canon produces 4000 × 3000 files. In practice, the difference in megapixels provides Olympus with some edge for cropping and large print output, but noise and detail rendition quality depends heavily on sensor sensitivity and optics.

Noise and Dynamic Range

In real-world shooting, Canon’s BSI-CMOS sensor yields cleaner images at higher ISOs (1600 and above), with less luminance noise visible. Olympus’s CCD sensor struggles above ISO 800, displaying harsher grain and artifacting. Dynamic range is superior on the Canon, preserving more shadow detail, which benefits landscape and night photography.

Lens and Zoom Capability: Power vs Range and Aperture Trade-offs

Both cameras feature fixed lenses with long zoom ratios but with differing focal range and aperture curves.

Canon’s zoom extends a significant step further into super-telephoto territory, appealing for wildlife, sports, and distant subjects. Olympus stays more conservative, trading zoom length for compactness.

Aperture and Low-Light Considerations

The maximum apertures are comparable, with Canon slightly faster at wide-angle (f/2.7 vs f/2.8), but both lenses progressively close down at telephoto to near f/6, limiting low-light telephoto performance. Neither camera offers aperture ring manipulation; all aperture control is electronic, adjustable within their respective exposure modes.

Macro Capability

• Canon has near 0 cm macro focusing (true close-up capability)
• Olympus macro focus range begins at 5 cm

This makes Canon superior for extreme close-ups and detail macros, a consideration for product photographers or nature close-up work.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus remains a critical component, especially for action, wildlife, and event photography.

Canon’s autofocus operates with contrast detection but supports continuous AF during burst shooting, aiding in tracking moving subjects. Olympus lacks continuous AF, limiting its effectiveness in action scenarios.

Face detection is available on both models, improving portrait framing and focusing accuracy on human subjects. Neither supports animal eye AF or phase detection autofocus, which is expected given sensor class and launch era.

Shooting Performance: Speed, Burst Rates, and Shutter Range

For sports or wildlife enthusiasts requiring rapid capture sequences, continuous shooting performance matters.

• Canon SX40 HS: Up to 10 fps continuous shooting, shutter range from 15 sec to 1/3200 sec
• Olympus SZ-15: Also 10 fps continuous, but shutter maxes at 1/2000 sec, minimum 8 sec

Canon offers a wider shutter speed range covering longer exposures, beneficial for low-light and creative slow shutter effects. Both cameras operate reliably at 10 fps burst, but Canon’s simultaneous autofocus during burst gives it an edge in retaining sharpness on moving subjects.

Viewfinder, LCD, and User Interface: Composition and Workflow

The Canon SX40 HS features an Electronic Viewfinder (EVF), while the Olympus SZ-15 relies solely on the rear LCD. The viewfinder presence and screen quality directly affect composition styles and usability in varied light conditions.

• Canon EVF improves visibility under bright sunlight and reduces glare-related issues experienced on LCD-only cameras.
• Olympus’s 3-inch LCD is higher resolution at 460k dots versus Canon’s 2.7-inch 230k-dot articulated screen, but lack of articulating function inhibits framing from odd angles.

For photographers favoring eye-level framing, Canon’s EVF proves indispensable. Conversely, Olympus’s larger, sharper screen benefits casual handheld operation or video recording where eye-level composition is less critical.

Video Functionality: Available Modes and Quality

Both cameras support Full HD recording, but behavioral differences emerge.

• Canon SX40 HS: 1080p at 24 fps, plus 720p and VGA resolutions, employing MPEG-4/H.264 encoding
• Olympus SZ-15: 1080p at 30 fps, plus 720p and 480p, capturing video as AVI MPEG4 or Motion JPEG

The Olympus provides 30 fps at Full HD, producing smoother motion capture. However, the Canon’s H.264 compression offers superior video quality and better file efficiency. Neither camera supports external microphones or headphone jacks, limiting professional audio recording capability.

Both integrate optical image stabilization, but Canon’s articulation screen provides more shooting flexibility during video capture.
