• Viewfinder and Screen: No viewfinder at all; relies entirely on a 3-inch LCD with 461k dots. The resolution can feel coarse, especially under bright sunlight.
• Buttons: Minimal and compact, which may feel cramped for users with larger hands.

Verdict: If you want dedicated physical controls for direct manual adjustment and a more substantial grip for steady shooting, the Canon G15 is the choice. The Sony H90 prioritizes portability and simplicity, appealing for casual photographers or travelers who value a lighter load.

Imaging Components: Sensors, Image Quality, and Lens

Sensor Technology: CMOS vs CCD and Impact on Quality

The G15 embraces a 1/1.7" CMOS sensor with 12MP resolution, whereas the H90 uses a smaller 1/2.3" CCD sensor but achieves 16MP resolution.

• Size Matters: CMOS sensors like in the G15 typically deliver better low-light performance, faster readout, and higher dynamic range because of their architecture. The larger sensor area (41.52 mm² vs 28.07 mm² in the Sony) also collects more light.
• Resolution Trade-off: The H90 ups its megapixel count to 16MP despite the smaller sensor by increasing pixel density, which can introduce more noise especially in low light.
• Image Quality Insights: In our testing and analysis, the Canon G15 excels in color depth (DxOmark color depth rating ~20 stops) and dynamic range (~11.5 EV), resulting in richer tonal gradations and better highlight/shadow detail retention.
• High ISO Sensitivity: The G15's native ISO sensitivity topping at 12800 with usable image quality at moderate ISO levels outperforms the H90’s ceiling of 3200, making it a better option for low light scenarios.
• Antialiasing Filter: Both have anti-aliasing filters to reduce moiré but can slightly soften fine detail.

Lens Comparison: Fast Brightness vs Zoom Reach

• Sharpness: The G15's premium f/1.8 starting aperture is notably faster, delivering better low-light capabilities and more control over shallow depth of field. This is advantageous for portraits and subject isolation.
• Zoom: The Sony’s superzoom extends to 384 mm equivalent, catering to wildlife and sports enthusiasts who need reach, though at slower apertures limiting low-light performance.
• Macro: The Canon can focus remarkably close (1cm) enabling detailed macro shots. The Sony’s 5 cm minimum distance is less effective for extreme close-ups.

User Interface and Viewing Experience

Both cameras rely heavily on their LCD screens for composition and playback but differ significantly in implementation.

• Canon G15: Features a 3-inch, high-resolution 922k-dot TFT PureColor II G LCD. It delivers vivid colors, excellent viewing angles, and detailed previews.
• Sony H90: Uses a 3-inch ClearPhoto TFT with 461k dots. Less detailed and less viewable in strong sunlight, which might frustrate some users outdoors.

Neither offer touchscreen support or articulated displays, a limitation worth noting for vloggers or users who like flexible framing angles.

Autofocus, Speed, and Performance

Autofocus Systems Demystified

• Canon G15: Utilizes a 9-point contrast-detection AF system with face detection and tracking. Includes continuous AF mode suitable for moving subjects.
• Sony H90: Contrast-detection AF with face detection but no continuous AF, slower autofocus performance, and unknown number of AF points.

In live testing scenarios, the Canon demonstrates faster and more confident autofocus acquisition, especially with moving subjects - an advantage in street and event photography.

Shutter and Burst Modes

While neither camera is designed for high-speed sports photography, Canon’s slightly faster burst mode and shutter speed range provide mild competitive advantage.

Practical Shooting Genres: Who Suits Which?

Let’s explore how these cameras perform in key photography genres.

Portrait Photography

The G15’s brightness and manual controls give you more creative freedom for portraits, capturing smooth skin tones and natural backgrounds separation. Sony’s slower lens and smaller sensor cap bokeh quality, making it less ideal for traditional portraits.

Landscape Photography

The expanded dynamic range and richer colors on G15 translate into superior landscapes. The H90’s longer lens range is less relevant here, and its narrower dynamic range and lower resolution make wide, detailed shots somewhat lacking in nuance.

Wildlife and Sports Photography

The Sony’s 16× zoom and lighter form factor appeal to wildlife aficionados needing reach. However, due to slower autofocus and limited burst shooting, Sony struggles to freeze action. G15’s 5× zoom is modest but paired with faster AF and manual controls, it suits nature and slower action better.

Street Photography

Compactness, silent operation, and quick AF are keys. Sony’s smaller size aids portability, but the G15’s better handling, faster lens, and physical controls enhance creative shooting and low-light performance.

Macro Photography

The G15 shines with a 1cm macro capability and bright lens for detailed close-ups. The H90’s 5cm minimum distance is limiting for macro enthusiasts.

Night and Astro Photography

Canon’s superior high ISO performance (up to 12800) and longer exposure times (15s minimum shutter) facilitate low-light and astro shooting better than Sony (max ISO 3200, 30s min exposure). However, neither has features like bulb mode or intervalometer for time-lapse starscapes.

Video Capabilities: Not Just Still Cameras

The G15’s full HD video and H.264 codec provide better footage quality and editing flexibility. The Sony is limited to 720p with MPEG-4, which is sufficient for casual use but less ideal for serious video content creators.

Battery Life and Storage

• Canon G15: Rated for 350 shots per charge using battery pack NB-10L.
• Sony H90: Rated for 290 shots per charge with NP-BG1.

Both cameras support SD/SDHC/SDXC cards. Sony also supports Memory Stick formats, offering a broader compatibility, though SD cards remain the mainstream storage choice.

Connectivity and Extras

• Canon G15: Features Eye-Fi wireless card compatibility, HDMI output, and USB 2.0. No GPS or Bluetooth.
• Sony H90: Limited connectivity, no wireless options, and lacks HDMI output.

The lack of modern connectivity features is not surprising given their age but worth noting if instant sharing is a priority.
