In-Depth Comparison: Canon PowerShot G11 vs Canon PowerShot G15 – Which Compact Best Fits Your Needs?

When evaluating compact cameras targeted at enthusiasts, the Canon PowerShot G series has consistently offered a compelling balance between portability, manual control, and image quality. In this detailed comparison, we dissect the Canon G11 (announced late 2009) and the Canon G15 (introduced in 2012) - two successive iterations in this lineup. Both represent strong contenders for discerning photographers preferring a small sensor compact system without interchangeable lenses. By leveraging over fifteen years of rigorous camera testing experience, we examine their technical attributes, real-world performance, and usability across diverse photographic disciplines.

First Impressions and Ergonomics: Designed for Different Eras but Similar Intentions

At a glance, the Canon G11 and G15 embody the classic compact form factor typical of enthusiast fixed-lens cameras, with dimensions under 115mm wide and weights around 350-375g, which facilitates true pocketability compared to DSLR or mirrorless systems.

• Canon G11: Measuring 112x76x48mm and weighing 375g, it retains a relatively chunky profile owing to the inclusion of a fully articulated 2.8-inch LCD. This design decision favored versatility in shooting angles, advantageous for macro and video work but introduced some bulk.
• Canon G15: Slightly more streamlined at 107x76x40mm and 352g, the fixed 3.0-inch LCD panel features improved resolution and visual fidelity, although at the cost of articulation freedom.

The ergonomic enhancements through successive generation, such as refined control dials and button layouts, are made evident in the top-view comparison.

Both cameras share a robust metal chassis with tactile dials and buttons, reflecting Canon’s focus on creating enduring tools for photographers requiring manual control. The G15’s digitized Digic 5 processor allowed marginal improvements in responsiveness and menu navigation fluidity relative to the G11’s Digic 4.

Sensor and Image Quality: Small Sensor, Big Differences in Processing and ISO Performance

Despite identical sensor sizes - both employing a 1/1.7-inch sensor measuring approximately 7.44 x 5.58 mm (sensor area ~41.5 mm²) - critical distinctions arise in sensor technology and image processing.

• Canon G11: Utilizes a 10MP CCD sensor, which delivers characteristic Canon color science noted for pleasant skin tones and natural hues. CCDs traditionally excel in color depth and dynamic range at base ISO but lag in high-ISO noise performance.

• Canon G15: Upgrades to a 12MP CMOS sensor, yielding finer resolution at 4000x3000 pixels and vastly improved high ISO capabilities, maxing at ISO 12800 versus the G11’s ISO 3200 ceiling. CMOS sensors benefit from lower power consumption and enable faster readout speeds, thereby enhancing continuous shooting rates and video functionality.

DxOMark Scores Validate Technological Advances:

• G15 Overall: 46

The numerical closeness belies subtle areas of differentiation:

• Color Depth: G11 at 20.4 bits slightly edges out G15’s 19.9 bits, attributable to CCD lineage.
• Dynamic Range: G15 leads with 11.5 EV compared to G11's 11.1 EV, reflecting more nuanced highlight and shadow retention.
• Low-Light ISO: CMOS advantages give G15 better noise control (ISO 165 vs. 169 score).

In practical terms, both cameras deliver excellent daylight image quality with slight advantage to the G15 in low light and high ISO performance, expanding creative shooting possibilities in dim environments or fast action.

Lens and Optical Performance: The 28-140mm Zoom Remains, But Aperture Widens on G15

Both models are equipped with a fixed 5x zoom lens covering a classic 28-140mm equivalent focal range ideal for general-purpose use.

• G11: Offers a maximum aperture of f/2.8-4.5, which is effective for moderate depth of field control and reasonable low-light shooting at wide angle, but slows down toward telephoto.
• G15: Substantially improves aperture to f/1.8-2.8, translating to brighter images, tighter subject isolation, and smoother bokeh, especially critical in portrait, macro, and low-light scenarios.

Both lenses support macro focusing down to 1 cm, beneficial for close-up photography, though the G15’s faster optics render it more versatile for detailed texture capture with natural background blur. Optical image stabilization is present in both, leveraging Canon’s proven lens-shift mechanisms to counteract handheld shake.

Autofocus Systems: Progression From Basic to Adaptive AF Modes

Autofocus is a key differentiator considering these cameras' potential use for dynamic subjects:

• G11 AF System:

  • 9 focus points with contrast detection.
  • Face detection autofocus available.
  • Lacks advanced tracking or continuous AF sophistication.
  • Continuous shooting at a slow 1 fps limits action photography.

• G15 AF System:

  • Also 9 contrast-detect points but enhanced with AF tracking and selective AF.
  • Improved face detection accuracy.
  • Moves to continuous shoot at 2 fps, enabling better capture of fleeting moments.

Contrast detection AF still falls short of robust phase detection in DSLR/mirrorless systems but the G15’s improvements make it more reliable for moderately fast-moving subjects such as street photography or casual wildlife.

User Interface and Display: Articulated Versatility Meets High-Resolution Fixed Screen

The switch in LCD design deserves focused attention since it substantially affects the shooting experience:

• G11: The 2.8-inch fully articulating screen allows shooting from creative angles and macro framing without contortions, an asset for vloggers and macro enthusiasts.
• G15: The larger 3.0-inch fixed TFT PureColor II G LCD with nearly double the resolution (922k dots vs. G11’s 461k) offers more detailed image review and menu navigation but at the cost of articulation limits.

Canon’s interface remains consistent with physical dials and a responsive control ring on the lens barrel, providing fine control over settings such as aperture and shutter speed. Illumination in buttons is absent on both models, slightly hindering low-light usability. The lack of touchscreens is a given given their launch eras.

Video Capabilities: From VGA to Full HD Evolution

In increasingly multimedia-focused workflows, video functionality cannot be overlooked:

• G11: Restrained to VGA 640x480 @ 30fps, limiting utility beyond casual, low-res clips.
• G15: Advances significantly to full HD 1080p at 24fps, including 720p and VGA options, packaged in the ubiquitous H.264 format. This marks a notable step up for hybrid shooters requiring quality video from a pocketable camera.

Neither camera offers microphone or headphone ports, limiting external audio control - a common limitation in compact cameras of this era. Video stabilization is optical only, dependent on lens OIS.

Battery, Storage, and Connectivity: Pragmatic but Basic

Storage compatibility remains largely unchanged - both support SD/SDHC cards with the G15 adding SDXC support for larger capacity cards.

Battery life is more quantifiable on the G15 (approx. 350 shots per charge with the NB-10L battery) versus the less documented G11 (NB-7L battery). The G15’s CMOS sensor and improved processor confer more efficient energy management.

Connectivity is modest on both: USB 2.0 and HDMI outputs facilitate tethering and playback on external monitors. The G15 adds support for Eye-Fi wireless cards, enabling rudimentary Wi-Fi transfer - a feature absent on the G11, reflecting technological progression over the three-year intervening period.

Neither provides Bluetooth, NFC, or GPS, positioning these as fundamentally traditional cameras without fully integrated modern connectivity.
