Neither camera supports touch input; however, both provide intuitive manual menus, customizable function buttons, and essential exposure overrides. The G12 includes minor firmware improvements that streamline navigation, but the overall interface logic remains similar.

Summary: While both cameras offer excellent ergonomics, the G12’s incremental design refinements enhance user comfort and operational fluidity, especially in longer handheld sessions.

Sensor and Image Quality: The Heart of Capture

Both the Canon G11 and G12 employ a 1/1.7-inch CCD sensor measuring 7.44x5.58 mm, delivering effective resolutions of 10 megapixels. The static sensor size and resolution imply comparable pixel pitch and inherent image quality potential; however, extremely subtle optimization in the G12’s signal processing and noise management yield nuanced performance distinctions.

Sensor physical specifications highlight identical dimensions but show minor performance delta due to processing updates.

Dynamic Range and Color Depth

DxOMark ratings confirm near-identical scores in overall imaging quality (47 points each), color depth (20.4 bits), and dynamic range (~11 stops). Practically, there is negligible difference in highlight retention or midtone gradation, supporting detailed landscape and portrait work under controlled exposure.

Low-Light Performance and ISO Handling

Here the G11 and G12 diverge fractionally. The G11 has a slightly higher low-light ISO score (ISO 169 vs. ISO 161), but real-world testing under dim environments reveals both cameras encountering prominence of noise starting beyond ISO 800, with increasingly aggressive noise reduction affecting detail fidelity and texture rendering.

Portrait photographers must rigorously expose to minimize shadow noise, especially given the CCD’s inherent limitations compared to more modern CMOS sensors.

Lens Optics Remain Unchanged

Both models share the same 28-140mm equivalent zoom range with a maximum aperture from f/2.8 to f/4.5, allowing for decent flexibility between wide-angle and short telephoto framing. Macro focusing to 1cm is retained, enabling close-ups with reasonable subject separation.

Summary: Image quality differences are minimal outside of minor noise characteristics; both effectively deliver high-fidelity color, good sharpness, and dependable performance for their sensor class.

Autofocus Systems and Speed: Precision vs. Responsiveness

AF differentiation is one of the more critical operational areas for practical use. Both cameras utilize contrast-detection autofocus systems with 9 selectable focus points and face detection capabilities.

Autofocus Modes and Continuous Performance

The G11 supports continuous AF during live view capture, uniquely allowing focus tracking in video and some photo scenarios; the G12 lacks continuous AF, constrained to single-shot focus lock per frame.

This can complicate shooting fast-moving subjects with the G12, where re-focusing must be manually re-initiated between frames - a critical limitation for wildlife and sports photographers requiring fluid subject tracking.

AF Speed and Accuracy

Testing shows both cameras perform adequately in well-lit and static shooting environments, with reliable center-weighted focusing and accurate face detection. Contrast detection remains inherently slower than phase-detection systems, limiting responsiveness in dynamic scenes.

Neither features animal eye autofocus or advanced tracking algorithms making them less optimal for aggressive wildlife or sports photography.

Burst Shooting and Shutter Performance

Continuous shooting speeds remain modest at 1 fps on both models, limiting their utility in action photography where rapid frame capture is essential to catch decisive moments.

The shutter ranges from 15s long exposure capabilities up to a maximum of 1/4000s. Both allow shutter priority modes essential for creative motion control.

Video Capabilities: Basic Yet Functional

The G12 extends video capturing capabilities beyond the G11 by offering 720p HD recording at 24fps, compared to the G11’s limitation to VGA 480p at 30fps. Both record using H.264 compression without microphone input options and lack headphone outputs, reducing professional video usability.

For casual video work, the articulation and image stabilization help maintain steady footage, but neither camera is suitable as a main video production tool.

Build Quality and Weather Resistance

Neither camera includes weather or environmental sealing, a notable shortcoming for outdoor and professional use where dust, moisture, and shock durability are paramount.

The G12’s chassis has a marginal weight increase indicative of subtle reinforcement, but they remain compact point-and-shoot class devices better protected by external bags or housings when venturing outdoors.

Lens Ecosystem and Accessories

As fixed-lens cameras, compatibility with interchangeable optics is nonexistent, limiting adaptability but ensuring a compact lens profile optimized per model. Canon offers external flash compatibility for both, which enable creative lighting setups unavailable with built-in flash alone. However, the absence of extended flash sync options and slow flash recycle times limit strobe functionality.

Battery Life and Storage

The G12 provides a documented battery life of approximately 370 shots per charge, while the G11’s battery life is unspecified but empirically inferior, necessitating more frequent battery swaps or external power for prolonged sessions.

Both utilize Canon’s NB-7L battery packs and support SD/SDHC cards. The G12 extends compatibility to SDXC cards, an advantage if utilizing large capacity cards for extended shooting.
