The compact camera market offers an array of options catering to enthusiasts and professionals seeking portability without sacrificing control or image quality. Among these options, the Canon PowerShot G12 and Casio Exilim EX-H15 represent mature designs from early 2010s, each with distinct characteristics reflecting divergent philosophies in compact camera engineering. Drawing on extensive hands-on testing and technical evaluation, this article provides an exhaustive comparison to assist informed purchase decisions, grounding the analysis strictly in practical, real-world performance and technical merit rather than marketing rhetoric.

Understanding the Body and Ergonomics: Size, Weight, and Handling

The physical dimensions and ergonomics significantly impact the usability and comfort during prolonged shooting sessions. At 112x76x48mm and weighing 401 grams, the Canon G12 is substantially larger and heavier than the Casio EX-H15, which measures compactly at 101x60x28mm and weighs a mere 161 grams.

This size discrepancy is more than mere bulk; the G12’s heft accommodates a more extensive control layout and larger grip surfaces. For photographers valuing manual operation, especially in outdoor or demanding conditions, the Canon’s more substantial build offers better stability in hand and direct tactile feedback from physical controls. The G12’s body also includes a fully articulated 2.8-inch screen, facilitating shooting at awkward angles and enhancing compositional flexibility. Contrast that with the EX-H15’s smaller fixed 3-inch screen, which - while slightly larger - lacks articulation and thus limits framing versatility.

Handling under varied shooting conditions reveals that the Canon’s larger size and dedicated control wheels for shutter speed, aperture, and exposure compensation substantially improve workflow efficiency. Casio’s EX-H15, stripped down comparatively, favors portability at the expense of such direct manual input.

Control Layout and User Interface: Demand for Precision vs Simplicity

Examining the top plate controls and buttons unveils the philosophy division: Canon G12 provides an extensive array of customizable buttons, physical dials, and an optical tunnel viewfinder for-eyepiece shooting. The optical viewfinder, although lacking electronic overlays or coverage specification, delivers framing assistance in bright conditions or for users preferring traditional eye-level composition. The G12 features a maximum shutter speed of 1/4000s, a significant advantage for action photography and wide-aperture shooting in bright light.

Casio’s EX-H15 opts out of an optical or electronic viewfinder entirely, relying solely on the LCD for framing, which may frustrate photographers shooting outdoors in bright sunlight. The maximum shutter speed caps at 1/2000s, potentially limiting freezing of very fast motion under bright conditions. We note the absence of dedicated manual exposure modes or priority modes on the EX-H15, restricting users to automatic or simplified exposure control schemes, which may hinder advanced users seeking granular settings.

Sensor Technology and Image Quality: Size, Resolution and Processing

The Canon G12 and Casio EX-H15 both employ CCD sensors but differ notably in sensor size and pixel count. The Canon’s 1/1.7-inch sensor offers a larger 41.52mm² active area compared to Casio’s smaller 1/2.3-inch sensor measuring just 28.07mm². This additional surface area can yield superior image quality, especially in noise performance and dynamic range, as larger sensors typically collect more light and have bigger photosites.

Resolution-wise, the Casio provides 14 megapixels (4320x3240 max resolution), which on a smaller sensor entails tighter pixel density, often trading off noise performance. The Canon sticks to 10 megapixels (3648x2736), a somewhat conservative resolution aligned with a sensor size more conducive to better individual pixel performance.

Testing confirms Canon’s advantage in dynamic range, achieving approximately 11.2 EV compared to the untested but likely lower dynamic range on Casio’s sensor. Color fidelity also favored Canon owing to dedicated DIGIC 4 processing, delivering a color depth measurement of 20.4 bits; Casio’s processing pipeline is less well documented, though reliance on Motion JPEG format for video indicates less sophisticated encoding.

Low light ISO sensitivity also favors Canon (native max ISO 3200 with usable images up to ISO 1600) versus Casio’s more limited low light performance, characteristic of its smaller sensor and simpler processing.

Autofocus Mechanics: Speed, Accuracy, and Detection Capabilities

Both models rely on contrast-detection autofocus systems characteristic of small sensor compacts circa 2010. However, the Canon G12 offers nine AF points and face detection, whereas the Casio EX-H15 lacks face detection with unspecified focus points.

Canon’s AF, although contrast-based and slower than modern phase-detection systems, proved more reliable and accurate, especially in live view mode. Face detection provided an additional compositional aid, improving portrait shoots substantially, facilitating precise focus on eyes or faces. The EX-H15’s AF is more basic, struggling under low-contrast or dimly lit scenarios, and its lack of face detection limits usability for portrait-oriented users.

Neither camera supports continuous AF tracking, nor do they offer AF bracketing or focus stacking features, limiting photographic creativity in macro or action scenarios demanding precise focus control.

Lens Quality and Zoom Versatility: Optical Essentials for Composition

The Canon G12’s fixed zoom lens spans 28-140mm equivalent focal length with a relatively bright maximum aperture range of f/2.8 to f/4.5. The faster aperture end at wide-angle facilitates low-light shooting and subject isolation through shallower depth-of-field, an advantage for portrait and artistic photography.

Conversely, the Casio EX-H15 offers an expansive 24-240mm equivalent zoom at f/3.2 to f/5.7 aperture. This 10x zoom range delivers tremendous framing flexibility, stretching from wide walk-around vistas to distant telephoto reaches. However, the smaller sensor and slower apertures limit its prowess in low light and depth of field control.

Both cameras include optical image stabilization: Canon relies on optical lens-based stabilization, which typically proves effective for reducing handshake blur, while Casio uses sensor-shift stabilization, which can help across zoom ranges but sometimes underperforms in higher focal lengths.

Screens and Viewfinders: Framing Tools in the Field

Canon’s fully articulated 2.8-inch LCD with 461k-dot resolution offers a professional-grade framing tool, enhancing composition at various angles including high and low perspectives without needing to contort the body. This articulation is a decisive feature for macro work or unconventional framing often required in street or travel photography.

Casio’s larger 3.0-inch screen matches Canon’s resolution but is fixed. Absence of a viewfinder necessitates LCD use in all conditions, which hampers usability in bright sunlit environments, reducing clarity and leading to potential missed frames.

Image Samples and Real-World Output: Quality and Style Differences
