The Nikon S800c, unveiled four years earlier, uses a simpler control scheme suited more toward point-and-shoot convenience. Its touchscreen is larger (3.5 inches vs. Canon’s 3 inches) and employs an OLED panel with anti-reflective coating, delivering vibrant colors and excellent outdoor visibility.

However, the Canon’s touchscreen, despite being smaller and employing an earlier LCD tech, offers a responsive experience including touch focusing and menu navigation.

In summary, if you prize compact size combined with precise manual control, the Canon G9 X II offers a more refined ergonomic and operational experience, while the Nikon excels in offering a larger zoom lens and brighter screen at the expense of direct control sophistication.

Sensor and Image Quality: The Heart of the Matter

Arguably the most significant difference between these cameras lies beneath the lens: their sensors.

The Canon G9 X Mark II incorporates a 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm, providing an imaging area of approximately 116.16 mm². This sensor boasts 20 megapixels, delivering a maximum resolution of 5472 x 3648 pixels - a level of detail and dynamic range superior to many compact cameras. Its DIGIC 7 processor enhances noise reduction and color rendering, contributing to excellent results even in challenging lighting.

Meanwhile, the Nikon S800c is built around a smaller 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55 mm, ~28.07 mm²) with 16 megapixels at 4608 x 3456 maximum resolution. The smaller sensor size and fewer pixels inherently confine its capacity to render fine detail and handle noise.

Quantitatively, DXOmark assigns a score of 65 to the Canon G9 X II, highlighting its robust dynamic range (12.5 EV) and color depth (21.9 bits), confirming its potential to outperform many entry-level models. The Nikon S800c has not been recently tested by DXO, but based on sensor specification and era, its low-light ISO and dynamic range lag behind modern standards.

Real-world Implications for Photography Genres

• Portraits: The Canon’s larger sensor and wider maximum aperture (F2.0-4.9 equivalent) enable pleasant background separation and smooth bokeh - critical when rendering natural skin tones and isolating subjects. The Nikon’s smaller sensor and narrower aperture range (F3.2-5.8) produce images with more depth of field, which can be less flattering for subject isolation but forgiving for casual snaps.

• Landscapes: The Canon’s superior dynamic range delivers better preservation of highlights and shadows in high-contrast scenes, making it the favorable choice for landscape photography. The Nikon’s extensive zoom can capture distant vistas, but compromised quality under demanding conditions diminishes appeal.

• Night and Astro: The Canon’s higher native ISO range (up to 12800) and better noise control allow usable images in low-light or night scenarios, including astrophotography. The Nikon maxes out at ISO 3200 and generally requires longer exposures with increased noise.

Autofocus and Speed: Tracking the Moment

Autofocus (AF) proficiency is paramount across all photography disciplines, from sport to wildlife or street candid shots.

Canon G9 X II employs a contrast-detection AF system coupled with touch-to-focus on the LCD. It supports single, continuous, and face detection autofocus modes but lacks phase-detection pixels, which are becoming the industry standard for speed and tracking accuracy. Notably, it offers animal eye AF at zero and includes 0.14-second focusing times under optimal light.

Nikon S800c, despite its older age, features contrast-detection AF with selectable AF areas including 9 focus points but targets mainly center-weighted focusing, also supporting face detection. It lacks manual focus control and touch AF altogether.

In practice, the Canon’s system responds faster and more reliably in good light for tracking moving subjects, aided by higher continuous shooting speeds of 8.2 fps compared to Nikon’s 8.0 fps, although neither excels by today’s high-end standards.

Lens and Zoom Versatility: Fixed-Focal Brilliance vs Superzoom Reach

One defining trade-off between these cameras lies in their fixed lens design.

• The Canon G9 X II has a 28-84mm equivalent (3x zoom) lens with a bright maximum aperture of f/2.0-4.9, ideal for portrait and low-light work, but limited telephoto reach.

• The Nikon S800c sports a long 25-250mm equivalent (10x zoom) with an aperture of f/3.2-5.8, offering tremendous flexibility for travel, wildlife at a distance, or telephoto shots, albeit with reduced light-gathering capacity at longer focal lengths.

Users prioritizing optical versatility for subjects far away will gravitate to the Nikon’s zoom, whereas those focused on image quality and larger sensor benefits favor the Canon despite its shorter zoom.
