Getting to Know the Cameras: Body Design and Handling

Before diving into sensor specs or image quality, camera physicality greatly influences direct experience and shooting comfort. Both cameras are compact, yet their design philosophies and ergonomics differ notably.

The Canon G9 X, with dimensions 98x58x31 mm and weighing 209 g, is marginally thicker and heavier than the sleeker Panasonic SZ5 (104x58x21 mm; 136 g). Canon employs a more robust build featuring a substantial grip, which - supported by its slightly larger physical footprint - contributes to more confident handling during extended shoots or when shooting handheld in low light.

In contrast, the Panasonic SZ5 sacrifices some grip comfort for portability by adopting a thinner, lighter body design devoid of tactile contours. While this facilitates ease-of-carrying and discreet street photography, it inevitably compromises grip security and might challenge users with larger hands or those shooting with heavier wristwatches or bracelets.

Operating controls further differentiate their usability, as revealed by the top view layout.

Canon's top panel integrates straightforward physical dials and buttons, including a dedicated exposure compensation dial and mode dial supporting aperture, shutter priority, and manual exposure modes, enabling nuanced creative control and fast in-field adjustments. Conversely, Panasonic omits such dedicated dials, relying primarily on menu-driven settings with fewer direct physical controls, limiting rapid access and customization - a factor potentially frustrating for users accustomed to tactile feedback or those wishing to fine-tune settings swiftly during dynamic shooting.

Overall, ergonomically, the G9 X asserts itself as a more thoughtfully designed shooter suitable for users wanting balance between compactness and operational comfort, while the SZ5 appeals to those prioritizing ultimate portability over full-control immediacy.

Sensor Size and Image Quality: The Heart of Capture

A fundamental determinant of image quality is sensor size, often dictating dynamic range, noise performance, and depth of field control. Canon’s utilization of a 1-inch backside-illuminated CMOS sensor measuring 13.2x8.8 mm substantially outclasses Panasonic’s 1/2.3-inch CCD sensor at 6.08x4.56 mm in surface area.

The roughly 116 mm² (Canon) vs 28 mm² (Panasonic) sensor size difference (about fourfold in area) endows the G9 X with distinct advantages:

• The larger sensor absorbs significantly more light, crucially enhancing low-light sensitivity and reducing noise at higher ISO values.
• Broader dynamic range captures richer tonal gradations and better preserves shadow and highlight detail during challenging lighting.
• Better color depth and more faithful skin tone reproduction with its 20-megapixel BSI-CMOS array (versus Panasonic’s 14 MP CCD) also contribute to superior image fidelity.

DXO Mark scores bolster this conclusion: Canon’s G9 X posts an overall score of 63, with impressive 21.5 bits color depth and 12.3 EV dynamic range, compared to untested but predictably limited Panasonic CCD performance constrained by sensor size and older technology - classic hallmarks of 1/2.3" sensors historically.

What does this mean practically? The Canon G9 X’s images sport cleaner dark areas, richer colors, and improved shadow recovery, while the Panasonic SZ5’s images more quickly show noise with elevated ISOs (max native ISO 1600) and narrower exposure latitude, constraining creative latitude in mixed or low-light conditions.

Display and Interface: Engaging with Your Images

User interaction with the camera’s display profoundly affects shooting accuracy, image review, and menu navigation. Both cameras offer 3-inch LCD screens, but with distinct characteristics.

The Canon G9 X’s touchscreen display is high resolution at 1040k dots, delivering crisp previews with accurate colors and offering touch-based autofocus selection and menu navigation - a substantial ergonomic advantage when quickly framing subjects or adjusting settings. Meanwhile, Panasonic’s SZ5 sports a lower-resolution 230k-dot non-touch TFT screen, which may hinder composition precision, especially under bright conditions, and limits intuitive control - particularly an impediment for users accustomed to modern touchscreen operation paradigms.

Neither model includes electronic viewfinders, forcing reliance on the rear LCD in all conditions - presenting challenges in bright daylight but fare well in indoor or shaded environments.

Autofocus and Shooting Responsiveness: Speed and Accuracy in Action

Autofocus systems directly impact effectiveness for fast-moving subjects and creative control for precise focusing, especially in portraiture, sports, and wildlife photography.

The Canon G9 X features a contrast-detection autofocus system with touch-to-focus capabilities and advanced face detection, offering AF modes such as continuous (AF-C), single (AF-S), tracking, selective, and multi-area AF, plus center point targeting. Though lacking phase-detection points common in newer cameras, its system remains responsive and reliable for still subjects and moderate movement.

Panasonic’s SZ5 relies on a 23-point AF array using contrast detection without touch AF or face-based enhancements beyond basic face detection. Its continuous shooting rate maxes out at a slower 2 fps compared to Canon’s 6 fps, limiting utility for sports or high-motion scenarios.

Considering autofocus coverage and speed, the Canon G9 X outperforms the SZ5, especially for portrait photography, where eye and face tracking ensure sharp eyes - a critical attribute missing in the Panasonic model.

Zoom Range and Lens Characteristics: Flexibility or Brightness?

The fixed focal length lens on a compact camera defines its framing versatility and creative possibilities.

• Canon G9 X: 28–84 mm equivalent focal range with an aperture range of f/2.0–4.9, covering 3x optical zoom.
• Panasonic SZ5: 25–250 mm equivalent focal length - an impressive 10x optical zoom - but with a slower maximum aperture ranging from f/3.1 at wide to f/5.9 telephoto.

While Panasonic’s extensive zoom range enables effective reach for wildlife or distant subjects, the narrower maximum apertures reduce light gathering ability, particularly at the telephoto end, hampering autofocus and image quality in dim conditions. In contrast, Canon’s brighter lens excels in low light and produces shallower depth of field for aesthetically pleasing bokeh during portraiture.

Neither camera includes lens stabilization beyond optical IS, yet Canon’s stabilizer works effectively paired with the lens and larger sensor advantages to facilitate sharper handheld shots.
