• Pentax H90: 101 x 65 x 28 mm; 153 g

The Pentax H90 offers a slimmer footprint and considerably lighter weight, favoring pocketability and discreet street shooting. The Canon SX700 HS, while still pocketable, incorporates a more robust grip area that improves hold stability during high zoom use. Indeed, the 30x zoom of the Canon demands steadier handling than the Pentax’s 5x range.

Control Interfaces and Layout

Control ergonomics affect workflow efficiency. The SX700 HS features a more contemporary control scheme including dedicated exposure modes (manual, aperture priority, shutter priority), a substantial 3-inch screen with higher resolution, and a top-mounted control cluster that includes a mode dial and zoom lever.

Conversely, the Pentax H90 opts for simplicity with fewer dedicated dials and buttons, lacking shutter or aperture priority modes and presenting a smaller 2.7-inch display with significantly less resolution. Its controls are minimalist, which benefits novices but frustrates users used to granular manual control.

The top-down comparison illustrates Canon’s more tactile, user-focused control layout which facilitates quicker adjustments especially under changing lighting or subject conditions. Pentax’s approach simplifies operation but at the expense of configurability in dynamic shooting scenarios.

Screen and Viewfinder

Neither camera incorporates an electronic viewfinder; both rely on rear LCDs for composition and review. The Canon’s 3-inch PureColor II G TFT display offers 922k-dot resolution for sharper image preview, aiding focus assessment and menu navigation. The Pentax’s 2.7-inch LCD with only 230k-dot resolution is noticeably duller and less detailed, impeding fine focus confirmation especially in bright outdoor settings.

The lack of a tiltable or touch-sensitive screen on both models limits compositional flexibility but Canon’s superior display helps mitigate this shortfall.

Sensor Technology and Image Quality: 16MP CMOS vs 12MP CCD

At the heart of every camera lies the sensor and image processor, foundational determinants of image fidelity, dynamic range, and noise handling.
