The Canon PowerShot G11 retains similar styling to the PowerShot G10, but takes an important step in the direction of sanity by reducing the sensor resolution from 14.7 to 10.0 megapixels. This should help the Canon G11 offer improved dynamic range, reduced image noise and better low-light performance.

The G11 also features a 2.8-inch tilt/swivel LCD display in place of the G10′s 3.0-inch fixed panel, raises the flash sync speed to 1/2000 second, and adds high-definition HDMI output connectivity.

The Canon PowerShot S90 takes much of the G11′s feature set, and puts it into a more compact, pocket-friendly package. The Canon S90 uses the same lower-res 10.0 megapixel imager, but drops some of the telephoto reach, instead including a stabilized 28 – 105mm equivalent 3.8x optical zoom. The S90 also replaces the G11′s screen with a larger 3.0-inch fixed position LCD display.

The Canon PowerShot SX20 IS takes the place of the company’s existing SX10 IS model, with which it shares a near-identical body design. The Canon SX20 boosts the SX10′s resolution just slightly from ten to twelve megapixels, which equates to an increase in linear resolution of just under 10%. The PowerShot SX20 also offers slightly increased flash range when the ISO sensitivity is under automatic control, with a maximum reach of 22 feet at wide angle, or 12 feet at telephoto.

The most significant change in the Canon PowerShot SX20IS is the addition of high-definition movie capability. Where the SX10 could only record videos at VGA resolution or below, the PowerShot SX20IS can capture 720p (1280 x 720 pixels) clips. The H.264 MOV compression and stereo microphone from the SX10 is retained in the SX20 IS. To take advantage of the higher movie resolution, the Canon SX20 IS also adds an HDMI video output. In other respects, the Canon PowerShot SX20 is essentially identical to its predecessor, including a 20x optical zoom with stabilization and 28mm wide angle, 2.5-inch LCD display, SD / SDHC storage, and power from four AA batteries with alkaline disposables in the product bundle.
