Canon PowerShot S90
Introduction The '''Canon PowerShot S90''' is a high-end 10.0-megapixel compact digital camera originally announced in 2009.The PowerShot S90 is the successor of the Canon PowerShot S80.The almost 4-year gap between the S80 and the S90, compared with intervals of 6 months to 1 year between prior versions, led to the line being popularly considered discontinued, and thus the S90 as a revival, rather than a strict successor.

Reception The S90 has received good, in some cases excellent reviews, with reviewers praising its image quality, small size, and ease of using manual mode, particularly due to its distinctive control ring. The fast (f/2) lens and the decision to reduce the pixel count (hence reducing noise; also found in the G11) are particularly cited. The primary criticisms, beyond the general limitations of small sensor and small size, are that its ergonomics are lacking, and in particular that the rear dial moves too easily, changing exposure and often ruining photos.To address the ergonomic criticisms, third parties have developed a custom grip to make the camera easier to grip, and a plastic ring to surround the control dial, making the dial less likely to be accidentally moved.
Similar cameras In the high-end compact camera market, its main competitor is the Panasonic Lumix DMC-LX3 (and the Lumix's sister camera, the Leica D-Lux 4); one significant difference being that the S90 is significantly slimmer due to the fully collapsible lens, hence more portable.The Canon PowerShot S95 was announced and released in 2010.It was designed as the successor to the Canon PowerShot S90.The Canon PowerShot G series (, the G11) are similar in terms of target market, but feature a larger body and slower optics at the wide angle end.PowerShot S90 Rear view.A similar category to high-end compact cameras are mirrorless interchangeable lens cameras ("micros"), some of which are in a compact form factor (with a similar-sized body), such as the Panasonic Lumix DMC-GF1, Olympus PEN E-P1/E-P2, and Sony Alpha NEX-3.Micros differ however in being significantly larger (with lens attached), and significantly higher-end, featuring much larger sensors and interchangeable lenses.
