Canon PowerShot A5 Camera Twain Driver
Canon was Canon PowerShot A5 Camera Twain of the first digital camera manufacturers to reach beyond the Canon PowerShot A5 Camera Twain resolution category, with their original PowerShot At the time, the PowerShot broke new ground and established a benchmark for sharpness and image quality. Since then, Canon has lain quiet for a long time, leading to much speculation about their long-term plans relative to digital photography. With the release of the PowerShot A5 and the forthcoming PowerShot Pro 70 though, Canon has not only conclusively demonstrated its commitment to digital photography, but returned to the cutting edge of digital camera technology as well.
In the A5, we find a very appealingly packaged K-pixel camera with a commanding set of capabilities including an effective ISO speed reaching as high as Truly a shirt-pocket camera, the A5 provides truly excellent image quality in a very compact package. The 30 total bits captured for the three color channels are reduced to the "best" 24 bits in the finished image files. The A5 includes both an optical viewfinder and back-panel LCD screen for framing, and includes a high-quality glass autofocus lens, built-in Canon PowerShot A5 Camera Twain flash, and useful software.
The rectangular body is entirely constructed from anodized aluminum, conveying a very rugged feel.

Viewfinder In common with many other digital cameras on the market today, the PowerShot A5 addresses the "optical vs. LCD" viewfinder controversy by providing both.
A bright optical viewfinder provides framing marks for the "normal" mode of the camera, and the back-panel LCD screen can be used either as a viewfinder a necessity when operating in "macro" modeor to review images already captured. You can turn the LCD viewfinder on or off at any time by pressing the metal "LCD" button on the back of the camera when in "capture" mode.
Like all such panels, the Canon PowerShot A5 Camera Twain on the A5 is moderately power-hungry, so you'll want to be judicious in its use to conserve battery life. Fortunately, we found the A5's optical viewfinder more than adequate for most picture-taking, and about the only time we really felt a need for the LCD viewer was when doing macro photography.

We found the "bright" mode on the display particularly welcome when working with it outdoors on a bright day: While still no match for direct sunlight, the extra brightness is a real help in seeing what you're focusing on or what you've already captured.
As you might expect though, the added brightness comes at the expense of drastically curtailed battery life.
We didn't do any quantitative tests of this, but would guess that running the display with the brightness turned up cuts battery life at least in half, and possibly more. Optics At the professional end of the 35mm film-camera spectrum, Canon Canon PowerShot A5 Camera Twain renowned for the quality of their optics. While we don't know the details of the A5's lens construction other than a notation in the documentation that it is an all-glass, aspheric designits performance certainly seemed worthy of the Canon heritage.

The macro mode provides for close-ups of small objects, covering an area of roughly 2. For reference, the small brooch in the "macro" test shot is about 1.
This is exceptionally good macro performance for a point and shoot camera, although the slightly wide-angle lens makes for shorter working distances than would a longer focal length. A very welcome feature on the A5 was its built-in illuminator for the passive autofocus system: When shooting in low light levels, the camera projects a bright, striped beam Canon PowerShot A5 Camera Twain an on-board LED onto the subject, just before the shutter fires.
This provides a Canon PowerShot A5 Camera Twain "target" for the autofocus system, even in total darkness.
