  • Page 6 With this background in mind, we decided to introduce a new top-of-the-line model, the PowerShot A300, with approx. 3.2-mega camera effective pixels. The PowerShot A300 offers even better image quality, enhanced movie features and improved operability while maintaining the same fundamental design concept of the 2-megapixel PowerShot A200 and the 1.2-megapixel PowerShot A100.

  • Page 9 1-3 Design Concept -The PowerShot A300 design concept: Slim, clean, simple, easy and high quality - Although the basic design is similar to that of the PowerShot A200/A100, the layout of the but- tons, functional markings and operability of each component have been fine-tuned to make this an entry-class digital camera that anyone can use easily.

  • Page 12 -High resolution single-focus 5mm f/3.6 lens (35mm film equivalent : 33mm) The PowerShot A300 is equipped with the 5 mm, f/2.8 single-focal- length lens used on the PowerShot A200/A100. The lens consists of 5 elements in 5 groups including one aspherical (single-sided) lens.
  • Page 13 -High-precision white balance (Auto + Five preset positions + Custom) The PowerShot A300 adds custom white balance to the white balance functions (auto and five-position preset) . The custom white balance allows the user to record a desired white reference (usually a white piece of paper) beforehand under the shooting conditions (light sources) employing a camcorder or other device.
  • Page 14 -Digital zoom function with continuously changing angle of view (Approx. 5.1x) The digital zoom magnification of PowerShot A300 enlarges to approx. 5.1x owing to employment of 3M-pixel CCD. It can adjust the field of view from 33mm to 168mm (35 mm film equivalent) Furthermore, several dozen image input positions are calibrated for the monitor display to ensure a smooth digital zoom of the image on the monitor display.
  • Page 15 - Three types of metering function (evaluative metering, center-weighted average metering and spot metering) With the PowerShot A300, the metering modes of center-weighted average and spot are added to PowerShot A200/A100’s evaluative. The center-weighted average metering measures light over the entire image and weights the sensitivity according to proximity to the center of the image;...
  • Page 16 -Sound memos of up to 60 seconds can be appended during replay When replaying images on the PowerShot A300, because a sound recording of up to 60 seconds can be appended to images, you can easily attach comments to images as desired after shooting. The record- ing format is WAVE (monaural).
  • Page 17 -Three types of recording pixels (VGA/QVGA/QQVGA) for movie mode (VGA is high image quality ) The PowerShot A300 can record movie clips with audio at a rate of 15 frames per second in one of three recording pixels, VGA, QVGA or QQVGA.
  • Page 18 -Unwanted scenes can be deleted in movie replay mode (image and audio) The PowerShot A300 allows unwanted sections to be deleted in the movie replay mode. However, the sections that can be deleted are either from the start of the movie recording to an arbitrary point or from an arbitrary point to the end of the movie recording.
  • Page 19 -Slide type lens cover suggests easy operation The PowerShot A300 has moved from the PowerShot A200/A100 lens cover, which operates with a one-click (rotational) method to open and close, to a sliding style of cover. The sliding cover makes it easy to see how to open and close the cover as well as making it possible to check if the cover is open or closed at a glance.
  • Page 20 DISP. FUNC. MENU The PowerShot A300 operation is straightforward and comfortable due to the use of a cross button. Also, by changing from the rubber switch buttons on the Power- Shot A200/A100 to tact switch type buttons*, a subdued yet classy feel is given to the camera.
  • Page 21: Slide Type Lens Cover Creates High Grade Exterior
