Canon A640 Operation
Canon A640 Operation
While the Canon A640's user interface may seem a little strange at first approach, it's easy to master. Things you set once (like sounds or instant review) are accessed by pressing the Menu button in the lower right corner. Settings that might change for a particular outing (like image size, ISO settings, etc.) are accessed by pressing the Function button in the center of the navigator. Options you might change from shot to shot have their own buttons, like EV, Flash mode, Macro mode. The left and right arrow buttons are reserved for changing the value of a setting. There's a Mode switch to toggle Record and Playback and a Mode dial to select among Record modes. It's very efficient, once you learn your way around. Give yourself an hour to do that and you'll be fine without the manual.
Record Mode LCD Display: In Record mode, the Canon A640's LCD reports various exposure settings, including camera modes, the resolution and quality settings, number of available images, etc. Half-pressing the Shutter button reports the aperture and shutter speed settings, in all modes except Manual. (Aperture and shutter speed are displayed continuously in Manual mode, whether the Shutter button is pressed or not.) Pressing the Display button cycles through the available display modes, including the image with no information, the image with information, and no display at all. Through the settings menu, you can enable a gridline or 3:2 aspect ratio display guide.
Playback Mode LCD Display: In Playback mode, the LCD reports the image sequence number on the card, resolution and quality setting, file name, and the date and time of image capture. Pressing the Display button once calls up an enhanced information display, with a histogram for checking the exposure. A third press cancels the information overlay entirely. The Canon A640 remembers your preference, too. The telephoto side of the zoom toggle lets you zoom in on a portion of the image, while the wide-angle side backs you out again, and lets you step out to an index view of captured images, displayed as nine thumbnails at a time. Zooming out one step past the point at which the index display appears adds a jump bar to the bottom of the screen, letting you jump forward or back nine images at a time, rather than scrolling from each image to the next individually. (You can control the behavior of Jump mode by pressing the Jump button, or up arrow, and adjusting the settings.)
Canon A640 Modes and Menus
Record Mode: Pressing the Canon A640's Menu button in Record mode pulls up the following options (not all options are available in all modes):
- AF Frame: Selects three different auto focus modes. AiAF selects the focal point from one of nine focus areas arrayed in the display. Center focuses on a small area in the center of the image. FlexiZone lets you manually select to one of nine points of focus within the viewing frame.
- Digital Zoom: Controls the digital zoom, options are Standard (4x), 1.4x, 2.3x, or Off.
- Flash Sync: Selects whether the flash fires when the shutter opens (1st-curtain) or just before the shutter closes (2nd-curtain).
- Slow Synchro: When switched on, lets you use a slow shutter speed with the flash.
- Flash Adjust: Puts the flash under Automatic or Manual control, meaning that the Auto setting will automatically control flash power based on the exposure conditions.
- Red-Eye Reduction: Turns the Red-Eye Reduction pre-flash on or off, which works with all flash modes.
- Spot AE Point: Sets whether the exposure is measured either at the center of the image, or at the same point as the auto-focus focal point (AF Frame menu item above must be set to Center or Flexi-zone to access this option).
Safety Shift: If enabled, the camera will automatically
correct the exposure in Aperture Priority or Shutter Priority exposure modes,
if the value you've selected will result in a poor exposure.
- MF-Point Zoom: Turns the MF Point zoom option on or off. If on, the center of the frame is enlarged on the LCD display for better viewing while adjusting the manual focus.
- AF Assist Beam: Turns the AF Assist light on or off. If on, the light automatically illuminates in dark shooting conditions.
