Canon A540 Operation

While the Canon A540's user interface may seem slightly cryptic at first, it's actually quite efficient. Most camera functions are controlled externally, and a few of the external control buttons serve multiple functions. When you do need to enter the LCD menu system, navigation is straightforward with only two main pages of options. That said, the majority of external controls do require the LCD display to be active. Regardless, the A540's external controls cut down on the amount of time spent searching menu screens, and I particularly like the "Function" menu which became standard on Canon digital camera models in the 2003 model year. Combined with the instruction manual, the A540's user interface shouldn't take more than an hour to get comfortable with.

Record Mode LCD Display: In Record mode, the A540'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 information, no display at all, and the image only.

Playback Mode LCD Display: In Playback mode, the Canon A540's LCD reports the image series number, resolution and quality setting, file name, and the date and time of image capture. Pressing the Display button once pulls up an enhanced information display, with a histogram for checking the exposure. A third press cancels the information overlay entirely. 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.
