Canon Powershot A40 Review
The three point AiAF focusing system works from 2.5 ft. to infinity in normal mode and from 6.3 in. to 2.5 ft. in wide angle macro and 10.2 in. to 2.5 ft. in telephoto macro. The conversion Lens Adapter (LA-DC52B) is required for use with the wide angle or telephoto adapter lenses. In addition, the camera's Lens Adapter is needed for the 250D (Canon's 52mm Close up lens) and it will also accept any 52mm filter for special effects.
The Wide Conversion Lens (WC-DC52) when attached to the A30 or A40, has a .7x magnification which creates a wide angle effect equivalent to 24.5mm (35mm format).
The Telephoto Conversion Lens (TC-DC52) when attached to the A30 or A40 has a
magnification factor of 2.4x which creates a telephoto effect equivalent to 252mm (35mm
The real image optical zoom viewfinder is large and bright with central focusing marks.
It shows approximately 85% of the captured image. There is no diopter adjustment. The
two LEDs indicate focus and flash status.
The controls on the back are minimal but effective. When in record mode the SET button selects the flash mode (auto, redeye, on, off, slow-sync), the LEFT button selects the drive mode (single, continuous or selftimer), the RIGHT button selects the focus mode (normal, portrait, macro, landscape). If you're in Manual record the "+/- WB" allows you to set an EV compensation value (+/- 2.0 in 0.3EV steps) or select the desired white balance (auto, sunny, cloudy, incandescent, fluorescent or B&W).
The MENU button calls up the onscreen menu in record or playback (see the next two pages) and you navigate the options with the LEFT or RIGHT buttons and accept selections with the SET button. The DISPLAY button turns the color LCD on/off and also controls the amount of data overlayed on the screen.
The Mode Dial lets you select Play, Auto Record, Program AE Record, Manual Record , Stitch
Assist mode for recording panoramas or Movie Mode.
The zoom control button operates the motorized zoom when in Record mode and also serves
as the Index and Zoom control when the camera is in Playback mode.
The PowerShot A40 Zoom has a CompactFlash Type I card slot and Canon supplies an 8MB card.
There is an ejector button below the card that makes changing the card very easy but
be ready to catch the card if it's pointed downward!
The I/O ports include the DIGITAL port for connection to the host computer's USB port or
to the Canon CP-10 Card Printer. The VIDEO OUT
port lets you connect the camera to a television set for playback, the format is user
selectable for NTSC or PAL. An optional AC adapter can be connected to the DC IN port.
Unlike most of Canon's other compact cameras the A40 is powered by four AA type batteries. A set of alkaline batteries are supplied but I highly recommend the use of high-capacity NiMH rechargeables which are more environmentally friendly.
The internal clock data and camera settings are maintained by a CR2016 lithium battery that is located next to the CF card door.
