Miscellaneous Info - Canon CHDK Quick Start Manual

Q. What's the future for CHDK ?
A. There's no doubt that clever people will continue to develop more features, scripts, etc., and more
cameras will be ported, CHDK will be refined, until it is released as v1.0, and perhaps beyond, which
seems to be very close, so the future looks good for CHDK. This User Guide has been written up to
May 2010. For further firmware revisions refer to the changelog.

Miscellaneous info.

CHDK supported cameras might not always perform as a menu entry might imply, because you can
enter a parameter does not mean the camera can necessarily perform the task, the cameras have hardware
limits that restrict them. (some have less than others)
Extra long exposure capability is not yet available on all CHDK cameras, the cameras listed below are
supported at this time. (May 2010)
A30, A540, A550, A560, A570, A590, A630, A710, G9
IXUS70/SD1000, IXUS80/SD1100, IXUS870/SD880, IXUS90/SD790, IXUS950/SD850,
IXUS970/SD890, S3, S5, SX1, SX10, SX200.
Extra long exposure means these cameras are capable of exposure times of up to 2000 seconds, handy
for Astrophotography and other specialized applications.
CHDK Cameras without standard manual focus, can take advantage of the CHDK focus override,
All of the IXUS series (except IXUS980/SD990), and these others at this time - (May 2010) - A450,
A460, A470, A480, A550, A560, A2000, TX1.
Cameras without an actual aperture/iris mechanism use the ND (neutral density) filter to achieve an
exposure method similar to an actual aperture. CHDK provides control of the ND filter for users to
make their own shutter speed adjustments. The CHDK supported cameras listed below have an ND filter
only, and no actual aperture/iris mechanism.
A450, A460, A470, A480, A530, A550, A560, A2000, TX1.
Some high end Powershot cameras, such as the G series, have both an aperture and an ND filter.
Commonly seen when checking the camera version with the VERS.REQ method, is the E18 error,
this means sometime during the camera's life it has encountered a possible malfunction of the lens
assembly, if the camera is working ok there is no concern.
