| - | While the Powershoot A590 is one of the only cheap point and shoot cannon cameras to offer manual focus as a standard feature, many other cannon cameras can be given the feature thanks to the good people building [[http://chdk.wikia.com/wiki/CHDK|CHDK]]. CHDK is a free software firmware add-on that you can run from your SD card without having to replace the factory firmware. Depending on what model of canon you have, CHDK adds a number of features from manual focus to raw picture support, a related project [[http://stereo.jpn.org/eng/sdm/index.htm|StereoData Maker]] also adds the ability to trigger the shutter using a USB remote. If you use CHDK for your book ripper, please let us know, we'd love to hear about it. | + | While the Powershoot A590 is one of the only cheap point and shoot cannon cameras to offer manual focus as a standard feature, many other cannon cameras can be given the feature thanks to the good people building [[http://chdk.wikia.com/wiki/CHDK|CHDK]].

| I can confirm that manual focus works with the Powershhot A470 using CHDK. The instructions in their materials could be clearer though. In the CHDK menu you need to turn the first option "Disable Overrides" to "On". That will let you set the "Override Subj. Dist. V" and the "Value Factor" option under it. I left the Subj. Dist. V alone and just set the "Value Factor" to 10mm, this is the increment that you will then be able to control the focus in. Once that is all set up, simply change to the PhotoM option on the camera shooting dial and the left and right control cross/d-pad buttons should zoom in and out. | I can confirm that manual focus works with the Powershhot A470 using CHDK.

| + | The A470 (and other Canons too) can be set to automatically load the CHDK firmware when you turn the camera on. We're looking into custom CHDK builds that will handle focus and white balance and such. | ||
