You guys are absolute geniuses. All working now. Brilliant. Now I just need to make my remote shutter release which is easy for me and set the mode on the camera and give it a whirl. Top marks to you all.

The firmware version was (I) eye after all. Anyone else whose wondering canon don't make it easy distinguishing the difference between an l and an I.

If you are going to be using remote shutter a lot,  you might be interested in the features built into the newer development verson of CHDK.  The current stable release is a little hard to understand.   Here's some links :

link>Current USB Remote Shutter wiki page

link>Develoment USB Remote Shutter wiki page

link>Download site for development version of CHDK

Thanks. I have set the camera and the USB cable release works fine. It does require a double push. And I don't seem to have the option of setting up for one push! Still it's a small price to pay for getting some great wildlife shots.

Its possible to set that up in the stable version but the push timing can be tricky.   The dev version of CHDK from the download link I posted is a lot easier to setup and actually works properly.

Thanks. I will give it a go as a single push would be much easier.

You could also take a look at this :

http://chdk.wikia.com/wiki/USB_Remote_Cable#Enable_built-in_CHDK_remote_support

The second line of the chart shows how to setup the Remote Menu to get "one push" with the stable version of CHDK.  The wording of the menu choices does not really explain this but try it and it should work.

Does CHDK allow the use of 'safety zoom' for M1, M2 and S sizes for 16:9 aspect ratio?

The default firmware appears to only allow 'safety zoom' for 4:3 aspect ratio when using M1,  M2 or S size,  but not for any other aspect ratio (unless I'm not setting the camera up correctly).

If not, would this be possible in the future?

Thanks.

I can't get CHDK autoboot working, even though I followed precisely these instructions:


1. Start out with the SD Card Lock switch in the unlocked position (there will be a small slide switch on the side of the card - see picture above - make sure it is in the unlocked position to start this process.)
2. Low level format the card in camera. The card will now contain a single FAT32 partition. (Warning : any images on the card will be erased at this point.).
3. Remove the card from your camera and put it into the SD card reader of your PC. Unpack the appropriate build of CHDK for your camera and firmware version directly to the card (including all subdirectories).
4. With the Card Lock switch still in the unlocked position put the card back into your camera.
5. Turn on your camera by pressing the Play button (or using the Play switch on some cameras). Do not start the camera with the On/Off switch or this process will not work.
6. Start CHDK manually by selecting the Firmware Update option in the Canon menus.
7. After the CHDK logo briefly displays, start CHDK by using the <ALT> key sequence for your camera.
8. Enter the CHDK menu, and select Miscellaneous stuff -> Make Card Bootable
9. Turn your camera off, write protect the SD card by moving the little switch on the side of the card to the locked position), insert the card back into your camera.

My problem is that the camera says that the memory card is locked, even though it should be locked to load CHDK on startup. Does CHDK autoboot support 64 GB memory cards? I can't see why I should be having these problems. I have been using CHDK with the fw update method for some time now, but I find that too tedious, this however is getting on my nerves. I first tried a dual partition method (which is linked to on the main page), and in vain waited some 2.5 hours for the card to format, only for the window to disappear with an error message (something "...too big..."). No mention that this is for cameras older than 2011.

That means the card is not formatted to be "bootable".

It might.

However,  none of us can afford to purchase a card that large so its probably never been tested  8)

All kidding aside,  is it possible that the card is being formatted in the camera as exFAT rather than FAT32 ? You can only boot from a FAT32 formatted card - you will have to format the card in your PC as FAT32 if that's the case rather than in the camera.  However,  while FAT32 will go to 2Tbytes in size,  most PC's will apparently only format up to 32G in size.

So you need to find a 3rd party utility to format the card as FAT32 or setup two partitions and format the card as a 32G card (wasting half the space ... ).
