While agonising about converting my 40D pre-order into a firm order I continue to search the Net for new information and I have discovered a feature which is most appropriately shared on this forum.
As you may know, the 40D has a Live View mode and a facility to use this mode while connected to a notebook computer via a USB cable so that the Live View image can be seen in virtually real time on a big screen.
Here are some of the features provided by the program you run on the notebook:
- Live View as described above
- Facilities for moving the spot metering point around the screen
- Use of coarse, medium and fine control buttons for adjusting the lens focus manually
- Set Bulb times greater than 30 seconds
- An "intervalometer" to allow exposures to be taken every so often
Some of these features have obvious application to astrophotography. However, with imagination and suitable power supplies it is definitely not
the case that "the sky's the limit".
Disclaimer: I haven't tested these claims personally and until Canon gets its act together and publishes the appropriate manuals online I can't check them out either.
