maybe the a series don't even have a mechanical shutter, but the s does.
If the camera has a flash, it also has a mechanical shutter.

The S and G series have a mechanical central lock.
The M3 has a mechanical focal plane shutter and the first curtain is electronic.

ok, so those shutters are not designed the same way, I would not know what this difference means in the physical world.
but in my opinion, the fact that i can feel it bang against the end does not bode well from a durability point of view.

however, that won't stop me from trying to see how long it takes :)

Not sure if a G support the power down function.


When I saw the posts on the M series power down and restart function I thought that would be a great way to fix the non-working 'Restart' function on recent G series cameras.
Unfortunately I have not been able to find the equivalent code on either the G5X or G7X2. It may be there; but it's hiding pretty well from me :)

That feature requires a camera with "subcpu" (a low-power MCU, separate from the DIGIC). To my knowledge, the EOS M series are the only modern cameras with subcpu.

There are 'SubCPU' related strings in the firmware and some similar functions exist between M & G; but nothing resembling the power down / restart code (that I could find). As you say, most likely the hardware support is not there.

My second attempt with the CHDK script PowDownInt.lua.  The script runs very stable.

Again, with the Canon EOS M3 and the EF-M 15-45mm at 25mm.
Tv = 1 / 30s, F10, ISO100.

The whole thing ran for almost 4 weeks with an interval of 60 minutes. Unfortunately, the peppers stopped growing.

In this case I had a lot of flies. In the first half I tried to reduce this by a median of 3 images. The second half shows the unedited images.

I wanted to know how long the script runs with one battery charge on the M3. The battery is approximately 3 years old. The camera runs about a day and takes 1400 pictures (1 minute interval).

After I had recharged the battery, CHDK no longer ran. Something had happened to the SD card. Perhaps the last write access was canceled. After I reformatted the SD everything is fine again.

Update Script in first post. Add stop on low  battery.

Another try with the M3 and a 5 minute interval. I have a little fewer shots than a minute. This is probably due to the stop when the battery is low .
