Can someone please check whether the set_zoom() script command crashes the camera?

Revision 5144, lua set_zoom(1) - crashes in movie mode only.

@srsa_4c
If you will commit changes, please modify CAM_DATE_FOLDER_NAMING to 0x80.

Committed the fixes in r5148.
Apparently, Canon doesn't plan to release a lens with built-in zoom motor.

There is only one device.

Yeah, I remembered that. But I wasn't aware that it can be controlled by camera

Remote control function is available using smartphones and computers when used with an EOS 80D camera and Canon Camera Connect software.
But that's only one camera and one lens, like it wasn't meant seriously.

Agree.
At the same time we can try to implement focus related functions.
But AFAIK the problem is that focus pulse counter becomes 0 after auto focusing.

The bigger problem is that we'd need something that works with subject distance. I haven't yet tried to go after that lens info function and the source of those subject distance values in the quoted post.

On EOS M3 these values can be taken directly from the lens using EFLensCom.DistanceInfo (0xFC43DF5E), or from structure in RAM at address 0x00244918.
The second way IMHO is better becuse it does not waste Camera<>Lense traffic.

Do you happen to know where those values are populated? 0x244918 is inside a huge structure and is not referenced directly (the firmware's addressing is very hard to follow, lots of base + offset variations).
Even with this, we only have read only access to distance data - still no way to adapt to the current CHDK interface.

Hi there
Can anyone confirm that GRIDS works with the current build for the M3? Particularly in conjunction with an evf? This is the only feature I'm really interested in and am considering buying the camera for this reason. I have an M with ML but I would really like to use an EVF with a custom crop overlay
thanks
