Testing the build CHDK_DE_sx700hs-100e-1.5.0-5596 on my SX700 I've found so far the following issues:
Thanks for the reports.
script command set_focus -1 (or any high value near to infinity) does not work, however this issue was discussed on different other topics already.
Different cameras have different limits and issues, so it's not clear if this is a bug or expected behavior.
This camera requires MF or AFL enabled (either with the Canon UI or set_mf or set_aflock) for set_focus to work at all. In those modes, calling set_focus should immediately update the focus distance.
You can use the DOF calculator to show the current SD value, under OSD settings->DOF Calculator
set "Show DOF Calculator" to "in misc"
check "Show Subj. Dist. in Misc."
The port is configured so that 1562414mm is largest non-infinity value that can be set. Values beyond that should result in infinity. However, at the wide end of the zoom, it will go to infinity at much lower values (my sx710, which I think has the same optics, shows infinity with set_focus(10000) at full wide). Setting -1 should set focus to "infinity" but that may actually give you the best infinity focus.
Additionally, set_focus only focus at certain steps. On my sx710 at full wide, setting 4000 to 9000 all result in SD around 5000.
CHDK OSD in video mode: displayed values seem to be sensless: "0001 kbit/s" (sometimes vaues up to "0004") or permanently "00:00:01" if video time remaining should be displayed.
Yeah, these cameras don't seem to update free disk regularly while the video is recording.
Override ISO value via CHDK menu: works fine if values below the minimum value of Canon standard (e.g. 50 ISO) are choosen, however it fails if the Canon standard was set to values between 400 ... 3200 ISO (all PSAM modes).
Do you mean 400 to 3200 in the CHDK override value, or that the Canon UI is set to those values, while a different value is in the override?
In this cases the camera switches of if the shutter is pressed.
As caefix said, a posting a romlog would be good. See
https://chdk.fandom.com/wiki/Debugging#Camera_crash_logs_.28romlog.29Note that values beyond the Canon limits may not crash, but they probably don't actually set the ISO much beyond the Canon limit. That means that ISO override is really only useful for script, or for Canon settings that restrict the ISO (for example, many cameras force low ISO for long exposures)
