I've convinced myself that setting ISO values via Lua 'may' be broken.
I can use camera.iso.apex or camera.iso.value etc to read, eg x = camera.iso.apex; but if I use something like camera.iso.apex = 10 I get 'failed stack traceback' error.
Has anyone else come across this?
Last time I've checked, it used to work:
https://foss.heptapod.net/magic-lantern/magic-lantern/-/blob/branch/lua_fix/scripts/api_test.lua#L785
local apex = math.random(5*100,10*100)/100
camera.iso.apex = apex

@a1ex
Using latest Lua fix on 5D3 123.
Shutter and aperture all OK.
Reading ISO is OK.
Just tried running the API test script and got error "Not enough memory" ???????
Looks like one of my scripts is creating the problem :-(
If I only run API test all looks OK :-(
But which script I wonder?
Time to test!!!!
@a1ex
API test fails here:
Testing picture taking functions...
Snap simulation test...
Single picture...

Well I'm mystified, but that's easy :-)
Here is the point of failure, that generates the traceback error:
local iso_b = camera.iso.apex
local temp = camera.shutter.ms
local stop = MUSIC_menu.submenu["Number of images?"].value
if MUSIC_menu.submenu["Bookends?"].value == "yes" then stop = stop + 2 end
for i = 1,stop do
if (i == 1 or i == stop) and MUSIC_menu.submenu["Bookends?"].value == "yes" then -- tweak shutter and ISO for first and last images in bracket set
camera.shutter.ms = 1
camera.iso.apex = 10 --FAILS HERE!!!!!!!!
else
camera.iso.apex = iso_b
camera.shutter.ms = temp
end
my_shoot()
msleep(MUSIC_menu.submenu["I2I Delay"].value * 1000)
if MUSIC_menu.submenu["Focus shift mode"].value ~= "None" then
check_lens_ready() -- just in case
lens.focus(dir,step,true) -- move lens
check_lens_ready() -- just in case
lens.focus(-dir,step,true) -- move back
end
end
camera.shutter.ms = temp
camera.iso.apex = iso_b
display.notify_box("Script Finished Running", 3000)
else -- something is wrong
display.notify_box("Switch on LV", 3000)
end
In the end I 'just' did a complete reinstall of the latest Lua_fix and all now seems OK.
As I say, strange.
@a1ex
I'm still nowhere with this ISO strangeness.
I have the latest Lua running on my 5D3 in M mode.
I have deleted all scripts bar this test script:
--ISO Test
t = camera.iso.value
menu.close()
sleep(1)
camera.iso.value = 800
display.notify_box("iso="..t, 3000)
sleep(3)
camera.iso.value = t
The script fails with this message:

Can you see the error of my ways?

Bugger: why doesn't the image show!!!!!!
Here is the link: https://ibb.co/G7FXWbF
Fixed :)
@a1ex
I had a thought and just tested it out and now can trigger the error.
If only ExpSim is enabled all is OK.
If I also enable Expo Override, then the error occurs, ie I can't control ISO via Lua.
I don't under why this is occurring, but at least I can circumvent it by not playing around with ISO if I also need Expo Override!
Confirmed - that's a valid bug report.
@a1ex
Thanks for confirming. For a while I thought I was going mad, then, last night, as I was in bed thinking about it, I wondered if the exposim or expo override was the issue.
May I assume the bug is registered now?
Cheers
