    "you'll see the real mechanic structure"
    Yeah, saw it! Thanks. But the diagnosis means that the "ND-filter" item in the "Extra photo operations" menu is an atavism and will not work correctly. As I described above, it works only in non-script mode, and the result is not reflected in EXIF. So it gives the doubtful result. Setting ND-filter IN/OUT gives maybe 1 step, maybe more. Now I have a courage to try "set_av", at least.

    The next issue is a set of props, I found here the most fresh "New Digic IV". Doubtful that it's fully convenient to our camera (as well as all previous sets). Now I'm trying to set/determine the shooting process, and any of props 200 - 210 don't return anything except zeros. The #208 seems to give a 1 after a shot is made, but it's marked as "Flash Ready status" in the previous "Digic III & Digic IV" propset.

    Seems that branch is abandoned by developers, so we have to maintain it ;) Our beta seems to be far from end :(

    CHDK is an all volunteer affair - there are no "developers" who maintain things.  Code for a camera is either maintained by someone who owns the camera or it becomes abandoned.  From that point of view - you are now a "developer".   Welcome onboard !

    "you are now a "developer""

    I had to guess it before :( So now I must tesst not only 10 props, but all of them.
    NB: prop 208 becomes 1 when half_shoot is pressd, prop 210 - only when flash is activated. What to do with this knowledege?

    As far as I can tell - as indicated by the IXUS 200/SD980 the diaphragm has ten steps giving the following apertures:

    f 2.8, 3.2, 3.5, 4.0, 4.5, 5.0, 5.6, 6.3, 7.1, 8.0

    Yeah, great!
    But this doesn't help to manipulate it from the CHDK menu or script. Any attempts seems to be inefficient. I tried all: set_av, set_av_96 etc, as well as props from Digic III and IV and of course, "ND-filter" from "Extended photo operations" :(
    I didn't test totally my A530 (because it has Manual mode)? but remember that its ND-filter was also similarly stubborn. I may be wrong, but this aperture/NDfilter issue may be just declared, but not resolved in CHDK. To test some other cameras can be useful to understand.

    @lalex
    I've enabled the iris (CAM_HAS_IRIS_DIAPHRAGM) in this build:
    CHDK-ixus200_sd980-101c-1.0.0.zip - 0.20MB
    Let us know whether it works.

    @srsa_4c


    I have tested the iris with the given build, all the values in CHDK work upto 8.56, and every chdk value that works gives a different aperture/iris size.

    Tested in fairly dark conditions with a 4second exposure, ISO 80, lens fully zoomed out.

    chdk values = camera/exif values
    2.87 = 2.8
    3.01 = 3.2
    3.18 = 3.2
    3.38 = 3.5
    3.64 = 3.5
    3.98 = 4.0
    4.44 = 4.5
    4.80 = 5.0
    5.05 = 5.0
    5.49 = 5.6
    5.37 = 5.6 (in wrong position should be between 5.05/5.49)
    6.05 = 6.3
    6.80 = 7.1
    7.63 = 8.0
    8.56 = 8.0

    9.61, 10.79, 12.11 all give the same iris size as 8.56

    thanks

    Don't worry about that. The change got into the official CHDK, just download a current autobuild version.

    Downloaded 1791b, it works, GREAT! I can now make auto-panoramas!!!
    Repeated the test of Hamfent in the low daylight (in the room), with 1/60 shutter speed. The same results with non-significant difference:

    chdk values - camera - exif values
    2.87 - 2.8 - 2.8
    3.01 - 3.2 - 3.19
    3.18 - 3.2 - 3.19
    3.38 - 3.5 - 3.51
    3.64 - 3.5 - 3.51
    3.98 - 4.0 - 4.00
    4.44 - 4.5 - 4.51
    4.80 - 5.0 - 5.02
    5.05 - 5.0 - 5.02
    5.49 - 5.6 - 5.60
    5.37 - 5.6 - 5.60 (still in wrong position)
    6.05 - 6.3 - 6.30
    6.80 - 7.1 - 7.10
    7.63 - 8.0 - 8.00
    8.56 - 8.0 - 8.00

    9.61, 10.79, 12.11 all give the same as 8.56. Zoom, ISO and shutter speed doesn't change this in any way.
