custom auto iso works somehow..but with limitations. likewise in iso override:
exif data for the test images show iso values lower than 80 or higher than 1600..but the images taken with lower values have identical histogram readings with images taken at iso 80. images with exif/display data showing iso 2500 are in fact less bright than images with iso set at 1600. my conclusion: iso override doesnt seem to work right with the a560.
Please see here discussion about iso limits SD1000 ISO Settings Error

I noticed that there isn't a download for 101a; will there be?
Why? What about it? http://grandag.nm.ru/hdk/autobuild/allbest-a570-101a-49.zip
Thanks

Allbest,

I have another bug report, concerning video mode - on S3IS this time

Option OSD parameters -> Miscellaneous values -> Show in video mode doesn't work as it should in video mode of S3IS (which is started with a dedicated movie button, unlike other cameras where shutter is used). Values (like aperture, ISO) are shown only if I half press the shutter during video recording (to do refocus for example). Image distance is shown in miscellaneous (during video recording) only if MF selected or if I half press the shutter

No problem with this on A620

-----

Also, as I mentioned before, if I switch on A620 in video mode, ISO label is showing 0. But if I change to some of photo modes, it starts working and it's working after that in video mode also

That's because this setting nothing to do with actual video recording. It looks only at the dial mode position.

if I half press the shutter during video recording (to do refocus for example)

my A710 doesn't do that. is this a default feature on the S3 (refocusing when half pressing the shutter)? I would totally like this in my cam...

GrAnd:

I checked behavior of my A620 again and you are right - miscellaneous values (in my case aperture, ISO, subject distance) are shown on LCD whether this option is on or off, but values are not updated during video recording if this option if off (altough camera is varying aperture and iso during video recording, dependion on lighting)

But, on S3IS, these values are not shown during video recording, except on half press of the shutter. It would be fine to have this values shown also during video mode, mostly to check if the focus distance is right


a710is:

Yes, S series is different (I bought second hand S3 several days ago) than A series. You can set autofocus mode to continuous, an camera will be refocusing during video recording, or you can force manual refocus with half press of the shutter during video recording. If you fully press shutter, jpeg is saved and video recording continues further (well - if raw is enabled through CHDK, video recording is also terminated, which was discussed in other thread)

Edit to above post

I found out that on S3, I can get Misc. values during video recording by setting "Show misc values" to "Always" instead "Shoot". Didn't try this before because A620 is showing them in video even if this is set to "Shoot"

But - there's another issue - only aperture value is updated during video recording, while image distance and ISO aren't. Values are update if I half press the shutter during video recording


About AF behaviour on S3, it seems that AF is on all the time during video recording (like on  a camcorder), no matter of AF mode setting in the menu, although you can a sort of force AF with half press of the shutter (according to manual)

Thanks Barney. Will try "Use Zoom Buttons for MF" also (although main problem for me isn't using up/down keys for MF, but finding MF button during video recording, without shaking the camera)

You can see changing of "market" ISO value in this mode. The "Real" value  is constant as well as subject distance (CHDK recalcs it but these values don't change)
