iso & focus bracketing

... and a last question ;)

on the a530 port it looks like there is something
wrong with the focus and iso bracketing - if i set
one of them and shoot in continuous mode the
camera hangs with a blank screen and i have to
remove the batteries ... exposure time bracketing
works fine

any hint where i might start to search? looks like
the iso and focus overwrite does not work proerly

one more a lot of thanks in advance - image13

hi,

as i said: exposure time bracketing works, but focus and iso
bracketing not - i think something is most probably wrong
with the iso and focus overwrite ... nobody haveing a pointer
or idea for me on how to debug this? is there anywhere some
deeper documentation available about the code other than
what is written in the wiki?

a lot of thanks in advance and best wishes - image13

Overriding is little bit different form bracketing  ;)

however it's strange your cam go in block...do cam switch off also in iso and focus overriding?

deeper documentation available about the code other than
what is written in the wiki?

I don't think  :( I understand you, I'm porting my a550...but this forum and people in it are very helpful!  :D


mhhh...you can see this hierachy function call (for iso bracketing):

Code: [Select]
shooting_iso_bracketing() -> shooting_set_iso_real(short iso, short is_now) -> shooting_set_sv96(short sv96, short is_now) -> shooting_set_iso_mode(int v)
all in /generic/shooting.c

this is an old trunk, i'm not sure is too equal...sorry!

see also property case in include/platform.h (PROPCASE_ISO_MODE)

...and ISOTable in a530/shooting.c

sorry...if I'm not be helpful  :( ...you have to do much debug

good luck!

 




a530: iso and focus overwrite not working

i just checked: looks like focus and iso overwrite does not
work on the a530 - exposure overwrite and nd-filter switching
works however.

what might be the reason for iso and focus overwrite not
working - i assume some wrong address somewhere?

a lot of thanks in advance and best wishes - image13
