Had a quick search, but appears no one has looked at this, so;
With reference to
this page,
this one, and
this one.
I have a k-7 and one of my pet firmware upgrade peeves is that they never upgraded the # of frames in the intervalometer menu from 99 to 999 (as per anything more recent, including the Q, which is rich given that the Q can only shoot about 300 due to battery limitations). No such issues with the K-7. I currently use a cable invervalometer, but that isn't much good in the rain or snow.
I also wonder if it is possible to deactivate the Dark-Frame-Subtraction with this method ( the "DISABLENR" may be of interest).
Has anyone previously tried modifying settings in the debug to modify the number of actuations, or cancel the DFC?
