ok,
thanks everyone for your kind replies, especially a couple of good advices on how to upgrade the firmware without a fear of losing the old one.
however, my problem is that i have the original v1.0 firmware in the camera! where can i find that one for a rollback in the future if and when needed?
and for the RAW+JPG thing, alright, i blame it on my own bad post as i can see that barely anyone here responded well enough to that!
i'm gonna put it in here again but hopefully in a more meaningful phrasing:
on a Pentax K-5, as well as on Pentax K-x and K-r, you can take both formats, RAW and JPG at the same time,
all the time, if you want to, but on Pentax K-7, the story is different, totally and badly different:
on K-7, you can do that
only when you press the RAW button on the camera body's front, to the left of the lens but you can never set the camera in a way that it does it forever, ie, just like the K-5 and those other guys: for as long as you want the camera to do that for you, until, for example, you set the camera differently again and want it to take only one of two formats for you.
so, on K-7, it's rather cumbersome if you forget to push the RAW button to get both formats recorded, which i often do, and get only the JPG ones, not both JPG + RAW!
right?
i hope my point is now as clear as what the K-7 manual itself says it too: it can't be done! (yes, believe it or not dear aurele, i've been reading technical manuals of almost everything since even before you were born!) ;-)
in fact, since this was a drag on the K-7, Pentax decided to let K-5 not suffer from that truly bad shortcoming later when manufacturing the latter ...
i'm sure this can be done on K-7 too, via firmware upgrade or something along those lines but is there such a solution?
and please respond if you do get the question, if not, just let me know and i'll try to put it differently!
many thanks
