Originally posted by iggy373 is there any risk to downloading this update? Like is there some chance that the original firmware will be better in the long run and this one may be buggier somehow? If so, are you able to go backwards and load the original?
AFAIK, there is no way to back up or restore firmware 1.0. I may be wrong though.
If that is the case, then an update is risky because you can't roll-back to the previous version.
However, it is only a camera. The worst thing that can happen is that it will be bricked, in which case -> Pentax distributor.
Also it is only a minor - not even a full point - upgrade. One presumes therefore that it doesn't change things around an awful amount, and so may therefore be low-risk to implement.
