I see pentax has created a new version. Is an upgrade needed? Is it really necessary?
sorry for my poor english
There are no known reasons (bugs) not to in the firmware update, so IMO at worst it's neutral and at best you'll benefit. Besides squashing some early issues with KP firmware the most recent update includes added functionality with some of Pentax latest lenses so if you're contemplating a 50-300 PLM or the newish HD FA50 1.4 you absolutely should update.
Oh and by the way, the only one you need to apply is the latest one which includes everything from the previous updates as well.
