KZMike: So why does Pentax continue to NOT have any but fixed LCDs on the back side of their SLRs. . . would have purchased a Pentax years ago, but have waited for something to change. Its time for a SLR and I leaning to Sony. . . come on Pentax
I may be wrong but I'm pretty sure it is related to the weather-proofing of the body. Having a screen that articulates adds too many places that water/dust, etc can enter. Other weather rated cams, like the Sony A77, have articulating screens but are not rated for as severe weather as the Pentax. It's sort of like a water "resistant" watch as opposed to a "water proof" watch.
Just my opinion
