Supposing it was strictly an economic decision on Pentax's part: It's not just the $5 part (if that is indeed the cost of the thing). There's the little screws, the rest of the mechanism to operate the part, the electrical circuitry to operate the mechanism, the support stuff for the electrical circuitry (power needs, circuit board additions etc) and the labor costs to put it all into the camera. I think they saved a hell of a lot more than $5 per body. We also don't know what their tooling costs were. Maybe this change allowed them to use simpler cheaper tooling. Parts may have been stamped three times instead of six because of the change. Pentax is trying to compete in a tough market and they had to hit a competitive price point. They decided that they would gain market advantage by building the cameras cheaper and the cost advantage would offset the limited functionality with old lenses. There is still the open question as to whether there was an engineering advantage with the change. Tom Reese
