Whoa, whoa, whoa. That's NOT an incompatibility. I'm not saying your overall point is wrong, but Pentax is under NO obligation to make its new bodies conform to older products FROM OTHER MANUFACTURERS. This is an unreasonable standard to hold them to, and certainly not a valid example of incompatibility. --Mike
