Yes, I read through it all, but the linear/non-linear diaphragm control is only important if the camera is trying to set the position of the diaphragm (ie. Program or shutter-preferred autoexposure). For matrix metering it just needs to know what the mazimum and minimum possible apertures are. The information about where the diaphragm is actually *set* at any given time comes through the stop-down *indicator* (on the opposite side of the lens from the diaphragm actuator) and this didn't change. -- Mark Roberts www.robertstech.com - This message is from the Pentax-Discuss Mail List.
