Image transformation routines are a bit more CPU intensive than exposure calculation and power management. Previously 4 bit data channels and 1 KHz system clocks were more than enough to drive a film camera. The hardware demand peaked with the F5 that included a 16 bit processor. Nowadays you can't even touch a megapixel in real time without processors ticking in MHz. I believe that Henry is right: Pentax needed a stronger foothold in electronics. That 0.01s shutter lag in Optio-S must be largely due to the Sanyo components. Servus, Alin
