Samsung S850 Digital Camera

I bought this camera because of Samsung's reputation and past experiences with their products.
I have had this camera for about 4 months, and I am ready to go back to my Pentax. It has about 1/2 second delay when the shutter release is pressed, and any delay is totaly unacceptable regardless of what is considered good on this site. My Pentax is over 5 yrs old, and has no delay. That is why you pus the button halfway down before shooting. That sets the exposure and focus, as well as determining wheather to flash or not.
