How much should a Da*200 lens be stopped down before it gives sharp IQ?
Feb 17, 2013

I have had my new DA* 200 lens checked by Pentax and they say it is ok. They have calibrated it to my K30 yet it does not begin to give sharp iq until it is stopped down to f4. For what is supposed to be a pro quality lens and described as giving excellent IQ I find that unacceptable or am I expecting too much???
