SDM Autofocus Failure Survey

By PF Staff in Third-Party Announcements on Jan 28, 2012
We have recently launched a survey to help us determine whether or not the reliability of Pentax's SDM (supersonic) autofocus system is improving over time.
Take the survey here- it's quick and anonymous.
Thanks for your help in this study!
