DSC F717 owners are you all aware that in some F717's the Halogram AF, when used in low light will produce blured images.
I noticed it with mine so I went to the www.sony.com web site, then went to digital cameras downloads, and found out that this is a problem with many DSC F717's
Sony is more than happy to arrange and pick it up and express deliver it to there technicians for correction.
Also note that not all DSC F717's are affected. Sony has listed all the serial numbers which have this problem, my camera fell in the category, so I'll be sending mine in in a couple of days.
