My son's two year old K-50 developed the aperture block problem so I told him he had to send it in for repair on the extended warranty. Since his June schedule only has about a week at home. he brought it and handed it off to me to take care of the return. I went online and got the shipping label and shipped it off the next evening (June1). It was delivered to Precision on Friday afternoon (June 3). Thursday afternoon (June 9) Precision called and said my Credit Card was bad. I think the credit card was still in the system from a couple years ago. I gave her the correct number and she mentioned about an estimate (ut-oh!) I told her that it should be under extended warranty, she said they did not have the warranty information (it was with the same paper that they got my phone number from, they somehow lost it). Anyway she asked if I could email it in which I did after getting home from work. They called again the next day and said they had everything, the warranty work was approved, and the camera would be fixed withing a week. I checked the status again Friday night, still showing in repair, this morning just for the heck of it I checked again and whoa! Now as long as it is fixed correctly, and it they should be able to do this repair in their sleep, I'll be very happy.
