It appears that a number of Class Action lawsuit’s have been filed as a result of consumer experiences with Nikon’s D600. If you are interested to follow this you can read about it here, here, here, here, here, here, and here. It’s all a bit messy really and no doubt the problem may well be compounded by the same issue showing up on the D610.
As for me, I appear to be set for protracted run around with Harvey Norman Penrith in terms of getting a satisfactory resolution i.e., refund or appropriate replacement and by that I mean a camera / camera body that does not have this ongoing issue.
About a week ago ( 21st July) my D610 made it back from Nikon Sydney with a new shutter mechanism to replace the original that came with the replacement camera from Nikon Sydney via Harvey Norman (more or less). I’d love to say I have the confidence that this issue will not resurface again but unfortunately this is not the case. It’s such a weird situation to be in. I’d love to be able to load files from the SD cards and not even have the thought cross my mind that the images will somehow show contamination on the sensor. After 17 months of nothing but one problem after another (to date five shutter mechanisms and two cameras) it’s going to take some serious consistency from the D610 to rewire that mindset.
