Hello all:
I have a problem with my D600. With a large selection of lenses, OEM and third-party, if I shoot a flat object in landscape orientation (tripod, camera level), the top of the image is invariably softer than the bottom. The difference is not small. I've come to be fairly sure that the sensor is somehow tilted. The lens mount is secure, no loose screws, and the camera shows no sign of any impact damage--not even a scratch. I called Nikon repair, and they suggested I try a two-button reset, which sounds silly. If that fails, they want me to send a few sample images.
Two questions for this group. Has anyone seen or heard of this problem? If so, what was done about it, if anything. Is there any possibility that a reset would make the slightest difference? Attached are two 100% screen grabs to demonstrate the problem.
