My sad saga with the Nikon D600 continues. Back in April, 2013 I had significant spotting on my sensor after just 4 months of use. At that time I sent the camera to Nikon Canada and they cleaned the sensor and replaced the shutter.
4 months later in late September, 2013 the problem had returned - significant spotting at small apertures (which I use frequently for landscape photography) and larger “blobs” at wider apertures.
The D600 is set to be shipped back to Nikon Canada this week - I’ve never had this kind of problem with a camera before, having a “semi professional” sensor professionally cleaned every 4 months is a bit much. What happens when the warranty runs out?
