Summary: I bought this D600 from a guy who bought it factory refurbished from Nikon. Apparently, he shot off about 2,200 pics without any hint of the notorious dust spots issue. Nevertheless, he sent the camera back to Nikon to have the shutter replaced before putting it for sale on Ebay. (He did NOT test the new shutter before putting it on Ebay, apparently in an effort to keep the shutter count low as possible before selling.
Summary: The dust issue continues to reoccur OVER and OVER. Local camera shop will clean sensor for $90. EACH TIME this happens I need to fork over $90??? And it happens frequently. Every 1000 shots or so. I won't rehash what others have said about Nikon and the D610 but this is so disappointing after spending $2K on this body.
Excerpt: This camera is amazing. It takes amazing photos. But after 1000 shots oil on the sensor is clearly apparent on every photo. I have been through 3 of these cameras and I'm done. Switching to a canon 6d. Adorama is great! They have exchanged every camera without question. Thank you adorama, I love you!
Pros: Easy To Use, Fast / Accurate Auto-Focus, Fast Shutter Speed, Good Image Quality, Good Image Stabilization, High ISO Performance, Large Clear LCD
Summary: I purchased the D600 body about a month ago. I had used all my savings that I have been saving for about 2 years. I was very excited to buy a full frame camera after having used D3000 for about 5 years of my life. In the beginning, when I used the camera with Tamron lenses to take event pictures it did its job. The quality was superb and the colors as well as the focusing capability were excellent.
Summary: I purchased this camera to travel to South America. I had used a D7000 for a year and I have 4 other Nikon SLR bodies. Two days into the trip spots started showing up. These are not dust spots since you can see them when the mirror is locked up and they appear as small smudges on the sensor. I finally did a wet cleaning of the sensor with swabs designed for that and most of them came off. They seem to be back now. What a disappointment from Nikon.
Summary: I was a first adopter and bought my d600 in September 2012. I like to shoot long exposure which accentuates a dirty sensor After a month I finally noticed spots/oil and sent the camera to Nikon for repair and in a week they returned the camera. The spots--dust, oil, whatever were fainter but still there. I sent the camera back a second time. The second return from Nikon also had a dirty sensor.
Dust/oil problems - DO NOT BUY until Nikon fixes the issue

Summary: Nikon has finally admitted to the well-documented problems with spots on the D600 sensor. Look at sites like dpreview, lens rentals, and the reviews here and you will see this is a real and serious problem. My D600 was sent in for service three times and was not fixed, so they do not have a solution for it yet. I was getting spots on my sensor every 200 shots and these spots would not come off with a rocket blower.
Summary: I'm writing this review at the point where I'm returning the 2nd body I had back to Amazon. There are two parts to understand, the camera itself, and the issue plaguing majority of these bodies. The first body I had was bought in September 2012, and after buying, I immediately went on an international trip, which was going to be several months, since the body had just come out, and as I was traveling I had not heard about the sensor dust issue.
