How many people bought the D600 knowing that there MIGHT be a oil issue on the sensor? I had an issue when I bought my D5100 and sent it to Nikon and got a new camera and lens in 3 weeks! I've had a great experience with Nikon so far.
I did, and mine does have the oil issue. mine was also a factory refurb too (ie checked out by nikon). It's annoying, it gets dirty VERY fast, and is very annoying to clean (usually taking multiple wet swabs). That said I love the camera. It's an awesome mix of IQ, low light, and light weight (yes this is a plus for someone who actually uses their camera professionally... but that's another rant). I just have to clean it WAY more often than i'd like, and it takes a lot longer than i'd like.
the oil doesn't annoy me nearly much as all of the people WITHOUT D600's who like to chime in about the problem being hyped. this thread is a perfect example, look at all of those who felt the need to say something about the problem being hype... how many own d600's? I actually have a dog in this fight, and i don't complain about the problem nearly as much as these guys b*tch about it not being a problem.
not saying that they can't potentially have decent 2nd hand info or research... but none have actual experience either positively or negatively in relation to the problem. in the end they're just parroting what they've heard... aka hype. not surprisingly it's the same people who like to give lens reviews/advice about lenses they've never used.
IMO it's wrong to say "it's just dust", it's not. or that "it clears up after xxx shots", because it's still pretty strong after dozens of 1000's of shots, perhaps it got better, but certainly not gone. and i have no idea where people are getting their #'s concerning "few isolated incidents". It certainly affected a good chunk of the early products which was clearly evident by the first initial lensrental report that started the whole issue. a lot of what's being said is from people who have absolutely no clue or experience with what they're talking about. funny how they're the ones complaining about hype.
back to the OP no i haven't lost faith. a company like this isn't going to recall all their cameras for something that's really not catastrophic. Like i said I one one with the problem, and I knew this when i still had a chance to return it. I didn't, and still wouldn't today. Nikon makes great cameras, imo better than the other options out there dust/oil or not.
