What kind of experience have you had with Nikon's service department. My 5100 is out of warranty so I will have to pay for repairs. My problem is "soft focus" which actually seems to be due to focus being behind the point where both auto focus and the manual range finder say it is in focus. In many of the pictures, when I looked closely, there did seem to be a point of crisp focus that was behind what I was focusing on. (No, it's not operator error!)
As I see it, one of three things can happen. They can fix the problem, they can say they fixed the problem when they didn't and they can say there is no problem.
Is it worth sending back to Nikon, or should I just go out and buy a Cannon. (I keep having this recurring daydream of buying a Cannon, mounting the d5100 on a tripod, mounting the Canon on a tripod focused on the Nikon and starting a video and making a video of me puting a 308 rifle bullet throught the Nikon.)
