I think at this point we are all going in circles. I own a D600 with oil splatter and the next guy owns a d800 with left focus. It is like I have skin cancer and it has caused me problems and the next guy is like I have aids and am dying you are still alive. Maybe it is I have suspicious mole that can be removed and the next guy has skin cancer. Either way each persons problems are relevant to how it impacts them. I dont expect anyone to feel sorry for me but dont make it seem like it is not an issue it is. I cant believe I am going to quote lens rentals after I slammed them for the initial report but they have the issue and made a blog about it and said it is not normal and that over time it will get better. Over time is important because how long is that time? Sorry you cant tell me right? So either way it is poor QC and we cant all sell our working used stuff and take a risk with someone elses possibly damaged used stuff just to switch brands.
