This is not a repair thread, but there is surely interest in Manual Focus lens repair. I had sent my 15mm 3.5 ais back to Nikon in California, as it is the only lens I own that failed to work well with the D800. I also own a 15mm 5.6 that is excellent with the D800. After Nikon cleaned the 15mm 3.5, it worked quite well, but still showed haze in one element.
I sent the pictures below to Nikon, one is the 15mm 3.5 with the remaining haze, and the other my perfectly clean 15mm 5.6. Upon Nikon seeing these pictures, I was provided a no charge return shipping label and a no cost repair estimate.
Last Friday I had a call from a Nikon Service supervisor with a repair technician on the side, the supervisor seemed a little upset because the lens was passing all their testing, but they could not fully repair it for lack of lens parts and he was not sure which element the haze was on. The technician identified the lens group with the haze, I basically asked them to do the best they could. Today checking on the lens repair status it shows "On Hold for Parts".
We will see what develops, hopefully they found lens elements somewhere but I will not know until I get it. I felt this was the last chance in time to get this lens to perfection, before all parts become unavailable, after that in a dry climate it should last 100 years more. (No kidding, I use 54 year old Nikon F lenses that are like new)
