I had an accident before Christmas with my 24mm PC shift lens. A bent filter ring and the tightening screw sheared off . So it was off to LTR, who do Nikon repairs in Italy. I bought a SH beater, when I found parts had to come from Japan. I will not lose much reselling it.
So four months later my favorite lens returned home with new screws, movement blocks and filter ring. They also serviced the focus ring. All for a reasonable €360. I have an almost new lens, that has been well centred.
Well done LTR. It is nice to have positive things to say sometimes about manufacturers.
The D850 I was using at the time went back for a checkup and was fine. It came back within a week. Pity they do not seem to have parts in Europe for the more exotic lenses and they seem to arrive by a slow boat from Japan.
