My new Nikkor 10-24 mm has bad extreme corners resolution (Imatest MTF 0,17 only at radius 12,7 mm instead 0,43 Nikon web specification).
The resolution at all corners is appr the same, therefore I think that it is not the problem of lens centering. I am persuated that I have bought defective copy of Nikkor 10-24 mm. The practical test shots are in attachment (1:1 crops of center + all corners + all extreme corners).
Prague Nikon service recommended me to send lens for warranty repair (repair shoud be made at Nikon Europe Service, specialised for 10- 24 lens, after Nikon internals tests)
Has somebody experience with repair of simillar problem (Nikkor 10-24 symetrical poor extreme corners resolution)?
I am afraid to send new lens for such repair because I could not realize how could it made. I am afraid that the result of "repair" could be worse than the present state.
Many thank for relevant comments.
