Nikkor 24-70 repair cost.
This is just for reference, as I found it difficult to find information before I got my quote. I took my 24-70mm (original, non-VR) in for service as the zoom ring was very stiff. They said it needed a new helicoid, SWM replacement and tube. The price from Official Nikon Service Hong Kong was around $US 900. The warranty would have only been 6 months for the new parts. I declined the repair.
