A Peek Inside the AF-S Nikkor 120-300mm f/2.8 FL ED SR VR

By

We’ve wanted to look inside the Nikkor AF-S 120-300mm f/2.8 FL ED SR VR lens. When we took apart a Z lens recently, we found Nikon had moved on from their ‘classic’ internal optomechanical and electrical design for a neat, modern design.

Practical Use of Field Curvature Graphs – the 50mm Primes
