Nikon announces AF-S Nikkor 20mm f/1.8G ED

Nikon has launched the AF-S Nikkor 20mm f/1.8G ED for FX and DX format Nikon cameras. It updates the existing AF Nikkor 20mm f/2.8, which lacked an internal focus motor for use with entry-level Nikon DSLRs. Using 13 elements in 11 groups, it features a Nano Crystal Coat and offers a minimum focus distance of 0.2m. The AF-S Nikkor 20mm f/1.8G ED will be available in September for $799.95.
