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

The AF-S Nikkor 20mm f/1.8G ED is a fast, ultra-wide-angle prime for full-frame Nikon DSLRs. It combines a wide field of view with a bright aperture, making it highly effective for astrophotography, wide-angle environmental portraits, and low-light architecture. The optical formula includes two ED glass and two aspherical elements to ensure sharpness and minimise distortion across the frame. Check the front filter thread for any damage, as this lens is frequently used with large filters for landscape work. The SWM autofocus should be silent and immediate. SDS checks for any decentring, which can sometimes occur in wide-angle primes if they have been subjected to impacts. The rubber zoom ring should be tight against the barrel, and the rear weather seal should be free from nicks or tears.
