The Nikon 85mm f/1.8G AF-S is a versatile, compact, fast-aperture lens for Nikon DSLRs and a great low-cost alternative to the 85mm f/1.4G. Key features include:
Excellent for portrait, indoor-sports, and street shooting
Fast, silent autofocus with full-time manual focus
FX and DX compatible
Excellent Image Quality in a Compact Build. The Nikon 85mm f/1.8G AF-S’s reduced size and weight make it easy to keep in your bag at all times, yet it still offers fantastic image quality. The f/1.8 aperture allows for smooth background blur and subject isolation, making this lens perfect for portraiture. It’s compatible with both FX and DX cameras, including those without autofocus motors in-camera (such as the D3100 and D5100).
Fast, Silent Autofocus. This lens has full-time manual focus for easy adjustment, as well as a dedicated AF/MF switch for quickly changing to full manual focus. It’s great for video as well, using Nikon’s Silent Wave Motor to provide fast, silent autofocus.
