Nikon HS-9 snap-on Lens Hood for AF 50mm f1.4

Nikon offer a comprehensive range of hoods which minimize stray light; thus, helping to reduce flare and eliminate ghost images; and protect the lens.

There are 4 styles of hood:

1. Screw -in (HR, HN) screws into the front of the lens: HR rubber fold back over the lens when not in use.
2. Bayonet (HB) twist-lock mounting for extra security.
3. Snap-on (HS) snaps on front of lens with spring type retainer ring; and reverses in place for storage.
4. Slip-on (HK) slips over the front of the lens; and tightens in place with knurled screw and retaining ring - used with wide zoom and ultra wide lenses
