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:
- Screw -in (HR, HN) screws into the front of the lens: HR rubber fold back over the lens when not in use.
- Bayonet (HB) twist-lock mounting for extra security.
- Snap-on (HS) snaps on front of lens with spring type retainer ring; and reverses in place for storage.
- 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
