For those who want the best in protection and only protection
Exclusive chemically hardened crystal clear optical glass places a
transparent shield in front of the lens for superior lens protection in
all situations. The HD2 Protector glass has no optical properties acting
like it is not even there for shooting purposes.
Protection for your valued optics
The Hoya HD2 Protector is the ultimate in clear filters. It has no
effect on sharpness, color balance or performance of the lens in any
way. However, keeping on the lens constantly will protect the front
element of the lens from damage due to dirt, sand, spray or knocks and
scratches.”
The HD2 series plus the EVO and NXT series filters are manufactured
by Hoya exclusively for distribution in the United States of America.
*Neither Hoya nor it's US distributor recommend exposing camera gear
to wind-blown sand, dirt or rain. While the filter can handle these
conditions other pieces of equipment may not. Use common sense and take
precautions when photographing in harsh conditions or inclement
weather.
