Hoya 49mm Close-Up Kit
(+1,+2,+4) HMC (Multi-Coated): Hoya 49mm Close-Up Kit is a set of three filters that is designed for
close-up photography. Each filter has a power of +1, +2, or +4, and can be used
separately or in combination to photograph small objects such as flowers and
insects at a close range. These filters use Hoya Multi-Coated technology to
reduce flare and ghosting while maintaining an average light transmission of
97%. Close-up filters allow you to get closer to the subject. With close-up
filters depth of field tends to be very shallow and it is recommended to shoot
with smaller apertures for greater focus. The ring is made of aluminum with a
threaded front so the filters can be combined.
