'OVERVIEW OF WEATHER AND WATER
RESISTANT PENTAX RICOH IMAGING
CAMERAS AND LENSES
A growing list of PENTAX photographic products
including DSLR cameras, compact digital
cameras and certain interchangeable lenses have
been specifically engineered to include a
high level of protection
against dust, moisture, rain
and cold temperatures. Water-tight access covers,
gaskets and a generous number of seals in the
construction of the camera and lens body have
expanded how and where t
hese products can be
used.
The current selection of DSLRs from PENTAX offer a
weather, dust and coldproof design to ensure reliable
and consistent performance both in inclement weather
and in those demanding env
ironmental conditions
which would challenge any camera.
From the inside-out, PENTA
X DSLRs are engineered
to be both tough and dependable. Photographers
from around the world report t
he ability to continue to
shoot stunning images while enduring the harshest
elements nature has to offe
r, including rain, sleet, and
snow.
As hardy as the photographers who use them,
PENTAX weather-resistant DSLRs have acquired a
well-earned reputation for re
liability due to their robust
construction and extensive use of special protective
seals in the camera bodies.
PENTAX DSLR seals are a story
in themselves. Designed to be
both lightweight and durable,
PENTAX takes great care with
engineering and choice of materials. The access doors and
ports on the camera body ar
e manufactured from a flexib
le, tough rubber, and the seams and
joints on the body are protected with seals m
ade from high-density
foam rubber. The seal
system tolerates temperature changes while still
providing effective water-resistant barriers.
To match these exceptionally well-protec
ted cameras, PENTAX has
created a series of lenses design
ed to deliver dependable, high-quality
results in all types of adverse weather or environmental conditions.
Grouped into two categories according
to the type of weather-resistant
construction, both groups of lenses
feature a level of
protection from
weather not found in ordinary lenses.
First are the PENTAX DA* (DA Star) lenses. Re
cognized for their outstanding image quality
and advanced features, PENTAX DA* lenses handle harsh weather with ease. Because each
part of a DA* lens that might contact the environm
ent is tightly sealed, it is ideal for use in
dusty or rainy conditions. PENTAX DA* lenses are categorized both dustproof and water-
resistant.
The next category of “all we
ather” PENTAX lenses is designated “WR”. These affordable
lenses utilize a simplified w
eather-resistant construction (sim
ilar to the sealing technology
used in DA* lenses) which makes it diffi
cult for water to enter the lens.
PENTAX WR lenses are cat
egorized weather-resistant.
In addition, PENTAX RICOH IMAGAING
COMPANY offers the latest generation of
waterproof, dustproof, shockproof and
coldproof compact digital cameras. These
cameras combine outstanding optical
performance and the latest technology in
rugged, durable, colorful bodies.
Conforming to JIS Grade 8 for water-
resistance (capable of sustained
submersion) and JIS Grade 6 for dust-
resistance (dust-tight,
no ingress of dust),
the latest PENTAX RICOH IMAGAING
COMPANY’S compact waterproof cameras
consistently rank among the best in their
class for toughness, features,
performance and overall design.
Note: PENTAX DSLRs and lenses which are
designated as dust, water or weather-resistant are
not graded using JIS classifications.
Note: The Japanese Industrial Standard (JIS) Codes
are a set of tests used to verify the protection of
electrical equipment against the ingress of water
and/or dust. The different levels of protection are
expressed as different grades (or classes).'
