Blow dirt and dust by a blower or wipe with a cleaning paper or cloth, etc.
For Heavy Stains
For heavy stains, use lens cleaning liquid and a cleaning cloth or paper, etc.
Care should be taken, as using an abrasive lens cleaner might result in removal of the coating.
Cautions in Conducting Maintenance
Never use water or detergent for cleaning the filter.
When not used, store the filter in the filter case, in order to prevent adhesion of dust, and scratches.
CPL Filter - The Angle between the Sun and the Object
The Angle between the Sun and the Object
For Landscape Photography
The polarizing effect is maximized when the direction of the sun makes a right angle with the direction of the lens (direction of shooting).
For Water Surface Photography
The reflection is best suppressed when the direction of the lens makes an angle of 30-40 degrees with the reflecting surface.
How to Use the Triangular Mark on the Filter Frame in connection with the Position (Angle) of the Sun
Please rotate the triangular mark on the filter frame in accordance with the direction of the sun.
CPL Filter - Effective Technique
When changing the composition of a photo vertically or horizontally
When changing the composition by 90 degrees from horizontal to vertical, also turn the front ring of the PL filter by 90 degrees.
Effective on a rainy day or a cloudy day
The PL filter is effective on a sunny day as well as a rainy day or a cloudy day. Especially on a rainy day, a object such as autumn leaves will be more brilliant by removing surface reflections with a PL filter.
About filter factor
Installation of a PL filter results in reducing exposure value. Be careful when taking a photo with the manual mode.
A PL filter will deteriorate due to its structure. PL filters, if degraded, will become reddish, instead of an original grey color. It is recommended that a new PL filter be purchased every 4 to 5 years if you are serious about your work.
Prevents Adhesion of Dirt and Dust, etc.
Prevents adhesion of fine dirt and dust by reducing electrostatic charge. Dirt/dust can be easily blown off
by a blower, etc., thereby supporting smooth cleaning.
Allows Smooth Shooting Even at Waterfronts or under Rainy Conditions
The effect of a water repellent coating repels water droplets. This makes it easy to blow off water droplets
if they attach to the filter.
Fingerprints can be Easily Wiped Off
Oil repellent coating resists adhesion of stains to the lens, and if you unintentionally touch the lens,
the stains can be wiped off easily, thereby enabling easy care.
Special Coating Preventing Deterioration in Image Quality
Reduces reflection further by increasing coating layers.
Optical Finder is Bright and Easy to See
Focusing is easier than with conventional polarizing filters, so the polarizing effect can be verified more
easily. Fine expression is possible as the shadow portions of the subject aren’t lost as easily.
Reduces Internal Reflections
Flare and ghosting are reduced by reducing internal reflections with blackened outer rim of the glass.
Specially Designed Frame for Preventing Deterioration in Image Quality
Light-blocking Ridge is added to reduce diffused reflections.
Pursues Higher Image Quality and Easier Handling
Reduces flare and ghosting and supports filter attachment.
Frame Design with Extremely Low Vignetting
Smooth Attachment to / Detachment from the Lens
Reducing strong biting of filter frame for lens during the shooting allows smooth attachment to / detachment from the lens.
