Definitions of ‘Haze’ and ‘Dust’ Ratings

[Definition of “thin haze” and “haze” for Lenses and Other Items at Our Store]

As a fundamental policy of our store, we do not list products with visible cloudiness that would interfere with photography (i.e., cloudiness that can be confirmed with the naked eye).

Based on this, the definitions for the terms “slight haze” and “haze” as used in our store's product listings are as follows:

“thin haze” ... A haze appearing sparsely across the entire surface of lenses, etc.; a haze confined to specific areas; or a state where a very faint haze appears across the entire surface when illuminated by an LED light.

“haze”... When illuminated with an LED light, the lens or other components appear whitish over a wide area.

In any of the above conditions, we have tested the camera at our store and confirmed that it functions normally for regular shooting.

[Definition of dust and debris found in lenses at Our Store]

As a general rule, second-hand lenses will contain some dust and debris.

As a fundamental policy of our store, we do not list products that contain dust or debris (which may appear in the photographs) that could affect the quality of the photos.

With this in mind, the definitions of ‘small dust’ and ‘dust’ as used in relation to the items listed in our shop are as follows:

“small dust”… Where there are approximately 1 to 5 slightly noticeable specks of dust, or where extremely fine dust is present throughout the lens (limited to cases where the amount of dust exceeds that typically found in lenses of a similar age).

“dust”… Although this does not affect filming, it contains more dust than “small dust”

*We carry out our LED light inspection by shining a light of approximately 35 lumens onto the lens surface from a distance of around 15–20 cm. This is because this environment makes it easiest to assess the condition of the lens, and the light intensity is sufficient to determine whether it will affect photography.
