series 9 filter

[phil sweeney]

Greetings all!

I am looking at a Tiffen filter at the KEH website. It is listed as "ser 9 yel 1." Noone at KEH or tiffen can tell me if this is a K1 (#6) filter. Appreciate if anyone can tell what wratten number filter this is?

thanks

I have a Yel 2 which is like a K2.

Yes, Phil,

A Yellow 1 is the same as a Wratten #6 filter. A Yellow 2 is the same as a Wratten #8 (K2).
